Wearable Hub: Getting the Ball Rolling


After years of hype, wearable devices are happening. What wearable computing lacks is a way to integrate devices into a broader system.


  • For the past two months or so, I’ve been taking notes about this “wearable hub” idea (started around CES’s time, as wearable devices like the Pebble and Google Glass were discussed with more intensity). At this point, I have over 3000 words in notes, which probably means that I’d have enough material for a long essay. This post is just a way to release a few ideas and to “think aloud” about what wearables may mean.
  • Some of these notes have to do with the fact that I started using a few wearable devices to monitor my activities, after a health issue pushed me to start doing some exercise.
  • I’m not a technologist nor do I play one on this blog. I’m primarily an ethnographer, with diverse interests in technology and its implications for human beings. I do research on technological appropriation and some of the course I teach relate to the social dimensions of technology. Some of the approaches to technology that I discuss in those courses relate to constructionism and Actor-Network Theory.
  • I consider myself a “geek ethnographer” in the sense that I take part in geek culture (and have come out as a geek) but I’m also an outsider to geekdom.
  • Contrary to the likes of McLuhan, Carr, and Morozov, my perspective on technology and society is non-deterministic. The way I use them, “implication” and “affordance” aren’t about causal effects or, even, about direct connections. I’m not saying that society is causing technology to appear nor am I proposing a line from tools to social impacts. Technology and society are in a complex system.
  • Further, my approach isn’t predictive. I’m not saying what will happen based on technological advances nor am I saying what technology will appear. I’m thinking about the meaning of technology in an intersubjective way.
  • My personal attitude on tools and gadgets is rather ambivalent. This becomes clear as I go back and forth between techno-enthusiastic contexts (where I can almost appear like a Luddite) and techno-skeptical contexts (where some might label me as a gadget freak). I integrate a number of tools in my life but I can be quite wary about them.
  • I’m not wedded to the ideas I’m putting forth, here. They’re just broad musings of what might be. More than anything, I hope to generate thoughtful discussion. That’s why I start this post with a broad statement (not my usual style).
  • Of course, I know that other people have had similar ideas and I know that a concept of “wearable hub” already exists. It’s obvious enough that it’s one of these things which can be invented independently.

From Wearables to Hubs

Back in the 1990s, “wearable computing” became something of a futuristic buzzword, often having to do with articles of clothing. There have been many experiments and prototypes converging on an idea that we would, one day, be able to wear something resembling a full computer. Meanwhile, “personal digital assistants” became something of a niche product and embedded systems became an important dimension of car manufacturing.

Fast-forward to 2007, when a significant shift in the use of smartphones occurred. Smartphones existed before that time, but their usages, meanings, and positions in the public discourse changed quite radically around the time of the iPhone’s release. Not that the iPhone itself “caused a smartphone revolution” or that smartphone adoption suddenly reached a “tipping point”. I conceive of this shift as a complex interplay between society and tools. Not only more Kuhn than Popper, but more Latour than Kurzweil.

Smartphones, it may be argued, “happened”.

Without being described as “wearable devices”, smartphones started playing some of the functions people might have assigned to wearable devices. The move was subtle enough that Limor Fried recently described it as a realization she’s been having. Some tech enthusiasts may be designing location-aware purses and heads-up displays in the form of glasses. Smartphones are already doing a lot of the things wearables were supposed to do. Many people “wear” smartphones at most times during their waking lives and these Internet-connected devices are full of sensors. With the proliferation of cases, one might even perceive some of them as fashion accessories, like watches and sunglasses.

Where smartphones become more interesting, in terms of wearable computing, is as de facto wearable hubs.

My Wearable Devices

Which brings me to mention the four sensors I’ve been using more extensively during the past two months:

Yes, these all have to do with fitness (and there’s quite a bit of overlap between them). And, yes, I started using them a few days after the New Year. But it’s not about holiday gifts or New Year’s resolutions. I’ve had some of these devices for a while and decided to use them after consulting with a physician about hypertension. Not only have they helped me quite a bit in solving some health issues, but these devices got me to think.

(I carry several other things with me at most times. Some of my favourites include Tenqa REMXD Bluetooth headphones and the LiveScribe echo smartpen.)

One aspect is that they’re all about the so-called “quantified self”. As a qualitative researcher, I tend to be skeptical of quants. In this case, though, the stats I’m collecting about myself fit with my qualitative approach. Along with quantitative data from these devices, I’ve started collecting qualitative data about my life. The next step is to integrate all those data points automatically.

These sensors are also connected to “gamification”, a tendency I find worrisome, preferring playfulness. Though game mechanics are applied to the use of these sensors, I choose to rely on my intrinsic motivation, not paying much attention to scores and badges.

But the part which pushed me to start taking the most notes was that all these sensors connect with my iOS ()and Android) devices. And this is where the “wearable hub” comes into play. None of these devices is autonomous. They’re all part of my personal “arsenal”, the equipment I have on my me on most occasions. Though there are many similarities between them, they still serve different purposes, which are much more limited than those “wearable computers” might have been expected to serve. Without a central device serving as a type of “hub”, these sensors wouldn’t be very useful. This “hub” needs not be a smartphone, despite the fact that, by default, smartphones are taken to be the key piece in this kind of setup.

In my personal scenario, I do use a smartphone as a hub. But I also use tablets. And I could easily use an existing device of another type (say, an iPod touch), or even a new type of device meant to serve as a wearable hub. Smartphones’ “hub” affordances aren’t exclusive.

From Digital Hub to Wearable Hub

Most of the devices which would likely serve as hubs for wearable sensors can be described as “Post-PC”. They’re clearly “personal” and they’re arguably “computers”. Yet they’re significantly different from the “Personal Computers” which have been so important at the end of last century (desktop and laptop computers not used as servers, regardless of the OS they run).

Wearability is a key point, here. But it’s not just a matter of weight or form factor. A wearable hub needs to be wireless in at least two important ways: independent from a power source and connected to other devices through radio waves. The fact that they’re worn at all times also implies a certain degree of integration with other things carried throughout the day (wallets, purses, backpacks, pockets…). These devices may also be more “personal” than PCs because they may be more apparent and more amenable to customization than PCs.

Smartphones fit the bill as wearable hubs. Their form factors and battery life make them wearable enough. Bluetooth (or ANT+, Nike+, etc.) has been used to pair them wirelessly with sensors. Their connectivity to GPS and cellular networking as well as their audio and visual i/o can have interesting uses (mapping a walk, data updates during a commute, voice feedback…). And though they’re far from ubiquitous, smartphones have become quite common in key markets.

Part of the reason I keep thinking about “hubs” has to do with comments made in 2001 by then Apple CEO Steve Jobs about the “digital lifestyle” age in “PC evolution” (video of Jobs’s presentation; as an anthropologist, I’ll refrain from commenting on the evolutionary analogies):

We believe the PC, or more… importantly, the Mac can become the “digital hub” of our emerging digital lifestyle, with the ability to add tremendous value to … other digital devices.

… like camcorders, portable media players, cellphones, digital cameras, handheld organizers, etc. (Though they weren’t mentioned, other peripherals like printers and webcams also connect to PCs.)

The PC was thus going to serve as a hub, “not only adding value to these devices but interconnecting them, as well”.

At the time, key PC affordances which distinguished them from those other digital devices:

  • Big screen affording more complex user interfaces
  • Large, inexpensive hard disk storage
  • Burning DVDs and CDs
  • Internet connectivity, especially broadband
  • Running complex applications (including media processing software like the iLife suite)

Though Jobs pinpointed iLife applications as the basis for this “digital hub” vision, it sounds like FireWire was meant to be an even more important part of this vision. Of course, USB has supplanted FireWire in most use cases. It’s interesting, then, to notice that Apple only recently started shipping Macs with USB 3. In fact, DVD burning is absent from recent Macs. In 2001, the Mac might have been at the forefront of this “digital lifestyle” age. In 2013, the Mac has moved away from its role as “digital hub”.

In the meantime, the iPhone has become one of the best known examples of what I’m calling “wearable hubs”. It has a small screen and small, expensive storage (by today’s standards). It also can’t burn DVDs. But it does have nearly-ubiquitous Internet connectivity and can run fairly complex applications, some of which are adapted from the iLife suite. And though it does have wired connectivity (through Lightning or the “dock connector”), its main hub affordances have to do with Bluetooth.

It’s interesting to note that the same Steve Jobs, who used the “digital hub” concept to explain that the PC wasn’t dead in 2001, is partly responsible for popularizing the concept of “post-PC devices” six years later. One might perceive hypocrisy in this much delayed apparent flip-flop. On the other hand, Steve Jobs’s 2007 comments (video) were somewhat nuanced, as to the role of post-PC devices. What’s more interesting, though, is to think about the implications of the shift between two views of digital devices, regardless of Apple’s position through that shift.

Some post-PC devices (including the iPhone, until quite recently) do require a connection to a PC. In this sense, a smartphone might maintain its position with regards to the PC as digital hub. Yet, some of those devices are used independently of PCs, including by some people who never owned PCs.

Post-Smartphone Hubs

It’s possible to imagine a wearable hub outside of the smartphone (and tablet) paradigm. While smartphones are a convenient way to interconnect wearables, their hub-related affordances still sound limited: they lack large displays and their storage space is quite expensive. Their battery life may also be something to consider in terms of serving as hubs. Their form factors make some sense, when functioning as phones. Yet they have little to do with their use as hubs.

Part of the realization, for me, came from the fact that I’ve been using a tablet as something of an untethered hub. Since I use Bluetooth headphones, I can listen to podcasts and music while my tablet is in my backpack without being entangled in a cable. Sounds trivial but it’s one of these affordances I find quite significant. Delegating music playing functions to my tablet relates in part to battery life and use of storage. The tablet’s display has no importance in this scenario. In fact, given some communication between devices, my smartphone could serve as a display for my tablet. So could a “smartwatch” or “smartglasses”.

The Body Hub

Which led me to think about other devices which would work as wearable hubs. I originally thought about backpackable and pocketable devices.

But a friend had a more striking idea:

Under Armour’s Recharge Energy Suit may be an extreme version of this, one which would fit nicely among things Cathi Bond likes to discuss with Nora Young on The Sniffer. Nora herself has been discussing wearables on her blog as well as on her radio show. Sure, part of this concept is quite futuristic. But a sensor mesh undershirt is a neat idea for several reasons.

  • It’s easy to think of various sensors it may contain.
  • Given its surface area, it could hold enough battery power to supplement other devices.
  • It can be quite comfortable in cold weather and might even help diffuse heat in warmer climates.
  • Though wearable, it needs not be visible.
  • Thieves would probably have a hard time stealing it.
  • Vibration and haptic feedback on the body can open interesting possibilities.

Not that it’s the perfect digital hub and I’m sure there are multiple objections to a connected undershirt (including issues with radio signals). But I find the idea rather fun to think, partly because it’s so far away from the use of phones, glasses, and watches as smart devices.

Another thing I find neat, and it may partly be a coincidence, is the very notion of a “mesh”.

The Wearable Mesh

Mesh networking is a neat concept, which generates more hype than practical uses. As an alternative to WiFi access points and cellular connectivity, it’s unclear that it may “take the world by storm”. But as a way to connect personal devices, it might have some potential. After all, as Bernard Benhamou recently pointed out on France Culture’s Place de la toile, the Internet of Things may not require always-on full-bandwith connectivity. Typically, wearable sensors use fairly little bandwidth or only use it for limited amounts of time. A wearable mesh could connect wearable devices to one another while also exchanging data through the Internet itself.

Or with local devices. Smart cities, near field communication, and digital appliances occupy interesting positions among widely-discussed tendencies in the tech world. They may all have something to do with wearable devices. For instance, data exchanged between transit systems and their users could go through wearable devices. And while mobile payment systems can work through smartphones and other cellphones, wallet functions can also be fulfilled by other wearable devices.

Alternative Futures

Which might provide an appropriate segue into the ambivalence I feel toward the “wearable hub” concept I’m describing. Though I propose these ideas as if I were enthusiastic about them, they all give me pause. As a big fan of critical thinking, I like to think about “what might be” to generate questions and discussions exposing a diversity of viewpoints about the future.

Mass media discussions about these issues tend to focus on such things as privacy, availability, norms, and usefulness. Google Glass has generated quite a bit of buzz about all four. Other wearables may mainly raise issues for one or two of these broad dimensions. But the broad domain of wearable computing raises a lot more issues.

Technology enthusiasts enjoy discussing issues through the dualism between dystopia and utopia. An obvious issue with this dualism is that humans disagree about the two categories. Simply put, one person’s dystopia can be another person’s utopia, not to mention the nuanced views of people who see complex relationships between values and social change.

In such a context, a sociologist’s reflex may be to ask about the implications of these diverse values and opinions. For instance:

  • How do people construct these values?
  • Who decides which values are more important?
  • How might social groups cope with changes in values?

Discussing these issues and more, in a broad frame, might be quite useful. Some of the trickiest issues are raised after some changes in technology have already happened. From writing to cars, any technological context has unexpected implications. An ecological view of these implications could broaden the discussion.

I tend to like the concept of the “drift-off moment”, during which listeners (or readers) start thinking about the possibilities afforded a new tool (or concept). In the context of a sales pitch, the idea is that these possibilities are positive, a potential buyer is thinking about the ways she might use a newfangled device. But I also like the deeper process of thinking about all sorts of implications, regardless of their value.


What might be the implications of a wearable hub?

Handhelds for the Rest of Us?

Ok, it probably shouldn’t become part of my habits but this is another repost of a blog comment motivated by the OLPC XO.

This time, it’s a reply to Niti Bhan’s enthusiastic blogpost about the eeePC: Perspective 2.0: The little eeePC that could has become the real “iPod” of personal computing

This time, I’m heavily editing my comments. So it’s less of a repost than a new blogpost. In some ways, it’s partly a follow-up to my “Ultimate Handheld Device” post (which ended up focusing on spatial positioning).

Given the OLPC context, the angle here is, hopefully, a culturally aware version of “a handheld device for the rest of us.”

Here goes…

I think there’s room in the World for a device category more similar to handhelds than to subnotebooks. Let’s call it “handhelds for the rest of us” (HftRoU). Something between a cellphone, a portable gaming console, a portable media player, and a personal digital assistant. Handheld devices exist which cover most of these features/applications, but I’m mostly using this categorization to think about the future of handhelds in a globalised World.

The “new” device category could serve as the inspiration for a follow-up to the OLPC project. One thing about which I keep thinking, in relation to the “OLPC” project, is that the ‘L’ part was too restrictive. Sure, laptops can be great tools for students, especially if these students are used to (or need to be trained in) working with and typing long-form text. But I don’t think that laptops represent the most “disruptive technology” around. If we think about their global penetration and widespread impact, cellphones are much closer to the leapfrog effect about which we all have been writing.

So, why not just talk about a cellphone or smartphone? Well, I’m trying to think both more broadly and more specifically. Cellphones are already helping people empower themselves. The next step might to add selected features which bring them closer to the OLPC dream. Also, since cellphones are widely distributed already, I think it’s important to think about devices which may complement cellphones. I have some ideas about non-handheld tools which could make cellphones even more relevant in people’s lives. But they will have to wait for another blogpost.

So, to put it simply, “handhelds for the rest of us” (HftRoU) are somewhere between the OLPC XO-1 and Apple’s original iPhone, in terms of features. In terms of prices, I dream that it could be closer to that of basic cellphones which are in the hands of so many people across the globe. I don’t know what that price may be but I heard things which sounded like a third of the price the OLPC originally had in mind (so, a sixth of the current price). Sure, it may take a while before such a low cost can be reached. But I actually don’t think we’re in a hurry.

I guess I’m just thinking of the electronics (and global) version of the Ford T. With more solidarity in mind. And cultural awareness.

Google’s Open Handset Alliance (OHA) may produce something more appropriate to “global contexts” than Apple’s iPhone. In comparison with Apple’s iPhone, devices developed by the OHA could be better adapted to the cultural, climatic, and economic conditions of those people who don’t have easy access to the kind of computers “we” take for granted. At the very least, the OHA has good representation on at least three continents and, like the old OLPC project, the OHA is officially dedicated to openness.

I actually care fairly little about which teams will develop devices in this category. In fact, I hope that new manufacturers will spring up in some local communities and that major manufacturers will pay attention.

I don’t care about who does it, I’m mostly interested in what the devices will make possible. Learning, broadly speaking. Communicating, in different ways. Empowering themselves, generally.

One thing I have in mind, and which deviates from the OLPC mission, is that there should be appropriate handheld devices for all age-ranges. I do understand the focus on 6-12 year-olds the old OLPC had. But I don’t think it’s very productive to only sell devices to that age-range. Especially not in those parts of the world (i.e., almost anywhere) where generation gaps don’t imply that children are isolated from adults. In fact, as an anthropologist, I react rather strongly to the thought that children should be the exclusive target of a project meant to empower people. But I digress, as always.

I don’t tend to be a feature-freak but I have been thinking about the main features the prototypical device in this category should have. It’s not a rigid set of guidelines. It’s just a way to think out loud about technology’s integration in human life.

The OS and GUI, which seem like major advantages of the eeePC, could certainly be of the mobile/handheld type instead of the desktop/laptop type. The usual suspects: Symbian, NewtonOS, Android, Zune, PalmOS, Cocoa Touch, embedded Linux, Playstation Portable, WindowsCE, and Nintendo DS. At a certain level of abstraction, there are so many commonalities between all of these that it doesn’t seem very efficient to invent a completely new GUI/OS “paradigm,” like OLPC’s Sugar was apparently trying to do.

The HftRoU require some form of networking or wireless connectivity feature. WiFi (802.11*), GSM, UMTS, WiMAX, Bluetooth… Doesn’t need to be extremely fast, but it should be flexible and it absolutely cannot be cost-prohibitive. IP might make much more sense than, say, SMS/MMS, but a lot can be done with any kind of data transmission between devices. XO-style mesh networking could be a very interesting option. As VoIP has proven, voice can efficiently be transmitted as data so “voice networks” aren’t necessary.

My sense is that a multitouch interface with an accelerometer would be extremely effective. Yes, I’m thinking of Apple’s Touch devices and MacBooks. As well as about the Microsoft Surface, and Jeff Han’s Perceptive Pixel. One thing all of these have shown is how “intuitive” it can be to interact with a machine using gestures. Haptic feedback could also be useful but I’m not convinced it’s “there yet.”

I’m really not sure a keyboard is very important. In fact, I think that keyboard-focused laptops and tablets are the wrong basis for thinking about “handhelds for the rest of us.” Bear in mind that I’m not thinking about devices for would-be office workers or even programmers. I’m thinking about the broadest user base you can imagine. “The Rest of Us” in the sense of, those not already using computers very directly. And that user base isn’t that invested in (or committed to) touch-typing. Even people who are very literate don’t tend to be extremely efficient typists. If we think about global literacy rates, typing might be one thing which needs to be leapfrogged. After all, a cellphone keypad can be quite effective in some hands and there are several other ways to input text, especially if typing isn’t too ingrained in you. Furthermore, keyboards aren’t that convenient in multilingual contexts (i.e., in most parts of the world). I say: avoid the keyboard altogether, make it available as an option, or use a virtual one. People will complain. But it’s a necessary step.

If the device is to be used for voice communication, some audio support is absolutely required. Even if voice communication isn’t part of it (and I’m not completely convinced it’s the one required feature), audio is very useful, IMHO (I’m an aural guy). In some parts of the world, speakers are much favoured over headphones or headsets. But I personally wish that at least some HftRoU could have external audio inputs/outputs. Maybe through USB or an iPod-style connector.

A voice interface would be fabulous, but there still seem to be technical issues with both speech recognition and speech synthesis. I used to work in that field and I keep dreaming, like Bill Gates and others do, that speech will finally take the world by storm. But maybe the time still hasn’t come.

It’s hard to tell what size the screen should be. There probably needs to be a range of devices with varying screen sizes. Apple’s Touch devices prove that you don’t need a very large screen to have an immersive experience. Maybe some HftRoU screens should in fact be larger than that of an iPhone or iPod touch. Especially if people are to read or write long-form text on them. Maybe the eeePC had it right. Especially if the devices’ form factor is more like a big handheld than like a small subnotebook (i.e., slimmer than an eeePC). One reason form factor matters, in my mind, is that it could make the devices “disappear.” That, and the difference between having a device on you (in your pocket) and carrying a bag with a device in it. Form factor was a big issue with my Newton MessagePad 130. As the OLPC XO showed, cost and power consumption are also important issues regarding screen size. I’d vote for a range of screens between 3.5 inch (iPhone) and 8.9 inch (eeePC 900) with a rather high resolution. A multitouch version of the XO’s screen could be a major contribution.

In terms of both audio and screen features, some consideration should be given to adaptive technologies. Most of us take for granted that “almost anyone” can hear and see. We usually don’t perceive major issues in the fact that “personal computing” typically focuses on visual and auditory stimuli. But if these devices truly are “for the rest of us,” they could help empower visually- or hearing-impaired individuals, who are often marginalized. This is especially relevant in the logic of humanitarianism.

HftRoU needs a much autonomy from a power source as possible. Both in terms of the number of hours devices can be operated without needing to be connected to a power source and in terms of flexibility in power sources. Power management is a major technological issue, with portable, handheld, and mobile devices. Engineers are hard at work, trying to find as many solutions to this issue as they can. This was, obviously, a major area of research for the OLPC. But I’m not even sure the solutions they have found are the only relevant ones for what I imagine HftRoU to be.

GPS could have interesting uses, but doesn’t seem very cost-effective. Other “wireless positioning systems” (à la Skyhook) might reprsent a more rational option. Still, I think positioning systems are one of the next big things. Not only for navigation or for location-based targeting. But for a set of “unintended uses” which are the hallmark of truly disruptive technology. I still remember an article (probably in the venerable Wired magazine) about the use of GPS/GIS for research into climate change. Such “unintended uses” are, in my mind, much closer to the constructionist ideal than the OLPC XO’s unified design can ever get.

Though a camera seems to be a given in any portable or mobile device (even the OLPC XO has one), I’m not yet that clear on how important it really is. Sure, people like taking pictures or filming things. Yes, pictures taken through cellphones have had a lasting impact on social and cultural events. But I still get the feeling that the main reason cameras are included on so many devices is for impulse buying, not as a feature to be used so frequently by all users. Also, standalone cameras probably have a rather high level of penetration already and it might be best not to duplicate this type of feature. But, of course, a camera could easily be a differentiating factor between two devices in the same category. I don’t think that cameras should be absent from HftRoU. I just think it’s possible to have “killer apps” without cameras. Again, I’m biased.

Apart from networking/connectivity uses, Bluetooth seems like a luxury. Sure, it can be neat. But I don’t feel it adds that much functionality to HftRoU. Yet again, I could be proven wrong. Especially if networking and other inter-device communication are combined. At some abstract level, there isn’t that much difference between exchanging data across a network and controlling a device with another device.

Yes, I do realize I pretty much described an iPod touch (or an iPhone without camera, Bluetooth, or cellphone fees). I’ve been lusting over an iPod touch since September and it does colour my approach. I sincerely think the iPod touch could serve as an inspiration for a new device type. But, again, I care very little about which company makes that device. I don’t even care about how open the operating system is.

As long as our minds are open.

I Want It All: The Ultimate Handheld Device?

In a way, this is a short version of a couple of posts I’ve been planning. RERO‘s better than keeping drafts.

So, what do I want in the ultimate handheld device? Basically, everything. More specifically, I’ve been thinking about the advantages of merging technologies.

At first, I was mostly thinking about “wireless” in general. Something which could bring together WiFi (802.11), WiMAX, and (3G) cellular networks. The idea being that you can get the advantages from all of these so that the device can be online pretty much all the time. It’s a pipedream, of course, but it’s a fun dream to have.

And then, the release of location services on the iPhone and iPod touch made me think about some kind of hybrid positioning system, using GPS, Google’s cellphone-based positioning, and Skyhook‘s Wi-Fi Positioning System (WPS).

A recent article in USA Today explains Skyhook’s strategy:

Jobs, iPhone have Skyhook pointed in right direction – USATODAY.com

And the Skyhook site itself has some interesting scenarios for WPS use in navigation, social networking, content management, location-specific marketing, gaming, and tracking. It seems rather clear to me that positioning systems in general have a rather bright future. I also don’t really see a reason for one positioning system to exclude the others (apart from technological and financial issues).

Positioning will be especially useful if it ever becomes really commonplace. Part network effect, part glocalization.

Of course, there are still several issues to solve. Including privacy and safety concerns. But a good system would make it possible for the user to control her/his positioning information (when and where the user’s coordinates are made available, and how precise they are allowed to be). Even without positioning systems, many of us have been using online mapping services (including Google Maps) to reveal some details about our movements. Typically, we’re fine with even perfect strangers knowing that we’ve been through a public space in the past yet we may only provide precise and up-to-date location details to people we trust. There’s no reason a positioning system on a handheld device should only work in one situation.

Now, I’m not saying that positioning is the “ultimate handheld device’s killer app.” But positioning is the kind of feature which opens up all sorts of possibilities.

And, actually, I’ve been thinking about GPS devices for quite a while. Unfortunately, most of them are either quite expensive or meant almost exclusively for car navigation or for outdoor activities. As a non-wealthy compulsive pedestrian who hasn’t been doing much outdoors in recent years, a dedicated GPS device never seemed that reasonable a purchase.

But as a semi-nomadic ethnographer, I often wished I had an easy way to record where I was. In fact, a positioning-enabled handheld device could be quite useful in ethnographic fieldwork. Several things could be made easier if we were able to geotag field material (including fieldnotes, still pictures, and audio recordings). And, of course, colleagues in archeology have been using GPS and GIS for quite a while.

Of course, any smartphone with a positioning system could help. Apple’s iPhone is one and we already know that smartphones compatible with Google’s Android will be able to have location-based functionalities. Given Google’s lead in terms of maps and cellphone-based positioning, those Android devices do sound rather close to the ultimate handheld device.
