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.
