I’ve been thinking for some time now that the smartphone has achieved a kind of singularity, becoming a black hole that sucks all portable electronics into itself. PDAs – absorbed. Music players – consumed. Handset GPSes – eaten. Travel-alarm clocks, not to mention ordinary watches – subsumed. Calculators – history. E-readers under serious pressure, and surviving only because e-paper displays have lower battery drain and are a bit larger. Compasses – munched. Pocket flashlights – crunched. Fobs for keyless locks – being scarfed down as we speak, though not gone yet.
This raises an interesting question: what else is natural prey for the smartphones of the future? Given my software interests, one low-hanging fruit that seems obvious to me is marine AIS receivers. If the frequency of any of the RF receiver stages in a phone were tunable, writing an app that would pull AIS data out of the air wouldn’t be very difficult. I’ve written a lot of the required code myself, and I know where to find most of the rest.
But in an entertaining inversion, one device of the future actually works on smartphones now. Because I thought it would be funny, I searched for “tricorder” in the Android market. For those of you who have been living in a hole since 1965, a tricorder is a fictional gadget from the Star Trek universe, an all-purpose sensor package carried by planetary survey parties. I expected a geek joke, a fancy mock-up with mildly impressive visuals and no actual function. I was utterly gobsmacked to discover instead that I had an arguably real tricorder in my hand.
