So has everyone heard about the Shine already?http://www.technationnews.com/2012/11/15/misfit-shine-activity-tracker-beautiful-design-weird-name/
Seems like a neat device, my style than substance really, but the wireless sync seems intriguing. Does anyone care to fathom a guess with me as to how it works?
Considering it would need to work with an iOS5 device it could work via Bluetooth and Wifi but the video says they use a proprietary communication technology. I thought it first it could be something to the Electric Imp which utilizes a light sensor and synchronized flashes as a pseudo-1-wire interface but the video seems to point at something that is bi-directional (it knew the location of the device on the screen). Even ultra-sonic sounds in the same vein could not do that.
Unless that was a total fabrication made just for the video how can it determine the position of such a device (encased in metal) with just the few sensors an iPhone would have. Perhaps it can read the current pixel it is over and send that back to the iPhone, but how, via Bluetooth? Considering the size of this thing and that it's battery is supposed to last 6 months that seems highly unlikely.
