Anyone who reads this blog often knows my disdain for touch-controls on mobile games. There are a few titles out there that are intuitive enough, like NBA Jam, Dark Meadow, and Horn, but past that, most games are just awkward to play. Thus, if a game supports it, I usually use some sort of controller, be it Bluetooth or USB. While that's practical enough at home, large controllers are too cumbersome for gaming on-the-go.
Ready for a mind-blowing example of what Android is capable of? You'd better be - Sensorcon, hoping for funding from Kickstarter, has thrown together a demonstration of Sensordrone, an accessory for your Android device that will be small enough to fit on your keychain and yet powerful enough to pack 13 different sensors under its hood, paving the road for hundreds of potential new apps.
In a nutshell, Sensordrone is an entire suite of sensors, useful for projects ranging from gas oxidization to color intensity measurement.
