The WearBoy: a platform for low-cost public wearable devices

We introduce the WearBoy-a wearable, modified Nintendo GameBoy-as a platform for exploring public wearable devices. We have minimized the size of a Color GameBoy circuit board to enable users to comfortably wear it, making the device not much larger than the actual screen. Technical properties of the WearBoy are discussed, along with two applications using the platform.
