This app emulates the HandScape device. Its main purpose is to aid HandScape-SDK developers who do not have access to (or high enough quantity of) a physical device. The emulator runs on any BLE-capable iOS device (iPhone 4S or later, iPad Mini retina, iPod-touch 5th gen, etc.)
The emulator is used in conjunction with other HandScape-enabled apps, which also work with the HandScape device.
Without a HandScapeSDK-enabled app, this emulator does not do anything particularly interesting.
