The Tap device uses sensors to detect the gestures users make and identify what they represent using complex algorithms. The Tap SDKs allow developers' applications to tap (no pun intended) into this technology and respond to those gestures. SDKs are available for iOS and Android, as well as a Unity plugin. All are available on Github and open sourced under the Apache 2.0 license.
The Tap Strap, which sells for $179, connects to most Bluetooth enabled devices. According to its maker, "Tap promises a future where a device doesn’t command our attention, it enables it."
Currently, a number of apps are available for Tap, including a learning system called Tap Learning, as well as two games, TapTapbunny and TapChase. Tap believes its device has a wide range of use cases, from gaming to augmented and virtual reality, and says that it has received interest from a number of third parties, including game developers and enterprise developers. By opening its technology up to outside developers, it clearly hopes to accelerate the growth of its app ecosystem.
