Wii Remote
The Wii Remote also became a popular unit to hack for other applications. As it connected through standard Bluetooth interfaces, programmers were able to reverse engineer the communications protocol and develop application programming interfaces for the Wii Remote for other operating systems, and subsequently games and applications that used the Wii Remote on alternate platforms. Further hacks at the hardware level, typically taking apart the Wii Remote and Sensor Bar and reconfiguring its components in other configurations, led to other applications such as remote hand and finger tracking, digital whiteboards, and head tracking for virtual reality headsets.
