kai lets you control any digital device by tracking your hand and finger gestures

human augmentation start-up vicara has created kai, a smart wrist band that lets you interact with digital devices by tracking your hand and finger gestures. aimed at increasing productivity drastically, kai features gesture-based computer interaction technology that is compatible with any bluetooth-enabled device including laptops, mobile phones, televisions, VR/ARand even drones.

vicara‘s minimal, portable and highly effective device uses an inbuilt finger/hand tracking technology instead of an external camera, freeing users from the need to keep their arms visible and under certain light conditions required for camera recognition. once connected, kai can be used for presentations as a pointer or to switch slides, draw and zoom in/out, as well as for switching between channels and adjusting the volume of your TV. additionally, the device can be used as a standalone controller in VR, gaming and drones, while it is compatible with all applications in mac, windows and linux laptops.

kai comes with its own special dev kits to help users integrate the device with other projects, including kai SDK which allows one to create gesture profiles for desktop software with API deep level integration. the device features includes a battery that lasts up to eight hours and users can choose among four colors: black, white, blue and red.
