In the past few years, we have seen plenty of cool VR controllers with all kinds of bells and whistles. The etee is a button-free controller with a simple design that lets you play by moving your fingers. It can register touch, proximity, pressure, and gesture.
etee senses slight movements of your finger to bring your hands into VR worlds. The SteamVR version comes with 6DOF and embedded haptic feedback. The battery lasts up to 6 hours.
