Mime

Mime is a compact, low-power 3D sensor for short-range gestural control of small display devices. The sensor's performance is based on a novel signal processing pipeline that combines low-power time-of-flight (TOF) sensing for 3D hand-motion tracking with RGB image-based computer vision algorithms for finer gestural control. Mime is an addition to a growing number of input devices developed around the engineering design philosophy of sacrificing generality for battery-friendly and accurate performance to retain the portability advantages of our smart devices. We demonstrate the utility of Mime for Head Mounted Display control and smart phones with a variety of application scenarios, including 3D spatial input using close range gestures, gaming, on-the-move interaction, and operation in cluttered environments and in broad daylight conditions.
