Piezoresistive sensors and methods

摘要: BACKGROUND0004 Human-machine interfaces provide ways to give commands to control computing systems or other program mable systems, for example robotic systems. However, cur rent human-machine interface technologies face certain limi tations when in use. For example, a touch sensing device, eg, the Microsoft SurfaceTM tablet, requires the users hand to be occupied. Optical sensing devices, eg, the Celluon Magic CubeTM and the Xbox KinectTM have a built-in optical sensor to capture finger and/or body movements, but these devices still have a limited space for a user to send commands to the machine. As another example, the Voice control in Smart phones, eg, Apple iPhone R5, is also limited by its accuracy, time delay, and a singular method of interaction. 0005 Challenges associated with the development of human-machine interaction interfaces include the limitations of traditional interactions …
