Relatively simple and inexpensive finger operated control device including piezoelectric sensors for gesture input, and method thereof

A method of operating a computing device, comprising:

• receiving signals from at least six electrodes of piezoelectric sensors coupled to at least one finger portion having an elastic polymer wall with continuous piezoelectric properties throughout the finger portion that covers at least 30% of a surface area of skin around a distal phalanx of a finger, the electrodes being disposed opposing each other on both sides of the elastic polymer wall and covered by a protective layer, wherein each opposing pair of the electrodes and a portion of the elastic polymer wall therebetween form a separate one of the piezoelectric sensors to directly detect a pressure acting on the separate one of the piezoelectric sensors orthogonal to a surface of the separate one of the piezoelectric sensors and orthogonal to the surface area of the skin;
• translating the signals into a relative or absolute movement within a user interface of the computing device, wherein the computing device is one of:
• a watch, computer operated glasses and an eye-tracking computing device, wherein the elastic polymer wall is shared by the at least six electrodes, and
• wherein the electrodes are positioned on an underside of the finger portion.
