Abstract:
An m-by-n switch array comprises a frame, switches that anchor around the frame, and threads that connect the switches to their opposing sides of the frame. Applying pressure on a thread pulls the switch, connected to that thread, to its ON state and releasing pressure on the thread lets the switch, connected to that thread, bounces back to its natural OFF state. Applying pressure on an intersection of two threads pulls the two switches, that connected to the two intersected threads, to their ON states while releasing pressure lets those two switches bounce back to their natural OFF states. The position of the intersection, where pressure is applied, can be determined by checking the ON/OFF states of all the switches. Keys can be placed on the thread intersections to emulate devices such as keypads, calculators, remote controls, keyboards, and other key input devices.
