Abstract

The invention described herein represents a significant advancement in systems that enable a user to control systems and input data into a very wide range of systems. User interface devices that comprise an array of input devices such as buttons on a remote control, keys on a computer keyboard, touch screens, and a computer mouse. Such devices comprise an array of contacts that can be used to capture a user'"'"'s inputs and communicate them wirelessly using passive RFID apparatuses and processes. Contacts can be positioned in physical proximity to graphics or alphanumeric characters and this proximity can be stored in memory such that a user altering a specific contact status represents specific data to a controlled system or memory. Also, the sequence or change or direction of changes in contacts can be used to control systems or processes in predetermined ways. Remote controls, computer keyboards, a computer mouse, touch screens and pads created with the present contact array invention need not use complex circuits and do not require batteries to operate wirelessly.
