This is a remote control system that uses a touch screen to display various control screens, each showing a fixed number of function buttons. A physical cover extends over the touch screen, allowing users to feel and select these buttons. When a button is selected, the system wirelessly sends a command to control another device, such as scrolling menus on a TV or selecting multimedia content.
