Patent Images
1. A user interface, comprising:
- a liquid crystal display divided into a plurality of regions;
a microcontroller operatively coupleable to a host controller, the microcontroller driving the liquid crystal display according to signals received from the host controller so as to display text or images on each of the plurality of regions of the liquid crystal display;
a plurality of transparent keys, each of the keys overlying a corresponding one of the regions of the liquid crystal display, each of the key defining a separate tactilely-distinguishable touch area, and each of the keys being independently cantileverable;
a plurality of mechanical switch elements disposed proximal to the regions of the liquid crystal display, each of the switch elements being engageable by one of the keys and providing positive tactile and aural feedback when the key is depressed and released; and
wherein the microcontroller detects actuation of the switch elements and provides an indication to the host controller in response thereto.

Abstract
Described is a user interface particularly suited for use in a home automation system. This interface combines advantages of a conventional touch screen (such as ease of use and accurate "key" placement) with the advantages of a conventional mechanical keypad (such as reduced cost and tactile feedback). The interface is well suited for use on any wallspace and may be easily reconfigured as necessary to support a host of system functions. The interface utilizes a backlit LCD separated into separate display sections, each having a durable, scratch resistant lens. Cantilevered switches associated with each display are used detect a user'"'"'s selection of a displayed option.
