Abstract
A keyboard is a commonly used input device that facilitates human computer interaction by allowing the user to enter commands by physically pressing units called keys. The keys can be physically embedded on the system or can be a logical concept (such as on touchscreens [x]). In this paper we discuss the aspects of a novel keyboard, its circuit, its working model and efficiency. This keyboard uses the principle of infra red emission and reception which generates an active low signal on placing an obstruction between the emitter and receiver.
