Human Computer Interactions has been a matter of great consideration for engineers, researchers, designers and industrial experts from decades. Every device, be it a smart phone, personal computer, ATM machines, etc. comes with a user interface for a layman to understand and to use the device. With the advancing technology, different modes of user interface are proposed. The most common of all is a touch interface. Most of the interactive devices now come with a touch interface. This paper presents an approach to provide a similar external touch interface for laptops and computers that further can modify for much smaller devices such as mobile phones.
