Abstract
In this paper, we implement a virtual keyboard using infrared distance sensor. A virtual keyboard allows a user to enter characters by selecting keyboard layouts with sensing areas. By projecting infrared light on any flat surface and detection devices we can sense the user's input characters. Unlike a conventional physical keyboard, the virtual keyboard provides convenience in terms of mobility, portability, and space savings.
