project description
An input device is a hardware device which is used to send input data to a computer or which is used to control and interact with a computer system. Contemporary input mechanisms can be categorized by the input medium: Keyboards and mice are hand-operated, Siri and Alexa are voice-based, etc. The objective of this project was to come up with a head movement based input system that improves upon earlier such systems. Input entry based on head movements may help people with disabilities to interact with computers more easily. The system developed provides the flexibility to capture rigid and non- rigid motions. Unlike prior work, the organization of alphabet symbols in our design is based on the frequency of the characters in the English dictionary. We conducted experiments on our system and compared it to previous head movement systems.
