Project Title: An Improved Low-Cost Nose Tracking Cursor Control With Some New Features

University : Khulna University of Engineering and Technology

Idea: Persons with tetraplegia, suffering from traumatic brain injury, cerebral palsy, neurological injury or stroke, are very difficult to use personal computers’ standard input interface, such as the keyboard and the mouse, during their rehabilitation and everyday life activities. Therefore, it is highly desired to develop Assistive Technologies (ATs) for persons with tetraplegia. In our work, Human Computer Interface(HCI) is implemented with digital image processing and new approach to control personal computers with high efficiency. The main three features of this interface are nose tracking cursor control, auto brightness control and face controlled display off. In nose tracking system, anyone can control cursor by moving nose and changing mouth status. Its performance is better than camera mouse and any other comparative systems. Auto brightness control system change the display brightness automatically to make the display more comfortable for eyes. And face controlled display off, turn off the display when no one is using it which saves around 20W of power. All these features make the computer friendlier for disable person and improve its efficiency.
