Vision Correcting Display

Current estimates are that myopia (nearsightedness) affects almost one third of the people in the world.  Presbyopia, farsightedness caused by loss of elasticity of the lens of the eye, affects about half the population by around age 50.  As an innovative assistive technology, the vision correcting display can provide an image which will be seen in sharp focus by a viewer without the use of eyeglasses or contact lenses.  The concept is that the text or image on the display is modified according to the measured vision problem of the viewer so that the transformed image will appear in sharp focus by the viewer.  This could impact computer monitors, laptops, tablets, and mobile phones.

Assistive Technology for Cursor Control

The mouse has become a standard input device for computers. But some people cannot comfortably use a physical mouse, and unfortunately, there are few viable alternatives. Difficulties in using a mouse can be associated with impaired sensation from conditions such as neuropathy (nerve damage), spinal cord and/or head injury, Type II diabetes, and other illnesses. This project aims to help those with impaired sensation by developing a computer-vision based input system with a camera as its input device.  In particular, this project is concerned with assistive technology that enables users with fine motor control difficulties to navigate, select, point, and click without physically manipulating a mouse. The idea is to use a camera to capture the user’s hand movements. As for the general structure, the system consists of three modules of detection, tracking, and response.
