Haptics mouse for visually impaired

The research presented draws from the disciplines of electronics, mechanical engineering, biological sciences and aesthetics to create a handheld tactile mouse which can be used to aid data perception for visually impaired individuals. Visual information is presented to the user by means of small tactile array housed in a modified computer mouse. Varying frequencies of vibrations can represent a number of onscreen environmental changes, such as changes in colour, light intensity or the numerical values. The device is designed to operate either as an assisting tool which operates in conjunction with other interfacing aids, or as a stand alone system with a reduced function set.
