Evaluation of force display touch pad for the visually impaired

This study aims to develop a device to support the use of PCs by the elderly and visually impaired. The force display touch pad is a pointing device that presents the position of a window frame or buttons on a PC screen to the user using a force feedback function. We consider this device as a mockup, therefore we will perform demonstrations of the device, and then modify it according to surveyed user needs. Of the many users of PCs, visually impaired individuals typically make use of a screen reader, which is software that translates information on the computer screen into auditory information. In this paper, we evaluate the operability and accessibility of the force display touch pad with added auditory output.
