Holon Institute of Technology Abstract: A mobile, Head-Mounted Low Vision Aid is critically needed for the vision impaired. We will report on a research effort of a Low Vision Goggle (LVG) based on a unique Image Transceiver Device (ITD), combining both functions of imaging and display in a single chip. The LVG's function is to capture the ambient scene, generate an enhanced imagery of the Region of Interest (ROI) and project the enhanced imagery onto the healthy part of the retina. An incorporated Eye Tracker is used in order to determine the ROI as well as in directing the Imagery to the preferred region of the patient's retina (PRL). Another important function of the LVG is in providing a direct, See-through capability. The unique ITD device allows a compact design of the Low Vision Goggle (LVG) with its present design based on a CMOS- LCOS micro-display.
The device design effort includes the CMOS chip as well as the FPGA system controller. In addition to the ITD Chip development, the research effort also covers the optical design of the LVG as well as the development of a low vision model and studies of image enhancement algorithms for the visually impaired. A brief description of these studies will be presented. Hosts: Prof. Alexander Sawchuk and Prof. Keith Jenkins
