Studies and Development Effort of a Low Vision Goggle:
Recent Progress on Optical Design, Device Design, and Image Enhancement; and, Recent Improvements in Iris RecognitionAbstractA 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 recent 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. Our recent progress on iris recognition will also be described.Host: B. Keith Jenkins, x04149, jenkins@sipi.usc.edu
