In this report we identify the most promising directions for research on the mobility problems of visually impaired and blind people. We show that information is not generally available on the number of people who might benefit from electronic travel aids. Although we have made some guesses about the prevalence of visual impairment and blindness in the United States, we believe them to be underestimates of the true rates. Better information is needed about this population and should be collected with certain variables in mind: age, onset, degree of impairment, and certain social factors such as income level. Information is also not available on the use of electronic travel aids. More extensive follow-up studies are needed to determine the usefulness and success of particular devices.
