From the mailbag:
The Therapeutic Research Foundation (TRF), with input from the access technology team at the National Federation of the Blind Jernigan Institute, has created a survey on health, mobility, and navigation. TRF is inviting blind and low-vision participants to take the survey to help them create the next generation of navigational tools. The data gathered will be used specifically to do research and development, so please consider taking the time to complete the questionnaire and help them build a device that will serve your needs. Depending on your responses, the survey will take 5-15 minutes, and your impact will shape the future of the project.
You can take the survey at https://www.surveymonkey.com/s/XNZKWL8.
