In my research to better understand visual impairment in the real world, a partner and I applied a visually impairing cream to some sunglasses and attempted to walk through public areas. The biggest challenged going through these areas was obviously finding differences in surface are for walking. We found that contrast in color between different levels in in pathways was the most effective in traveling effectively.
We also had to be able to see close up with door handles and an ATM machine. We found that signage with larger type and red lettering was easier to comprehend.
Natural light was also much easier to see and differ from artificial light, but differing between a mix of both was another huge challenge. This was literally an eye opening challenge for both my partner and I. It made me appreciate the visual capability I do have and that texture and grip underfoot help so much more then you would ever think.
