The Americans with Disabilities Act, championed by the late President Bush, has removed barriers and improved the lives of people of all abilities. For instance, everyone can appreciate the utility of levered door handles that allow one to open by simply pushing with their gluteus maximus while carrying a young child and bag of groceries.

Still, some of the measures to improve access for some may harm others. For instance, truncated domes, which serve as a tactical interface between sidewalk and road or parking lot and provide are great for the visually impaired, but can be a tripping hazard in slippery conditions, for those wearing high-heels or rollerblading.

The above interview with IntelligentMaterials sheds light on an interesting invention that could create virtual truncated domes and better way-finding for everyone. In addition, their smart paint could be a good a great tool for helping autonomous vehicles stay on course.
