Touchless UI – Solving Problems or Creating Them?
On my way through the San Francisco International Airport last month, I stopped at one of the new automatic water dispensers to fill my water bottle. I set my bottle down below the spigot and waited for the water to come out, as is common with most of the automatic dispensers currently on the market. However, when nothing happened, I began waving my hand around the machine in an attempt to find the sensor, while simultaneously looking around to see if anyone noticed how silly I looked.
