In last Cognitive Psychology class, the professor told us why it is dangerous to walk using smartphone. I’m interested in UI, so I asked him how to reduce dangerousness.
One of the reason is: Because character size is generally smaller than legacy phone, users have to concentrate on the display.
I asked him suddenly, so he didn’t find out so many good way, but he gave me an idea that times of operation should be reduced. Then users have to concentrate on less.
He also gave me another idea: The machine analyze the movement of user’s eyes, and contents scroll automatically. There is already eye camera, so we can realize it if we don’t care heaviness of the machine, but it is the problem how to make it generally acceptable…
