yeah, you are right. It does seem logical, since they are using other senses so much more often.

This is only an interesting question raised during developing Blind Hero here at the University of Nevada, Reno. From the data we collected, we found blind users have better performance using haptic glove playing Guitar Hero. It was fun experience for sighted people playing Guitar Hero by staring at a black computer screen and purely relying on the sense of touch from the vibrating glove. This made us wonder do blind people truely have better sense of touch than us? More details can be found at this year's ACM SIGACCESS publication .
