[Blindmath] Tactile Displays?

[Roopakshi Pathania]

Hi Bert and all,

Yes, this is the kind of technology I am excited about. The cost of tactile displays for virtual images will surely be high, but the benefits are going to be huge.

Accademically, imagine being able to follow your coligues, or your professors, while in a lecture presentation, a paper discussion, , etc.
This would also help engineers, economists, financial analysts, and others working in the corporate sector.

Regards
