Reach out and touch whatever screen you're reading this on. What if, instead of feeling the glass or plastic beneath your finger, you could experience the texture
of a brush, woodgrain, or even a stone? Well, Toshiba's working on just such a project, which operates on the basis of a film affixed to, say, a smartphone's touch panel -- electrical currents are sent through this layer, and your digits are shot up with the simulated sensation of touching those various surfaces. Senseg, the company behind this tech, has been around since 2008, but perhaps this recent prototype demo is a sign that things might actually start going places. It's not like there'll be a shortage of imaginative uses for such precise tactile feedback. Video after the break.
