Technologies of Touch

From a recent TED:  A look at the technology of Touch.  We did a number of experiments with touch interaction with products.  The attempt was to include other senses in retail interaction.  Smell, Sound and Touch were experimented with as examples beyond the usual kind of interactions.   This is beyond the use of a touch screen, but the use of touch for deeper and more precise engagement beyond just indicating a place on a screen. Its good to see that others are still carrying this work further.
