SO...what do all those papers and research on skin stretch mean for us?

Skin stretch seems to provide adequate response in humans, and with some thought, humans seem to be able to distinguish basic skin stretch patterns (up, down, left, right), but distinguishing more complicated patterns seems to be more difficult, as evidenced by Li and I from our initial tests.

What if time is necessary? Can we combine both vibration and skin stretch to provide information? For example, have something vibrate

Skin stretch vs. Vibration skin stretch you can vary the direction, the force, the velocity at which it is applied, the size of the tactor, vibration- you can vary the frequency, the size of the area,

It appears that vibration is an on/off mechanism?there is not much variation in its effects and it would be difficult for people to distinguish different types of vibrations. How do you change the "magnitude" of vibration? Vary the frequency, vary the time, vary the closeness to the skin?

So is it possible then for skin stretch to provide a wider variety of information transfer? Would it be too much information?

I question the ability of subjects to discern skin stretch direction while multitasking, and if they are wearing a device.

Concerns for slipping with tangential force motion

So now we have to think about how to differentiate tangential motion
