i-gesture thoughts

Multi-touch, tactile and communication….how can you communicate with touch/tactile with technology?

What are the semantics of touch/gesture? (Build on tactex work….what can i-gesture add?... motion, position, contact, velocity.)

previous work with tactex measured pressure and analyzed shape: the tactex pad gave pressure data along with image.

Gesture was analyzed using image processing algorithms.

The i-gesture pad doesn’t measure pressure; it measures contact and motion. This data-set is quantitatively and qualitatively different than the tactex pad:

- it cant detect pressure but it can detect the slightest touching, something the tactex can not; you need to apply some force on the surface. So the i-gesture is suitable for more subtle and gentle interactions.

- Gives data on motion and velocity of individual fingers; more low-level than tactex...i-gesture is more suitable for interactions that are gesture and motion based….can also be used to record and measure gestures for research.

- I-gesture gives accurate positioning data along with motion data….meaning you can design synchronous interactions between two or more people….communication?

Touch Semantics:
- previous work based on Laban taxonomy.
- Classification and parameters based on pressure and shape (blobs)
- I-gesture can give motion, position, and velocity…can these parameters either validate OR expand on the touch semantic research?

Touch and Communication:

- Since multi-touch first mainstream application is on a communication device (iphone), what spaces for communication does multi-touch open?

concept:
investigate interactions that occur when two people (remote or co-located) touch each other/touch the same spot.....synchronous touch and gesture research for communication

1) interactive wall: two touch-walls located in two separate locations, once participants touch the same spot......
2) fabric-touch pads
3) i-phone envisionments
