It’s too perfect. I can’t belive it that it has so many cutting edge functions as the company says.

This is a demo of multi-point interface.


Multi-touch means that you use multiple fingers


Multi-point means that you use multiple mice :-)

Paper Computing

Jaehwan Kiim at Inha University has developed a technology that makes a sheet of paper literally change its shape.
We have come across that cellulose based paper can produce a bending displacement in the presence of electric field. This smart cellulose is termed Electro-Active Paper (EAPap). It can produce a large bending displacement with low actuation voltage and low power consumption.

In addition, researchers at MIT Media Lab has presented pulp-based computing. They embedded various electro-active materials into paper through papermaking process. They implemented bending sensors and kinetic (active) paper with the developed technology.


Combining the two with paper-like displays such as e-paper and OLED display, possible applications might be:

Napkin PC



Bendable computers

[CHI2009] Double-side Multi-touch Input for Mobile Devices

This new double-sided multi-touch mobile interaction model enables intuitive finger gestures for manipulating 3D objects and user interfaces on a 2D screen. Although multi-touch input enables scrolling and the zooming of a document, its manipulation is constrained to two dimensions over the horizontal or vertical planes of a mobile device’s 2D touch screen. By adding touch inputs from the device’s back side, the degree of freedom for manipulation can be extended to a pseudo three dimensions.

 

Grabbing an object. Dragging an object (x and y axes) by simultaneously moving fingers on both sides of the device.

Pushing up/down on an object by touching on the object from back/front side of the device. Flipping an object by grabbing and sliding two fingers in opposite directions.

Stretching an object by grabbing it with two pairs of fingers and sliding those two in different directions.

Synaptics brings out 10 finger capacitive multi-touch screen

Synaptics announced new ClearPad 3000 Series capacitive multi-touch solution.



Specifications
- Number of sensing channels: 48
- Display size: up to 8"
- Accuracy: ±1 mm
- Thickness: 0.3 mm
- Power consumption: 5 mA in active mode, 12 uA in sleep mode

Via Multitouch + NUI and Engadget

[Note]
Richard Monson-Haefel at Multitouch + NUI suggests a good empirical rule that is useful to identify required sensing specifications of multi-touch screens or surfaces. He calls it "half-diagonal" and I rewrite his rule in the form of equation as shown below:

Maximum number of fingers to detect = Display's diagonal size (in inch) / 2

For example, if you consider an 8" display, the equation tells that four finger touch is enough for your application.

And F. Wang and X. Ren also reported several statistics that are helpful to design multi-touch applications.
