Touch panel of the tactile feedback of new proposals emerge (1)

For touch panel uses, and the original completely different haptic feedback technology proposals to increase.

A new way, or combined with other features of the technology is already available. Toshiba information systems to take advantage of weak electric field variation for various tactile technology, manufacture of the corresponding product.

Prior to that of haptic feedback technology, generally is used by small motor and piezoelectric vibration occurring such as, using the method of electric field variation is rare.

　　

Use of electric field variation method has the advantage in addition to being able to show more tactile, with no mechanical parts, thus no vibration sound, not easily damaged.

Do not select to prompt the sense of touch is the one place. In the electronics of the back side, as well as surface and so original technology elusive places can also be used. In addition, you are free to control provides the touch area. For example, only when the user touches the screen display of the button, the tactile feedback.

In order to promote the kind of tactile available, Toshiba information systems (GIS) in the "13th embedded system development technology exhibition (ESEC)" exposed "iPodtouch" and the introduction of the touchpad of samples (Figure 1).

Using iPodtouch provides horizontal sliding finger touch button allows the user to feel part of the button is located on a different touch. The touchpad, the personal computer screen shows the surface of the "brush", "rough surface" and "uneven materials", etc, when you place the cursor in a different image above, fingertip access to the touch (Figure 1 (b).

　　

The key is thin-film materials

Develop the use of electric field variation technique is Finland's venture company Senseg Oy Note 1).

The company provides control special films and electric field variation of modules, control software, as well as a variety of haptic database (Figure 2).
