Fingual - Finger-Language interface device

This finger language interface device is designed by a group from the Osaka and Shinshu University. This interface helps in entering text on the monitor via one's finger movement.

The user has to wear a pair of special gloves which has permanent magnetic sensors or photoreceptors embedded at its finger tips. With every movement of the finger the magnetic field gets shifted. That change is then noticed by the sensors and is translated into a text format. The magnetic field for each finger shape is used as a data set, and by capturing this data for each user, text recognition can be done easily.

This technique is particularly helpful for people using sign language. It will also be beneficial for people in e-mailing or messaging where texts can be entered by finger language instead of typing. Currently this technique is in use for text output only, but scientists are aiming at capturing the sound output of every finger movement, which could be used in case of musical instruments.
