The Finger-Joint Gesture Wearable Keypad

A wearable, fragmentised, idiomatic, generic and mobile keypad concept, making use of well-established metaphors, is suggested for entering digits and characters. The “Finger-Joint Gesture Wearable Keypad” terminal utilises the inside of the phalanges of the fingers as a wearable telephone keypad. Negligible training time is required. By employing the thumb as an operator, depressing the insides of the finger’s phalanges, the familiar keypad digits and characters are created. By generating finger gestures by letting the operator depress the nail of a finger, different telephone functions are accomplished. The concept is generic and several other functions can easily be generated. The context as a necessary prerequisite for inducing restrictions is discussed as a viable way for creating support for suggesting new design approaches.
