ABSTRACT:
A data entry device, including a plurality of sensing devices worn on a user's fingers, and a flat light-weight keypad for transmitting signals indicative of data entry keyboard functions to a computer or other data entry device. The sensing devices include sensors are used to detect unique codes appearing on the keys of the keypad or to detect a signal, such as a radar signal, generated by the signal generating device mounted to the keypad. Alternatively, sensing devices may be mounted to the keypad to determine the location of a user's finger upon selection of a keypad key. Pressure sensitive switches, one associated with each finger contain resistive elements and optionally sound generating means and are electrically connected to the sensors so that when the switches are pressed they activate a respective sensor and also provide a resistive force and sound comparable to keys of a conventional keyboard. Alternatively, a flat fully functional keyboard or touchscreen, which does not provide the user with significant tactile or auditory indication of a user's selection of a key, can be used and pressure sensitive switches containing resistive elements and optionally sound generating means are mounted to the user's fingers.
