Abstract

A keyboard adapted for use as a data entry device in a data- or word-processing system, having keys which are each provided with respective active transducer devices, such as piezo-electric transducers, which can transmit a tactile feedback signal to the fingers of the operator. The transducers are activated either automatically whenever a respective key is pressed, or under the control of a software program which detects whether the keys have been actuated in an intended sequence, and then activates the transducers, or activates the transducers in advance to provide prompts to the operator to signal keys which are intended to be actuated. <IMAGE>

Description

SPECIFICATION Data input device with tactile feedback This invention relates to keyboards such as those used with computers for data input, and on musical instruments, and to methods of teaching keyboard skills on such devices.

With some types of computer keyboards in particular, it can be difficult for the operator to be certain whether a particular entered character has been properly received by the system.

This is particularly the case when the keyboard is designed to be "soft" to the touch or when it is constructed in the form of a flat printed circuit board covered with a plastic surface.

According to a first aspect of the present invention, there is provided a keyboard adapted for use as a data entry device for a computer or like data or word processing device, (hereinafter referred to as a computer) in which at least some of the keys are each provided with a transducer adapted to transmit a tactile feedback signal to the fingers of the operator.

The invention also extends to a method of teaching keyboard skills, comprising programming a computer device having a keyboard for data input and means for feeding back tactile signals to the operator, in such a way that a cueing signal is transmitted to a key which it is intended should be operated or a confirming signal is sent to the operator when a correct response is given to a prompt from the program.

In one possible embodiment of the invention, hardware or software interface means are provided to transmit an activating signal to a given transducer of the keyboard, whenever the corresponding key is properly actuated by the operator. In an alternative embodiment of the invention, software means are provided to transmit an actuating signal to a given transducer only when the corresponding key is validly activated in accordance with an instruction or set of exercises (for example) presented to the operator by the computer system.

One embodiment of the invention comprises a flat printed circuit keyboard having an overlay printed with a pattern corresponding to the key positions, which comprise sensors incorporated in the printed circuit. The arrangement is such that the overlay can flex slightly when it is pressed, so that the underlying sensor is actuated. A piezo-electric transducer is positioned between the sensor and the overlay and is arranged to be actuated by a feedback signal from the computer to the keyboard. The feedback signal is produced by a software interface which can be programmed so that (for example) it transmits a signal to the appropriate keyboard transducer whenever the corresponding sensor is actuated.Alternatively the signal may be transmitted only when a program routine confirms that the sensor which has been actuated constitutes a correct operator response to the program, or it may be transmitted to a key before the operator is expected to actuate it as a cueing signal.

1. A keyboard adapted for use as a data entry device in a data-or word-processing system, having at least some keys which are provided with respective active transducer devices adapted to transmit a tactile feedback signal to the fingers of the operator.

2. A keyboard according tod claim 1 in which the transducers are piezo-electric.

3. A keyboard according to claim 1 or claim 2 including circuit means adapted to transmit an activating signal to the transducer of each key, whenever that key is actuated by the operator.

4. A keyboard according to claim 1 or claim 2 in combination with a data processing device programmed to provide an activating signal for the transducer of each key, whenever that key is actuated by the operator.

5. A keyboard according to claim 1 or claim 2 in combination with a data processing device programmed to provide an activating signal for the transducer of each key, only when that key is correctly actuated by the operator in accordance with a sequence set by the program.

6. A keyboard according to claim 1 or claim 2 in combination with a data processing device programmed to provide activating signals for the transducers of a series of keys in accordance with a sequence set by the program, so as to promt the operator to actuate the keys in the said sequence.

7. A keyboard substantially as herein described.

8. A data-or word-processing system having a keyboard substantially as herein de scribe.
