Abstract

An input device includes a plurality of keys, each having an exclusive input key code corresponding to an illumination unit, a notification unit and a detection unit. An electronic device includes an execution unit and a first comparison unit. The execution unit generates a preset key code and an illumination command. The corresponding illumination unit emits light according to the illumination command. The detection unit detects whether one of the keys is activated, if a key is activated, generate an input key code. The comparison unit compares the preset key code and the input key code. If the two codes are the same, the comparison unit generates a stop signal. The illumination unit stops shinning according to the stop signal. If the two codes are different, the comparison unit generates a notification. The notification unit issues a notification accordingly.

Claims

1. An input device connected with an electronic device, the electronic device comprises an execution unit and a communication unit, the execution unit generates a preset key code and an illumination command, the communication unit sends the preset key code and the illumination command to the input device, the input device comprising:

a plurality of keys each having an exclusive input key code; and

a plurality of illumination units each corresponding to one key, the illumination unit corresponding to the key which input key code is the same with the preset key code adapted to emit light in response to the illumination command so as to prompt the user to press the key which input key code is the same with the preset key code.

2. The input device of claim 1, wherein the key is a transparent key or a translucent key.

3. The input device of claim 1, wherein the input device further comprise a plurality of detection units each corresponding to one key, the electronic device further comprises a first comparison unit, the execution unit sends the preset key code to the first comparison unit, the detection unit adapted to detect any of the keys being deactivated, if a key is activated the detection unit sends an input key code to the first comparison unit through the communication unit, the first comparison unit compares the preset key code and the input key code.

4. The input device of claim 3, wherein if the input key code is the same with the preset key code, the right key is activated, the first comparison unit generates a stop signal, the corresponding illumination unit stops emitting light according to the stop signal.

5. The input device of claim 3, wherein the input device further comprises a plurality of notification units each corresponding to one key, if the input key code is not the same with the preset key code, the erroneous key is activated, the first comparison unit generates an error notification, the notification unit issues a notification according to the error notification.

6. The input device of claim 5, wherein the notification unit is a vibration motor.

7. The input device of claim 5, wherein the electronic device further comprising a determination unit, the determination unit determines whether an input key code is received, if an input key code is received, the determination unit transmits the input key code to the first comparison unit.

8. The input device of claim 7, wherein the electronic device further comprising a timing unit and a second comparison unit, if an input key code is not received, the timing unit measures the non-operating duration according to the timing signal, the second comparison unit comprises a predetermined non-operating duration value, the second comparison unit compares whether the non-operating time is at least the predetermined non-operating duration.

9. The input device of claim 8, wherein if the non-operating time is at least the predetermined non-operating duration, the erroneous key is activated, the second comparison unit generates an error notification, the notification unit issues a notification according to the error notification.

10. The input device of claim 8, wherein the non-operating duration is equal to the length of time required for the execution unit to generate a preset key code.

11. An input device connected with an electronic device, the electronic device comprises an execution unit and a first comparison unit, the execution unit generates a preset key code, the input device comprising:

a plurality of keys;
