Abstract

A detection device includes an input unit configured to receive an operation of a user, and a sensor provided in the input unit and configured to detect biological information of the user when the user operates the input unit.

Claims (31)

1. A detection device comprising:

an input device including an input device member and configured to receive an operation of a user, wherein the input device member includes a first input device member and a second input device member,

wherein the input device includes a sensor including a first sensor and a second sensor and configured to detect biological information of the user when the user operates the input device,

wherein the input device includes a light source unit including a first light source unit and a second light source unit,

wherein, in the input device, the first sensor is provided between the first input device member and the first light source unit,

wherein, in the input device, the second sensor is provided between the second input device member and the second light source unit,

wherein the first sensor and the second sensor include a plurality of optical sensors,

wherein the plurality of optical sensors of the first sensor include a first optical sensor and a second optical sensor exhibiting a sensitivity for different wavelength regions,

wherein the first optical sensor exhibits a first optical sensor sensitivity in a visible light wavelength region, and wherein the second optical sensor exhibits a second optical sensor sensitivity in a red wavelength region to an infrared wavelength region.

2. The detection device according to claim 1 , further comprising a controller configured to determine whether a predetermined function is executed based on the acquired biological information of the user.

3. The detection device according to claim 2 , wherein when the user inputs, to the input device, an operation of requesting execution of the predetermined function, the controller acquires, from the sensor, the biological information of the user in the operation of requesting the execution of the predetermined function, and determines whether the predetermined function is executed based on the acquired biological information of the user.

4. The detection device according to claim 2 , wherein

when the controller determines that the predetermined function is executed, the controller executes the operation assigned to the input device operated by the user in the detection of the biological information.

5. The detection device according to claim 1 , wherein the sensor is provided in at least one of a keyboard and a mouse as the input device.

6. The detection device according to claim 1 , wherein the first sensor is configured to detect a fingerprint of the user and the second sensor configured to detect a blood vessel pattern of the user.

7. The detection device according to claim 6 , wherein the first sensor includes a semiconductor containing amorphous silicon, and the second sensor includes a semiconductor containing polysilicon.

8. The detection device according to claim 6 , wherein the first sensor is provided on a side closer to the user than a keyboard as the input device, and the second sensor is provided on a side farther from the user than the first sensor is in the keyboard.

9. The detection device according to claim 6 , wherein the first sensor is provided in a button that the user presses in a mouse as the input device, and the second sensor is provided in a housing portion that is proximate to a palm of a hand of the user in the mouse.

10. An authentication method of authenticating a user using a detection device including an input device configured to receive an operation of the user and a sensor provided in the input device and configured to detect biological information of the user when the user operates the input device, the authentication method comprising determining whether a predetermined function is executed based on the biological information of the user that the sensor has detected,

wherein the input device includes an input device member and configured to receive an operation of a user, wherein the input device member includes a first input device member and a second input device member,

wherein the input device includes a sensor including a first sensor and a second sensor and configured to detect biological information of the user when the user operates the input device,

wherein the input device includes a light source unit including a first light source unit and a second light source unit,

wherein, in the input device, the first sensor is provided between the first input device member and the first light source unit, and

wherein, in the input device, the second sensor is provided between the second input device member and the second light source unit,

wherein the first sensor and the second sensor include a plurality of optical sensors, and

wherein the plurality of optical sensors of the first sensor include a first optical sensor and a second optical sensor exhibiting a sensitivity for different wavelength regions,

wherein the first optical sensor exhibits a first optical sensor sensitivity in a visible light wavelength region, and wherein the second optical sensor exhibits a second optical sensor sensitivity in a red wavelength region to an infrared wavelength region.

11. The method according to claim 10 , wherein the plurality of optical sensors, of the first sensor and the second sensor, are arranged in a matrix with a row-column configuration.

12. The method according to claim 10 , wherein the second sensor has a larger area than the first sensor.

13. The detection device according to claim 1 , wherein the plurality of optical sensors, of the first sensor and the second sensor, are arranged in a matrix with a row-column configuration.

14. The detection device according to claim 1 , wherein the second sensor has a larger area than the first sensor.
