Claims14
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.
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.
