Abstract: An antenna is configured to receive authentication information through wireless communication from a mobile device adapted to be carried by a user. A detector is configured to perform detection of approach or contact of an object to be detected with respect to the antenna based on a change in an electrostatic capacitance. A control device is configured to control an operation of a device to be controlled based on a result of the detection in addition to authentication for authenticating the mobile device with the authentication information.

Abstract: A display device is provided with an input unit for inputting a detection signal from a detection unit capable of detecting the brightness of ambient light around a dimming member. The display device is also provided with a control unit which, on the basis of the detection signal input by the input unit, controls at least one of the optical transmittance of the dimming member and the operation of a projector to adjust an image projected onto the dimming member to a display state corresponding to the brightness of the ambient light.

Abstract: There is provided a learning device, including a learning unit that learns output related to a target feature point to be observed in a repetition section observed periodically, with the use of the first sensor data being acquired by the first system and having a time length corresponding to the repetition section, as learning data, and of teacher data based on the second sensor data acquired by the second system at a time point when a specific period of time has elapsed since a start time point of the time length related to the first sensor data, the second system being less affected by noises than the first system, in which the specific period of time is set on the basis of a time length from a start time point of the repetition section to a time point at which the target feature point is expected to appear.

Abstract: An operation detection device includes a detection unit to detect a physical quantity changing upon approach or contact of a detected object to or with an operation surface and to output detection information allowing for calculation of coordinates of an approach or contact position of the detected object, and a control unit to, when the physical quantity based on the detection information satisfies a predetermined condition, calculate and set first detected coordinates of the detected object as reference coordinates and does not perform coordinate update when coordinates calculated after the reference coordinates are included in a first region centered at the reference coordinates, and when coordinates calculated after the reference coordinates are outside the first region, set a second region narrower than the first region and perform the coordinate update, and when coordinates calculated after the updated coordinates are included in the second region, not to perform the coordinate update.

Abstract: A system is mounted on a vehicle and includes a sensor configured to perform a detection process that detects a fingerprint of a finger touching the sensor in order to perform a fingerprint authentication process, and a controller. The controller is configured to: (i) control a power supply of the vehicle to be ON when a predetermined authentication process through a predetermined communication with another device other than the sensor is successful, the predetermined authentication process being different from the fingerprint authentication process, and (ii) suppress the detection process that detects the fingerprint in response to the power supply of the vehicle being ON and the predetermined authentication process being successful.

Abstract: There is provided a control device including a control unit that controls tactile sense presentation for presenting a stimulation through a tactile sense and hearing sense presentation for presenting a stimulation through a hearing sense, when it is determined that an operation has been performed on an input unit including a contact area with which an object is brought into contact. The control unit controls displacement indicating a difference from a reference position of the contact area, the displacement being related to the tactile sense presentation, and a strength of sound related to the hearing sense presentation, so that at least one of the tactile sense presentation and the hearing sense presentation is in a proper range that is a range allowing a user of the input unit to perceive the presentation and not causing the user to have unpleasant feeling.

Abstract: A control device including a control section configured to vibrate a contact region in a case where it is determined that an operation is performed on an input section by a target object coming into contact with the contact region, the input section having the contact region touched by the target object, wherein the control section adjusts an acceleration peak-to-peak value as a control parameter for performing control of vibrating the contact region, the acceleration peak-to-peak value being a difference between a local maximum value and a local minimum value of acceleration applied by vibration to the contact region.
