20160378244 | ULTRASONIC TOUCH SENSOR-BASED VIRTUAL BUTTON - An apparatus including an electronic device is configured with an ultrasonic touch sensor-based virtual button. The ultrasonic sensor is disposed behind a first portion of an exterior surface of the electronic device. A processor associated with one or both of the electronic device and the ultrasonic sensor is configured to: (i) process a signal received from the ultrasonic sensor so as to acquire image data of a surface or substance in contact with the first portion of the exterior surface; and (ii) make a first determination whether or not the acquired image data is related to an intended control touch on the first portion by determining whether or not the image data is characteristic of a fingerprint or a patterned stylus. | 12-29-2016 |

20220137733 | REGISTRATION SYSTEM - A registration system is provided. The registration system includes: a display device, a collection device and an ultrasonic generating device. The display device is configured to display a graphical user interface. The collection device is configured to collect a scene image at the display device to recognize an operation of a user on the graphical user interface. The ultrasonic generating device is configured to emit ultrasonic signals, so that the ultrasonic signals gather to form one or more virtual buttons for operating the graphical user interface. | 05-05-2022 |
20220137734 | ELECTRONIC DEVICE AND TOUCH METHOD THEREOF - An electronic device is provided. The electronic device includes an ultrasonic input module and a control unit. The control unit is electrically connected to the ultrasonic input module. The control unit is configured to: continuously read a setting signal of the ultrasonic input module within a preset time to generate a threshold, where the setting signal includes a plurality of sensing values; receive an input signal by using the ultrasonic input module, where the input signal includes a feature value; and compare the feature value with the threshold to generate associated information, and process the input signal according to the associated information. The disclosure further provides a touch method applied to the electronic device. | 05-05-2022 |
