A method for fingerprint recognition is provided. An electronic device includes a touch screen. The touch screen has a fingerprint recognition area. The fingerprint recognition area is capable of being pressed by at least two fingers. The method includes the following. Touched areas in the fingerprint recognition area are selected as target touch areas upon detecting a touch operation on the touch screen. One target touch area corresponds to one finger which applies pressure to the touch screen. A fingerprint image in each target touch area is acquired to obtain at least one fingerprint image. Determine whether each of the at least one fingerprint image is matched with a corresponding fingerprint image template of a preset fingerprint image template set. A preset operation corresponding to the touch operation is triggered, upon determining that each of the at least one fingerprint image is matched with a corresponding fingerprint image template.

Systems and methods are provided for ultrasonic haptic array devices. One embodiment of haptic array device includes a plurality of cells, each cell including a base and an array of ultrasonic transducer elements, and a support structure configured to independently position each cell. A controller of the haptic array can control a focus point and a direction of ultrasonic output for each of the plurality of cells. Another embodiment is directed to a vehicle user interface having a user interface surface and a haptic array device integrated with the user interface surface.

One method includes controlling output of at least one first cell of the plurality of cells to control a focus point and a direction of ultrasonic output of the at least one cell, and updating output of the plurality of cells.

In a first state before a first event is detected, a determination unit of a press detection apparatus prevents a definitive value from increasing steeply when the pressing force has increased steeply, and decreases the definitive value steeply when the pressing force has decreased steeply. In a second state after the first event is detected and before a second event is detected, the determination unit prevents the definitive value from increasing steeply when the pressing force has increased steeply, and prevents the definitive value from decreasing steeply when the pressing force has decreased steeply. This reduces the possibility that the definitive value increases steeply in the first state and increases and decreases steeply in the second state even under vibration.
