A method for detecting an operating input performed by a finger involves detecting various contact points of a contour of the finger using a sensor system on a sensor surface. The sensor system includes at least one transmitting unit for transmitting a signal to the finger and at least one receiving unit for receiving a signal reflected by the finger. A surface vibration is introduced into the sensor surface by at least one actuator, the surface vibration changes the frictional resistance between the finger and the sensor surface as a function of the changing contact points of the contour of the finger.

A display screen module includes a display screen and a fingerprint identification unit. The display screen includes a front display area and a side display area. The side display area at least partially covers the fingerprint identification unit, and the fingerprint identification unit is configured to obtain a fingerprint image. As the fingerprint identification unit is at least partially covered by the side display area, it can reduce or even needs not to occupy under-screen space of the front display area, and arrangement of the components can be optimized. When the user directly holds the side display area to which the fingerprint identification unit corresponds, fingerprint unlocking can be executed directly, which brings new fingerprint unlocking experience to the user, and also makes the unlocking process easier.

A virtual and augmented reality instruction system may include a complete format and a portable format. The complete format may include a board system to capture all movement (including writing and erasing) on the board's surface, and a tracking system to capture all physical movements. The portable format may include a touch-enabled device or digital pen and a microphone, and is designed to capture a subset of the data captured by the complete format. In one embodiment of the complete format, the board system and the tracking system can communicate with each other through a network, and control devices (such as a laptop, desktop, mobile phone and tablet) can be used to control the board system and tracking system through the network. In further embodiments of the complete format, augmented reality can be achieved within the tracking system through the combination of 3D sensors and see through augmented reality glasses.

A touch sensing apparatus is disclosed for detecting touch pressure, comprising a panel that defines a touch surface, the panel having a perimeter, a plurality of emitters arranged along the perimeter, wherein the emitters emit light across the panel, a plurality of detectors arranged along the perimeter, whereby the detectors are arranged to receive at least part of said light as detection light, wherein the touch sensing apparatus is configured to determine, as a touch object deflects the panel along a normal of the touch surface, a difference in the received detection light between deflection of the panel from a first position (p1) to a second position (p.sub.2) along the normal, and determine a pressure of the touch object against the touch surface based on said difference.

An information processing apparatus includes a display unit, a first detection unit that detects a position of an object located in a vertical direction with respect to the display unit and that interacts with the display unit in a contactless manner, wherein detecting the position results in detecting an instruction associated with the at least one input object that is displayed on the display unit and corresponds to the position of the object, a second detection unit configured to detect confirmation of the instruction detected by the first detection unit, and an input unit configured to input data corresponding to the at least one input object in a case where the second detection unit detects confirmation of the instruction associated with the at least one input object in a state where the first detection unit detects the instruction associated with the at least one input object.

The present application provides a touch display panel. In the touch display panel, a frame is provided with a first accommodation space, a first accommodation slot, and a second accommodation slot; a display pane disposed in the first accommodation space, infrared emitting modules disposed in the first accommodation slot and at a periphery of a light-emitting side of the display panel; and infrared receiving modules disposed in the second accommodation slot and at the periphery of the light-emitting side of the display panel.

An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device can include an optical waveguide, an emitter, and an emitter coupler. The emitter produces optical beams, and the emitter coupler is on a surface of the waveguide and is configured to direct at least some of the optical beams to propagate via total internal reflection (TIR) through the waveguide as coupled optical beams. Touches on the top surface of the waveguide disturb the coupled optical beams, and the touch-sensitive device determines touch events based on the disturbances.

An interface for a medical device, in particular an extracorporeal blood treatment machine or a dialysis machine, includes a display for displaying display operating elements, base operating elements provided next to the display, and an optical actuation sensor. The optical actuation sensor detects a user interaction with, in particular a touching of, the display operating elements of the display and the base operating elements disposed in the same plane. The optical actuation sensor can be partially activated or deactivated.
