An acoustic field may be produced from a transducer array having known relative positions and orientations In this acoustic field, one or more control points may be defined. An amplitude may be assigned to the control point. Mid-air haptic effect for a virtual object on a human body part may be generated by moving the control point in a single closed curve comprising a plurality of curve segments. The single closed curve traverses at least one location where the human body part intersects with the virtual object. Additionally, a user may interact with virtual three-dimensional content using the user's hands while a tracking system monitoring the user's hands, a physics engine updates the properties of the virtual three-dimensional content and a haptic feedback system provides haptic information to the user.

Disclosed is a touch control method for a display. The method includes: after a reflection signal is received by means of a receiving component of a laser sensor, generating an image according to a laser signal and the reflection signal; acquiring gesture information of a user according to the image; and executing a control operation corresponding to the gesture information. Further disclosed are a terminal device and a computer-readable storage medium.

A method and an apparatus for processing a screen by using a device are provided. The method includes obtaining, at the second device, a display screen displayed on the first device and information related to the display screen according to a screen display request regarding the first device, determining, at the second device, an additional screen based on the display screen on the first device and the information related to the display screen, and displaying the additional screen near the display screen on the first device.

Systems and methods to reduce accidental touch actions on a touchscreen are disclosed herein. An example electronic device includes a body including a first body portion and a second body portion that is movable relative to the first body portion. The first and second body portions are movable between a folded configuration and an unfolded configuration. The electronic device includes a touchscreen carried by the body, a sensor carried by the body, machine readable instructions, and processor circuitry to be programmed by the machine readable instructions. The processor circuitry is to determine, based on sensor data from the sensor, the body is being folded or unfolded, detect a touch on the touchscreen, and prevent a touch action corresponding to the touch based on the determination the body is being folded or unfolded.

A touch input device capable of detecting a pressure of a touch on a touch surface may be provided. The touch input device includes: a display panel; a substrate disposed under the display panel; and a pressure sensing unit. The pressure sensing unit includes a pressure sensor and a reference pressure sensor. When a pressure is applied to the touch surface, the display panel is bent. Electrical characteristics detected at the pressure sensor change by the bending of the display panel. A magnitude of the pressure applied to the touch surface is calculated based on a difference between a reference electrical characteristic calculated from electrical characteristics detected at the reference pressure sensor and the detected electrical characteristic calculated from the electrical characteristics detected at the pressure sensor.

A sensing apparatus comprising a displacement sensor element arranged to sense a separation between a first element (2) and a second element (3) movably mounted with respect to the first element; an acceleration sensor element configured to sense an acceleration associated with the first element; displacement measurement circuitry (4A) configured to make a measurement indicative of separation on the basis of the sensed separation; acceleration measurement circuitry (4C) configured to make a measurement of acceleration on the basis of the sensed acceleration; and a processing element (4D) configured to output a signal to indicate there is determined to be a change in the separation of the second element relative to the first element on the basis of the measurement indicative of separation and the measurement of acceleration.

Disclosed are a display apparatus, a control method thereof, and a computer control program product, the display apparatus including: a display configured to display a screen; a touch receiver configured to receive a user touch input; a sensor configured to detect a state of the display apparatus or surrounding states of the display apparatus; and a processor configured to perform a first operation based on a first touch input of a user, and control a second operation different from the first operation to be performed based on a second touch input made by the user or the state detected by the sensor during reception of the first touch input.

There is provided a touch substrate including a base substrate and at least one touch unit on the base substrate. Each touch unit includes capacitive touch electrodes including a first electrode and a second electrode and electromagnetic touch electrodes including a third electrode and a fourth electrode. An insulating layer is between the first and second electrodes. A resistance of a material of each of the electromagnetic touch electrodes is changed when a magnetic field where the electromagnetic touch electrode is located is changed. The insulating layer further extends between the third and fourth electrodes. The third and first electrodes are spaced apart from each other and are side by side on a same side of the base substrate, and the fourth and second electrodes are spaced apart from each other and are side by side on a side of the insulating layer distal to the base substrate.

A method for generating display data comprises detecting user input via an input interface. A processor is in communication with the input interface to generate display data comprising a display object for display by a display device. The display object is representative of an action that will subsequently be performed by the processor on continuation of the user input. The display data on the display device is output whilst the user input is being detected. Alternatively, the display object is caused to appear on the display device over time as the user input is being performed, wherein the rate at which the display object appears is different to the rate of performance of the user input. A device and executable computer program for performing the steps of the method is also provided.

A surgical instrument comprising a shaft, an end effector, a housing, a drive assembly, and a manually-driven actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an open position and a clamped position. The housing comprises a rotary input movable by a motor. The drive assembly is operably engaged with the rotary input. The drive assembly is movable by the motor in a motorized mode of operation to transition the second jaw toward the clamped position. The drive assembly is movable in a non-motorized mode of operation by the manually-driven actuator to permit a transition of the second jaw toward the open position to release tissue between the first jaw and the second jaw.
