An input device with a backlight function and a backlight color adjustment method are provided. The input device with the backlight function includes a casing, plural color light-emitting elements, a control module and a charge-coupled device. The control module provides electric power to at least two selected color light-emitting elements through a power supply circuit. By the control module, the chromaticity value of a mixed white light beam from the color light-emitting element is adjusted to be consistent with the chromaticity value of a white light beam, and the luminance value of the mixed white light beam from the color light-emitting element is adjusted to be consistent with the luminance value of the white light beam.

According to an embodiment of the present disclosure, a display device may include a wireless communication unit configured to wirelessly receive a first video signal based on a first video being displayed by a terminal, a display unit configured to display a first mirroring video based on the first video signal, and a control unit configured to receive a user input while the first mirroring video is being displayed, and transmit, to the terminal, a packet that does not include a mouse cursor parameter for requesting coordinates of a mouse cursor when the received user input is a touch input.

A system for promoting user manipulation of pointing device while operating keyboard is provided. The system comprises a computer, a USB device coupled to the computer, and a handheld wireless pointing device with a first surface positioned against a palm of a user's hand. The device receives tactile contact from a thumb of the hand on a touchpad on a second surface, the second surface opposite the first surface and facing away from the palm. The device also measures movement of the thumb on the second surface and transmits messaging to the USB regarding the measured movement. The USB, based on the received messaging, directs movement of a cursor on a display of the computer. The movement of the cursor is aligned with the movement of the thumb. The device receives attachment to the hand via loops attached to user index and middle fingers.

A method for generating a special effect prop includes displaying a special effect prop editing page and acquiring a first image, where the special effect prop editing page is provided with a flow information display region and an effect display region, where the flow information display region is used for displaying flow information of a prop to be edited, and the effect display region is used for displaying a second image, where the second image is a preview image obtained by processing the first image according to the flow information; in response to an editing operation, editing the flow information and updating the second image; and in response to a special effect prop generation operation, generating a target special effect prop according to edited target prop flow information.

A device for online gaming includes an actuation component and a controller communicatively coupled to a computer system. The controller is configured to perform operations including detecting an actuation of the actuation component, wherein the actuation component is associated with performing of an action in a video game executed by the computer system. Responsive to detecting the actuation, an instruction is provided to the computer system to perform the action, wherein, based on a current value of a timer, the computer system restricts the action from being performed. The timer, having been previously initiated based on a prior actuation of the actuation component, relates to a cooldown period during which the action cannot be repeated after the action is performed. Responsive to receiving a command from the computer system, a tactile effect is generated as an indication to a user that the action can be repeated.

The present invention discloses a scroll wheel module, which comprises a bracket and a rotatable scroll wheel that is arranged on the bracket. The scroll wheel is equipped with a hand feel member that provides flipping tactile. The scroll wheel module further comprises an electronic control adjustment assembly, which is used to adjust the magnitude of damping that the hand feel member exerts on the scroll wheel. By tactfully combining the electronic control adjustment assembly with the hand feel member, the present application can adjust the height of the tilting end simply and quickly by means of the electronic control adjustment assembly, further adjust the distance between the hand feel end of the hand feel member and the inner ring of the scroll wheel, and finally manage to adjust different kinds of tactile sense about the damping while rolling the scroll wheel.

An input module includes a knob, a first circuit board, an optical transmitter and an optical receiver. The knob has a peripheral surface. The optical transmitter is disposed on the first circuit board and faces the peripheral surface, wherein the optical transmitter is configured to emit a detecting light to the peripheral surface. The optical receiver is disposed on the first circuit board and configured to receive a reflected light of the detecting light reflected from the peripheral surface.

There is provided an illumination system of a navigation device including a light beam shaping optics, and a first light source and a second light source having different characteristics. The light beam shaping optics is used to shape light beams emitted by the first light source and the second light source to illuminate a work surface with substantially identical incident angles and/or beam sizes.

An input device includes a casing, a first pressable portion, a second pressable portion, and at least one haptic generator, the casing includes a palm-supporting portion and at least one sidewall connected to each other, the first pressable portion and the second pressable portion are located adjacent to the palm-supporting portion of the casing, the first pressable portion, the second pressable portion, and the at least one sidewall are respectively located at different sides of the palm-supporting portion, the at least one haptic generator corresponds to the at least one sidewall and is configured to vibrate the at least one sidewall.

This application provides a display method and a device and relates to the field of communications technologies, so as to display different content on a terminal and an external display apparatus. A specific solution includes: displaying, by the terminal, a first screen, and instructing the external display apparatus to display a first desktop including a first application but not including a second application, where the first screen is different from the first desktop; and displaying, by the terminal in response to a first input of a user on the first screen, a second screen including the first application and the second application on the terminal, and instructing the external display apparatus to display a second desktop including the first application and the second application.
