Systems, methods, and non-transitory computer readable media containing instructions for causing at least one processor to perform operations for determining a display configuration for presenting virtual content are provided. In one implementation, the processor is configured for receiving image data from an image sensor associated with a wearable extended reality appliance; analyzing the image data to detect a particular input device placed on a surface; determining a value of at least one use parameter for the particular input device; retrieving from memory default display settings associated with the particular input device; determining a display configuration for presenting virtual content based on the value of the at least one use parameter and the retrieved default display settings; and causing a presentation of the virtual content via the wearable extended reality appliance according to the determined display configuration.

A backlight apparatus includes a light-guiding plate, a light-shielding membrane, a light-reflecting sheet, a plurality of first translucent glue bodies, and a plurality of second translucent glue bodies. The light-guiding plate has a plurality of through holes. Each of the first translucent glue bodies corresponds to one of the through holes. Each first translucent glue body is placed on a front surface of the light-guiding plate, and surrounds a respective circumference of the corresponding through hole to bond the light-shielding membrane thereabove and the light-guiding plate therebelow. Each first translucent glue body has a respective breach. Each of the second translucent glue bodies corresponds to one of the first translucent glue bodies, is placed via at least one portion thereof in the breach of the corresponding first translucent glue body, and bonds the light-shielding membrane thereabove and the light-guiding plate therebelow.

A system for putting a computer device into sleep mode, the system being configured to: (a) activate a timer to count for a predetermined amount of time; (b) generate motion data with a radar module; (c) if motion data received from the radar module indicates that movement of a user of the computer device has been detected, then repeat steps (a) & (b); (d) if the timer has not expired, then repeat step (b); and (e) send a sleep mode instruction to the computer device.

This invention adds a touch screen to a hardware keyboard as additional input from handwriting for a PC or a laptop. The new keyboard with a small size touch screen provides convenient ways for handwriting notes, drawing graph or painting, converting handwritten characters to formal text. The new keyboard with a large size touch screen can work with a PC/laptop as a PC/laptop with the advantage of input from touch screen over traditional PC/laptop. The new keyboard with a large size touch screen can work with a PC/laptop as a tablet with the advantage of input from hardware keys and mouse over a regular tablet. The new keyboard with a large size touch screen can work with a PC/laptop as a PC/laptop and a tablet simultaneously, either PC/laptop or tablet with the advantage of additional said input ways over a traditional PC/laptop or a tablet. An optional fingerprint sensor provides fingerprint for security application, e.g., account login, document sign and identity verification.

An example keyboard module for a computing device may be separable and wirelessly communicable with a display module. In some examples, the keyboard module may include a wireless transceiver to receive a first audio signal from the display module and to transmit a second audio signal to the display module. The first audio signal may be output by a speaker on the keyboard module. The second audio signal may be captured by a microphone on the keyboard module. In some examples, the keyboard module may include a wireless display receiver to receive a display image from the display module. In some examples, the keyboard module may include a display output port to output the received display image for an external display.

Supplementing the movement stroke of a trackpad with a haptic response is one way to restore some or all of a reduced trackpad feel and overall performance caused by a reduction in the movement stroke. However, incorporating haptic responses in a clickable trackpad may interfere with accurate force measurement using physical movement of the trackpad as a proxy. The following describes haptic trackpads with anisotropic compliant spacers. The disclosed haptic trackpads permit selective haptic responses to a user, while also permitting accurate force measurement using displacement of a sensing surface caused by the user's finger(s) as a proxy.

A portable electronic apparatus including a first body, a second body, and a keyboard is provided. The second body is pivotally connected to the first body. The keyboard is disposed on the first body and includes a plurality of key structures. One of the key structures includes an elevating platform, a key cap, and a camera. The key cap is detachably mounted to the elevating platform, and the camera is mounted at one side of the key cap facing the elevating platform. After the camera is detached from the elevating platform together with the key cap, the camera is mounted and positioned to the second body together with the key cap, and at least a portion of the camera is exposed to the outside.

A keyboard includes keys protruding from an upper surface of the keyboard. The keys includes switches. The keyboard includes a printed circuit electrically coupled to the switches of the keys. The printed circuit is configured to generate signals responsive to operation of the switches of the keys. The keyboard includes a display below the upper surface of the keyboard. The display includes a visual side facing the upper surface of the keyboard. The display is configured to present content on the visual side of the display such that at least some of the content is visible through the upper surface of the keyboard.

Aspects of the present disclosure are directed to systems, apparatuses, and methods for the projection of images onto keycaps of a computer keyboard.
