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

In one embodiment, a method for charging a stylus of an information handling system includes: receiving, by a stylus docking slot of a keyboard of the information handling system, the stylus, the keyboard communicably coupled to the information handling system; causing, by a plurality of keyboard magnets of the keyboard, a partial alignment of the stylus in relation to the stylus docking slot, the plurality of keyboard magnets attracting a plurality of stylus magnets of the stylus; causing, by an alignment nub of the keyboard, an alignment of one or more spring contacts of the stylus in relation to one or more charging contacts of the keyboard, the alignment nub configured to removably couple to a beveled recess of the stylus; and providing, by the one or more charging contacts, power to an energy storage unit of the stylus via the one or more spring contacts.

A backlight module applicable to a key module is provided, the key module includes a plurality of key units and a baseplate, and the plurality of key units are disposed on the baseplate. The backlight module includes a lower substrate, a plurality of periphery light sources disposed along the peripheral of the baseplate, and a shielding structure. The lower substrate is disposed below the baseplate, and there is an outer edge gap between an outer edge of the baseplate and the lower substrate. The periphery light sources are disposed between the baseplate and the lower substrate. The shielding structure is disposed outside those periphery light sources distributed, to prevent light provided by the plurality of light sources from being emitted out of the outer edge gap.

The present disclosure provides a haptic feedback substrate, a haptic feedback apparatus and a haptic feedback method. The haptic feedback substrate comprises an actuator and a plurality of vibration units connected to the actuator, wherein each vibration unit has a different inherent frequency, the actuator is configured to generate a vibration signal and drive the vibration unit with the inherent frequency being a target inherent frequency to resonate, and a difference between the target inherent frequency and a frequency of the vibration signal is less than or equal to a present threshold. By controlling the actuator to generate the vibration signal, the vibration unit with inherent frequency being close to or equal to the frequency of the vibration signal is driven to resonate, thereby realizing local haptic feedback. The vibration units have different inherent frequencies, so the actuator may be controlled to sequentially generate vibration signals with different frequencies to realize local control and switching of the vibrations of the multiple vibration units to obtain different haptic perceptual signals. The present disclosure reduces the size of a touch feedback module and makes a touch feedback device more portable and intelligent.

The invention discloses a glasses waistband-type computer device, comprising a waistband body, wherein the middle of the front of the waistband body or other parts of the waistband body is detachably installed with a smartphone, and the front of the waistband body is further provided with a left keyboard located on the left side of the waistband wearer's navel and a right keyboard located on the right side of the waistband wearer's navel; the left and right keyboards are connected to the smartphone in a wired manner or a wireless including a Bluetooth manner. During man-machine interaction, the user wears a waistband so that the left keyboard is located to the left of the navel and the right keyboard is located to the right, to form a waistband keyboard. The invention is novel in structure, convenient to use, easy to carry, and can provide a good man-machine interaction mode.

A keyboard device includes a substrate, a touch panel module, a cover plate, a cover layer, an elastic layer, and an adhesive layer. The touch panel module is disposed on a top surface of the substrate and includes a circuit board. The cover plate covers the top surface and includes an avoidance hole defined through an upper surface and a lower surface of the cover plate. The cover layer covers the upper surface and includes a through hole. The through hole corresponds to the avoidance hole. The elastic layer is in the through hole and includes a peripheral portion. The peripheral portion is seamlessly connected to a hole edge of the through hole. The adhesive layer is adhered between a first inner surface of the cover layer and the upper surface and adhered between a second inner surface of the elastic layer and the circuit board.

Systems, methods, and non-transitory computer readable media for virtually extending a physical keyboard are disclosed. In one implementation, a non-transitory computer readable medium contains instructions that cause a processor to: receive image data representing a keyboard placed on a surface from an image sensor associated with a wearable extended reality appliance; determine that the keyboard is paired with the wearable extended reality appliance; receive an input for causing a display of a virtual controller with the keyboard; display, via the wearable extended reality appliance, the virtual controller in a first location on the surface, with original spatial orientation relative to the keyboard; detect a movement of the keyboard to a different location on the surface; and in response to the detected movement, present the virtual controller in a second location on the surface, with a subsequent spatial orientation relative to the keyboard that corresponds to the original spatial orientation.

A keyboard system comprises a housing and a key structure having a key body and key cap. The key body includes a transceiver circuit. The key cap includes a key cap transceiver and a memory structure storing a key cap ID data and/or a key function data corresponding to a key function. The transceiver circuit can poll the key cap memory via the key cap transceiver and retrieve the key cap ID data and/or the key function data. The keyboard system can determine a mapping of a location of the key cap on the keyboard by polling it and can generate and transmit a control signal to a host computing device communicatively coupled to the keyboard system based to the key cap ID and/or the key function data.

A backlight module applicable to a key module is provided, the key module includes a plurality of key units and a baseplate, and the plurality of key units are disposed on the baseplate. The backlight module includes a lower substrate, a plurality of periphery light sources disposed along the peripheral of the baseplate, and a shielding structure. The lower substrate is disposed below the baseplate, and there is an outer edge gap between an outer edge of the baseplate and the lower substrate. The periphery light sources are disposed between the baseplate and the lower substrate. The shielding structure is disposed outside those periphery light sources distributed, to prevent light provided by the plurality of light sources from being emitted out of the outer edge gap.
