A device implementing a system for machine-learning based gesture recognition includes at least one processor configured to, receive, from a first sensor of the device, first sensor output of a first type, and receive, from a second sensor of the device, second sensor output of a second type that differs from the first type. The at least one processor is further configured to provide the first sensor output and the second sensor output as inputs to a machine learning model, the machine learning model having been trained to output a predicted gesture based on sensor output of the first type and sensor output of the second type. The at least one processor is further configured to determine the predicted gesture based on an output from the machine learning model, and to perform, in response to determining the predicted gesture, a predetermined action on the device.

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 display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Generating interactive in-air images, by emitters emitting light pulses along an in-air detection plane, light detectors, lenses configured such that there is a particular angle of entry at which each detector receives maximal light intensity when pulses enter a lens corresponding to the detector at the particular angle of entry, and there are target positions in the detection plane, associated with emitter-detector pairs, whereby for each emitter-detector pair, when an object is located at the target position, then pulses emitted by the emitter are reflected by the object into the lens corresponding to the detector at the particular angle of entry, a projector projecting an image that appears, to a user suspended in the detection plane, and a processor identifying locations of the object in the detection plane and mapping the identified locations to corresponding locations in the image, to register user interactions with the image.

A display system for use in a Pepper's Ghost illusion includes a light emissive display, a sensor operable to detect the position of an attachment member of a cone, relative to the light emissive display, and a positioning processor operable to position images, which have been distorted by an inverse of the distortion caused by the reflection of the cone, responsive to the detected position of the cone relative to the light emissive display.

An optical processing apparatus and a light source luminance adjustment method adapted to detect a rotational displacement and a pressing state are provided. The optical processing apparatus includes a light source unit, a processing unit, and an image sensing unit, wherein the processing unit is electrically connected to the light source unit and the image sensing unit.
