Clickable trackpad designs generally aim to achieve a thin form factor with a minimized footprint that provides consistent user perception of click feel at scale within cost constraints. The clickable trackpad designs found herein adopt a mechanical depression mechanism that allows a user to register a click at any point on the trackpad surface with little variance in the depression force required to register the click. This provides a consistent click feel for the user. Further consistency of the click feel is achieved by establishing simultaneous travel of the entire trackpad surface, no matter where the click force is applied. This motion is a downward translation of the trackpad surface. An end user may press at any location of the trackpad surface to achieve a push button input (or click).

Mechanical flexural parallel motion trackpad

An electronic device includes a light source, a communication device, a processor in data communication with the light source and the communication device, and a hardware storage device in data communication with the processor. The hardware storage device has instructions stored thereon that, when executed by the processor, cause the electronic device to receive a timing signal from a camera, where the timing signal includes an exposure timing of a camera exposure; provide an exposure light pulse from the light source simultaneously with the camera exposure; and after providing the exposure light pulse, provide a dummy light pulse that does not overlap with a camera exposure.

Systems and methods for camera exposure controlled strobing lights

Examples are disclosed that relate to a camera model for a machine vision application. One example provides instructions executable to receive image data obtained by an image sensor of a camera, the image data capturing a calibration pattern comprising a plurality of calibration features, for each of one or more imaged calibration features in the image data, determine an object space location of the imaged calibration feature, and determine a distance between the object space location and a corresponding ray of a camera model, the camera model defining a plurality of rays that each represent a relationship of an image space location on the image sensor to object space. The instructions are further executable to determine a value of a cost function based on the distances, adjust the camera model until the cost function meets a target condition, and use the camera model in a machine vision application.

Calibrating a machine vision camera

One disclosed example provides a head-mounted device configured to control a plurality of light sources of a handheld object and acquire image data comprising a sequence of environmental tracking exposures in which the plurality of light sources are controlled to have a lower integrated intensity and handheld object tracking exposures in which the plurality of light sources are controlled to have a higher integrated intensity. The instructions are further executable to detect, via an environmental tracking exposure, one or more features of the surrounding environment, determine a pose of the head-mounted device based upon the one or more features of the surrounding environment detected, detect via a handheld object tracking exposure the plurality of light sources of the handheld object, determine a pose of the handheld object relative to the head-mounted device based upon the plurality of light sources detected, and output the pose of the handheld object.

Object and environment tracking via shared sensor

Examples are disclosed herein related to tracking poses of a head-mounted display device that interfaces with handheld peripheral objects. One disclosed example provides a handheld object configured for providing user input to a head-mounted device, the handheld object including a body, a plurality of visible light sources arranged on the body in an arrangement trackable by a vision system of the head-mounted device, and a controller configured to control a brightness of one or more visible light sources of the plurality of visible light sources.
