A pen-shaped folding mouse includes a scroll wheel, two supporting shafts, two rod bodies, two buttons, and an optical sensor. The scroll wheel has an axis line. The two supporting shafts are disposed on two opposite sides of the scroll wheel and are parallel to the axis line. The two rod bodies are located on the two opposite sides of the scroll wheel and are movably disposed on the two supporting shafts. The two rod bodies include two outer surfaces and two first end surfaces close to each other. The two buttons are disposed on the two outer surfaces of the two rod bodies. The optical sensor is located on the outer surface of one of the rod bodies.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

A method, computer program product, and a system where a processor(s) of a computing device identifies at least two displays coupled to the processor(s) to render visual objects to a user of the computing device, like a cursor, and processor(s) obtains instructions to render the cursor in various locations on the displays via an input device. The processor(s) obtain a display layout for the displays and resolutions of displays and generates an initial virtual desktop that includes physical real estate of the displays where the processor(s) renders visual objects. The processor(s) obtains a request and generates a simulacrum of the displays, in virtual space. The processor(s) displays, on a portion of the virtual desktop, the simulacrum. The processor(s) obtains, via the input device, a selection of a location on the simulacrum and automatically moves the cursor to a location on the virtual desktop that corresponds to the selected location.

There is provided an optical navigation device including an image sensor, a processing unit, a storage unit and an output unit. The image sensor is configured to successively capture images. The processing unit is configured to calculate a current displacement according to the images and to compare the current displacement or an accumulated displacement with a threshold so as to determine an outputted displacement. The storage unit is configured to save the accumulated displacement. The output unit is configured to output the outputted displacement with a report rate.

An optical navigation device includes a casing, a circuit board, an illumination light source and an optical receiver. The casing is movably located above a navigation surface. The circuit board is disposed inside the casing. The illumination light source is disposed on the circuit board and adapted to provide an illumination channel toward the navigation surface. The optical receiver is disposed adjacent to the illumination light source. An imaging channel of the optical receiver is substantially parallel to a planar normal vector of the navigation surface, and the optical receiver is adapted to identify features on the navigation surface within a range crossed by the imaging channel and the illumination channel for providing navigation information.

A method of docking an accessory device includes, at the accessory device, receiving (324) a first transmission energy for wireless charging from an electronic device; in accordance with receiving the first transmission energy: setting (326) a timer, and entering (328) a docked mode; and exiting (330) the docked mode upon expiration of the timer.

This disclosure provides systems, methods, and apparatuses for a trackball including an adaptive brake. In an aspect, an apparatus includes a trackball, a wheel coupled to the trackball and configured to rotate about an axis, and a brake system configured to apply a braking force to the wheel. In some aspects, the brake system includes a magnetorheological fluid (MRF) brake, such as an MRF rotational brake. The MRF brake may be configured to apply a braking force to the wheel.

An input device comprises a depressible element with two switches including a first switch configured to generate a first signal when the depressible element is depressed by a threshold distance and a second switch configured to generate a second signal indicating when the depressible element is depressed by the threshold distance and the second switch is in an active state. One or more processors may be configured to receive the first signal from the first switch; configure the second switch to change from an inactive state to an active state in response to receiving the first signal; receive the second signal from the second switch in the active state; determine whether the second signal indicates that the depressible element is depressed by the threshold distance; and generate event data confirming that the depressible element is depressed by the threshold distance in response to receiving the second signal.
