A mute-able input device with keystroke tactile feedback includes: a plurality of keys, each including a tactile structure and a sound-generating structure for respectively generating operational tactile feedback and operating sounds; a plurality of adjusting mechanisms, each including an adjusting portion corresponding to one of the keys; at least one switching unit including an operating portion and a switch member, the operating portion connecting the switch member and the adjusting mechanism, the switch member generating a switching signal involving a mode switching between different tactile modes or different sound modes for one or more keys. When the operating portion moves in response to a force, the switch member is triggered to achieve the mode switching; meanwhile, the adjusting portion moves to interfere with at least one of the tactile structure or the sound-generating structure along with the movement of the operating portion.

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 virtual reality (VR) or augmented reality (AR) system includes: a display configured to display a user interface to a user; an integrated scrollwheel and fingerprint sensor (FPS) user input apparatus, comprising a scrollwheel configured to detect a rotational navigation input from the user and an FPS configured to detect a biometric input from the user; and a processing system configured to: receive the rotational navigation input via the scrollwheel of the integrated scrollwheel and FPS user input apparatus; update a displayed user interface on the display based on the received rotational navigation input, wherein updating the displayed user interface comprises updating a user selection on a displayed menu; receive an activation input for the updated user selection on the displayed menu via the FPS of the integrated scrollwheel and FPS user input apparatus; and execute an operation corresponding to the updated user selection on the displayed menu.

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.

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.

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 mouse as an example of an electronic equipment can be used in medical settings and includes a housing that can be gripped by a hand, a substrate which is arranged in a space in the housing and on which an electronic circuit component for calculating a state of the mouse is mounted, and an optical element (lens) which is arranged in a part of a bottom portion (housing bottom portion) of the housing and through which image light from outside enters. The optical element and the electronic circuit component are connected by a transmission unit capable of transmitting the image light. The substrate is arranged so as to be separated from the housing bottom portion upward in a Z direction by a distance between a lower surface of the housing bottom portion and a lower surface of the electronic circuit component in the Z direction and/or by a distance between an upper surface of the housing bottom portion and a lower surface of the substrate in the Z direction. For example, an optical fiber is used as the transmission unit.

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.
