An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

Compound-operation input device

A compound-operation input device includes an operating member; a rotary mechanism configured to hold the operating member such that the operating member is rotatable; a slide mechanism configured to support the operating member such that the operating member is slidable in a sliding direction intersecting a rotation axis of the rotary mechanism; and a noncontact detector including a plurality of noncontact sensors and configured to detect a direction of movement and an amount of movement of a detection object, the detection object moving together with the operating member. The noncontact detector is one of a pair of noncontact detectors provided across the rotation axis from each other on a rotation locus of the detection object, the pair of noncontact detectors being at respective positions on a straight line orthogonal to the sliding direction.

Finger devices with proximity sensors

A system may include one or more finger devices that gather input from a user's fingers. The system may include control circuitry that sends control signals to an electronic device based on the input gathered with the finger devices. A finger device may include one or more proximity sensors that measure a distance to the user's finger. The proximity sensor may be a self-mixing optical proximity sensor having a laser and photodiode. The proximity sensor may have submicron resolution and may be configured to detect very small movements of the finger as finger pad is moved around by a thumb finger, by a surface, and/or by other finger movements. The proximity sensor may measure changes in distance between the proximity sensor and a flexible membrane that rests against a side portion of the user's finger.

A touchless trigger apparatus is touchless button, comprising a photon-gate side, a photon-gate distal side more than 1 cm (11.0 in) and less than 30 cm (11.0 in) across the photon-gate opening, to the photon-gate side. An electro-optical sensor is connected to the photon-gate side. An ASIC controller is connected to the output of the electro-optical sensor. Lastly a button face is within the opening of the photon gate. Alternatively, a touchless trigger apparatus is a touchless pushbutton, or a touchless switch. Any person or primate trained to use a button, pushbutton or switch could intuitively learn to use a touchless trigger apparatus due to its recognizable combination of elements and low-latency feedback before touching the button, the pushbutton or the switch.
