In some aspects, the disclosure is directed to methods and systems for a hybrid position and rate control input device comprising: a housing comprising an upper portion and a lower portion; a force-detecting sensor configured to detect a translation or rotation of the upper portion relative to the lower portion; a motion-detecting sensor within one of the upper portion and the lower portion of the housing, configured to detect motion of the housing relative to a surface; a communication interface positioned within the housing; and a processor positioned within the housing configured to select between a first translation signal from the motion-detecting sensor and a second translation signal from the force-detecting sensor; and transmit, via the communication interface to a computing device, the selected translation signal.

The sensor (1) for determining an orientation of the sensor in a gravity field comprises a ball (2) and a rolling surface (R) describing a generally concave shape on which the ball can roll inside the sensor. A further surface (F) is arranged opposite said rolling surface, and a light emitter (E), a light detector (D) and another light emitter or detector is provided. A region (R) within which the ball (2) can move is limited by at least the rolling surface (R) and the further surface (F). And the light emitters (E) and detectors (D) are arranged outside the region (R) for emitting light through the rolling surface (R) into said region and detecting light exiting the region (3) through the rolling surface (R) or for emitting light through the further surface (F) into said region (R) and detecting light exiting said region (R) through the further surface (F). Corresponding measuring methods and manufacturing methods are described, too.

A model controller includes a trackball having a spherical surface with one of latitudinal or longitudinal data tracks formed thereon. The model controller includes a base unit including a first image sensor adjacent to the trackball to capture images of the data tracks, wherein the captured images of the data tracks include orientation information to determine an absolute orientation of the trackball.

An example optical encoder includes a rotary shaft having a rotational axis. The rotary shaft is actuatable along the rotational axis. The optical encoder also includes at least one light generating element operable to generate light, and at least one light detecting element operable to detect light and convert the detected light into a signal. The rotary shaft includes a portion operable to reflect light generated from the at least one light generating element onto the at least one light detecting element wherein the signal is generated. The portion is configured such that an actuation of the rotary shaft from a first position to a second position generates a corresponding change in the signal generated in the at least one light detecting element.

The present disclosure is related to an optical encoder which is configured to provide precise coding reference data by feature recognition technology. To apply the present disclosure, it is not necessary to provide particular dense patterns on a working surface. The precise coding reference data can be generated by detecting surface features of the working surface.

A rotation operation device includes: a rotation shaft including a first end portion and a second end portion spaced apart from each other in an axial direction of the rotation shaft; a knob having conductivity, the knob being provided at the first end portion of the rotation shaft and being configured to rotate the rotation shaft; a touch sensor configured to detect a contact with the knob; and an elastic body having conductivity, the elastic body including a first end connected to the knob and a second end connected to the touch sensor. The knob includes a surface facing in the axial direction of the rotation shaft towards the second end portion of the rotation shaft, the surface of the knob includes a recess portion recessed in the axial direction, and the first end of the elastic body is disposed in the recess portion.

A roller input device includes a housing, a passive member and an active member. A roller is pivotally disposed inside the housing, and the roller includes an annular tooth portion. The passive member is movably disposed inside the housing, and the passive member includes an abutting portion and a first magnetic module. The active member has a second magnetic module, and the active member is disposed inside the housing and operably moved to a first mode or a second mode to make the first magnetic module and the second magnetic module attract each other or make the first magnetic module and the second magnetic module repel each other to drive the passive member to move relative to the housing to a first position or a second position, such that the abutting portion and the annular tooth portion abut against or separate from each other.

An optical detection device capable of detecting a pointer position of a turntable watch includes an optical receiver and a processor. The optical receiver is disposed inside the turntable watch and adapted to receive an optical reflecting signal. The processor is electrically connected to the optical receiver and adapted to compare a physical quantity of the optical reflecting signal with a predefined condition for determining whether a pointer of the turntable watch is located above the optical receiver. The optical detection device further includes an optical emitter electrically connected to the processor and adapted to emit an optical detecting signal. The optical detecting signal is projected onto the pointer to generate the optical reflecting signal.

An electronic apparatus includes a structure and an optical navigation circuit. A first end of the structure is located inside the electronic apparatus and its second end corresponds to a user's control. The structure can be moved forward/backward in a specific direction and/or rotated in another direction. The optical navigation circuit captures reflection of a light emitting to the structure to detect displacement of the image along a specific axis of the structure, and determines the user's operating behavior as a specific operation according to a change of the sensed displacement of the image.
