An example discloses a smart ring comprising a processor; a transceiver, wherein the transceiver is coupled to the processor to receive instruction from the processor and the transceiver is coupled to a computing device for transmitting data of the smart ring to the computing device and/or receiving data from the computing device; and a G-sensor, wherein the G-sensor is coupled to the processor and configured to detect up and down movement of the smart ring.

Examples relate to determining finger movements. In one example, a computing device may: receive input from at least one of: a first proximity sensor coupled to the frame at a first position and facing a first direction; or a second proximity sensor coupled to the frame at a second position and facing a second direction; determine, based on the input, that a finger action occurred, the finger action being one of: a first movement of a first finger, the first movement being detected by the first proximity sensor; a second movement of a second finger, the second movement being detected by the second proximity sensor; generate, based on the finger action, output that includes data defining an event that corresponds to the finger action; and provide the output to another computing device.

A handheld controller is suitable for controlling a virtual reality system. The handheld controller has a pointer direction corresponding to the virtual reality system. The handheld controller includes a holding portion, a knob, and a positioning module. The holding portion is suitable to be held by a hand of a user. The knob is pivotally connected to the holding portion on a rotation axis. The rotation axis is coaxial with or parallel to the pointer direction. The positioning module is connected to the holding portion and is configured to provide a position of the holding portion in a three-dimensional space. In addition, a control method is also provided here.

The embodiments of the disclosure provide a method for detecting a movement of a ring controller, a ring controller, and a computer readable medium. The method includes: obtaining a plurality of moving parameters of the movement of the ring controller, wherein the ring controller is used to interact with a user interface; determining a rotating condition of the ring controller based on the moving parameters; and adjusting a visual content provided in the user interface based on the rotating condition of the ring controller.

An operation device includes: a detector adapted for being mounted at least to a thumb or an index finger, and configured to detect changes in flexion with time at a joint and in pressing with time at a tip of the thumb or the index finger; a recording unit configured to record operation information representing association between: each of the change in flexion and the change in pressing; and operations performed by any of the thumb and the index finger on an external device; a determination unit configured to determine the operation included in the operation information, based on the change in flexion and the change in pressing; and a control unit configured to generate a control signal for causing the external device to perform a predetermined operation, according to the determined operation, and transmit the control signal to the external device.

A defined class of input devices is disclosed, consisting of a graspable body in two forms. Both forms include a scroll wheel-style mechanism that functions as a button from multiple directions, both include an apparatus providing six degrees of gestural freedom in three dimensions, and both provide for the wireless transmission capacity of these inputs, user data, audio, and other communications for the purpose of carrying credentials among various host electronic devices, and for manipulating and navigating an associated user interface for hierarchy visualization of structured information to be displayed on those host devices.

A finger-mounted computer stylus is provided. The stylus is pivotable between an operative position extending forward past the middle knuckle along a backhand area and an inoperative position wherein the stylus does not extend forward past the middle knuckle. Magnets along the upper surface of a base and associated pivot arm removably secure the stylus in the operative and inoperative positions by way of a magnetic connection adapted to be disconnected with a snap of the wrist.

A wearable ring-shaped electronic device having a ring portion engageable with a first finger of a user wearing the device is provided. The ring portion includes an interface, and a display unit operatively coupled with the ring portion. The display unit comprising a face that is coupled with any or a combination of a face cover and a face edge such that, upon interaction between a second finger of the user and the interface, interaction-based data is transmitted to and processed by at least one processor of the device so as to enable one or more notifications to be either displayed on any or a combination of the face cover and the face edge, or audibly notified to the user.

A portable device for translation of digital content on a display into braille includes: a conductive material located adjacent an end of the portable device for contacting a display of a touchscreen device; a microcontroller located on a body of the portable device; a communications module in electronic communication with the microcontroller; and a first braille cell comprising a plurality of movable individual braille elements, the individual braille elements collectively capable of forming braille alphabet letters. The microcontroller receives a command via the communications module to create a braille character on the first braille cell in response to the conductive material contacting the display of the touchscreen device, the braille character corresponding to a character displayed on the display of the touchscreen device at the location the conductive material contacts the display.

Disclosed is a wearable device. The wearable device includes an optical signal transmission unit configured to transmit optical signals, an optical signal sensing unit configured to receive reflected optical signals generated upon reflection of the optical signals by an object, a data processing unit configured to process the received reflected optical signals, and a key determination unit configured to sense a user's key input motion based on data acquired by processing the reflected optical signals and to generate an input value matching the key input motion.
