A wireless controlling system including a smart ring and an identification program installed in a mobile device is disclosed. The ring includes an MCU, a six-axis accelerometer, a transmitting unit and a storage. The storage stores multiple gesture models respectively corresponding to different moving trajectories. When a user moves with the ring, the six-axis accelerometer continuously detects a set of moving signals of the ring. The MCU continuously determines whether the set of moving signals matches any moving trajectory of the gesture models. When a gesture model is matched, the MCU sends a gesture command corresponding to the matched gesture model to the mobile device through the transmitting unit. The mobile device analyzes the gesture command to obtain a corresponding operation command through the identification program, and the mobile device is being controlled to execute a corresponding function in accordance with the operation command.

Described are apparatus and methods for reconstructing a full human skeletal pose or a partial skeletal pose by aggregating and fusing various data from various sensors, and for detecting the occurrence of gestures from poses that occur over a period of time.

A finger-gesture detection device adapted for a control handle includes a grip portion. The finger-gesture detection device includes a first wearing portion, a plurality of second wearing portions, and a plurality of first sensors. The first wearing portion is adapted to detachably surround the grip portion of the control handle.

When a force is applied to one of the second wearing portions, the corresponding second wearing portion moves toward the grip portion. The first sensors are respectively disposed on the second wearing portions for detecting positions or movements of the second wearing portions relative to the grip portion. A control assembly and a correction method are also proposed.

The method includes, in accordance with a determination that the third position satisfies a proximity threshold with respect to the second position, merging the first computer-generated object with the second computer-generated object in order to generate a third computer-generated object for modifying the content item. The method includes displaying the third computer-generated object.

An electronic device may have a fiber composite friction hinge with first and second members that rotate relative to each other about a hinge axis. The fiber composite hinge may have first and second sets of interdigitated elongated fingers. Holes in the elongated fingers may receive a shaft of a fastener. The fastener may be tightened to squeeze the elongated fingers together along the hinge axis. The fiber composite hinge may be formed from a fiber composite material such as carbon fiber composite material. Fibers in the composite material may be embedded in binder such as polymer binder. The fibers may wrap around the holes and fold back on themselves in the fingers. Actuators may be provided to adjust the positions of portions of the hinge members. The electronic device may have a flexible layer such as a flexible display that overlaps the hinge structure.

A fingertip protective cover to reduce transmission of germs, viruses and the like when a person’s fingertip contacts a touchscreen, such as are used on many electronic devices. A dome shaped main body has a convex top surface, adapted for contact with touchscreen contact points. A bottom surface has a concave recess for receiving a portion of a human fingertip. At least the recess of the fingertip protective cover is sufficiently self-adhesive to releasably adhere to the fingertip in use, or alternatively an adhesive is disposed in the recess. The top surface is electrically conductive to permit use with electrically conductive (capacitive) touchscreens. The entirety of the fingertip protective cover may be formed of an electrically conductive material, or alternatively the top surface may be covered with a layer of electrically conductive material.
