Abstract: The embodiments of the disclosure provide a method for hand tracking. The method includes following steps. A first image of a hand is obtained through a head-mounted device. A first pose of a first part of the hand is determined through a processor based on the first image. A second image of the hand is obtained through a hand-held device. A second pose of a second part of the hand is determined through a processor based on the first image. The first part and the second part complementarily form an entirety of the hand. A gesture of the hand is determined through the processor based on the first pose and the second pose.

Abstract: A management method for multiple communication devices, wherein the multiple communication devices include a host device and a first peripheral device configured to electrically connect to a device platform, and the management method includes: by the host device, detecting a connection of the first peripheral device through the device platform; by the host device, receiving a first device identifier provided by the first peripheral device through the device platform; by the host device, storing the first device identifier in the host device; and by the host device, wirelessly pairing the host device with the first peripheral device, according to the first device identifier stored in the host device, to enable a first wireless communication between the host device and the first peripheral device.

Abstract: A controller includes a body and a surrounding part. The body has a control area for sending a control signal according to a movement of a thumb of a user. The surrounding part is connected to the body and used to surround and be fixed to a proximal phalange of an index finger of the user. The body is away from a joint between the proximal phalange and a metacarpal bone of the user.

Abstract: The embodiments of the disclosure provide a method for hand tracking. The method includes: obtaining, through a head-mounted device, a first image of a hand; determining, through the processor, a first pose of a first part of the hand based on the first image; obtaining, through a hand-held device, a second image of the hand; determining, through the processor, a second pose of a second part of the hand based on the second image, wherein the first part and the second part complementarily form an entirety of the hand; and determining, through the processor, a gesture of the hand based on the first pose and the second pose.

Abstract: A handheld controller is adapted to control an electronic device. The handheld controller includes a first body, a second body, and a connecting portion. The first body is adapted to be held by a user's hand. The second body is connected to the first body through the connecting portion. The connecting portion is adapted to be clamped between user's fingers. A distance between the first body and at least a portion of the second body is variable.

Abstract: A hand controller assembly including a hand controller, a slide rail and a strap. The hand controller has a top and a bottom opposite to each other. The slide rail is disposed at the top and has an entrance and a limiting portion adjacent to the entrance. The strap is detachably assembled to the slide rail and the bottom. The strap includes a body and a metal member. The metal member is assembled to one end of the body. The metal member has a sliding block. The sliding block is adapted to be detachably assembled to the slide rail via the entrance along a direction. The sliding block is adapted to move along the limiting portion. The limiting portion restricts the movement of the sliding block along the direction.

Abstract: A handheld electronic device including a holding assembly and a tracking assembly is provided. The tracking assembly includes a main body and a plurality of trackers. The main body is connected to the holding assembly and has an inner surface and an outer surface. The trackers are disposed on the inner surface and the outer surface of the main body. The trackers arranged on the outer surface and a part of the trackers arranged on the inner surface are exposed to the outside in a top view direction and are arranged in interleaving.

Abstract: A hand strap and a hand controller assembly are provided. Two ends of the hand strap are respectively used for connecting a hand controller. The hand strap includes an elastic strap, a belt body, and a locking mechanism. The locking mechanism includes a fixed assembly and a sliding assembly. When a relative position of the fixed assembly and the sliding assembly is in a locked state, the fixed assembly and the sliding assembly clamp and fix the elastic strap. When the relative position of the fixed assembly and the sliding assembly is in an unlocked state, the fixed assembly and the sliding assembly release the elastic strap. When the elastic strap is not subjected to an external force, an elastic force of the elastic strap drives the relative position of the fixed assembly and the sliding assembly to be maintained in the locked state.
