Abstract: A system and a method for interacting with an extended reality environment are provided. The method includes: generating, by a touch sensor with a detection area, a touch signal, wherein the touch sensor is included in a ring-type controller; providing, by a head-mounted display, an extended reality scene; determining, by the head-mounted display, whether an object is in the detection area according to the touch signal; in response to determining the object is in the detection area, generating, by the head-mounted display, a first command according to a movement of the ring-type controller; and moving, by the head-mounted display, a cursor in the extended reality scene according to the first command.

Abstract: The present disclosure provides a control device, a control method and a virtual image display system. The control device controls a display. The control device includes an optical sensing component, a touch sensing component and a controller. The optical sensing component is configured to acquire optical sensing data of the control device when the control device moves in an environmental space. The touch sensing component is configured to acquire touch data of the control device when the control device moves on a plane. The controller is configured to generate a handwriting image according to the optical sensing data and the touch data, such that the display displays the handwriting image.

Abstract: An object tracking method includes following steps: transmitting search information for searching for an object by a first processor during a search stage; receiving the search information and using a second processor to determine whether any of at least one accessory camera has captured an object image in the search stage. When the second processor determines that at least one of the at least one accessory camera has captured the object image, the second processor transmits notification information to the first processor and the first processor enters a tracking stage and transmits request information to the second processor. When the second processor receives the request information, the second processor performs one of the following: transmitting the object image to the first processor, wherein the first processor calculates an object pose according to the object image.
