Methods and devices for use in shuttle drills. The exercise device includes a base having a plate and a central vertical member configured to receive blocks retrieved during a shuttle drill, and several blocks configured to be placed at varying distances from the base and to be picked up by a participant and stacked on the base. The method includes placing blocks of varying colors at varying distances from a base that has a plate and a central vertical member. A participant is instructed to run to the block closest to the base, pick up the block closest to the base, run back with the block to the base and stack the block around the central vertical member, and to repeat the running, picking up, and running back steps until there are no more blocks to be picked up and all blocks are stacked around the central vertical member.

The present disclosure provides a centralised virtual and augmented reality activity system comprising a plurality of co-located virtual reality suites, each fully equipped with virtual reality accessories and set in an environment that is safe and spacious. The user devices of each suite are managed by a central server, also in the same location, which allows for interactions both between users of the different suites and facilitates normal interaction between the user devices and the internet.

An information processing device includes: a displacement information acquisition unit that acquires displacement information corresponding to 3-dimensional displacement of a predetermined portion of an object that a user mounts in accordance with a body motion on the basis of positional information of the predetermined portion and an output control unit that performs control such that an output unit performs a predetermined output on the basis of the acquired displacement information. The object has, for example, a seatback on which a user can sit. The displacement information acquisition unit acquires a change in a position in at least one of front and rear directions, right and left directions, or upward and downward directions of a seatback.

The invention relates to social activities typically based on physical manipulation of objects to achieve an objective common to the participants or to allow participants to engage in distinct activities on a shared field of play, part of which is physical and part of which is virtual and rendered on one or more displays. The invention provides a system and method to enable multiple participants (users) to engage in the activity sequentially or simultaneously, based on the context and objectives of the game. The activity includes one or many shared physical environments modeled on a computing system and displayed, in high fidelity, by one or more projectors or screens.

An upper limb exercise apparatus comprises a base, a frame, and a display mounted on the frame. The apparatus further comprises 5-bar linkage-type movable parts positioned on the display and including a first link and a second link. The first link comprises a 1-1 member having one end attached to the frame and being rotationally driven, and a 1-2 member having one end rotatably attached to the other end of the 1-1 member, the other end having attached thereto a handle for gripping. The second link comprises a 2-1 member having one end attached to the frame and being rotationally driven, and a 2-2 member having one end rotatably attached to the other end of the 2-1 member, the other end having attached thereto the handle and the other end of the 1-2 member. Series elastic actuators attached to the 1-1 member and the 2-1 member provide torque.

A gas purifying and processing method for exercise environment is provided and includes steps: (a) providing a purification device for exercise environment in an exercise environment, wherein the purification device for exercise environment includes a main body, a purification unit, a gas guider and a gas detection module; (b) detecting a particle concentration of the suspended particles contained in the purified gas in real time by the gas detection module; and (c) detecting, issuing an alarm and/or notification, and notifying an exerciser to stop exercising, and feeding back to the purification device to adjust an airflow rate of the gas guider by the gas detection module, wherein the gas guider discharge a gas at the airflow rate within 3 minutes to reduce the particle concentration of the suspended particles to less than 0.75 μg/m.sup.3, wherein the airflow rate is at least 800 ft.sup.3/min, and the main body maintains a breathing distance ranged from 60 cm to 200 cm.
