A rotating assembly and a handle having the same are disclosed. The rotating assembly comprises a rotary shaft (1), an accommodating body (2) and a position-limiting switch (3). An outer wall of the rotary shaft (1) is provided with a first tenon (11) and a second tenon (12). The accommodating body (2) is provided with a matching hole (21) for the first tenon (11) to insert and rotate therein. An inner wall of the matching hole (21) is provided with a convex rib (22). By rotating the rotary shaft (1), a side wall of the first tenon (11) and a side wall of the convex rib (22) butt against or separate from each other, so that in an axial direction of the rotary shaft (1), the rotary shaft (1) is fixed or movable relative to the accommodating body (2). When the side wall of the first tenon (11) and the side wall of the convex rib (22) butt against each other, the position-limiting switch (3) and the second tenon (12) are clamped together to prevent the rotary shaft (1) from rotating relative to the accommodating body (2). The handle having the rotating assembly has a body portion that can flip with respect to two gripping portions, so the handle can be applied to various occasions.

A human-machine interface involves plural spatially-coherent visual presentation surfaces at least some of which are movable by a person. Plural windows or portholes into a virtual space, at least some of which are handheld and movable, are provided by using handheld and other display devices. Aspects of multi-dimensional spatiality of the moveable window (e.g., relative to another window) are determined and used to generate images. As one example, the moveable window can present a first person perspective “porthole” view into the virtual space, this porthole view changing based on aspects of the moveable window's spatiality in multi-dimensional space relative to a stationary window. A display can present an image of a virtual space, and an additional, moveable display can present an additional image of the same virtual space.

A system for a trend-based guessing game includes an electronic communication and display device, configured with software to enable the electronic communication and display device to communicate with a cloud server that accesses a trend database to download a trend. The system also includes a pair of glasses configured to be worn by a user, the glasses including communication and display driver electronics and a glasses electronic display configured to display the downloaded trend on the glasses electronic display, the glasses electronic display configured such that the user cannot read the display when wearing the glasses.

A method to identify positions of fingers of a hand is described. The method includes capturing images of a first hand using a plurality of cameras that are part of a wearable device. The wearable device is attached to a wrist of a second hand and the plurality of cameras of the wearable device is disposed around the wearable device. The method includes repeating capturing of additional images of the first hand, the images and the additional images captured to produce a stream of captured image data during a session of presenting the virtual environment in a head mounted display (HMD). The method includes sending the stream of captured image data to a computing device that is interfaced with the HMD. The computing device is configured to process the captured image data to identify changes in positions of the fingers of the first hand.

Handheld location based games are provided in which a user's physical location correlates to the virtual location of a virtual character on a virtual playfield. Augmented Reality (AR) systems are provided in which video game indicia are overlaid onto a user's physical environment. A landscape detector is provided that may obtain information about the user's landscape, in addition to the user's location, in order to provide overlaying information to an AR head-mounted display and control information to non-user controlled video game characters.

Systems and methods of multi-participant interactive experiences are disclosed. Participants located location can interact with one another and share gaming, educational and other experiences. The system includes a coordination node to coordinate experiences between participants and one or more of interactive nodes. At each interactive node there is a main display that shows shared information to each of the participants and to other viewers. Each of the participants also uses a personal controller such as a smart phone which has a personal display. Information that is specific to the participant can be displayed on the personal controller.

The system for operating a match-up game includes a display unit having a plurality of player screen regions configured to display game screens a first input unit configured to receive an input from a first player a second input unit configured to receive an input from a second player a first air outlet configured to discharge air to the first player a second air outlet configured to discharge air to the second player; a control unit configured to control the display unit to count a game time and change the game screens displayed on the player screen regions for each counted game time, and when receiving an input to the first input unit from the first player, control the second air outlet so as to discharge air corresponding to the received input. The system for operating a match-up game may increase a player's sense of immersion.

A portable, handheld game console includes a main body incorporating a touch-sensitive display screen and a variety of input devices. The input devices can include shoulder buttons located on a peripheral side surface of the main body, as well as input devices located on the main body adjacent the touch-sensitive display screen.
