A robotic mount is configured to move an entertainment element such as a video display, a video projector, a video projector screen or a camera. The robotic mount is moveable in multiple degrees of freedom, whereby the associated entertainment element is moveable in three-dimensional space. In one embodiment, a system of entertainment elements are made to move and operate in synchronicity with each other, such as to move a single camera via multiple robotic mounts to one or more positions or along one or more paths.

A motorized, rotatable treadmill and a system for creating the illusion of user movement while the user is stationary with respect to an environment as the user walks or otherwise moves on an endless track of the treadmill. The user can then travel an unlimited distance in unlimited directions while remaining stationary in physical location. The speed of the treadmill is precisely controlled and/or precisely matched with movement of a camera and a real-world speed of movement of the user and the distance the user travels on the belt to create the illusion of movement of the person being filmed. When the treadmill is provided within an LED virtual film set or green screen set, background imagery is added to further supplement the movement in a selected environment.

An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

A motion system for moving objects in a space, e.g., for moving virtual reality (VR) participants about space used to provide a VR environment. The system includes a controller and a position monitoring assembly. The system has a modular floor including a plurality of tile assemblies defining a support surface for a first and a second object. Each of the tile assemblies includes: (a) a planar tile with an upper surface for supporting the first and second objects; and (b) a drive system. The drive system includes a vibration-inducing assembly operable to oscillate the planar tile in a horizontal plane and further includes a preferential friction assembly operable to selectively reduce friction between the upper surface and any supported object. The controller generates control signals, based on position information, to independently control the tile assemblies of the modular floor to move the first and second objects on the support surface.

A method to identify a targeted object based on eye tracking and gesture recognition. The method is enacted in a compute system controlled by a user and operatively coupled to a machine vision system. In this method, the compute system receives, from the machine vision system, video imaging a head and pointer of the user. Based on the video, the compute system computes a geometric line of sight of the user, which is partly occluded by the pointer. Then, with reference to position data for one or more objects, the compute system identifies the targeted object, situated along the geometric line of sight.

A method for compensating drift of a motion direction sensor system for measuring a motion direction of a user in a VR system includes receiving a measured viewing direction of the user from a viewing direction sensor system for measuring a viewing direction at a measurement time, receiving a measured motion direction of the user from the motion direction sensor system for measuring a motion direction at the same measurement time, and calculating a drift compensation from the difference between the measured viewing direction of the user and the measured motion direction of the user so that a drift compensated motion direction of the user can be determined by adding the calculated drift compensation to a subsequently measured motion direction of the user. One embodiment includes a computer program product and a device configured to perform the method.

An omnidirectional treadmill environment simulator is disclosed. The omnidirectional treadmill environment simulator includes a circular simulator stage area, a plurality of transport mechanisms that maintain an object at or near the center of a circular simulator stage area and at least one processor. The processor is configured to collect position data of the object and process the position data to control the transport mechanisms. Also included is a receiver for receiving data from a remote location and a terrain analysis computer for processing the data received from the remote location. The terrain analysis computer collects the data received from the remote location to form an accurate simulation of an upcoming condition at the remote location. The omnidirectional treadmill environment simulator includes a transmitter for transmitting the position data to a remote location.

The disclosure provides methods and systems for warning a user of a head mounted display that the user approaches an edge of field of view of a camera or one or more tangible obstacles. The warning includes presenting audio and/or displayable messages to the user, or moving the display(s) of the head mounted displays away of the user's eyes. The determination that the user approaches the edge of scene or a tangible obstacle is made by dynamically tracking motions of the users through analysis of images and/or depth data obtained from image sensor(s) and/or depth sensor(s) secured to either the head mounted display, arranged outside of the scene and not secured to the head mounted display, or a combination of both.

The disclosed technology relates to a system for providing virtual exercise place, which displays a user-selected virtual exercise place, and shares the display of the selected virtual exercise place with other users in real time or at a different time in order to exercise together. The system comprises an image information database in which location-based image data related to a virtual exercise place is stored; and an image data controller which selects from the image information database the location-based image data related to the virtual exercise place received from a terminal, transmits them to the terminal, displays on the terminal the exercise place image data corresponding to an exercise start location received from the terminal, receives an exercise distance information calculated by fitness equipment, and displays on the terminal the exercise place image data corresponding to a location moved by the exercise distance from the exercise start location.

A method, system, computer readable media and cloud systems are provided for adjusting image data presented in a head mounted display (HMD). One method includes executing a virtual reality (VR) session for an HMD user. The VR session is configured to present image data to a display of the HMD. The image data is for a VR environment that includes a VR user controlled by the HMD user. The method further includes adjusting the image data presented on the display of the HMD with the cadence profile when the VR user is moved in the VR environment by the HMD user. The adjusting causes a movement of a camera view for the image data that is for the VR environment as presented on the display of the HMD. In some examples, the cadence profile substantially replicates a rhythmic movement of a person while moving in a real world environment.
