Phone control and presence in virtual reality

In one general aspect, a method can include receiving, by a first computing device from a virtual reality (VR) headset, data indicative of a position of a second computing device, rendering, by the first computing device, an aspect of the second computing device for inclusion in a VR space based on the position of the second computing device, and integrating the rendered aspect of the second computing device with content for display as integrated content in the VR space. The method can further include providing the integrated content to the VR headset for display on a screen included in the VR headset, receiving data indicative of an interaction of a user with the second computing device, and based on the received data indicative of the interaction of the user with the second computing device, altering the content for display as integrated content in the VR space.

Virtual reality keyboard system and method

A system and method implement a virtual reality (VR) keyboard. The VR keyboard system and method receive a VR glove position, generate a corresponding key code from the VR glove position using a predetermined mapping, and send the key code to an application program as a key input corresponding to a keyboard and/or keypad entrap of data and/or a command. The system and method also generate a display representing the key input based in on the VR glove position. The display of the key input may include, but is to limited to, a displayed depressed key in a VR headset of a VR representation of a VR keyboard indicating the key input. The system and method implementing a virtual reality keyboard addresses and solves numerous difficulties of physical and/or hardware-based input devices and provides many diverse advantages in use and applications.

Methods and apparatus to provide user a somatosensory experience for thrill seeking jumping like activities

A method of providing user somatosensory experience for “thrill seeking jumping like activities” (for purposes such as but not limited to training, game, or entertainment) involves:Providing means for changing elevation of user that rapid enough for user to feel the difference of gravity feeling or “G force” with feelings of user under stationary situation, wherein the facing direction relative to the direction of movement and/or pose of the user can be changed, and the speed of elevation change provide by the means can be controlled/adjusted;While the user using the elevation changing means, using a computer-implemented virtual reality system to present to the user a virtual reality environment. The view point and/or direction changes in the virtual reality environment are consistent with the position changes and/or self motion of the user in the elevation changing means;So that the user experiences the virtual reality environment under a “variable gravity” condition or “G-Force” provided by the elevation changing means in a synchronized way, such “variable gravity” condition enhancing experience of the virtual reality environment. It is also possible for users to interact with the system by means such as game controller or gesture and etc, so that the output of the elevation means could be affected/changed by user input.

Sensory stimulus management in head mounted display

Methods, systems, and computer programs are presented for managing the sensory stimulus generated by a head mounted display (HMD). One method includes an operation for identifying the game state of a game being executed for display on a head mounted display (HMD). Further, the method includes an operation for determining the game intensity value for the game state based on user intensity ratings obtained from user play of the game. The user intensity ratings represent the level of sensory stimulus presented to users during the user play of the game via the HMDs of the respective users. Further, the method includes an operation for presenting the game intensity value to the HMD for rendering during execution of the game.

Virtual reality and augmented reality functionality for mobile devices

Systems and methods improve virtual reality and augmented reality functionality for mobile devices using radio frequency (RF) signals transmitted by a tracked device and received at four or more spatially separated antennae. These antennae are connected, wirelessly or through wired connections, to a base station. Through RF signal time of arrival information acquired at the antennae, the base station can continuously determine accurate position information of the tracked device, without lighting or line of sight limitations experienced by camera and other optical systems. As the position of the RF-transmitting tracked device is registered within a virtual environment produced by an interactive software program in communication with (or part of) the base station, the virtual viewpoint of the tracked device is controlled to reflect the relative position and orientation of the tracked device with respect to the virtual environment produced by the software program and displayed on a view screen.

Interactive virtual reality performance theater entertainment system

Interactive virtual reality (VR) performance theater and environment system (100) in which plural participants enjoy an entertainment and/or educational experience. The performance is viewed by the participants through VR display devices such as a head mounted display (HMD), wherein both an immersive graphical environment and live and/or pre-recorded performers are viewed. The participants exert limited control over content and outcome of performance by hand held input devices (16) having a plurality of buttons (80), and/or voice communications, while viewing the performers who are mixed within the immersive VR environment. Inter- connected computers (102, video and audio processing devices (106, 108) are used. A network (104) interconnects the computers, participants, and live/pre-recorded performers for video, audio, and graphics transmission.

System for creating images, videos and sounds in an omnidimensional virtual environment from real scenes using a set of cameras and depth sensors, and playback of images, videos and sounds in three-dimensional virtual environments using a head-mounted display and a movement sensor

The invention relates to a system for creating images, videos and sounds in an omnidimensional virtual environment from real scenes using a set of cameras and depth sensors, and to the playback of images, videos and sounds in three-dimensional virtual environments using a head-mounted display and a movement sensor, for enabling the creation and playback of images, videos, sounds and films in a virtual omnidirectional environment from real scenes, allowing the spectator to control autonomously the position and direction of viewing during playback of the digital file, said system comprising a set of image positioning cameras (2) including image cameras (8) parallel to depth cameras (9), sound capture devices (13) and an inner computer (18). The images of the inner environment formed by the image positioning cameras can thus be captured and positioned in a virtual environment by a central computer (35). An example is the playback of a virtual environment file by a head-mounted display (14) coupled to a movement sensor (15) and a computer program for decoding the data received from the movement sensor (15) and transmitting the data to the sound emitter and to the user display screen, with a remote depth control (19) that allows the spectator to determine autonomously the desired virtual position during playback of the files, giving the user the sensation of total immersion in the virtual environment.
