The present concepts relate to devices that can approximate virtual objects when touched by a user. One example device can include a location assembly configured to sense a location of the device on a surface and configured to move the robotic device on the surface and a shape assembly secured to the location assembly and configured to adjust a height and a pitch of an upper surface of the robotic device.

A video surveillance system includes a plurality of video surveillance cameras each for producing a corresponding video stream, a server configured to receive and store the video streams, and a first control room having a video wall. The video wall may be operatively coupled to the server and may be configured to concurrently display two or more of the video streams from two or more of the plurality of video surveillance cameras in a first arrangement. The video surveillance system may further include a remote virtual reality headset with a display and a virtual reality controller operatively coupled to the virtual reality headset and the server. The virtual reality controller may be configured to receive the same two or more video streams that are displayed on the video wall in the first control room and display them in the virtual reality headset.

Embodiments of the present invention describe streaming media transmission methods and apparatus applied to a virtual reality technology. A method for streaming media transmissions may include sending a media information obtaining request to a server, where the media information obtaining request includes client capability information and auxiliary information, the client capability information indicates that the client supports reception of data pushed by the server, and the auxiliary information indicates an attribute that the client supports virtual reality presentation. The method may also include receiving a media presentation description and media data, where the media presentation description and the media data are sent by the server after the server responds to the media information obtaining request. According to the streaming media transmission methods and apparatus applied to a virtual reality technology in the embodiments of the present invention, a transmission delay can be reduced, and transmission efficiency can be improved.
