Abstract: A system including a server arrangement and a programming interface in communication with external applications are provided. The server arrangement (i) acquires data from sensors, (ii) analyzes the data to determine at least one object of interest in a surveillance area, (iii) determines type of the at least one object of interest, one or more attributes associated with the at least one object of interest and a geospatial location of the at least one object of interest, (iv) estimates a state of the at least one object of interest based on the type of the at least one object, one or more attributes and the geospatial location; (v) compares the estimated state with a defined set of trigger conditions associated with surveillance area, and (vi) determines at least one action to be taken in the surveillance area based on the estimated state of the at least one object of interest matching with at least one of the trigger conditions.

Abstract: A system for providing a virtual environment on an at least one computing device. The system includes, a server arrangement to generate at least one first image associated with the virtual environment on at least one first virtual pattern, render visual orientations associated with the at least one first image on a render target, and generate at least one second image; and at least one computing device, communicably coupled with the server arrangement, to receive the at least one second image from the server arrangement, render each of the render targets of the at least one second image on an at least one second virtual pattern, determine the movement of head of the at least one user, and provide the virtual environment on a display arrangement based on a movement of head of the at least one user.

Abstract: There is provided a system for providing virtual reality content. The system includes a computing arrangement that is operable to execute image generating instructions to process the virtual reality content to generate image data, and a display arrangement that is operable to render the generated image data. The computing arrangement, when executing the image generating instructions, is operable to intercept drawing calls to one or more graphics libraries from application software that executes in operation in computing hardware of a user-wearable device of the system, or to intercept drawing calls from the one or more graphics libraries to a graphics driver of the display arrangement, wherein the user-wearable device includes the display arrangement; and to modulate camera and projection matrices of the drawing calls to create two images having a substantially hemi-spherical field of view for presentation to corresponding eyes of the user.

Abstract: A method for voice chat in a virtual environment includes receiving a plurality of audio streams corresponding to a plurality of avatars in the virtual environment, determining relative distances between the avatars in the virtual environment, calculating change in volumes of the audio streams, depending on the determined relative distances between the avatars, normalizing volumes of the audio streams depending on the calculated change in volumes, mixing the normalized audio streams to create a plurality of mixed audio streams, wherein one mixed audio stream corresponds to one avatar, and relaying the mixed audio streams to corresponding avatars.
