INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD, AND PROGRAM

Disclosed is an information processing system that includes processing circuitry configured to dynamically change a setting value of a first control parameter or a second control parameter, the first control parameter being for controlling proximation distance or collision among a plurality of virtual reality mediums in a three-dimensional (3D) virtual space, and the second control parameter being for controlling a position travelable by the plurality of virtual reality mediums in the 3D virtual space. The processing circuitry is further configured to control, in a case in which the setting value is changed, a position or an orientation of the plurality of the virtual reality mediums based on the setting value.
