Information processing system

An information processing system comprising three movable bodies, an information processing apparatus to control each of the three movable bodies, an information server to provide information to the information processing apparatus, a display device to display video in accordance with control from the information processing apparatus, and a remote controller to accept input of an instruction from a walking person,

• each of the three movable bodies comprising:
• a main body formed into a regular hexagon having six vertices when viewed from above, the main body enabling a walking person to ride on an upper surface of the main body;
• a pressure sensor to detect a pressure applied to the upper surface when the walking person rides on the upper surface;
• a plurality of wheels attached under the main body;
• a driving unit to supply a driving force to at least two wheels of the plurality of wheels;
• and
• a movable body controller to move the main body linearly in any direction and to rotate the main body by using a perpendicular line at each of the six vertices as an axis, by controlling the at least two wheels and the driving unit in accordance with control from the information processing apparatus,
• wherein each of the three movable bodies is adjacent to other two movable bodies so that a position at which three vertices selected each from the three movable bodies face each other is set as a central point,
• the information server comprising:
• a first memory to store a plurality of pieces of stereoscopic model data, each of the plurality of pieces of the stereoscopic model data being used to generate video data of stereoscopic video seen from a visual point of the walking person in a virtual space, and to store a program;
• and
• a first processor to select, by executing the program stored in the first memory, one piece of the stereoscopic model data from the plurality of pieces of the stereoscopic model data in accordance with the instruction the input of which is accepted by the remote controller,
• the information processing apparatus comprising:
• a second processor to execute a program;
• and
• a memory to store the program which, when executed by the processor, performs processes of,
• specifying an advancing direction and a walking speed of the walking person based on the pressure when the walking person walks,
• causing the three movable bodies to perform linear movement at the specified walking speed in an opposite direction to the specified advancing direction,
• specifying, as a target vertex, a vertex other than the three vertices which is able to be determined to lie in the specified advancing direction,
• causing at least one movable body of the three movable bodies to perform rotational movement so that a position of the target vertex is set as a new central point,
• specifying a position of the walking person in the virtual space based on the specified advancing direction and the specified walking speed,
• generating the video data of the stereoscopic video corresponding to the specified position by referring to the selected stereoscopic model data, and
• the display device displaying the stereoscopic video in accordance with the video data generated by the video control unit.
