Abstract: An information processing system, including: an input acquisition unit acquiring user input from a user associated with a predetermined display medium movable in a virtual space; a position control unit controlling a position of the predetermined display medium in the virtual space, on the basis of the user input; and an output processing unit outputting a user interface capable of generating the user input, the output processing unit switching the user interface from a first user interface to a second user interface when the predetermined display medium is moved from a first position to a second position in the virtual space, in which the output processing unit changes a switching mode from a first user interface to a second user interface, on the basis of a positional relationship between the first position and the second position in the virtual space.
