1. An information processing apparatus, comprising: a central processing unit (CPU); and a memory storing instructions for execution by the CPU, wherein the CPU is configured to: set a contribution action for a first user of a plurality of users, based on a history of operation information of the first user, wherein the operation information is associated with operation inputs of the first user on a contribution degree notification screen; detect the contribution action representing a contribution from the first user to a target; assign a contribution degree to the first user based on the contribution action; set a virtual distance between the first user and the target based on an integrated value of the contribution degree of the first user; control the contribution degree notification screen to concurrently display the target at a first position and the first user at a second position, wherein the first position is at the set virtual distance from the second position, wherein the set virtual distance, between the first user and the target, decreases based on an increase in the integrated value of the contribution degree of the first user; and control the contribution degree notification screen to display a change in the set virtual distance between the first user and the target.
