Computer-readable storage medium having stored information processing program thereon, and information processing apparatus

An information processing apparatus comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory and configured to perform features comprising:
• sequentially obtaining, from a gravity center position detection device for detecting the gravity center position of a user, gravity center position data indicative of the gravity center position of the user,
• detecting a variation range of the gravity center position of the user during a predetermined period to the current time, based on previously obtained gravity center position data;
• and
• executing a predetermined information process based on a relative position of a gravity center position, indicated by a latest obtained gravity center position data, with respect to the detected variation range.
