INPUT DIRECTION DETERMINATION SYSTEM, TERMINAL SERVER, NETWORK SYSTEM, INFORMATION STORAGE MEDIUM, AND INPUT DIRECTION DETERMINATION METHOD

摘要

An input direction determination system includes an input direction determination section that determines the input direction based on a reference point and the indication position, and a reference point change section that determines whether or not to change the reference point based on an angle formed by a first direction that is determined by the reference point and an indication position at a first timing or a timing that precedes the first timing, and a second direction that is determined by the indication position at the first timing and an indication position at a second timing that follows the first timing, or an angle formed by connection lines that connect indication positions at different timings, and changes the reference point.
