<p>PROBLEM TO BE SOLVED: To prevent an uneasy feeling that already displayed object data might disappear from being given to a user, even when object data received from a drawing device is displayed.SOLUTION: A display terminal device for displaying an object arranged in a virtual space on a display unit comprises an identification information generation unit, a transmission unit, a reception unit, a storage unit, and a display control unit. The identification information generation unit generates object identification information including user identification information. The transmission unit transmits an object which is input by a user and object identification information thereof to a drawing device. The reception unit receives the object and the object identification information thereof from the drawing device. The storage unit stores the object and the object identification information to be received from the drawing device during a period until the reception unit receives the object transmitted by the transmission unit. The display control unit updates a display screen on the display unit so as to display the object received by the reception unit.</p> |
