Experiments of Entertainment Applications of a Virtual World System for Mobile Phones

Using a virtual world system for GPS-phones, we have developed a small RPG-like game to give information to tourists. Comparing with other virtual systems for mobile terminals, the cost of our system is much lower because only phones on the current market are required but no additional devices are needed. The game follows a Japanese famous tale and a player plays as the hero. We recruited twenty subjects and they played it 35 minutes in average. Through evaluation sessions of the system, we have found that the system is highly evaluated as an entertainment system.
