Entertainment Feature of a Computer Game Using a Biological Signal to Realize a Battle with Oneself

A novel computer game was developed in which a player challenges him- or herself using the skin conductance response to make the player aware of his or her own agitation. This game was developed as a paradoxical system in which their desire to win makes it more difficult to win. This type of game was found to have the following characteristics. First, players find uncontrollable themselves due to viewing their biological signals. In this situation, a kind of self-reference system is constructed. Second, the environments changed how the game was enjoyed. Third, the game system reveals differences of context between player and observer. From these characteristics, it is thought that the use of biological signals is attractive for entertainment computing.
