Outline of Final Research Achievements

We implemented a method to adjust the AI of enemy characters in and out of the field of view by measuring the player's gaze in a wide field of view game contents such as VR. The target was a first-person shooter game, and we investigated the movements of the enemy characters from the latest FPS games and implemented them in the game.
The experimental results showed that when the frequency of attacks from enemies within the field of view was increased, even though the overall amount of attacks from enemies was the same, the perceived difficulty was higher, but the damage taken was lower. We found that this gives the player an experience that does not increase penalty damage unnecessarily while giving the player an experiential sense of the high difficulty of the game.
