Visual Attention and Reaction Times in FPS Games

Sammanfattning: Visual cues are a technique used for the purposes of guiding a viewer towards points of interest. Most commonly this is done with the use of color and contrast to make objects stick out more from its environment. Within the context of video games, visual cues are implemented to guide player actions in otherwise complex scenarios. Due to the steady increase of high-fidelity graphics in video games, visual cues are becoming more important for players so that visual clarity can still be maintained. In the video games analyzed in this thesis this is primarily done by adding a glowing outline (highlight) around the object or entity that the game designers want the player to interact with. Thus, this thesis attempts to explore two different qualities of visual cues: color and glow intensity, to see their effects on player performance and experience. To do this, an experiment was conducted in a scaled-down version of an FPS game with the purpose of testing these different qualities in four different scenarios and how they may influence both reaction time and player satisfaction. The results from this study indicate that neither of the tested qualities had any significant impact on a participant’s ability to complete their task. On the other hand: color had a big effect on player experience where one color, purple, was deemed irritating by most participants. Finally, the differences in glow intensity went unnoticed in most of the tested scenarios which points towards color being the more important quality of the ones tested in this study.
