Overview
If Looks Could Kill is a first-person shooter game developed for Multimodal Interaction and Interfaces course that utilizes eye tracking to move the in-game crosshair. The game comes in two phases. In phase one, the player will be given a description of a man they have to follow. In phase two, the player have to determine the evil mayor to defeat.
The game is part of a research-through-design project that aims to understand the impact of gaze tracker in video games, especially for first-person shooter (FPS) games. We first researched related studies regarding gaze tracker implementation in video games. From the research, we managed to determine how should we implement the gaze tracking in our game, which was to control the camera and crosshair with gaze.
The game was developed in Unity, with my main contributions focusing on shader and post-processing development. In addition to Unity, I played a role in the research conducted before the development phase. Once the game was completed, we conducted a user study using the Game Experience Questionnaire (GEQ) to measure the impact of gaze tracing in FPS games.
From this research we found that our participants had difficulties with aiming and turning the camera in a smooth and fast manner. We also found that gaze tracking can provide high immersion, as the participants did not consider said difficulties to be a hindrance to be fully occupied in the game.
