Abstract

Superior anticipation and decision-making are characteristics of successful team athletes [1].
They are capable of more accurate predictions on future events, in particular based on superior
recognition of postural orientation of opponents and faster pattern and structure recognition in
decisive situations [2]. To analyze and hence quantify such perceptual processes, eye-tracking has
been used as a method to examine the gaze behavior of athletes. Current research shows that
state-of-the-art mobile eye-tracking glasses are not fully reliable because of different disruptive
factors like bad light conditions or missing tracking data caused by fast movements [3]. Therefore,
different technology approaches should be explored, to compensate these issues and provide a
reliable alternative to current mobile eye-tracking devices.
Recent advances in virtual reality (VR) hardware technology have brought this immersive medium
to a broad acceptance with a major interest also coming from the area of healthcare and sports
[5]. VR provides immersive computer-simulated environments to the user by enabling depth
perception based on stereoscopic vision. In sports, this can be applied to assess and train athletes
under real-world conditions and reduce injury risks at the same time. Especially for the assessment
and training of mental strength and cognitive skills of athletes, researchers could show that VR is
a promising tool [5].
Applying eye-tracking for VR sport simulations-based assessment of athletes yields great potential
due to several reasons. First, computer-generated environments are fully controllable and hence
undesired effects and distractors can be avoided; Second, the reproducibility of the simulation is
extremely high, meaning that every athlete experiences the same conditions which facilitates a
valid comparison of results; Third, HMD integrated eye-tracking systems are less disruptive to
negative influencing factors like changing light conditions and thus are expected to ensure data
reliability; Fourth, a more sophisticated mapping of the eye-tracking data can be achieved, since
every object within the virtual environment is known and can be related to the gaze behavior of
an athlete.
In existing studies, the gaze behaviors of athletes were analyzed using video simulation and real
world in-situ conditions [3,7]. Results show that the gaze behavior varies significantly between
video based and real word conditions. To our best of knowledge there is no research that
investigates the influence of VR sport simulations on gaze behavior of athletes.
In this thesis the gaze behavior of soccer players in a VR sports environment will be evaluated and
analyzed using an HMD-integrated eye-tracking system. Therefore, a realistic VR soccer simulation
will be designed and implemented. Further at least eight athletes will be evaluated regarding their
gaze behavior while experiencing the VE. Finally, the results of the study will be compared to
results of previous studies.
