Is there a difference in visual search patterns between watching video clips of fencers on a computer screen and reacting on them on a life-sized screen?

Abstract

To compare the visual attention of multiple subjects in a sports situation, an identical stimulus has to be presented, which is often only possible by using video stimuli. Therefore, reacting on video clips, projected on a large screen, seems to approach a real-life situation the most. Reacting while watching a projection screen implies that a Head-mounted Eye-tracking Device (HED) has to be used, implicating time consuming data analysis. When participants only have to watch the video, a Remote Eye-tracking Device (RED) can be used. With these devices, automated data analysis ensures less time loss. However, gaze behavior while watching videos on a computer screen might differ from gaze behavior when reacting on them on a life-sized projection screen. In current experiment gaze behavior of elite fencers was examined in three different conditions.

Gaze behaviour of experienced and novice beach lifeguards – An exploratory in situ study

“…Although video‐based studies mimic real‐life gaze behaviour (Underwood, Crundall, & Chapman, 2011), gaze behaviour in laboratories has often been shown to differ from gaze behaviour in situ (Dicks, Button, & Davids, 2010; Foulsham, Walker, & Kingstone, 2011; Zeuwts, Debuyck, Vansteenkiste, & Lenoir, 2013). Therefore, whereas video based studies have already provided valuable insights into the visual attention of lifeguards (and the various factors affecting it), these studies might not have reflected the gaze behaviour that lifeguards adopt in a natural setting.…”
