Seeing Eye to I? The Influence of Self-Video Display Size on Visual Attention and Collaborative Performance in Peer-to-Peer Video Chat

Abstract

This thesis examines the influence of self-video size in video chat conversations on visual attention, collaborative performance, grounding, comfort and distraction during a brainstorming task. Twenty pairs of female university students were randomly assigned to either a large or small self-video condition. Two eye tracking systems were used to simultaneously record pairs of participants' gaze across 4 areas-of-interest spanning a 15-minute task. Participants with larger self-video gazed at themselves longer but did not spend a significantly different percentage of the conversation gazing at their partner. Participants sufficiently estimated how long they looked at each other, but significantly overestimated how long they, and their partners, gazed at their own self-video. A majority of participants found their self-video to be comforting, and participants with larger displays found it to be more distracting than those with smaller displays. Over a third of participants would prefer to chat without their self-video visible
