Recent studies in Virtual Reality highlighted the importance of avoiding Breaks in Presence that occur when experiment participants alternate between the virtual and physical environment to fill in questionnaires or interact with the evaluator. In this paper, we report on a within-groups experiment comparing three means of communication between the evaluator and the immersed participants in user studies in VR: Voice-Speaker, Video-Screen, and a 3D-Avatar. Immersed participants (N=38) completed three sets of tasks and were observed and then interviewed through these three methods successively. Our findings reveal no significant difference in user performance between the methods. There were, however, significant differences in how the methods were perceived by the participants, with Video-Screen, considered the most effective communication method. In contrast, the 3D-Avatar method was considered as the most “fun” and the users’ “favorite”, along with the Video-Screen. The Voice-Speaker was thought to be the least distracting yet impersonal, and the least favorite.
