| summary | Postures, facial expressions or other behaviors conveyinformation about other’s attitude, emotion, or intention. On the other hand,studying how observers could perceive, interpret and react to these reliablecues is of interest. Through this talk I will show two kinds of interaction thatcould be performed between a human participant and a virtual agent.
First, I will explain the interest in using virtualagent to better understand how clinicians, as common people, perceive and judgeother’s pain experience. Individuals, independently of their effective languageor social skills, can be challenged to describe the complexities of painexperience in a direct and representative manner. Since individuals in painexhibit typical behaviors (e.g., Prkachin et al., 2002; Hodges & Tucker,2011; Lariviere et al., 2002), nonverbal pain behaviors provide relevant cues tobetter estimate other’s (patient’s) pain intensity and related disability. A virtualagent could then provide fine-grained and standard pain cues, easy tomanipulate. It helps to identify changes in observer’s judgment across theintensity or characteristics of the pain behavior exhibited. In such cases, thevirtual agent serves fundamental purposes, aiming to draw or extend theoreticalframeworks.
Secondly in this talk I wonder if we could (inter)actin a natural fashion with a virtual agent. The concept of joint attention will illustratethis purpose. The use of another person’s eye gaze as a cue to shift attentionis a fundamental skill in social interactions (for a review, see Frischen, etal., 2007). The other person’s gaze triggers reflexive, automatic attentionshift in the corresponding direction in the observer. When attention isdirected toward a particular location, the visual processing of targets in thatlocation is facilitated, resulting in faster reaction times (RTs) to detect or discriminatetargets at that location than in locations that are not gaze-cued (the gaze congruityeffect or gaze-cueing effect, e.g., Bayliss et al., 2005). This automaticpropensity to orient to the same location where other people are looking is themain way of establishing joint attention with others (Emery, 2000). I will thusdescribe studies exploring whether, and under which condition, this attentionalprocesses is working when people interact with a virtual agent. |
