In this paper, we present an interactive mannequin for persuading bypassing customers to extend the perceived time they stay in front of a shop window. The mannequin was designed and prototyped to be seamlessly integrated into a real shop window, constituting an ambient persuasion interface. The design concept of our virtual mannequin is based on actual "real world" mannequins. Based on implicit input from the customers, the mannequin reacts on their presence by looking into their direction. We implemented a prototype of the persuasive interactive mannequin (PIM) as a 3D model, visualized on a large LCD screen and deployed it in a retail store within a shopping mall. The results from a three days field study of this deployment are presented and discussed. The study results give insights about the persuasive effect of the mannequin as well as implications for the user centered design of interactive agents in the context of shopping.

In this paper we explore a fundamental characteristic of Ambient Persuasive Technology: Can it persuade the user without receiving the user's conscious attention? In a task consisting of 90 trials, participants had to indicate which of three household appliances uses the lowest average amount of energy. After each choice, participants in the supraliminal feedback condition received feedback about the correctness of their choice through presentation of a smiling or a sad face for 150 ms. Participants in the subliminal feedback condition received identical feedback, but the faces were presented only for 25 ms, which prohibited conscious perception of these stimuli. The final third of the participants received no feedback. In the next task, participants rated the energy consumption of all presented appliances. Results indicated that supraliminal feedback and subliminal feedback both led to more correct energy consumption ratings as compared to receiving no feedback. Implications are discussed.

“…In particular, recent research has concentrated on their use in situations where relationships are important in human-human interaction. For example, teaching (Burleson and Picard, 2004;Maldonado et al, 2005), exercise and nutritional advisors (Bickmore and Picard, 2005;Creed, 2006;Mazzotta and De Rosis, 2006), and therapy (Grolleman et al, 2006). Embodied agents have also been used in computer games for a number of years and are now widely used in Massive Multiplayer Online Games (MMOGs) like Second Life (Second Life, 2007) and There.com (There.Com, 2007).…”

Psychological responses to simulated displays of mismatched emotional expressions

Embodied agents are often designed with the ability to simulate human emotion. This paper investigates the psychological impact of simulated emotional expressions on computer users with a particular emphasis on how mismatched facial and audio expressions are perceived (e.g. a happy face with a concerned voice). In a within-subjects repeated measures experiment (N = 68), mismatched animations were perceived as more engaging, warm, concerned and happy when a happy or warm face was in the animation (as opposed to a neutral or concerned face) and when a happy or warm voice was in the animation (as opposed to a neutral or concerned voice). The results appear to follow cognitive dissonance theory as subjects attempted to make mismatched expressions consistent on both the visual and audio dimensions of animations, resulting in confused perceptions of the emotional expressions. Design implications for affective embodied agents are discussed and future research areas identified.
