“…Embodied museum agents are gaining much attention, and several such systems currently exist (Kopp et al, 2005;Lim et al, 2005). Museums are a particularly appropriate arena in which to have an agent that embodies culture, as tourists from many different cultures are often the visitors in these settings.…”

Conveyance and recognition of human emotion and affective expression is influenced by many factors, including culture. Within the user modeling field, it has become increasingly necessary to understand the role affect can play in personalizing interactive interfaces using embodied animated agents. However, little research within the computer science field aims at understanding cultural differences within this vein. Therefore, we conducted a study to evaluate if differences exist in the way various cultures perceive emotion from body posture. We used static posture images of affectively expressive avatars to conduct recognition experiments with subjects from three cultures. After analyzing the subjects' judgments using multivariate analysis, we grounded the identified differences into a set of low-level posture features. We then used Mixture Discriminant Analysis (MDA) and an unsupervised expectation maximization (EM) model to build separate cultural models for affective posture recognition. Our results could prove useful to aide designers in creating more effective affective avatars.

Experiments with Mobile Drama in an Instrumented Museum for Inducing Conversation in Small Groups

Small groups can have a better museum visit when that visit is both a social and an educational occasion. The unmediated discussion that often ensues during a shared cultural experience, especially when it is with a small group whose members already know each other, has been shown by ethnographers to be important for a more enriching experience. We present DRAMATRIC, a mobile presentation system that delivers hourlong dramas to small groups of museum visitors. DRAMATRIC continuously receives sensor data from the museum environment during a museum visit and analyzes group behavior from that data. On the basis of that analysis, DRAMATRIC delivers a series of dynamically coordinated dramatic scenes about exhibits that the group walks near, each designed to stimulate group discussion. Each drama presentation contains small, complementary differences in the narrative content heard by the different members of the group, leveraging the tension/release cycle of narrative to naturally lead visitors to fill in missing pieces in their own drama by interacting with their fellow group members. Using four specific techniques to produce these coordinated narrative variations, we describe two experiments: one in a neutral, nonmobile environment, and the other a controlled experiment with a full-scale drama in an actual museum. The first experiment tests the hypothesis that narrative differences will lead to increased conversation compared to hearing identical narratives, whereas the second experiment tests whether switching from presenting a drama using one technique to using another technique for the subsequent drama will result in increased conversation. The first experiment shows that hearing coordinated narrative variations can in fact lead to significantly increased conversation. The second experiment also serves as a framework for future studies that evaluate strategies for similar adaptive systems.

“…Perhaps the most common examples are of guides (M. Y. Lim, Aylett, & Jones, 2005;Roussou, 2001) and routeplanners (Costantini, Mostarda, Tocchio, & Tsintza, 2008;Papagiannakis & MagnenatThalmann, 2007;Song, Elias, Martinovic, Mueller-Wittig, & Chan, 2004). In many other projects intelligent agents are employed to create a sense of inhabitation and enact crowd simulations (Bogdanovych et al, 2009;C.-K. Lim, Cani, Galvane, Pettre, & Zawawi, 2013;Sequeira, Morgado, & Pires, 2014;Sequeira & Morgado, 2013).…”
