Abstract:

Digital ads often display video content in which immobile products are presented as if they are moving spontaneously. Six studies demonstrate a speed-based scaling effect, such that consumers estimate the size of an immobile product to be smaller when it is animated to move faster in videos, due to the inverse size–speed association they have learned from the domain of animate agents (e.g., animals, humans). Supporting a cross-domain knowledge transfer model of learned size–speed association, this speed-based scaling effect is (1) reduced when consumers perceive a product’s movement pattern as

Abstract:

Many studies on human–computer interaction have demonstrated that the visual appearance of an agent or a robot significantly influences people’s perceptions and behaviors. Several studies on the appearance of agents/robots have concluded that consistency between expectations from an agent’s or a robot’s appearance and performances was an important factor to the continuous use of these agents/robots. This is because users would stop interacting with the agents/robots when predictions are not met by actual experiences. However, previous studies mainly focused on the consistency between an initia

Abstract:

Animated agents that act and speak as attendants to guests on shopping web sites are becoming increasingly popular. Inspired by this development, we propose a new method of presentation using a humanoid robot. Humanoid presentations are effective in a real environment because they can move and look around at the audience similar to a human presenter. We developed a simple script language for multimodal presentations by a humanoid robot called MPML-HR, which is a descendant of the Multimodal Presentation Markup Language (MPML) originally developed for animated agents. MPML-HR allows many non-sp

Abstract:

Research on animated pedagogical agents (agents) is viewed as a very positive attempt to introduce more pedagogical support and motivational elements into multi-media instruction. Yet, existing empirical studies that examine the learning benefits of agents have had very mixed results, largely due to the way that they are designed. This article will suggest five design principles for future research on the impact of agents on learning and motivation including: 1) The Balanced Separation Principle describes need for adequate controls that tease out the specific type of learning and/or motivation

Abstract. Previous research found that cohesion manipulations (e.g., splitting an object into two parts) may have deleterious effects on infants’ object representation. The present study investigated whether the cohesion principle is relevant only when assessing the continuity of inanimate objects, or whether it is equally fundamental for the perception and representation of animate agents. In two experiments, we assessed 8-month-old infants’ tracking behavior in events in which an agent (an animated snail) was either split in half, fused together, or simply changed its shape.

Abstract:

Animated pedagogical agents are lifelike virtual characters designed to augment learning. A review of developmental psychology literature led to the hypothesis that the temporal contingency of such agents would promote human learning. We developed a Pedagogical Agent with Gaze Interaction (PAGI), an experimental animated pedagogical agent that engages in gaze interaction with students. In this study, university students learned words of a foreign language, with temporally contingent PAGI (live group) or recorded version of PAGI (recorded group), which played pre-recorded sequences from live se

Abstract:

Pedagogical agents are animated characters embedded within an e-learning environment to facilitate learning. With the growing understanding of the complex interplay between emotions and cognition, there is a need to design agents that can provide believable simulated emotional interactions with the learner. Best practices from the animation industry could be used to improve the believability of the agents. A well-known best practice is that the movements of limbs/torso/head play the most important role in conveying the character's emotion, followed by eyes/face and lip sync, respectively, in a

Three-dimensional facial animation has been extensively studied, but the achievement of realistic, human-like performance has not yet been decided. This article discusses various approaches for generating animated facial expressions controlled by speech. Combining the considered approaches for both facial animation, and the identification of emotions and the creation of micro-facial expressions in one system, we get a solution suitable for tasks such as game video, avatars of virtual reality or any scenario in which a speaker, speech or language is not known in advance.

The article traces the ways that dominant conceptualisations of children as ‘innocent victims’ has animated an agenda that focuses primarily upon their victimisation that, in turn, reinforces the legitimacy of the protection ethic.
