TLDR
Steve is an animated agent that helps students learn to perform physical, procedural tasks and can also monitor students while they practice tasks, providing assistance when needed.Abstract:
This paper describes Steve , an animated agent that helps students learn to perform physical , procedural tasks . The student and Steve cohabit a three - dimensional , simulated mock - up of the student's work environment . Steve can demonstrate how to perform tasks and can also monitor students while they practice tasks , providing assistance when needed . This paper describes Steve's architecture in detail , including perception , cognition , and motor control . The perception module monitors the state of the virtual world , maintains a coherent representation of it , and provides this information to the cognition and motor control modules . The cognition module interprets its perceptual input , chooses appropriate goals , constructs and executes plans to achieve those goals , and sends out motor commands . The motor control module implements these motor commands , controlling Steve's voice , locomotion , gaze , and gestures , allowing Steve to manipulate objects in the virtual world .read more

A domain-independent framework for modeling emotion
Jonathan Gratch,Stacy Marsella +1 more
TL;DR: It is shown how psychological theories of emotion shed light on the interaction between emotion and cognition, and thus can inform the design of human-like autonomous agents that must convey these core aspects of human behavior.

Virtual reality and mixed reality for virtual learning environments
TL;DR: Education uses of virtual learning environment concerned with issues of learning, training and entertainment show that VLE can be means of enhancing, motivating and stimulating learners' understanding of certain events, especially those for which the traditional notion of instructional learning have proven inappropriate or difficult.
