摘要：Electrical tests involve high risk; therefore utility companies require highly qualified electricians and efficient training. Recently, training for electrical tests has been supported by virtual reality systems; nonetheless, these training systems are not yet adaptive. We propose a b-learning model to support adaptive and distance training. The adaptation is based on a representation of the knowledge and affect of the trainee. One of the main components is an animated pedagogical agent who guides trainees and provides instruction. The agent deploys different facial expressions conveying emotion and empathy to trainees. We incorporated these constructs into the learning model aiming to achieve credibility, social interaction, and user engagement, and thus improve learning. To develop the agent, we included some of the basic characteristics of electricians: work uniform and safety gear, such as helmets, gloves, and glasses, among other features. We believe that by representing the tutor as an electrician, the training environment will be better accepted by operators. The focus of this paper is a study that we conducted to gather knowledge about the expressivity and appearance of the animated agent. The participants evaluated the facial expressions of the agent and stated their point of view regarding the incorporation of the animated agent into the training system. The gathered knowledge is being used to enhance the animated agent before completing its integration to the training environment.
