2009 - 2010
In our group, we designed and implemented a virtual agent capable of providing customers in a 3D online shop with advice. Based on a product knowledge base, a conversation model and a model of the shop, the agent communicated with the customer through text based dialogues and lead the customer through the virtual world, using gestures to show products. A controlled empirical evaluation study showed that customers in this shop generally followed the counseling of the agent and bought more suitable products. Also, a considerable number of the participants in the study expressed that they liked the principle of sales agents in virtual 3D online shops and considered our agent helpful.
