Embodiesd Conversation Agents (ECSs) Essay - 925 Words

The purpose of this section is to provide the reader with a brief insight on Embodied Conversational agents ( ECAs). This chapter is organized into three section. The First section gives a general overview about ECAs through literature review. The second Section explores some concerns related to the use of agent in different contexts. The third section considers the design decision’s perspectives of virtual agents Embodied Conversational Agents ( ECAs) Embodied agents are computer interfaces which exhibit human-like behaviors (e.g. non-verbal behavior, audio-visual speech, or personality and emotion) [29]. The embodied interface is presented as human face by using state-of-art technology such as realistic three dimensional (3D) facial†¦show more content†¦First, the major technical issue is the poor quality of realistic looking virtual humans with a lack of emotional intelligence such as empathy, facial expression and gesture. The existing embodied agents’ grap hics are often poor, also monotone voice is widely used by this type of interface for communication purpose [30]. Therefore, agents’ ability to have an effective interaction will be limited due to inadequate language and emotional capabilities. Second, the social issue that can arise from using embodied agents interfaces is the resistance to change. Social barriers such as culture can create resistance to change in a way that users will not accept the idea of using embodied interfaces and interacting with a virtual human. Because of that, these issues may negatively impacts the effectiveness of embodied agents as well as limit interfaces to become commonly acceptable in the eyes of society. During the last decade, considerable amount of research has been conducted to have a clear idea about how people interact with Embodied Conversational Agents (ECA) and to understand the potential benefits of using embodied agents in the future. Agent Design Decision’s dimensions: According to our researches, we found that the design decision of an embodied conversational agent can be taken based on several
