Mobile embodied conversational agent for task specific applications

In the recent years major efforts have been made to promote the use of virtual assistants on mobile devices. But in most cases these assistants can only manage a limited and predetermined set of applications. Other limitation that makes difficult the adoption of this technology is the need for a data connection. Thus, this paper introduces the use of an Embodied Conversational Agent (ECA) as an assistant for task-specific applications. The proposed ECA is based on open-source components and runs entirely on the mobile device. The system design was validated by conducting tests to measure the latency and energy consumption.
