The HNS-VAUI was implemented with MMDAgent toolkit. A user can operate appliances and services interactively through dialog with a virtual agent in a screen. However, the previous prototype heavily depends on MMDAgent, which causes a tight coupling between HNS operations and agent behaviors, and poor capability of using external information.To cope with the problem, this paper proposes a service-oriented framework that allows the HNS-VAUI to provide richer interaction. Specifically, the authors decompose the tightly-coupled system into two separate services: MMC Service and MSM service. The MMC service concentrates on controlling detailed behaviors of a virtual agent, whereas the MSM service defines logic of HNS operations and dialog with the agent with richer state machines. The two services are loosely coupled to enable more flexible and sophisticated dialog in the HNS-VAUI. The proposed framework is implemented in a real HNS environment. The authors also conduct a case study with practical service scenarios, to demonstrate effectiveness of the proposed framework.<\/p>","DOI":"10.4018\/ijsi.2015040103","type":"journal-article","created":{"date-parts":[[2015,1,30]],"date-time":"2015-01-30T14:26:06Z","timestamp":1422627966000},"page":"13-23","source":"Crossref","is-referenced-by-count":5,"title":["Virtual Agent as a User Interface for Home Network System"],"prefix":"10.4018","volume":"3","author":[{"given":"Hiroyasu","family":"Horiuchi","sequence":"first","affiliation":[{"name":"Graduate School of System Informatics, Kobe University, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sachio","family":"Saiki","sequence":"additional","affiliation":[{"name":"Graduate School of System Informatics, Kobe University, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinsuke","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Graduate School of System Informatics, Kobe University, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahide","family":"Namamura","sequence":"additional","affiliation":[{"name":"Graduate School of System Informatics, Kobe University, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"ijsi.2015040103-0","unstructured":"Axis.apache.org.
