This　article　stemmed　from　practice　experience　of　being　a　professional　interior　designer.　A　number　of　questions　arose　mainly　concerning　the　role　of　the　interior　designer　in　relation　to　the　client.　As　the　relationship　between　client　and　designer　is　always　a　dynamic　one　that　changes　over　the　course　of　the　design　process,　this　article　focuses　primarily　on　implementing　communication　modes　to　enhance　the　design　process　and　achieve　the　design　goals.　As　Internet　has　been　broadly　employed　in　our　daily　lives　and　the　advancing　of　information　communication　technology,　inevitably,　communicational　applications　via　Internet　are　counted　as　a　useful　tool　to　replace　traditional　communication　ways　conducted　in　design　processes.　By　examining　existing　difficulties　of　communications　and　potentialities　for　the　future　design　process,　this　article　proposes　a　conceptual　prototype　of　Web-Based　Communication　Service　based　on　a　user-centered　design　to　enhance　communication　for　the　practice　of　interior　design.　©　2015　Taylor　&　Francis　Group,　London.
