So　far　the　research　on　Ambient　Intelligence　(AmI)　has　been　lunched　in　Europe　and　Human-Computer　Interaction　becomes　an　important　technical　aspect　of　it.　AmI　is　the　integration　of　ubiquitous　computing,　ubiquitous　communications　and　the　application　of　user　interface,　and　its　goal　is　to　design　and　realize　the　brand-new　intelligent,　personalized　and　connective　systems　or　services.　In　this　paper,　we　put　forward　an　experimental　system,　which　incarnate　the　essential　characteristics　of　Ambient　Intelligence.　The　architecture　and　context-aware　mechanisms　of　this　system　is　discussed　briefly　and　the　detail　of　some　Human-Computer-Interaction　techniques　is　expounded.　With　the　building　of　research　platform,　some　Human-Computer-Interaction　techniques　are　worthy　of　further　study　in　the　future.
