摘要: In this article, we propose the concept of meta-User Interface (meta-UI) as set functions (along with their user interfaces) that are necessary and sufficient to control evaluate state interactive ambient spaces. This is meta-, since it serves an umbrella beyond domain-dependent services support human activities in space. They User Interface-oriented role help users We present a dimension space classify, compare, contrast disparate research efforts area meta-UI's. then exploit generative power our design suggest directions for future research.
