The multi-user information sharing space is apt to get information overload. Therefore, I targeted realizing the efficient information sharing space that reduce complicatedness even if include many information. I proposed user interest guidance and user preference affordance with visually insistency / repression visualization effects.As research results, I proposed as follows: (1) the user interest guidance method to differentiate the information visually with decorating space by ambient intelligence technique without giving a user a sense of incongruity as much as possible; (2) the high-speed processing and high-accuracy indoor position estimation method using GPGPU with fiducial marker; and (3) ad-hoc communication method without the wireless communication bandwidth using markers animation.
