We present CookieFlavors, a TUI prototyping tool that provides a set of physical input primitives realized by coin-size Bluetooth wireless sensors named Cookie. Developers can attach CookieFlavors on any physical objects and examine the suitability of tangible input in a TUI prototype phase. We have built a map viewer application and projected it in an experimental room that contains various physical objects and several CookieFlavors. We asked the focus group to manipulate the map viewer application by augmenting CookieFlavors into physical objects. In this paper we present the interesting result of their perception and activities regarding this intuitive TUI, CookieFlavors.
