We propose a novel capture and annotation system called TagTansu, which can easily capture pictures of clothes and add annotations to support creating a picture database of clothes. TagTansu consists of hook sensors and capture components attached inside the doors of a tansu (a wardrobe).Using TagTansu, users can easily take pictures of clothes and add annotations (e.g. types and weight of clothes) to the pictures just by hanging the clothes on a hook.

TagTansu mainly consists of several devices attached to the inside doors of a tansu (a wardrobe). We selected a wardrobe with double doors to utilize both door surfaces. As shown in figure 2, we attach hook sensors to one door and attach capture components -a camera, lights and an LCD- to the other door.

There are three hook sensors attached on a human shaped wood plate (Figure 3). We embedded a pressure sensor to each hook for detecting weight of clothes hung on the hook. Users can add different tags by hanging clothes on different hooks: a "tops" tag on the upper hooks and a "bottom" tag on the lower hook.

A captured picture is displayed on the LCD and saved to the host PC in JPEG format. The system adds annotations -one of the three types and estimated weight of the clothes, and a timestamp- to the picture as EXIF information. Figure 4 shows examples of pictures captured by TagTansu. The picture is also uploaded to the Flickr (Figure 5).
