Abstract - A projector can superimpose virtual objects on or nearby target physical objects directly. This allows spatial information such as pointing a particular object or place to be presented with intended size. Also, visual characteristics of physical world can be changed by projected light. These characteristics attract researchers to apply a projector as information presentation devices for tabletop work support. One issue in projector-based information presentation is that the projected information might be hidden by the user's hand and the content might be difficult to recognize, which is known as hand occlusion problem. In this article, we propose methods based on visual and auditory feedbacks to support tabletop tasks while being occluded by his/her hands. We set an abstract task of tracing a line and compare eight types of feedbacks quantitatively and qualitatively to understand suitable feedback methods.
