We have developed methods which can deal with the user's interaction without conventional conscious searching. When a user generally performs map operations with certain information retrieval intentions (less-conscious), a system using this method can detect the specific operation sequences. For example, if the user performs zooming-in and centering operations, the user is narrowing down the search area to a certain location. We define such operation sequences as chunks. The system detects the chunks and uses them to analyze the user's operations and thereby detect the user's intentions. We have developed several prototype systems based on the proposed methods.
