1. A user's intention deduction apparatus, comprising: a detector configured to generate motion information based upon detected motion of a user; a first predictor configured to predict a part of the user's intention using the motion information; and a second predictor configured to predict the user's intention using the part of the user's intention predicted by the first predictor and multimodal information received from at least one multimodal sensor, wherein the first predictor predicts the part of the user's intention to be the selection of an object displayed by a screen based upon an angle and a distance between the user's two hands.
4. The user's intention deduction apparatus of claim 1 , wherein the second predictor is further configured to interpret the multimodal information received from the multimodal sensor in association with the predicted part of the user's intention to predict the user's intention.
