PROBLEM TO BE SOLVED: To provide an intention estimation device capable of easily and highly accurately estimating a selection intention from spontaneous brain waves of few sites.SOLUTION: An intention estimation device 1 sets, by a preliminary measurement, two situations (a base situation and an optimal intention) that can be created by an object person and brain waves to be measured in such situation, and defines one of them as a situation representing "Yes" and the other as a situation representing "No" (steps I and II). In the Yes/No determination, the intention estimation device makes the object person create a situation representing "Yes" or "No", compares brain waves measured at that time with the brain waves of the set two situations, and estimates the selection intension of "Yes" or "No" of the object person.COPYRIGHT: (C)2016,JPO&INPIT【課題】少ない部位の自発脳波から簡便に精度よく選択意図を推定できる意図推定装置を提供すること。【解決手段】意図推定装置1では、予備計測によって、対象者が作れる2つの状態(ベース状態と最適意図)および、これらの状態において計測される脳波を設定し、その一方を「Yes」を表す状態、もう一方を「No」を表す状態と定義する(ステップI、II)。Yes/No判定では、対象者に「Yes」か「No」を表す前記の状態を作らせ、その時に計測される脳波を、設定した2つの状態の脳波と比較して、対象者の「Yes」、「No」の選択意図を推定する(ステップIII、IV)。【選択図】図1
