<p>A measurement unit (110) measures electromagnetic properties of a user's brain. An image generating unit (120) analyzes the electromagnetic properties which the measurement unit (110) has measured, and, on the basis of the result of the analysis, generates a perception image. An object specification unit (130) extracts a characteristic quantity of the perception image which the image generation unit (120) has generated, and specifies, on the basis of the extracted characteristic quantity, an object which the perception image denotes. A search range determination unit (140) determines a search range, on the basis of the object which the object specification unit (130) has specified. A search unit (150), using a perception image, carries out a search of information relating to this perception image, in the search range which the search range determination unit (150) has determined.</p> |
