PURPOSE:To retrieve the information based on the environment information by storing the environment information as a retrieving key when the primary information is registered and retrieved. CONSTITUTION:The temperature, for example, is taken into consideration as the environment information. The environment temperature is fetched by an environment information sensor means 1 when the primary information is registered and retrieved. An information store control means 2 stores the primary information and the temperature information in an information store means 3 with relation secured between both information. In the second and subsequent retrieving tasks, an information retrieval control means 5 compares the temperature information inputted by a user via an environment information input means 4 with the temperature information obtained when the primary information is registered and retrieved. Thus the primary information is retrieved in the means 3, and this retrieved information is displayed via a retrieved information display means 6. In addition, the environment information including the humidity, the atmospheric pressure, the wind, the sound, the light, etc., can also be used to retrieve the information in the same way. |
