Patent ID: 7864640

Claim:
A reproducing apparatus, comprising: a contents data recording medium in which a plurality of contents data are recorded; environmental variable acquisition means for acquiring environmental variables; reproduction history storage means for combining and storing identification information of reproduced contents data, reproduced by the reproducing apparatus, with the acquired environmental variables at a time of reproduction; and reproduction control means for calculating a similarity value between acquired environmental variables at present and acquired environmental variables stored in said reproduction history storage means for each of the plurality of contents data, and for selecting and reproducing contents data whose similarity value is judged by the reproduction control means to be closest to a predetermined threshold, wherein the reproduction control means calculates the similarity value based on the equation: S n =W c Â·âˆš{square root over (( xâˆ’x n ) 2 +( yâˆ’y n ) 2 )}{square root over (( xâˆ’x n ) 2 +( yâˆ’y n ) 2 )}+ W m Â·|mâˆ’m n |+W t Â·|tâˆ’t n |+W p Â·|pâˆ’p n | where S n is the calculated similarity value, W c is a weight factor of location, x is a present longitude, x n is nth history of longitude, y is a present latitude, y n is nth history of latitude, W m is a weight factor of time, m is a current time, m n is nth history of time, W t is a weight factor of temperature, t is a current temperature, t n is nth history of temperature, W p is a weight factor of pressure, p is a current pressure, and p n is nth history of pressure.
