There is no simple solution to this challenge.
Extensive use of AUDIT could be one possible solution.

Assuming you are in 10g the amount of usage you can find in V$SEGSTAT or it's more user friendly (and also expensive) brother V$SEGMENT_STATISTICS.
But the information there isn't absolutely precise (i.e. is updated each x seconds and not always, if I remember correctly there was a note in Metalink describing that), so if you cannot find an entry for a table, it doesn't mean the table isn't touched at all.
