INFORMATION REPRODUCING APPARATUS AND METHOD, AND COMPUTER PROGRAM

摘要

An information reproducing apparatus (1) comprises a reading means (10) for reading content data, an operation means (41) constructed so as to be rotatable by a user operation, a detection means (42) for detecting the content of the rotational operation of the operation means as an operation signal (d), a generation means (22) for generating a modulation signal (d'') by adding a predetermined additional signal (d') oscillating at a variable frequency or a fixed frequency to the operation signal, and a reproduction means (15) for reproducing the content data while specifying the reproduction speed and the reproduction direction of the content data according to the modulation signal.
