Abstract: An operation state detecting apparatus includes the following. An electronic device includes an operation surface and can detect whether there is contact in a plurality of positions. A sheet material can be attached to and detached from the operation surface. The sheet material includes a projecting portion which deforms to change a contact state on the operation surface according to strength of external force. A processor of the electronic device detects whether there is contact in a plurality of positions in an individual detecting region on the operation surface on which a contact state changes by the projecting portion deforming in a state with the sheet material attached to the operation surface. The processor performs a specific process according to strength or speed of an operation applied to the projecting portion judged based on a detected result of whether contact is detected in the plurality of positions.

Abstract: A track playback controlling apparatus includes at least one operation receiver, a driver, and a processor. The operation receiver receives operation to change a playback state of a track by a user. The driver causes a physical motion of the operation receiver. The processor changes a state of the motion of the operation receiver in response to a change in the playback state of the track through an operation of the operation receiver.
