Automatic playback overshoot correction system
First Claim
1. A method, comprising:
- receiving a first command;
playing audio or video program material based on the first command;
fast forwarding through the program material based on a second command;
terminating fast forward progression through the program material based on a third command;
detecting a current position in the program material where the termination occurred;
determining a positional offset that is an estimate of user reaction time where the user recognizes an audio or video passage being played during fast forward progression and reacts to issue the third command;
calculating a new position in the program material to compensate for a difference between the current position and a predicted termination point in the program material by subtracting the positional offset from the current position; and
playing the program material starting at the new position based on the third user command;
wherein the method is performed by one or more computing devices.

Abstract
An automatic playback overshoot correction system predicts the position in the program material where the user expects to be when the user stops the fast forward progression of the program material. The system determines the position where the program material was stopped and transitions to the new mode that the user selected, starting at the stopped position with an overshoot correction factor subtracted from it. The system uses a prediction method to correctly place the user within the program upon transition out of fast forward mode and determines if the speed of the fast forward mode and then automatically subtracts a time multiple to the frame where the transition was detected and positions the user at the correct frame. The time multiple is fine tuned if the user is consistently correcting after the fast forward mode stops.
