Video-based undo and redo operations
Abstract:
A computer-implemented method includes creating a video record of user interactions with a computer program, and displaying a control area configured to receive a rewind user command and an advance user command. In response to receiving the rewind user command, the computer program reverts to a first state that is prior to at least one of the recorded user interactions. In response to receiving the advance user command, the computer program progresses to a second state that is between the first state and a last-known state of the computer program.
