System and Method for Intelligent Undo /Redo Operations Based on Eye Tracking
When working on large documents, blocks of code, or other files, it is common to make mistakes that compromise the quality of the file. In many cases, these mistakes are large and may have been made earlier in a session with the file. The undo/redo functions are designed to automatically handle such mistakes; however, there are weaknesses in the current embodiments of these functions.
The concept of nonlinear undo/redo allows a user to select from a list any changes to undo/redo. Nonlinear functions such as undo/redo can be enhanced.
The novel and non-obvious system and method enhance nonlinear undo/redo operations by incorporating eye tracking as a determinant of content for an undo/redo action. This is based upon the tendency for the problem or issue to be located in the last place at which the user looked within a file.
To implement the system and method in a preferred embodiment:
1. Track changes that occur (existing art covers this behavior)
A. Add metadata that indicates visual coordinates of content changes
B. Store location and change metadata in the change history list
2. Track user eyes (existing art covers this behavior)
3. When undo or redo is pressed, check gaze
A. At the time the gaze is being tracked
B. Within a very recent time frame prior to or after checking gaze
i. before or after checking may be user configurable depending on habits
ii.time threshold may be user con...
