Media Project Undo Preview Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media-based project creation software makes it difficult for users to intuitively see what operations will be undone or reversed when performing an undo action, leading to repetitive undo and redo processes, which is time-consuming and frustrating.
Innovation Solution
A method and system that allow users to easily reverse edit operations in a media-rich project by displaying a pre-edited view, saving it as a last-edited view, and using a reverse function to revert back to the pre-edited view through a client-server environment, with features like automatic grouping of photos based on image heuristics and indicators for user actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional undo operations are used in media-based project creation software, then users can reverse editing actions, but users cannot intuitively see what operation will be undone, leading to repetitive undo and redo cycles
Solution Approach 1:
The patent implements a visual feedback mechanism that displays a preview of the state before the undo operation. When a user triggers an undo action, the system shows them exactly what the project will look like after the reversal, allowing informed decision-making without requiring trial-and-error undo/redo cycles. This feedback loop resolves the contradiction by providing both information about the operation and maintaining ease of operation.
Solution Approach 2:
The system performs a preliminary action by calculating and displaying the pre-undo state before the user actually commits to the undo operation. This allows users to see the consequence of the undo action in advance, preventing information loss about what will be reversed while avoiding the need for repetitive operations.
2Loss of information
If users manually undo and redo operations to see what is being reversed, then they can understand the undo effect, but they waste time and become frustrated
Solution Approach 1:
The patent creates a visual copy or preview of the project state before the undo operation. Instead of requiring users to perform actual undo/redo cycles, the system generates a visual representation (copy) of what the project will look like after undoing, allowing users to understand the effect instantly without time loss.
Solution Approach 2:
The system provides immediate visual feedback showing the pre-undo state, eliminating the need for users to manually test undo operations to understand their effect. This feedback mechanism simultaneously provides understanding of the undo effect and prevents time waste by displaying the information upfront.
3Adaptability or versatility
If the software tracks multiple views and editing locations, then it can handle complex media projects, but it becomes difficult to track and reverse specific operations
Solution Approach 1:
The patent segments the complex project state into manageable components by tracking specific editing operations and their associated pre-states separately. Each editing action is recorded with its own pre-undo representation, allowing the system to handle complex multi-view projects while maintaining organized, trackable operation history that simplifies the reversal process.

AI summary
Methods and systems of reversing edit operations of a media-rich project are disclosed. In one embodiment, the method comprises, offering to a user an editing action on a pre-edited view of a media-rich project, in which the editing action after being performed on the pre-edited view displays a first-edited view of the project; saving, in response to the user switching to a second view, the first-edited view as a last-edited view; and reversing, in response to a user reverse action, the editing action of the last-edited view by initiating a reverse function, in which the reverse function comprises two steps, in which a first step causes the editor to exit from the second view and to land on the last-edited view, and a second step causes the last-edited view to revert to the pre-edited view.
