Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording systems lack the ability for users to manually control special effects, such as changing the frame rate in real time during recording, leading to inaccuracies and unintended activation of operations due to finger drift on touch screens.
Innovation Solution
A real-time video special effects system with a graphical user interface that allows users to control the speed rate of video data through affordances and guidelines, enabling manual adjustment of frame rates during recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch screen controls are used for frame rate adjustment, then ease of operation is improved, but manufacturing precision deteriorates due to finger drift causing accidental activation
Solution Approach 1:
The patent applies local quality by creating guidelines with different visual characteristics (brightness, thickness, color) at different positions. The selected guideline has enhanced visual properties to indicate the current active frame rate, while unselected guidelines have standard properties. This localized differentiation allows precise control by clearly indicating which threshold will be activated, reducing finger drift errors while maintaining touch interface ease of use.
Solution Approach 2:
The patent implements feedback by displaying visual guidelines that provide real-time information about frame rate thresholds. When the user drags the slider, the system provides visual feedback through guideline highlighting and position updates, allowing the user to see exactly which frame rate will be activated before confirmation. This feedback mechanism prevents accidental activation by ensuring the user is aware of the intended operation.
2Adaptability or versatility
If real-time frame rate control is added, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a control interface that handles multiple frame rate values (1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 30x, 60x, 120x, 240x) within a single unified slider mechanism. The same interface structure and interaction pattern work for all frame rate adjustments, eliminating the need for separate controls for each frame rate level. This multi-functional design achieves high adaptability while maintaining relatively simple device architecture.
3Measurement precision
If visual guidelines are displayed for each frame rate, then measurement precision is improved, but loss of information increases due to interface clutter
Solution Approach 1:
The patent applies local quality by making only the currently selected or relevant guideline visually prominent, while keeping other guidelines subdued or hidden. This selective highlighting provides precise measurement information about the active frame rate threshold without overwhelming the user with all possible frame rate options simultaneously. The interface displays information contextually based on the user's current interaction state.
Solution Approach 2:
The patent applies partial action by displaying only the necessary subset of frame rate guidelines at any given moment rather than all possible guidelines continuously. The system reveals frame rate information progressively as the user interacts with the slider, showing only the relevant thresholds needed for the current adjustment context. This reduces interface clutter while maintaining measurement precision for the active control range.
Data Source
AI summary
A user interface system and method of recording/editing a video while applying special effects in real time. The interface can be associated with an electronic device including a processor in communication with a camera and a memory unit, or can receive previously prepared video. A first speed rate of the video can be changed by modifying a frame in the video data to create a different modified video data at a modified speed rate that. This allows for continuous recording and/or displaying of video at different speed rates without altering operations or settings. The interface can include time guidelines associated with selectable speed rates, to display which speed rate setting is near a touching finger or pointing device. The guidelines can be activated automatically or can change color, shape, intensity or other property based on finger location, and can aid in object positioning in a field-of-view.
