Mobile Video Annotation Resizing and Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face challenges in displaying and interacting with video annotations due to their smaller screen size and resolution, leading to issues with visual intersections and limited user interface command options, which can result in a suboptimal user experience.
Innovation Solution
The method involves modifying video annotations by resizing and repositioning them to fit the mobile device's screen, and defining user interface commands through touch screens, cameras, microphones, and accelerometers to perform actions related to the video stream, such as playback control and content selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video annotations are displayed on mobile computing devices with smaller screens, then portability and accessibility are improved, but visual intersections and readability deteriorate
Solution Approach 1:
The system dynamically adjusts annotation properties (size, position, opacity) based on detected visual intersections and screen characteristics. Annotations are not static but adapt in real-time to maintain readability while preserving portability benefits.
Solution Approach 2:
The patent changes multiple parameters of video annotations including size, position, transparency, and styling based on detected intersections and device characteristics. This allows the same annotation content to be displayed effectively across different screen sizes and conditions.
2Device complexity
If traditional user interface commands are used on mobile devices, then simplicity is maintained, but interaction options and user experience deteriorate
Solution Approach 1:
The system implements multiple types of user interface commands (touch gestures, voice commands, camera-based interactions, accelerometer-based gestures) that can all trigger the same annotation actions. This multi-functionality approach expands interaction options while maintaining ease of use through familiar input methods.
Solution Approach 2:
The system automatically detects user intent through various sensors and input methods, reducing the need for complex menu navigation. The interface adapts to user behavior patterns, providing relevant controls contextually without requiring users to search through multiple layers of complexity.
3Manufacturing precision
If video annotations are made larger to improve readability, then visual intersections and screen space utilization deteriorate
Solution Approach 1:
Different annotations receive different sizing and styling treatments based on their specific context, importance, and detected intersections. Rather than uniformly enlarging all annotations, the system applies local adjustments to individual elements, optimizing readability where needed while preserving screen space elsewhere.
Solution Approach 2:
The system uses the dimension of transparency/opacity to resolve conflicts between readability and screen space. Annotations can be made semi-transparent or fade in/out based on user interaction state, allowing multiple layers of information to coexist without requiring additional screen real estate.

AI summary
Systems and methods for displaying annotated video content by mobile computing devices. An example method may comprise: presenting, on a display of a mobile computing device, a video stream including a plurality of video frames; presenting a video annotation overlaid over a frame of the plurality of video frames; receiving a user interface command via a user input interface of the mobile computing device; and performing an action related to the video annotation, the action defined by the user interface command.
