Multi-touch Gesture Dictionary Visual Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multi-touch interfaces face challenges in learning and remembering the meanings of numerous gestures due to the lack of efficient methods for indexing and accessing gesture information, as verbal descriptions are cumbersome and context-dependent.
Innovation Solution
A gesture dictionary application that provides visual and textual depictions of multi-touch gestures, allowing users to interactively learn and assign meanings to gestures, with features like motion icons, animations, and feedback, facilitating the learning and retention of gesture languages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If verbal descriptions are used to index and access gesture information, then gesture meanings can be communicated, but the method becomes cumbersome and context-dependent
Solution Approach 1:
The patent introduces visual icons as an intermediary between the user and gesture information. Instead of using verbal descriptions directly, the system employs graphical icons that visually represent gestures and their meanings, making the system easier to use without requiring complex verbal indexing or context-dependent interpretation
Solution Approach 2:
The patent creates visual copies or representations of actual gestures through icons and animations. These visual copies capture the essential characteristics of gestures without requiring the full complexity of verbal description, allowing users to quickly understand gesture meanings through visual analogies rather than text
2Adaptability or versatility
If the number of multi-touch gestures is increased to convey complex meanings, then gesture language capability is improved, but the difficulty of learning and remembering gestures increases
Solution Approach 1:
The patent segments the complex gesture language into manageable components by providing individual dictionary entries for each gesture. Each entry is presented separately with its own visual icon and description, allowing users to learn gestures incrementally rather than attempting to memorize the entire gesture set at once
Solution Approach 2:
The patent prepares gesture information in advance through a pre-organized gesture dictionary with visual icons and descriptions. This preliminary organization allows users to quickly lookup and learn specific gestures when needed, rather than requiring them to memorize all gestures beforehand, thus facilitating easier learning while maintaining comprehensive gesture capability
