Switchable User Interface Mode for Gesture Input Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interface (UI) systems fail to efficiently switch between different input devices, leading to unintended operations when using gesture inputs, as they operate in a single UI mode without distinguishing between various input types, resulting in user input confusion and operational errors.
Innovation Solution
An apparatus and method that provide a switchable UI mode system, allowing users to transition between first and second UI modes based on different input methods, such as gesture, voice, or command inputs, using sensors like image, depth, event-based vision, proximity, or acceleration sensors, which reset recognition patterns and adjust icon sizes, positions, and arrangements to optimize user input efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single UI mode is used for all input devices, then the system structure is simple, but user input recognition becomes inaccurate and operational errors increase
Solution Approach 1:
The patent divides the unified UI mode into multiple distinct UI modes (first UI mode and second UI mode), each optimized for specific input devices. The system segments the user interface based on input device type, providing tailored recognition patterns and interaction methods for different input modalities such as gesture inputs versus traditional inputs.
2Measurement precision
If multiple recognition patterns are maintained for different input devices, then input recognition accuracy improves, but switching between modes causes operational delays
Solution Approach 1:
The system performs preliminary actions by pre-configuring recognition patterns for each UI mode and automatically detecting the input device type. When a user switches input devices, the system has already prepared the corresponding recognition patterns, enabling rapid mode switching without requiring time-consuming reconfiguration or recalibration.
3Adaptability or versatility
If gesture input is supported without dedicated UI mode, then device versatility increases, but gesture recognition precision decreases leading to unintended operations
Solution Approach 1:
The patent applies local quality by providing specialized recognition patterns and UI configurations specifically tailored for gesture inputs within the second UI mode. Instead of using a generic recognition approach for all inputs, the system optimizes the recognition sensitivity, pattern matching, and validation criteria specifically for gesture characteristics, thereby improving gesture recognition precision while maintaining overall device versatility.

AI summary
An apparatus for providing a user interface provides a first user interface mode, and can switch to a second user interface mode if it receives a user command instructing to switch the mode to the second user interface mode which has a different user command input method from the first user interface mode. In the switching process, the apparatus is configured to reset a recognition pattern to distinguish a smaller number of user input types than the number of the user input types distinguishable in the first UI mode.
