Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable terminals face challenges in gesture recognition due to user motion being smaller than assumed, leading to failed recognition and increased unintended recognition, resulting in decreased user convenience and satisfaction.
Innovation Solution
An information processing device and method that acquires manipulation information and determines processing based on usage information, allowing for multiple gesture recognition conditions to adapt to user actions, enabling precise gesture recognition without impairing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gesture recognition conditions are made strict to improve recognition precision, then measurement precision is improved, but ease of operation deteriorates because users with smaller motions cannot perform manipulation
Solution Approach 1:
The patent applies dynamics by making the gesture recognition conditions changeable based on usage situations. The determination unit dynamically adjusts recognition thresholds and parameters according to the acquired usage information, allowing the system to adapt between strict conditions (for precision) and relaxed conditions (for ease of operation) depending on the context.
Solution Approach 2:
The patent changes recognition parameters such as threshold values and condition strictness based on usage situations. By adjusting these parameters dynamically, the system can maintain high recognition precision when needed while becoming more lenient to accommodate users with smaller motions in appropriate contexts.
2Ease of operation
If gesture recognition conditions are relaxed to improve ease of operation, then ease of operation is improved, but reliability deteriorates because gestures are recognized even when not intended
Solution Approach 1:
The system dynamically adjusts recognition conditions based on usage situations acquired through the acquisition unit. In situations where reliability is critical, the determination unit maintains strict conditions to prevent false recognition. In situations where ease of operation is prioritized, it relaxes conditions while still maintaining acceptable reliability through context-aware adjustments.
Solution Approach 2:
The patent changes recognition parameters such as threshold values and condition strictness based on usage situations. By adjusting these parameters dynamically, the system can maintain high recognition precision when needed while becoming more lenient to accommodate users with smaller motions in appropriate contexts.
3Device complexity
If uniform gesture recognition conditions are applied to all situations to simplify the system, then device complexity is reduced, but adaptability deteriorates because the system cannot adjust to different usage scenarios
Solution Approach 1:
The patent implements dynamic adjustment of gesture recognition conditions based on acquired usage information. The determination unit modifies recognition parameters according to the current usage situation, enabling the system to adapt to different scenarios while maintaining a relatively simple overall structure through automated context-based adjustments.
Solution Approach 2:
The system performs self-adjustment of recognition conditions based on usage information it acquires about the current situation. The determination unit automatically modifies recognition parameters without requiring manual configuration, allowing the system to adapt to different usage scenarios autonomously while keeping the user interface simple.

AI summary
An information processing device includes an acquisition unit that acquires manipulation information based on a gesture manipulation of a user and a determination unit that determines that processing is to be performed on a basis of the manipulation information. The determination unit determines that first processing is to be performed in a case where first manipulation information based on a first user manipulation is acquired, and that the first processing is to be performed, on a basis of acquired usage information of the user, in a case where second manipulation information based on a second user manipulation related to the first user manipulation is acquired.
