3D Gesture Input System for Accessible Application Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with disabilities or limitations, such as those without the use of their fingers or who are visually impaired, face challenges interacting with software applications that require mouse clicks or visual cues, as these applications often lack alternatives for activation.
Innovation Solution
A computing device and method that utilize three-dimensional input, allowing users to provide commands through movements in a three-dimensional space, generating profiles to associate these inputs with specific actions, and providing feedback tailored to the user's capabilities, enabling interaction with software applications without the need for traditional mouse clicks or visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mouse click or finger tap interfaces are used, then application control functionality is achieved, but users with disabilities (no finger use or visual impairment) cannot operate the application
Solution Approach 1:
The patent transitions from two-dimensional screen interaction (mouse clicks, finger taps) to three-dimensional spatial interaction. Users perform gestures in 3D space above the screen, such as circular motions or tapping patterns, which are captured by sensors and mapped to application commands. This dimensional expansion provides new interaction modalities for users who cannot use traditional input methods.
Solution Approach 2:
The system introduces an intermediary layer between the user and the application: a gesture recognition system that captures 3D movements, processes them through pattern matching algorithms, and translates them into standard application commands. This intermediary enables users with disabilities to interact with applications through alternative physical gestures rather than direct screen contact.
2Adaptability or versatility
If standardized interaction methods are used for all users, then application functionality is maintained, but users with specific disabilities cannot access the application
Solution Approach 1:
The system dynamically adapts to individual user needs by allowing customization of gesture patterns for each user profile. Different users can define their own gestures or select from pre-configured options based on their specific disabilities. The system adjusts its expectations and recognition patterns in real-time based on the active user profile, providing personalized accessibility without requiring separate hardware for each user.
3Ease of operation
If three-dimensional input recognition is implemented, then users with disabilities can interact with the application, but the system complexity increases
Solution Approach 1:
The gesture recognition system is designed to handle multiple types of gestures (circular motions, tapping patterns, waving motions) and map them to various application commands (play, pause, volume control, navigation). This multi-functional approach allows a single 3D input system to replace multiple specialized input devices, reducing overall system complexity while maintaining versatility.
