Gesture-Based Navigation for Audiovisual Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation methods for audiovisual appliances, such as TV program schedules, are inefficient and unnatural for users, relying heavily on precise pointing and object selection, limiting interaction to displays with defined objects rather than natural images.
Innovation Solution
A processing method that receives motion information from a control device, allowing users to interact with data rendered on a rendering device without the need for initial position selection, enabling natural hand motions to control data rendering, such as scrolling, zooming, and rotating, independent of pointing actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional pointing mechanisms are used for navigation, then precise object selection is achieved, but user interaction becomes unnatural and limited to displays with defined objects
Solution Approach 1:
The patent replaces the mechanical pointing system (remote control as mouse) with a gesture-based system using camera tracking. Users perform natural hand gestures in 3D space, and the system tracks these gestures to navigate and interact with the interface, eliminating the need for precise pointing while maintaining ease of operation.
Solution Approach 2:
The patent adds a spatial dimension to the interaction by tracking hand gestures in 3D space rather than 2D screen coordinates. This allows users to interact with the interface through natural hand motions in the physical space, transforming the interaction paradigm from precise pointing to gesture-based control.
2Measurement precision
If gesture tracking with high accuracy is implemented, then object selection precision is improved, but the system becomes limited to displays with defined objects and requires very high tracking accuracy
Solution Approach 1:
The patent creates a universal interaction system that works with any display type (natural images, videos, graphical interfaces) by using gesture recognition instead of object-specific pointing. The gesture-based control mechanism is adaptable to various display contents, making the system versatile across different display types.
Solution Approach 2:
Instead of requiring the display to have defined objects for pointing, the patent inverts the approach by using gesture recognition that works independently of display content. The system detects hand gestures and translates them to navigation commands, making it adaptable to any display type including natural images and videos without requiring predefined objects.
3Ease of operation
If remote control is used as a pointing device, then object selection is achieved, but the user must point with very high accuracy and the mechanism is limited to object-based displays
Solution Approach 1:
The patent replaces the mechanical pointing mechanism with an optical gesture recognition system. The camera tracks hand gestures in 3D space and translates them to navigation commands, eliminating the need for precise pointing while maintaining ease of operation. Users can interact with the interface through natural hand motions rather than precise remote control pointing.
Data Source
AI summary
A processing method for a processing device associated with a retrieval device. The processing device is driven by a control device and is able to control the retrieval of data on the retrieval device. The method includes, on the processing device, the following steps: receiving data to be retrieved on the retrieval device; obtaining a motion information item originating from the control device; and processing the data to be retrieved as a function of the motion information item received, independently of an initial position.
