Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing directional interactive display systems face challenges in accurately determining the pointing direction of multiple users simultaneously, leading to directionality disorders due to difficulties in pairing eyes and fingers or touches correctly.
Innovation Solution
A direction determination method and system that utilize image capturing devices and processing devices to detect and pair user characteristics, such as eye and touch coordinates, to accurately determine pointing directions towards a display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users interact with the display system simultaneously, then the system can support multi-user interaction, but the system cannot correctly determine which eyes and fingers correspond to the same user, leading to directionality disorders
Solution Approach 1:
The system segments the multi-user interaction problem by detecting and pairing specific characteristics (eyes and fingers) for each user separately. By dividing the complex multi-user scenario into individual user characteristic groups, the system can accurately determine pointing directions for each user without confusion, thus resolving the directionality disorder issue while maintaining multi-user interaction capability
Solution Approach 2:
The system introduces characteristic pairing as an intermediary mechanism to connect eyes and fingers to the same user. By using detected characteristics (eye coordinates, finger coordinates) as mediators, the system can correctly associate body parts with their respective users, enabling accurate pointing direction determination in multi-user scenarios
