Eye-Tracked Lighting Commissioning Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency of the lighting control system commissioning process is exacerbated by frequent switching between the commissioning program and lighting components, leading to reduced efficiency and unnecessary audio feedback.
Innovation Solution
A method and system that automatically switch the lighting control system commissioning program to graphical or audio/haptic modes based on the user's orientation, using face or eye detection to determine focus, ensuring feedback is given sparingly and only when necessary, and input is accepted through appropriate means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the commissioning engineer frequently switches focus between the commissioning program and lighting components, then the commissioning process can be completed, but the efficiency of the commissioning process is reduced
Solution Approach 1:
The patent replaces manual focus switching with automatic focus detection using eye tracking technology. The system detects eye gaze direction to automatically determine when the user is looking at the display versus the physical lighting components, and switches control modes accordingly without requiring manual intervention.
Solution Approach 2:
The system performs self-service by automatically detecting user focus state through eye tracking and autonomously switching between control modes. The commissioning software monitors eye gaze and independently determines when to switch between graphical interface mode and audio feedback mode, eliminating the need for manual mode switching.
2Reliability
If audio feedback is provided continuously during commissioning, then the user is kept informed, but unnecessary audio feedback becomes annoying
Solution Approach 1:
The patent applies dynamics by making the feedback mode adaptable based on real-time detection of user focus state. The system dynamically switches between graphical feedback mode (when user is looking at display) and audio feedback mode (when user is looking at lighting components), ensuring feedback is provided only when physically necessary and in the appropriate modality.
Solution Approach 2:
The system changes the feedback parameter (modalities of feedback) based on detected focus state. When eye tracking detects the user is looking at the display, the system uses graphical feedback parameters; when the user looks at lighting components, it switches to audio feedback parameters. This dynamic parameter adjustment eliminates unnecessary audio feedback while maintaining reliable communication.
