Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interaction systems for controlling lighting systems are not user-friendly, as users are unsure whether requested lighting effects are obtainable, leading to disappointment when effects cannot be achieved due to limited capabilities of the lighting system, and they require extensive knowledge of lighting systems and their operation.
Innovation Solution
A user interaction system that analyzes the capabilities of multiple controllable light sources and translates them into obtainable lighting effects for specific locations, providing users with pre-emptive information on achievable effects, allowing them to select feasible options and generating control signals to achieve desired effects based on a lighting system model, with an overlay image for virtual evaluation before actual control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system provides feedback only after updating the scene image and controlling light sources, then the lighting effect can be achieved, but the user experience is poor because users cannot know a priori whether the requested effect is obtainable
Solution Approach 1:
The system performs preliminary analysis of lighting system capabilities and pre-calculates obtainable lighting effects for each location before the user provides input. This allows the system to present information about achievable effects in advance, enabling users to make informed decisions without trial-and-error attempts.
Solution Approach 2:
The system provides feedback to users about obtainable lighting effects through the display device, showing which effects can be achieved at selected locations. This feedback mechanism informs users about system capabilities before they commit to a specific effect, improving the overall user experience.
2Measurement precision
If the system requires users to have extensive knowledge of lighting systems, then precise control can be achieved, but the ease of operation deteriorates
Solution Approach 1:
The system performs self-analysis of its own capabilities by automatically evaluating which lighting effects can be achieved at each location based on the lighting system model. This eliminates the need for users to manually assess system capabilities or have specialized knowledge, while still providing precise control over achievable effects.
Solution Approach 2:
The system changes the parameter representation from technical lighting system parameters to user-friendly descriptions of obtainable effects. By translating complex lighting system capabilities into understandable effect descriptions, the system maintains control precision while improving ease of operation.
3Ease of operation
If the system provides detailed information about lighting effects for each location, then user decision-making is improved, but the device complexity increases
Solution Approach 1:
The system segments the environment into discrete locations and analyzes lighting capabilities for each location separately. This segmentation allows the system to provide targeted information about obtainable effects at each location without overwhelming the user with global system complexity, making decision-making easier while managing computational complexity through modular processing.

AI summary
The invention provides a user interaction system (100) and a method of controlling a lighting system. The user interaction system (100) comprises a display (106), a means for receiving a location indication (102), a location identification means (104) and an overlay image creator (108). The display (106) displays a subarea image and an overlay image. The subarea image is an image of a specific subarea of the environment. The location identification means (104) detects which specific location in the environment is indicated by the location indication. The overlay image creator (108) generates the overlay image. The overlay image comprises information related to a lighting effect which is obtainable by the lighting system at the specific location. The obtainable effect is an effect of at least two controllable light sources of the lighting system. The information which is related to the obtainable lighting effect is based on a lighting system model (110) which represents effects that are obtainable in the environment by controllable light sources of the lighting system.
