Position-Aware Gesture Control for Lighting Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gesture control systems for lighting do not adapt lighting responses based on the user's position within a space, resulting in inconsistent lighting control functions regardless of location.
Innovation Solution
A controller system that integrates motion detection logic, positioning logic, and control policy selection logic to interpret gestures differently based on the user's position, allowing for varying lighting responses depending on location and orientation within a space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gesture control is implemented without position-based adaptation, then the system is simple and easy to operate, but the lighting response is inconsistent and not context-aware
Solution Approach 1:
The space is segmented into multiple zones, and the system selects different control policies based on which zone the user is in. This allows the same gesture to have different meanings depending on location, providing context-aware control without requiring a completely new system architecture.
Solution Approach 2:
The control policy is made dynamic by selecting it based on the user's detected position. The system transitions from a static one-to-one gesture-response mapping to a dynamic many-to-many mapping where the response depends on the current zone, enabling adaptability while maintaining operational simplicity.
2Adaptability or versatility
If multiple control policies are implemented for different positions, then lighting control becomes context-aware, but the device complexity increases
Solution Approach 1:
Multiple control policies are pre-configured and stored in the system, each associated with specific zones. When a user performs a gesture, the system quickly retrieves the appropriate pre-defined policy based on the detected zone, avoiding the need for complex real-time decision-making algorithms.
Solution Approach 2:
A control policy selection module acts as an intermediary between the gesture detection module and the lighting control module. This intermediary selects the appropriate policy based on position information, simplifying the overall control logic by decoupling gesture recognition from lighting response selection.

AI summary
A controller, method and program for controlling one or more sources of a utility to provide the utility into a space occupied by one or more users, e.g. for controlling light sources illuminating an indoor or outdoor space. An input from one or more sensors is processed to detect motions of a user in the space, to detect that the motions correspond to predetermined gestures performed by the user, and to detect a position from which each gesture was performed. Further, each of a plurality of discrete control policies is associated with a respective combination of predetermined gesture and positional demarcation within the space. Each control policy defines a respective response of the utility to the respective associated gesture. For gestures performed from each of a plurality of different positions, a different control policy is selected based on being associated with the detected gesture and detected position.
