Lighting Control Using User Orientation and Location Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems are not user-friendly, requiring manual input or explicit gestures, and lack seamless automatic control that follows the user's movement, leading to frustration and inefficiency in maintaining consistent ambiance.
Innovation Solution
A system that uses a controller to determine the user's orientation and location, processing this information to dynamically adjust lighting settings for lighting devices within and outside the user's field of view, ensuring a consistent ambiance without manual triggering, by transmitting control commands to the lighting devices based on determined settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control methods (remote controls, switches, applications) are used to control lighting devices, then the user has direct control over lighting settings, but the operation becomes complex and not user-friendly
Solution Approach 1:
The lighting control system automatically detects user presence, orientation, and location using sensors and processing units, then autonomously adjusts lighting settings without requiring manual user input. The system serves itself by interpreting sensor data and executing control commands based on predetermined criteria, eliminating the need for complex user interactions through remote controls or applications.
2Extent of automation
If automatic presence detection is used to control lighting, then the control becomes more automated, but the system becomes crude and cannot maintain consistent ambiance as user moves
Solution Approach 1:
The lighting control system dynamically adjusts lighting settings based on real-time user location and orientation data from sensors. As the user moves through different locations and changes orientation, the system continuously updates which lighting devices are activated and at what intensity levels, maintaining consistent ambiance adaptation throughout the environment rather than using static presence detection zones.
Solution Approach 2:
The system uses sensors to continuously monitor user presence, location, and orientation, processes this information through processing units, and feeds back control commands to lighting devices. This closed-loop feedback mechanism enables the system to automatically adapt lighting settings in response to user movement and orientation changes, maintaining ambiance consistency without manual intervention.
3Ease of operation
If gesture control is used to control lighting, then the user has more freedom of movement, but the user must consciously perform specific gestures which is not seamless
Solution Approach 1:
The system automatically detects user presence and characteristics using sensors without requiring the user to perform any deliberate gestures. The processing unit interprets sensor data to determine user location and orientation, and the control unit automatically adjusts lighting settings based on this information, providing seamless control that follows the user naturally without requiring conscious gesture performance.
