Lighting Device Selection via Relative Directional Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems require precise mapping of user position and orientation to select lighting devices, leading to user frustration when this mapping is off, making the selection process incomprehensible and negatively impacting user experience.
Innovation Solution
A method that allows users to select a lighting device based on a first direction input, with feedback notification, and correct the selection using a second user input relative to the first device, such as a directional gesture or voice command, enabling intuitive selection even with incorrect positional mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise mapping of user position and orientation is used to select lighting devices, then selection accuracy is improved, but system complexity increases and user experience deteriorates when mapping is off
Solution Approach 1:
The system provides visual feedback by highlighting the selected lighting device on the user interface, allowing users to verify if the correct device is selected. This feedback mechanism enables users to detect selection errors and trigger corrective actions, resolving the contradiction by making the system's internal state observable without increasing complexity
Solution Approach 2:
Instead of requiring users to precisely aim at the target device (which fails when mapping is off), the system inverts the approach by allowing users to select a device and then provide relative directional corrections. This inversion transforms an absolute positioning problem into a relative adjustment problem, reducing the precision requirements while maintaining selection accuracy
2Measurement precision
If precise mapping of user position and orientation is used to select lighting devices, then selection accuracy is improved, but ease of operation deteriorates when mapping is off
Solution Approach 1:
The system inverts the selection paradigm from absolute pointing to relative correction. Users first select a lighting device (any device), then provide relative directional input to adjust the selection. This inversion makes the system robust to mapping errors and maintains ease of operation regardless of mapping accuracy
Solution Approach 2:
The system provides immediate visual feedback showing which device is currently selected and what directional correction is needed. This feedback loop guides users through the correction process, making it intuitive and easy to operate even when the initial selection is incorrect due to mapping errors
3Adaptability or versatility
If relative direction mapping onto first lighting device is used, then adaptability improves, but measurement precision requirements change
Solution Approach 1:
The system inverts the reference frame for directional input. Instead of mapping directions relative to the user's absolute position, directions are mapped relative to the selected lighting device's position. This inversion allows flexible adaptability since users can correct selections without needing precise absolute positioning, while the system handles the coordinate transformation
Solution Approach 2:
The system changes the reference parameter for directional mapping from user-centric coordinates to device-centric coordinates. This parameter change enables the same directional input to work correctly regardless of the user's absolute position or mapping accuracy, providing adaptability while reducing precision requirements
