Light Segment Array Control via Color Space Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling arrays of individually addressable light segments are cumbersome, requiring significant user effort to set colors for each segment, especially when creating color gradients, and often restrict users' choices in color selection.
Innovation Solution
A system that displays a visual representation of a color space with repositionable virtual representations of light segments, allowing users to easily change and customize color gradients by manipulating these virtual representations, thereby determining user-specified light settings for the segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually pick colors for each individual light segment, then precise color control for each segment is achieved, but user effort and time consumption increase significantly
Solution Approach 1:
The system segments the light array into individually addressable light segments that can be controlled separately. Each light segment can be independently assigned a color by mapping it to a specific position in the color space, allowing precise control while reducing the cognitive load of manual configuration through automated position-based color assignment
Solution Approach 2:
The patent introduces virtual representations as intermediaries between the user and the actual light segments. These virtual representations in color space serve as a mediator that simplifies user interaction - users manipulate virtual objects rather than directly configuring each light segment's color parameters, thereby reducing user effort while maintaining precise color control
2Ease of operation
If users use paint mode with drag gestures to select colors for multiple tiles, then user effort is reduced, but color selection freedom is restricted to uniform colors across dragged areas
Solution Approach 1:
The system applies local quality by allowing different color properties at different positions within the same light segment or adjacent segments. The color space mapping enables each light segment to have its own specific color coordinates, supporting both uniform coloring (when all segments map to the same color space position) and gradient coloring (when segments map to different positions), thus providing versatility while maintaining ease of operation through simple position-based control
Solution Approach 2:
The patent transitions from traditional 2D color pickers to a 3D color space representation where light segments are mapped to positions in this space. This dimensional transformation allows users to control color gradients by manipulating positions along multiple axes (hue, saturation, brightness) simultaneously, expanding color selection freedom while keeping the interface intuitive and easy to operate
3Adaptability or versatility
If the system provides individual control for each light segment, then color selection freedom is maximized, but device complexity and interface complexity increase
Solution Approach 1:
The system merges the control of multiple light segments into a unified color space representation. Instead of providing separate controls for each segment, all segments are represented as positions in a shared color space, allowing users to control individual segments or groups of segments through a single interface paradigm, thereby reducing interface complexity while preserving individual control capability
Solution Approach 2:
The color space mapping interface serves multiple functions simultaneously: it allows individual segment color selection, gradient creation, pattern generation, and bulk color assignment. This universal interface replaces multiple specialized controls, reducing overall system complexity while maintaining adaptability for various lighting scenarios through a single multi-functional mechanism

AI summary
A system is configured to display a visual representation (41) of a color space and repositionable virtual representations (51-55) of individually addressable light segments overlaid on the visual representation of the color space. The light segments have a fixed spatial relationship in an array and the virtual representations have initial positions (71). The system is further configured to receive user input indicative of a change of one or more of the initial positions of the virtual representations and determine further positions (72) for the virtual representations based on the initial positions and the indicated change of the one or more of the initial positions. The initial and further positions are in order of the fixed spatial relationship. The system is further configured to determine light settings for the light segments based on the further positions and control the array of individually addressable light segments to render the light settings.
