Diamond Shaped Color Selection Interface For Smart Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current color selection schemes for smart home lighting, typically using circular designs, lack precision and fine adjustment capabilities due to their geometry, making it difficult for users to accurately select specific colors and dimming levels using touch screen interfaces, especially on mobile devices with small screens and limited sensitivity.
Innovation Solution
A diamond-shaped perimeter grid of selectable light color settings surrounding a dimming setting is used on a graphic user interface, allowing users to navigate and select colors through linear motions, providing precise control over hue, saturation, and dimming levels by utilizing a touch interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a circular color selection grid is used, then the interface is simple and familiar, but precision and fine adjustment capabilities are insufficient
Solution Approach 1:
The circular color grid is segmented into a diamond-shaped perimeter grid with distinct color regions (red, green, blue, yellow quadrants). This segmentation allows users to navigate to specific color regions and make precise selections by moving along linear edges rather than attempting to hit a specific point in a continuous circle, thereby improving color selection precision while maintaining interface simplicity.
Solution Approach 2:
A cursor is introduced as an intermediary element that moves in response to device motions (accelerometer, gyroscope, magnetometer). The cursor acts as a mediator between the user's physical device movements and the color selection on the interface, enabling precise color selection through linear motion along the diamond grid edges while keeping the operation intuitive and simple.
2Manufacturing precision
If a circular grid design is used, then the layout is compact, but fine adjustment capabilities are limited
Solution Approach 1:
The traditional symmetric circular grid is replaced with an asymmetric diamond-shaped perimeter grid. This asymmetric design provides linear edges that facilitate precise cursor movement and color selection through directional gestures, improving color selection accuracy while the overall diamond shape remains geometrically simple and computationally efficient to implement.
3Measurement precision
If touch screen sensitivity is limited, then the device is portable and user-friendly, but precision in color selection is difficult to achieve
Solution Approach 1:
The cursor serves as an intermediary that amplifies the effect of device motions. Instead of requiring high touch screen sensitivity to detect precise finger movements, the system uses the cursor to translate device motions (accelerometer, gyroscope, magnetometer) into precise color selections. This intermediary mechanism enables high precision color selection on portable devices with limited touch sensitivity.
Solution Approach 2:
The color selection mechanism transitions from direct 2D touch screen interaction to 3D device motion detection. By utilizing the third dimension (device orientation and motion in space), the system achieves precise color selection without relying on high touch screen sensitivity, making it suitable for portable devices.

AI summary
A method for selecting colors to be projected from a lamp is provided. In one embodiment, the method includes pairing a lamp with a graphic user interface having a diamond shaped perimeter grid of selectable light color settings surrounding a selectable dimming setting. The diamond shaped perimeter grid including four color based segments, wherein each of the four color based segments provides a different family of colors. The user of the graphic user interface selects the selectable light color setting from the graphic user interface, wherein a device including the graphic user interface transmits a signal to the lamp to emit light having a color that is consistent with the selectable light color setting that has been selected by the user.
