Solution Overview
Problem
Existing color selection methods require cumbersome operations involving multiple key presses to adjust hue, saturation, and lightness, making it time-consuming for users to achieve desired colors.
Innovation Solution
A color selecting method that uses circular and rectilinear motion operations of a position indicator to detect angular and linear positions, allowing intuitive selection of hues, saturations, and lightness values, simplifying the color selection process by correlating motion directions with color changes.

Engineering Contradiction Analysis
1Measurement precision
If multiple keys are used for hue, saturation, and lightness selection with sequential pressing, then color selection precision is improved, but operation complexity increases and time consumption increases
Solution Approach 1:
The color selection interface is segmented into three distinct control areas: a circular region for hue selection (0-360 degrees), a first linear region for saturation selection (0-100%), and a second linear region for lightness selection (0-100%). Each area independently controls one color attribute, allowing users to adjust each parameter separately without interfering with others, thus maintaining precision while simplifying the operation process.
Solution Approach 2:
The patent transforms the traditional sequential key-pressing operation into a spatial dimension-based control system. Hue is controlled by angular position in a circular area, saturation by position in a first linear area, and lightness by position in a second linear area. This dimensional mapping allows simultaneous control of multiple color attributes through spatial positioning rather than sequential temporal operations.
2Measurement precision
If multiple keys are used for hue, saturation, and lightness selection with sequential pressing, then color selection precision is improved, but time consumption increases
Solution Approach 1:
The system displays all three control areas (circular hue area and two linear areas for saturation and lightness) simultaneously before the user begins adjustment. Each control area is pre-configured with its full range of values and visual indicators, so users can immediately begin adjusting all three color parameters in parallel without needing to switch between different modes or screens, significantly reducing the time required to achieve the desired color.
Solution Approach 2:
The patent enables continuous adjustment of hue, saturation, and lightness parameters simultaneously through the three control areas. As users move the position indicator across these areas, all three color attributes are updated in real-time without interruption or sequential delays, maintaining continuous useful action throughout the color selection process and eliminating idle time between parameter adjustments.
3Device complexity
If traditional key-based color selection is used, then device complexity is reduced, but operation efficiency decreases
Solution Approach 1:
The position indicator serves multiple functions: it can be moved to the circular control area for hue adjustment, to the first linear control area for saturation adjustment, and to the second linear control area for lightness adjustment. This single multi-functional indicator replaces the need for separate keys or controls for each color parameter, reducing the overall control interface complexity while enabling efficient simultaneous control of all three color attributes.
