Motion Sensor Cursor for Precise Lighting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling lighting parameters like color, color temperature, and dimming using mobile devices are limited by the imprecision of touch screen interfaces, particularly due to the small scale of touch screen surfaces and the large contact area of human fingertips, which makes fine adjustments difficult.
Innovation Solution
A method utilizing a mobile device with a motion sensor to control a cursor on a graphic user interface, allowing users to select lighting settings through angular rotations and movements, enabling finer precision and simultaneous projection of selected light settings by luminaires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch screen interface is used for controlling lighting parameters, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent introduces a cursor as an intermediary element between the user's touch input and the lighting control parameters. The cursor acts as a mediator that can be positioned precisely on the display screen, allowing users to select lighting parameters with higher accuracy than direct finger contact would permit. The cursor's position is controlled by touch input but provides more precise selection capability.
Solution Approach 2:
The patent creates a visual representation (cursor) that copies or represents the user's selection intent on the display screen. This cursor copy allows the user to see exactly which parameter is being selected, providing visual confirmation and enabling more precise control than direct finger contact alone would allow.
2Area of moving object
If touch screen surface is small, then device portability is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent adds the dimension of visual display to the control interface. Instead of relying solely on the physical size of the touch screen, it utilizes the display screen's visual space to show a cursor and parameter options. This allows precise parameter selection through visual positioning on the display rather than being constrained by the physical touch surface area.
3Ease of operation
If fingertip contact area is large, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The cursor serves as an intermediary that decouples the user's finger contact area from the precision of parameter selection. The user can touch anywhere on the screen to move the cursor to a precise location, and the cursor's small visual size on display provides the precision that the large fingertip cannot achieve directly.

AI summary
A method and system of controlling lighting that includes displaying on a graphic user interface of a mobile device a grid of light functions. The grid of light functions including a plurality of selectable light function settings. The method may further include selecting a light function setting from the selectable light function settings by traversing a cursor over the light function setting that is selected, wherein motion of the cursor is controlled by motion of the mobile device that includes a motion sensor for correlating said motion of the mobile device to said traversing of the cursor. The method may also include transmitting a control signal for the light function setting that is selected from said mobile device to a luminaire, wherein the luminaire projects light with properties consistent with said light function setting simultaneously with the cursor being present on said light function that is selected.
