Graphic Meter Display Seamless Pointer Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Graphic meter displays experience a sense of incompatibility due to the simultaneous visibility of motion blur and normal displays during switching, causing after-images and an unnatural viewing experience when the pointer moves rapidly or stops.
Innovation Solution
A graphic meter display that switches between motion blur and normal pointer images based on speed, using an intermediate pointer image generated from the motion blur and normal images, ensuring seamless transitions by calculating and displaying a rectangular intermediate image when switching occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion blur display is used for rapidly moving pointer, then after-images are canceled and visibility is improved, but when switching to normal display, a gap appears causing sense of incompatibility
Solution Approach 1:
An intermediate pointer image is introduced as a mediator between the motion blur pointer image and the normal pointer image. This intermediate image contains partial after-image information that bridges the visual gap during transition, eliminating the sense of incompatibility while maintaining the benefits of both display modes.
Solution Approach 2:
The display system dynamically adjusts the pointer image based on moving speed, transitioning from motion blur display at high speeds to normal display at low speeds, with an intermediate state during transition. This dynamic adaptation optimizes visibility across different operating conditions.
2Measurement precision
If motion blur display is used to cancel after-images, then rapidly moving pointer becomes visible, but switching between motion blur and normal display creates visual gap
Solution Approach 1:
The intermediate pointer image serves as a visual mediator that maintains continuity during mode switching. It preserves partial after-image characteristics while transitioning to the normal pointer image, ensuring smooth visual perception without abrupt gaps or incompatibility sensations.
Solution Approach 2:
The system changes the after-image parameter gradually during transition. The intermediate pointer image contains a reduced but non-zero after-image effect, creating a smooth parameter transition from the strong after-image of motion blur display to the no after-image state of normal display.

AI summary
When switching a motion blur pointer image to a normal pointer image, an intermediate pointer image is displayed between the motion blur pointer image and the normal pointer image. The intermediate pointer image is a rectangle, and coordinates of vertexes of the rectangle are composed of coordinates of vertexes of the motion blur pointer image and the next normal pointer image.
