Semi-Transparent Waveform Interface for Mobile ECG Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with constrained display areas and low input resolution make it difficult to compare and analyze electrocardiogram waveforms, particularly when trying to align or compare sections of waveforms, due to cluttered interfaces and limited screen space.
Innovation Solution
A method and apparatus that utilize a semi-transparent interface control to display a selected portion of a waveform, allowing it to be superimposed over another waveform or section of the same waveform, enabling easy alignment and comparison through touch screen input features like scrolling calipers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a semi-transparent interface control is used to display a selected portion of a waveform, then the ability to compare waveforms is improved, but the display complexity increases
Solution Approach 1:
The patent applies transparency effects to the interface control, allowing the selected portion of the first waveform to be displayed in a semi-transparent manner over the second waveform. This visual technique enables practitioners to see both waveforms simultaneously, improving comparison accuracy without requiring separate display areas or additional hardware.
2Adaptability or versatility
If the display area is used to show multiple waveforms simultaneously, then the comparison capability is improved, but the available input resolution decreases
Solution Approach 1:
The patent divides the display into functional zones: the main display area shows the second waveform for context, while the semi-transparent interface control overlays the selected portion of the first waveform. This segmentation allows practitioners to focus on specific comparison regions while maintaining access to the full waveform context, enabling effective comparison on mobile devices with limited screen real estate.
3Area of stationary object
If the display interface is condensed to show both waveforms, then the space utilization is improved, but the analysis difficulty increases
Solution Approach 1:
The semi-transparent interface control acts as an intermediary layer between the two waveforms, allowing both to be visible simultaneously without obscuring each other. This mediator enables practitioners to easily detect and measure differences between waveforms by providing visual access to both datasets in the same spatial context, reducing analysis difficulty despite condensed display space.

AI summary
A method, apparatus and computer program product are therefore provided in order to provide for display of waveforms. An example method may include displaying a first waveform, receiving an input selecting a portion of the first waveform, and generating, using a processor, an interface control displaying the selected portion of the first waveform. The interface control may include a semi-transparent display area and the selected portion of the first waveform may be displayed on the semi-transparent display area. The method may also include displaying the interface control concurrently with a second waveform such that at least a portion of the second waveform is visible through the semi-transparent display area of the interface control.
