Touch-Based Measurement Equipment Scale Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-based measurement equipment, such as oscilloscopes, face operational inconvenience in stepwise scale adjustment due to imprecise control of two-finger pinch gestures and the small size of virtual buttons and track bars, leading to an unfriendly user interface.
Innovation Solution
A method for single-finger stepwise scale adjustment on touch-based measurement equipment, where the waveform area is divided into zones for different gestures to increment or decrement scales, providing a larger touch-sensitive range and enhancing operational convenience by allowing single-finger operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-finger pinch gesture is used for scale adjustment, then intuitive operation is improved, but measurement precision deteriorates due to imprecise control of distance between fingers
Solution Approach 1:
The patent introduces a software intermediary layer that translates imprecise two-finger pinch gestures into precise stepwise scale adjustments. The system detects the pinch gesture and automatically calculates appropriate scale factors (1×, 10×, 100×, 1000×), serving as a mediator between the user's intuitive gesture and the precise measurement control needed.
2Area of stationary object
If virtual buttons and track bars are reduced in size to ensure better waveform view, then waveform display area is improved, but ease of operation deteriorates due to difficulty in operating smaller controls
Solution Approach 1:
The patent merges the scale adjustment functionality directly into the waveform display area by enabling touch gestures on the waveform traces themselves. The waveform area serves dual purposes: displaying waveforms and enabling scale adjustment through gestures performed on or near the waveform traces, eliminating the need for separate virtual buttons and track bars.
3Area of stationary object
If scale adjustment controls are made smaller to maximize waveform area, then waveform display quality is improved, but device complexity increases due to need for multiple control elements
Solution Approach 1:
The patent makes the waveform display area universal by enabling it to serve both waveform display and scale adjustment functions. The same area that displays the waveform also responds to touch gestures for scale adjustment, eliminating the need for separate control elements and reducing overall device complexity.

AI summary
A method for scale adjustment of touch-based measurement equipment has steps of providing a touch-based screen with a waveform area; determining if a first-direction gesture or a second-direction gesture is present on the waveform area; when the first-direction gesture is present, determining if an object touches one of two portions of the waveform area divided along a second direction of the waveform area and incrementing or decrementing a first scale when positive; and when the second-direction gesture is present, determining if an object touches one of two portions of the waveform area divided along a first direction of the waveform area and incrementing or decrementing a second scale. Scale adjustment on touch-based measurement equipment using one finger can be implemented with the foregoing method.
