Touch Gesture Control for Signal Analyzers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held test instruments, such as signal/spectrum analyzers and oscilloscopes, face challenges in intuitive control due to complex button mechanisms and non-intuitive graphical user interfaces, especially under adverse lighting conditions, requiring significant user experience to operate correctly.
Innovation Solution
The implementation of a touch-enabled display screen that recognizes multi-touch control gestures, allowing users to control the instrument with unambiguous gestures that correspond to specific commands, eliminating the need to identify and press specific buttons, and enabling intuitive operation even in harsh conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are provided for controlling data display and operations, then the instrument can perform various functions, but the device complexity increases and ease of operation deteriorates under adverse lighting conditions
Solution Approach 1:
The patent replaces mechanical button presses with touch gestures on a display screen. The touch-enabled display screen detects finger movements and translates them into control commands, eliminating the need for physical buttons while maintaining comprehensive control functionality.
Solution Approach 2:
The display screen serves multiple functions: it displays measurement data and simultaneously acts as the control interface for all instrument operations. This multi-functionality reduces the number of separate components needed while improving ease of operation.
2Device complexity
If a graphical user interface with icons is used for control, then the interface can be more visual, but the intuitiveness deteriorates depending on icon design requiring user experience
Solution Approach 1:
The patent changes the control parameters from static icon selection to dynamic gesture-based control. Different gesture types (tap, swipe, pinch, rotate) and their variations (direction, duration, intensity) provide intuitive control without requiring users to learn specific icon meanings.
Solution Approach 2:
The control interface transitions from static icons to dynamic gestures that mimic natural hand movements. The system detects and interprets various gesture dynamics including movement direction, speed, and pattern to execute corresponding commands, making the interface more intuitive.
3Loss of information
If the display screen shows all available data, then information completeness is improved, but the readability of individual data elements deteriorates due to screen space limitations
Solution Approach 1:
The patent uses multi-touch gestures that operate in spatial dimensions on the touchscreen surface. Users can pinch to zoom, swipe to navigate, and rotate to change perspectives, effectively adding dimensional control to access and view data elements at different scales and positions without losing information.
Solution Approach 2:
The display dynamically adjusts its content presentation based on detected gestures. Pinch gestures zoom in/out to change the scale of displayed data, swipe gestures transition between different data views, and the system continuously adapts the display state to maintain readability while preserving access to all data.
Data Source
AI summary
An instrument is described which comprises an input for receiving a signal, a data processing unit for analyzing said received signal and providing data to be displayed, and a touch enabled display screen for displaying said data to be displayed and receiving commands directed to said data processing unit. Said commands comprise commands that determine how said data is displayed on the touch enabled display screen and commands that determine operations that are performed by said instrument and/or said data processing unit. Said commands are specified by control gestures on said touch enabled display screen. Said control gestures are unambiguously related to certain commands. Said data processing unit recognizes said control gestures wherein said data processing unit is configured to determine a corresponding command specified by said detected control gesture and to process said determined command. Said instrument is a test instrument for measuring and/or analyzing said received signal.
