Gesture-Based Parameter Setting for Image Processing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices lack an intuitive and efficient method for users to set parameters for image processing functions, requiring cumbersome button selections rather than allowing gestural inputs for parameter setting.
Innovation Solution
An image processing device with a user interface that recognizes gestures on a graphical user interface to select and set parameters for image processing functions, such as sheet tray selection and copy count, by tracing lines on the screen, allowing real-time feedback and processing based on predetermined trails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button selection methods are used for parameter setting, then device operation is reliable and easy to implement, but user interaction becomes cumbersome and parameter setting complexity increases
Solution Approach 1:
The patent replaces traditional mechanical button pressing with gesture-based input on a touch-sensitive display. Users can set parameters by drawing gestures (e.g., circles, lines) on the screen instead of navigating through multiple button presses and menus. This substitution of mechanical interaction with graphical gesture recognition simplifies parameter setting while maintaining reliability through digital signal processing and gesture pattern matching.
2Productivity
If gesture recognition is implemented for parameter setting, then user interaction becomes intuitive and efficient, but device complexity and processing requirements increase
Solution Approach 1:
The system pre-defines specific gesture patterns (e.g., circular gestures for sheet tray selection, linear gestures for copy count) that correspond to common parameter settings. By establishing these predetermined gesture templates in advance, the device can quickly match user inputs against known patterns without requiring complex real-time analysis, thus improving parameter setting efficiency while controlling processing complexity through pattern matching rather than full gesture interpretation.
Solution Approach 2:
The patent implements real-time visual feedback during gesture input, displaying the user's drawn gesture on the screen and showing preliminary interpretation results. This feedback mechanism allows users to confirm or correct their gestures before final parameter setting, improving efficiency by reducing errors and re-iterations while managing processing complexity through staged gesture validation rather than complete analysis of every gesture component.
3Manufacturing precision
If multiple parameter settings are required for image processing, then processing precision is improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent combines multiple parameter settings into a single gesture input sequence. For example, a user can draw one continuous gesture pattern to simultaneously select sheet tray, paper size, and copy count, rather than configuring each parameter separately through traditional menus. This merging of multiple parameter configuration steps into unified gesture commands maintains image processing precision by ensuring all parameters are properly set while dramatically reducing the time required for parameter setting.

AI summary
An apparatus is configured to: cause a display to display a GUI comprising a plurality of items; receive user input that is scribed over any of the plurality of items displayed on the display; provide the user with a substantially real-time feedback of the scribing by applying digital ink indicating a scribed line on the GUI; select a first item of the plurality of items based on a position of the scribing within the GUI; recognize a trail of the scribed line; in response to the trail of the scribed line being recognized as a first predetermined trail, perform, on the first item, first processing corresponding to the first predetermined trail; and in response to the trail of the scribed line being recognized as a second predetermined trail, perform second processing on the first item. The second processing corresponds to the second predetermined trail and is from the first processing.
