Touch Panel Flick Gesture Image Selection Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems for printers lack an efficient method for quickly selecting desired images from multiple options, relying on cumbersome operations that hinder speedy and efficient image selection for printing on postcards or similar media.
Innovation Solution
An image display unit with a touch panel input module that detects various touch operations, including flicks and taps, to dynamically change the number of images displayed on the screen, allowing users to efficiently scroll through and select images by contracting or expanding them based on flick direction, thereby facilitating quick image selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional touch panel operations are used for image selection, then the system is simple to operate, but the image selection process is time-consuming and inefficient
Solution Approach 1:
The display dynamically adjusts the number of images shown based on detected touch operations. Single flick operations display fewer images for detailed viewing, while double flick operations display more images for quick scanning, allowing the system to adapt to different user needs in real-time
Solution Approach 2:
The system changes the parameter of image quantity displayed on screen based on the intensity of touch operations. By detecting single or double flick gestures, the system modifies the number of images from a small set to a large set, enabling users to quickly navigate through images at different granularities
2Productivity
If multiple images are displayed simultaneously, then image selection efficiency is improved, but the images become smaller and harder to view in detail
Solution Approach 1:
The display configuration is dynamic rather than static. Users can switch between viewing fewer images in detail and viewing more images simultaneously by performing different touch gestures, allowing the system to adapt to the current selection needs
Solution Approach 2:
The image selection process is segmented into different phases: initial overview phase showing multiple images, detailed examination phase showing fewer images, and rapid navigation phase using double flick operations. Each phase optimizes for its specific purpose
3Measurement precision
If users manually scroll through each image one by one, then image detail can be viewed clearly, but the selection process becomes time-consuming
Solution Approach 1:
The double flick operation enables users to skip through multiple images rapidly without stopping at each one. This allows users to quickly browse through large numbers of images to identify potential candidates, and then use single flick operations to pause and examine selected images in detail

AI summary
An image display unit is provided which includes an input module receiving touch inputs, a display module displaying an image thereon, a touched state detection module detecting a touch input made onto the input module, a touched position acquiring module acquiring a touched position of the touch input, a flick detection module detecting whether the touch input is made by a flick operation, a flick direction detection module detecting a direction of the flick operation, and a display screen changing module executing either of a first display screen changing process of increasing the number of images displayed on the display module and contracting images displayed on the display module and a second display screen changing process of decreasing the number of images displayed on the display module and expanding images displayed on the display module based on the direction of the flick operation.
