Printer On-Screen Keyboard Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer and content display methods require users to perform additional actions to access an on-screen keyboard, disrupting the intended layout of web pages and reducing user convenience.
Innovation Solution
The system automatically displays an on-screen keyboard before content on a printer's display when a link with a display request parameter is activated, eliminating the need for users to manually invoke the keyboard and ensuring the layout remains intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an on-screen keyboard is automatically displayed before content, then user convenience is improved and input process is simplified, but the device complexity increases
Solution Approach 1:
The on-screen keyboard is displayed in advance before the content that requires input, so that the keyboard is already available when the user needs to input information. This preliminary action eliminates the need for users to perform additional actions to invoke the keyboard, thereby improving ease of operation while the automation handles the complexity internally
Solution Approach 2:
The system automatically detects when content requiring input is to be displayed and autonomously displays the appropriate on-screen keyboard without user intervention. The system serves itself by monitoring the display queue and activating the keyboard functionally when needed, improving user convenience without requiring complex user interactions
2Ease of operation
If an on-screen keyboard display button is added to the web page, then the keyboard can be invoked, but the layout of the displayed content is disturbed
Solution Approach 1:
The on-screen keyboard is extracted from the content display flow and displayed separately in the display area before the content appears. Instead of embedding a keyboard button within the web page layout, the keyboard is presented as a separate overlay or preliminary display element, thus maintaining the integrity of the original content layout while still providing keyboard accessibility
Solution Approach 2:
The keyboard display is moved to a different dimensional space - displayed in the display area before content rather than within the content layout itself. This temporal and spatial separation allows the keyboard to be accessible without interfering with the visual layout and design of the web page content

AI summary
Provided is technology reducing the user actions required to use an on-screen keyboard. A printer has a display; and a display controller configured to acquire a file from a server through a network, and display content based on the file on the display. When an input field to which specific information is input is included in the content, the display controller displays an on-screen keyboard configured to receive input of the specific information on the display before displaying the content.
