Browser-Based Equipment Control via Conversion Script Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing Web pages to operate multifunction peripherals like scanners and printers through browser programs is challenging due to the need for detailed knowledge about the equipment's state changes, making it difficult to create appropriate user interfaces.
Innovation Solution
An information processing device that includes an operation display unit, a communication unit, a conversion script processing unit, and a display control unit, which acquires and analyzes equipment states to provide a user interface without requiring detailed knowledge of the equipment, by executing a browser program and using a conversion script to issue events and update the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed information about equipment state changes is provided through event notifying, then the equipment can be controlled precisely, but the difficulty of developing Web pages increases due to required detailed knowledge
Solution Approach 1:
The patent introduces an intermediary component that translates detailed equipment state changes into simplified user interface events. This mediator layer processes the raw equipment data and presents it in a standardized, easier-to-understand format for Web page developers, reducing the complexity of development while maintaining precise equipment monitoring capabilities.
2Speed
If comprehensive equipment state information is transmitted to the browser program, then the user interface can be highly responsive, but the amount of data processing and communication overhead increases
Solution Approach 1:
The patent extracts only the essential and relevant equipment state information needed for user interface updates, rather than transmitting all detailed data. This selective extraction reduces communication overhead and processing requirements while maintaining the responsiveness of the user interface by focusing on critical state changes.

AI summary
An information processing device includes: an operation display unit that displays information for a user and receives an input from the user; and an information processing unit including a processor that executes a browser program. The information processing unit includes: a communication unit that functions by the processor executing the browser program, and acquires an operation program and a conversion script that provide a user interface for operating an equipment through the operation display unit; a conversion script processing unit that functions by the processor executing the conversion script on the browser program, analyzes a state of the equipment, and issues an event corresponding to the state of the equipment; and a display control unit that functions by the processor executing the operation program on the browser program, and provides the user interface corresponding to the event through the operation display unit in response to issuance of the event.
