Handheld Touchscreen Thumbnail Cache for Remote Application Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in controlling a computer using a smart phone due to differing screen sizes and the need to monitor two screens simultaneously, leading to operational inconvenience when simulating mouse movements or keyboard inputs.
Innovation Solution
A hand-held electronic apparatus with a storage unit for caching thumbnails of application programs, a touch screen for displaying these thumbnails, and a processor to manage the layout and control commands, allowing seamless activation and control of application programs on smart TVs, desktop computers, or notebook computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simulated mouse movement or keyboard input is used to activate application programs on a computer, then the hand-held electronic apparatus can control the computer, but the operation becomes difficult due to different screen sizes and the need to watch two screens simultaneously
Solution Approach 1:
The patent displays thumbnails (visual copies) of application programs from the computer on the hand-held apparatus screen. This allows users to see and select applications without needing to watch the computer screen, solving the two-screen monitoring problem while maintaining control capability
Solution Approach 2:
The patent introduces a thumbnail display interface as an intermediary between the hand-held apparatus and the computer. This intermediary layer translates computer application information into a format suitable for the hand-held screen, eliminating the need for direct screen-to-screen coordination
2Ease of operation
If the hand-held electronic apparatus displays thumbnails of application programs, then the ease of operation is improved, but the device complexity increases due to additional storage and processing requirements
Solution Approach 1:
The patent pre-generates and stores thumbnails of application programs in the hand-held apparatus before the user needs to select them. This preliminary preparation eliminates the need for real-time image processing during operation, reducing the actual processing burden during use
Solution Approach 2:
The patent extracts only the essential visual information (thumbnails) from the full application program interfaces and stores only these extracted elements. This selective extraction reduces storage requirements and processing needs compared to handling complete application interfaces

AI summary
A hand-held electronic apparatus having a function of activating an application program of an electronic apparatus is provided, including: a storage apparatus, configured to store an operating system and a thumbnail cache file received from the electronic apparatus, where the thumbnail cache file includes a thumb corresponding to an application program in the electronic apparatus; a touch screen, configured to display the thumbnail; and a processor, configured to display the thumbnail on the touch screen by using a thumbnail layout manner specified by the operating system. The present invention further provides a method for activating an application program of an electronic apparatus, and a computer program product, where an application program installed in an electronic apparatus is activated by a hand-held electronic apparatus, so as to avoid difficulty in an operation of simulated mouse movement or keyboard input by using a hand-held electronic apparatus.
