Linking User Terminal with Receiving Terminal for Touch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The small size of electronic terminals, such as smartphones, limits the enjoyment of games and web surfing due to the small screen size, making it inconvenient to check emails and other content.
Innovation Solution
A method and system that links a smaller user terminal with a larger receiving terminal, allowing the user to control the smaller terminal while viewing the larger terminal, by transmitting position information of a touch means and changing touch modes based on user input, enabling better control and reduced errors through visual feedback on the larger screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the electronic terminal size is reduced for portability, then the terminal becomes more portable and convenient to carry, but the screen size becomes too small to fully enjoy games, web surfing, and email reading
Solution Approach 1:
The patent combines the small user terminal with a large receiving terminal (TV) to create a hybrid system. The user terminal maintains its portability while the TV provides the large screen area needed for enjoying content. The two terminals are merged through wireless communication links, allowing the user to control the small terminal while viewing on the large TV screen.
2Area of stationary object
If the screen size is increased to improve content enjoyment, then the terminal becomes less portable and more difficult to carry
Solution Approach 1:
The system is segmented into two separate terminals: a small portable user terminal that maintains ease of carrying, and a large receiving terminal (TV) that provides the large screen area. Each terminal performs its specialized function - the user terminal for control and portability, the TV for large-screen display - resolving the contradiction between screen size and portability.
3Measurement precision
If touch pressure or touch area information is transmitted to the receiving terminal, then the control precision and user experience are improved, but the data transmission complexity and processing requirements increase
Solution Approach 1:
The system implements feedback by transmitting touch pressure and touch area information from the user terminal to the receiving terminal. This feedback mechanism allows the TV to display visual indicators corresponding to the user's touch actions, improving control precision and user experience. The feedback loop enhances the interaction between the two terminals.
Data Source
AI summary
A system for linking and controlling terminals is disclosed. A user terminal includes an image unit configured to output image data corresponding to a first image to be shared with a receiving terminal viewed by a user of the user terminal, and a signal unit configured to transmit the image data outputted from the image unit and position information of a touch input touching the user terminal to the receiving terminal. Here, the position information is position information of the touch input touching the user terminal at a preset pressure level or lower or with a preset contact area or smaller, and is displayed on the receiving terminal in an image form.
