Engineering Contradiction Analysis
1Length of moving object
If mobile devices are used to access services, then portability is improved, but display screen size is reduced
Solution Approach 1:
The patent merges the mobile device and display device into a unified system where the mobile device acts as a remote controller for the display device. The mobile device's touch screen and the display device's larger screen work together to provide both portability and large-screen functionality simultaneously.
Solution Approach 2:
The patent introduces a touch area recognition mechanism as an intermediary between the mobile device and display device. By detecting touch areas on the display device and mapping them to corresponding functions on the mobile device, the system enables seamless interaction that bridges the gap between small portable screens and large display screens.
2Measurement precision
If touch sensing is added to identify touch areas, then user interaction precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the display device's touch screen serve multiple functions: it acts as both the display interface and the input interface for controlling the mobile device. The same touch screen that displays content also detects touch areas to identify user intentions, eliminating the need for separate sensing components.
Solution Approach 2:
The display device uses its own existing touch screen capabilities to identify touch areas and control the mobile device, rather than requiring additional external sensors or complex sensing systems. The system serves itself by utilizing its inherent touch functionality for dual purposes.
Data Source
AI summary
An operating method of the display device includes detecting, through at least one sensor, at least one sensing value corresponding to the at least one sensor, identifying a touch area on the display device that is touched by a mobile device, based on the at least one sensing value, receiving status information about an operation that is being executed by the mobile device, from the mobile device, and performing a function corresponding to the identified touch area, based on the received status information.
