Pointer Display on External Screen via Terminal Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to select applications or functions on an external device while watching a video output, as the position of their finger or input device is not visible on the external screen, requiring them to alternate attention between the terminal and the external device.
Innovation Solution
A method and apparatus that transmit a pointer displaying signal from a terminal to an external device, allowing the pointer to be displayed on the external device based on detected user input, enabling users to interact with the external device without looking at the terminal.

Engineering Contradiction Analysis
1Area of stationary object
If video output is shared between terminal and external device, then user can watch video on larger screen, but user cannot see pointer position on external device
Solution Approach 1:
The patent introduces a pointer as an intermediary visual element that mediates between the input device (electronic pen or finger) and the display screen. The pointer is displayed on the external device screen to indicate the current input position, allowing users to see where their input is registered without looking at the terminal. This resolves the information loss by providing a visual intermediary that bridges the gap between the hidden input position and the visible output.
2Ease of operation
If user interacts with external device without looking at terminal, then user convenience improves, but pointer position detection becomes difficult
Solution Approach 1:
The system implements feedback by continuously displaying the pointer position on the external device screen in real-time as the user moves the electronic pen or finger. This visual feedback allows users to see the consequence of their input actions immediately, enabling them to interact with the external device confidently without looking at the terminal. The feedback loop closes the information gap between user action and system response.

AI summary
The present invention relates to a method of displaying a pointer on an external device sharing an output video with a terminal, and an apparatus thereof. A method of controlling display of a pointer by a terminal so that the pointer is displayed on an external device according to an embodiment of the present invention includes transmitting an output video of the terminal to the external device, if a predetermined request exists; detecting a sensing value according to a input performed on a display area; generating a pointer displaying signal used for displaying a pointer at a position corresponding to a position where the detected sensing value is detected on the external device based on the detected sensing value; and transmitting the generated pointer displaying signal to the external device. According to the present invention, since a pointer is displayed on an external device sharing an output video with a terminal, the user may execute a desired function by looking at the external device, without looking at the terminal.
