Display Apparatus Input Source Identification via Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems where a mobile communication terminal and a display apparatus are communicably connected, it is difficult to determine which device has been used to input an operation on shared content, leading to user confusion.
Innovation Solution
Incorporating an operation input device, an acquisition device, and a display device in both the mobile communication terminal and the display apparatus to track and display which device has inputted an operation, by exchanging input information through Bluetooth or USB communication, and highlighting or dimming screens to indicate the active input source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation input is enabled from both mobile communication terminal and display apparatus, then operability is improved, but it becomes difficult to grasp which apparatus has been used to input the operation
Solution Approach 1:
The patent implements a feedback mechanism where the system notifies the user which apparatus (mobile communication terminal or display apparatus) has received the operation input. This is achieved by displaying notification information on both apparatuses indicating the input source, thereby providing real-time feedback about the operational state and resolving the confusion about which device is actively receiving inputs.
2Adaptability or versatility
If the same content is displayed on both mobile communication terminal and display apparatus, then accessibility is improved, but it becomes difficult to distinguish the active input device
Solution Approach 1:
The patent utilizes visual differentiation through color changes or display state modifications to indicate which apparatus is the active input source. By changing the display state (such as highlighting, color coding, or visual emphasis) on the apparatus that received the operation, the system makes it easily distinguishable from the other apparatus displaying the same content, thereby solving the detection difficulty.
Data Source
AI summary
A display apparatus capable of executing content of a mobile communication terminal in cooperation with the mobile communication terminal when the display apparatus is communicably connected to the mobile communication terminal is disclosed. The display apparatus comprises: an operation input device for inputting an operation on the content in the display apparatus; an acquisition device for acquiring input information, which indicates that the operation on the content has been inputted in the mobile communication terminal, from the mobile communication terminal; and a display device for showing that the operation on the content has been inputted in the mobile communication terminal when the acquisition device acquires the input information from the mobile communication terminal.
