Display Controller Identifying Capable Input Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses do not provide information about available input devices, leading to user inconvenience when multiple devices transmit input signals, as they do not distinguish capable from incapable devices for remote control.
Innovation Solution
A display apparatus with a signal receiver, display unit, and controller that identifies and displays connection information for input devices capable of controlling the apparatus, using UI objects to differentiate between capable and incapable devices, and supports various communication methods like Bluetooth, Wifi, and Zigbee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus receives input signals from multiple input devices, then the functionality and control options are improved, but the user cannot identify which devices are capable of controlling the apparatus, leading to confusion and inconvenience
Solution Approach 1:
The display apparatus provides visual feedback by displaying connection information on the display unit, showing which input devices are connected and capable of control. This feedback mechanism resolves the contradiction by enabling users to identify controllable devices among multiple connected devices, maintaining ease of operation while supporting multiple control options
Solution Approach 2:
The display unit acts as an intermediary between the multiple input devices and the user. It presents connection information that mediates the interaction, allowing users to understand which devices can control the apparatus without direct communication between devices and users, thus resolving the identification problem
2Loss of information
If the display apparatus displays information about all connected input devices, then complete information is provided, but the interface becomes complex and difficult to interpret
Solution Approach 1:
The system extracts and displays only the essential connection information about input devices on the display unit, rather than showing all possible device attributes. This extraction principle maintains information completeness while avoiding interface complexity by presenting only the most relevant identification data
Solution Approach 2:
The connection information is segmented and presented in a structured format on the display unit, dividing the information about multiple devices into individual, manageable units. This segmentation allows complete information to be displayed without creating interface complexity, as each device's information is clearly separated and organized

AI summary
A display apparatus and a control method thereof are provided. The display apparatus includes: a signal receiver which receives an input signal corresponding to a user's input, from at least one of a plurality of input devices receiving the user's input; a display unit which displays thereon information on the plurality of input devices; and a controller which identifies whether the plurality of input devices are capable of receiving the user's input, and displays on the display unit connection information displaying at least one of the plurality of input devices which is capable of receiving the user's input. Accordingly, information on a plurality of input devices which are capable of controlling the display apparatus are displayed on the apparatus.
