Display Account Highlighting via External Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require users to manually log in with a desired user account each time, especially in shared devices like TVs, which is cumbersome and reduces user convenience, particularly when multiple accounts are involved, such as in family settings.
Innovation Solution
A display apparatus that determines the most likely user account to log in by communicating with external devices through short-range and long-range communication, displaying user accounts differently based on signal strength, network connection, and login history, allowing easy identification and selection of the preferred account.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually log in with a desired user account each time on a shared device, then login security and accuracy are improved, but user convenience and operation time deteriorate
Solution Approach 1:
The system performs preliminary actions by detecting external devices and pre-loading user account information before the user actually needs to log in. The display apparatus proactively identifies registered devices, retrieves associated account credentials, and prepares the login interface in advance, eliminating the need for users to manually enter credentials each time.
Solution Approach 2:
The system enables self-service by automatically detecting external devices, identifying registered user accounts, and completing the login process without requiring manual user intervention. The display apparatus serves itself by maintaining a database of registered devices and accounts, automatically matching detected devices with their corresponding accounts, and facilitating seamless login.
2Quantity of substance
If the display apparatus displays all user accounts equally, then completeness of information is improved, but ease of identification and selection deteriorates
Solution Approach 1:
The system applies local quality by differentiating the display characteristics of user accounts based on their association with detected external devices. Accounts linked to registered devices are displayed with distinctive visual properties such as highlighting, different colors, or special icons, while other accounts maintain standard display characteristics. This localized differentiation makes it easy for users to identify their accounts among multiple options.
3Adaptability or versatility
If the display apparatus communicates with multiple external devices to identify user accounts, then personalization and convenience are improved, but device complexity and communication requirements worsen
Solution Approach 1:
The system implements universality by designing the communication module to handle multiple types of external devices (smartphones, tablets, wearables, PCs) through a unified interface and protocol. The display apparatus maintains a universal database structure that can store and manage user account information associated with various device types, and the detection mechanism works across different device categories without requiring separate specialized systems for each device type.
Data Source
AI summary
A display apparatus is provided. The display apparatus includes communication circuitry configured to communicate with an external device, a display configured to display at least one application, an input portion configured to receive an execution command for the at least one application from a user, memory, including one or more storage media, storing instructions, and a processor communicatively coupled to the communication circuitry, the display, the input portion, and the memory, wherein the instructions, when executed by the processor, cause the display apparatus to control the display to display a plurality of user accounts that were previously logged in in response to receiving the execution command, and control the display to display at least one of the plurality of user accounts differently from remaining user accounts based on communication information with the external device.
