Face Recognition Display Device for Automated Media Playback Resumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital TVs experience inconvenience due to the need to log on and log out using IDs and passwords, which hinders the provision of customized services and efficient media content viewing.
Innovation Solution
A display device equipped with a camera unit for face recognition, allowing users to access customized services without additional remote controller manipulation by tracking viewing states and re-establishing media content playback from the last viewed point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face recognition technology is implemented to provide customized services, then user convenience and service personalization are improved, but device complexity and security risks increase
Solution Approach 1:
The camera unit serves multiple functions: it captures user images for face recognition, monitors viewing state to detect user absence/presence, and enables both customized service access and automated re-viewing. This multi-functionality reduces the need for separate authentication devices while improving user convenience.
Solution Approach 2:
The system automatically performs face recognition, viewing state monitoring, and re-viewing execution without requiring manual user input. The TV detects user presence/absence and autonomously resumes or stops content playback, eliminating the need for users to manually log in or control the remote.
2Productivity
If continuous monitoring of viewing state is performed, then automated re-viewing service is improved, but energy consumption and processing load increase
Solution Approach 1:
The viewing state monitoring operates periodically rather than continuously. The camera captures user presence/absence at intervals, and the control unit checks viewing state at discrete moments. This periodic operation reduces energy consumption while still enabling automated re-viewing when users return.

AI summary
A method for operating a display device according to an embodiment includes acquiring an image of a plurality of users, recognizing a plurality of faces respectively corresponding to the plurality of users from the acquired image, checking a viewing state of media content for each user, when the plurality of users respectively corresponding to the plurality of recognized faces are registered users, acquiring viewing information corresponding to at least one of the plurality of registered users of which the viewing state has been changed from a viewing maintaining state in which the media content is viewed to a not-viewing state in which the media content is not viewed, and performing a re-viewing function on the basis of the acquired viewing information when a face of the user of which the viewing state has been changed is re-recognized.
