Avatar Synchronization with Content Rhythm in Video Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display devices for shared experiences, such as live concerts, fail to adequately synchronize avatar movements with the music, leading to discomfort due to rhythmic desynchronization and continuous movement deviations.
Innovation Solution
A video display device with a communication processing unit, avatar generation processing unit, movement information detection processing unit, and control unit that synchronizes avatar movements with the detected rhythm of the content, ensuring the avatar's movements align with the music, thereby enhancing the shared experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If avatar movements are generated without synchronizing to the rhythm of the content, then device complexity is reduced, but user comfort deteriorates due to rhythmic desynchronization
Solution Approach 1:
The system detects rhythm information from the content and uses it as feedback to adjust and synchronize avatar movements. The rhythm detection processing unit continuously monitors the content's rhythm and feeds this information back to the avatar generation processing unit, which then adjusts the avatar's movements to match the detected rhythm, eliminating user discomfort caused by desynchronization.
Solution Approach 2:
The system performs preliminary rhythm detection and analysis before generating avatar movements. By detecting the rhythm information in advance and preparing synchronized movement patterns, the system ensures that avatar movements are already aligned with the content's rhythm when displayed, preventing user discomfort before it occurs.
2Object-affected harmful factors
If avatar movements are synchronized to the rhythm of the content, then user comfort is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system divides the avatar generation process into separate functional units: a rhythm detection processing unit that extracts rhythm information from content, and an avatar generation processing unit that applies this rhythm information to generate synchronized movements. This segmentation allows each unit to specialize in one task, improving efficiency while maintaining synchronization.
Solution Approach 2:
The rhythm detection processing unit serves multiple functions: it detects rhythm from various types of content (music, speech, ambient sound), extracts temporal patterns, and provides this information to the avatar generation unit. This multi-functionality reduces overall system complexity by using a single versatile component rather than multiple specialized ones.
3Measurement precision
If rhythm detection processing is added to synchronize avatar movements, then measurement precision of movement timing is improved, but device complexity increases
Solution Approach 1:
The rhythm detection processing unit acts as an intermediary between the content input and the avatar generation process. It extracts rhythm information from the content and transforms it into a format that the avatar generation unit can use to synchronize movements. This intermediary layer simplifies the overall system by providing a standardized interface for rhythm synchronization.

AI summary
A video display device for displaying a video of distributed content and an avatar, which is a computer-generated image, on a display screen to overlap each other, includes: a communication processing unit connected to a network; an avatar generation processing unit that generates an avatar of another person from avatar information received through the communication processing unit; a movement information detection processing unit that detects movement information of a continuous movement associated with the video of the content received through the communication processing unit; a display unit that displays the content received through the communication processing unit; and a control unit. The avatar generation processing unit generates an avatar by adding the movement information detected by the movement information detection processing unit to a movement of the generated avatar. The control unit displays the avatar generated by the avatar generation processing unit on the display unit to overlap the content.
