Solution Overview

Problem

Users viewing videos lack interactivity as they cannot connect with others watching the same content, limiting true collaborative viewing experiences.

Innovation Solution

A method and apparatus that determine a user's viewing progress and match them with a projection room based on similar viewing times, sending invitations to access and interact with others in real-time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users view videos individually on video detail pages, then each user can access video information independently, but user interaction and social connection are lost

Engineering Contradiction:
ImproveIndependent video accessVSAvoidSocial connection information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces a projection room as an intermediary space that connects multiple users viewing the same video. The projection room serves as a mediator between individual users, enabling social interaction while maintaining independent video access. Users are matched based on viewing progress and invited to join projection rooms, thus recovering social connection information without compromising individual viewing convenience

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If users are matched with projection rooms based on viewing progress, then user interaction is enhanced, but system complexity increases

Engineering Contradiction:
ImproveSocial connection informationVSAvoidMatching system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses viewing progress as a key parameter for matching users into projection rooms. By changing the matching criterion from random or manual to progress-based automated matching, the system enhances social connection recovery while managing complexity through algorithmic approaches. The server automatically matches users based on their viewing progress parameters, reducing the need for complex manual intervention

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If real-time viewing progress tracking is implemented, then accurate matching is achieved, but data processing load increases

Engineering Contradiction:
ImproveViewing progress accuracyVSAvoidData processing energy
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements a system where users' viewing progress is automatically tracked and reported to the server without requiring additional user actions. The client device self-services by monitoring its own viewing progress and transmitting this data when appropriate (e.g., when reaching certain progress milestones). This approach achieves accurate measurement while reducing continuous data processing load, as data transmission is event-driven rather than continuous

Inventive Principle:
Principle #25Self-service

AI summary

This application provides a method and apparatus for view videos. The method includes determining a viewing progress of viewing a target video by a user, determining a target projection room associated with the target video based on the viewing progress; and sending the user a video viewing invitation to access the target projection room. This implements that a projection room with a similar progress is matched for the user, so that the user can view a video with another user together.
