Solution Overview

Problem

Existing virtual reality systems lack intuitive control over comment filtering in video playback, as comments overlay and scroll across the video, making it difficult for users to manage and visualize filtered and unfiltered comments effectively.

Innovation Solution

A system with a movable filter line that divides the video into two areas, where comments are displayed before filtering in one area and filtered out in another, allowing users to set filtering rules based on keywords, user accounts, semantic analysis, or regular expressions, and providing visual feedback and sensitivity control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If comments are displayed overlaying and scrolling across the video without filtering, then all user comments are visible and accessible, but it becomes difficult for users to manage and visualize filtered and unfiltered comments effectively

Engineering Contradiction:
Improvevisibility of comment filteringVSAvoidcontrol over comment filtering
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display area is segmented into a first area showing unfiltered comments and a second area showing filtered comments. This segmentation allows users to simultaneously view both filtered and unfiltered comments in distinct regions, resolving the contradiction by providing visual separation while maintaining access to all comment information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A filter line is introduced as an intermediary element that visually separates and connects the first area (unfiltered comments) and the second area (filtered comments). The filter line acts as a mediator that users can interact with to control the filtering process, making the filtering mechanism visible and controllable while maintaining information visibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a filter line is introduced to separate filtered and unfiltered comments, then user control and visibility of comment filtering is enhanced, but the device complexity increases

Engineering Contradiction:
Improveuser control and visibilityVSAvoidfiltering system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The filtering function is extracted and visualized as a separate filter line element that can be independently controlled and manipulated. This extraction allows the complex filtering logic to be represented by a simple visual interface element, enhancing user control without proportionally increasing overall system complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The filter line and associated areas utilize visual distinctions (such as different regions or visual markers) to indicate filtered versus unfiltered states. This visual encoding simplifies the user interface by providing intuitive feedback about filtering status without requiring complex controls or displays.

Inventive Principle:
Principle #32Color changes

AI summary

An apparatus configured to, in respect of a video provided to a user and wherein a plurality of comments are displayed such that they scroll across the video, based on the comments and one or more comment filtering rules; provide for comment filtering as each of the plurality of comments scrolls to meet a filter line, wherein the filter line extends across at least part of the video to define a first area overlaying the video and a non-overlapping second area overlaying the video, such that in the first area the plurality of comments are provided for display scrolling therethrough towards the filter line prior to comment filtering and in the second area the plurality of comments are provided for display with any comments of the plurality of comments that satisfy the one or more comment filtering rules removed from display.
