Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current educational technologies lack effective methods for students to interactively engage with video content, particularly in flipped classrooms, where students need to mark important points or questions during video lectures without a straightforward way to track and manage these annotations over time.

Innovation Solution

An information processing apparatus that allows students to paste sticky notes on videos, which are then automatically removed and displayed on a timeline, enabling teachers to assess student engagement and understanding by visualizing the annotations over the video's time axis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If sticky notes are pasted to videos for student interaction, then student engagement with video content is improved, but managing and tracking annotations over time becomes difficult

Engineering Contradiction:

Improvestudent engagementVSAvoidannotation management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the sticky note annotations from the video playback interface and places them on a separate timeline display. This separation allows students to view videos freely with sticky notes during playback, while the timeline provides an organized overview of all annotations chronologically, solving the management complexity issue

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The timeline acts as an intermediary between the video playback and the sticky note annotations. It mediates by displaying annotations in chronological order with timestamps, allowing teachers and students to track when annotations were made without interfering with the video viewing experience

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If sticky notes are displayed on video during playback, then interactive engagement is enabled, but tracking annotations over time becomes complex

Engineering Contradiction:

Improveinteractive engagementVSAvoidtracking annotations

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The timeline continuously displays all sticky note annotations in chronological order, providing an ongoing record of student interactions with the video content. This continuous display eliminates the need to manually track or search for annotations, as they are automatically organized by timestamp

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The timeline provides immediate visual feedback to teachers about student engagement with video content. By displaying annotations with timestamps, teachers can quickly assess which parts of the video generated student interest or confusion, enabling timely intervention without time-consuming manual tracking

Inventive Principle:

Principle #23Feedback

AI summary

An information processing apparatus includes a pasting unit that plays a video and pastes at least one sticky note to the video; a removal unit that removes the sticky note pasted by the pasting unit from the video in a case where a predetermined condition is satisfied; and a display unit that displays the sticky note removed by the removal unit on a time axis so that a date and time at which the sticky note removed by the removal unit is pasted to the video is indicated on the time axis so as to be checked.
