Introduction and Overview

Sunbird currently supports Question Sets and Videos separately. However, we have learned that engagement with videos is much higher if questions can be placed inside videos. Once the videos are made interactive, the learning experience is much more enjoyable for the end user.

With support for Interactive Videos in Sunbird, we will have the capability to:

1. Make any video interactive: The goal is to design this in such a way what any available video can be made interactive by adding any question set at any timestamp in the video.

2. Publish interactive videos as a new form of content: This will enable teachers to leverage interactive videos to improve the experience for learners

3. Analyse interactions at a deeper level: The interactive video platform will provide an exhaust for telemetry and analysis which will allow data about engagement at a very detailed level.

Proposal

To enable interactive videos on Sunbird, we will leverage as many existing components as possible to enable quick and efficient development. Currently, we envision these main workstreams:

• Asset Model: An asset model will be enhanced to support interception points in content. We will start with videos, but this work will be done keeping in mind that in the future, we will extend this concept to support interactive content of any kind. In fact, we could, in the future, extend the concept even to more than two assets. For example, a child could read a few pages in a document (PDF), watch a quick video to visually understand the concept, and quickly practice what she learnt, all in sequence.

• Creator: A new content creation UI will be created to enable any user of Sunbird to create interactive videos. They will pick from any preexisting video, and be able to add any existing question sets at any timestamp in the video. A possibility here is to allow for creation of new question sets inside the creation process.

• Player: We do not need a new consumption experience for interactive videos. The current video player can be enhanced to support the interactive video content models

• Telemetry and Analysis: Detailed interaction events will be captured when an interactive video is consumed. This will include, but is not limited to video playback quality, scrubbing (Pause, Rewind and Fast Forward) behaviour, question events (answering, skipping, etc) and score related data.

Requirement Specifications

Here are the use cases we are currently targeting

• Interactive Video Creation: As a creator, I need a simple interface with good User Experience to be able to create interactive videos.

• Interactive Video Consumption: As a learner/viewer, I would like to be able to view interactive videos similar to any other content type on Sunbird. When I log in and navigate to my available content, I should be able to find interactive videos easily. When I choose an interactive video, the experience should be engaging and rewarding.

• Associated user stories 

• Non-functional requirements

• Localization requirements  

• Telemetry requirements

• Dependencies

• Impact on other products

• Impact on existing data  

Interactive Video Creation

The process to create interactive videos should be smooth and seamless. For V1, users cannot upload interactive videos, but can only use existing videos to enhance them with question sets for interactivity

Interactive Video Consumption

This scenario describes the MVP for a user playing an interactive video. The expectation here is that users can find and consume interactive videos similar to any other sort of content on Sunbird.

Creator Dashboard

I believe we should also have a section on “Creator Dashboard” where creator can see metrics for their interactive videos, generate insights about what to improve.

Exception Scenarios

Wireframes

Creator Interface V1

• On uploading video content on the Sunbird platform, the user will get an option to make the video interactive

• After selecting the <Make Interactive> option, the ability to add a question set to the video will be available to the user

• On clicking <Add a new question set>, the browse question set dialog box will pop up from where the user can select a question set from the existing question sets created

• The question set will be added at the same timestamp where the user had clicked on the <Add a new question set> button. They can edit the timestamp in the bottom left corner of the dialog box

• The user can browse through the project→textbook→chapter from which they want to select a question set to add

• Once they select all details, the list of all questions sets will appear

• The user can select the question set and then click on <Add Question Set> to add it to the video

• This will add the selected question set to the respective timestamp

• The added question set will appear on the right side of the player with the timestamp and ability to edit (will open the question set browsing dialog box) and delete the question set

• A blue marker will be visible on the progress bar of the player at the timestamp where the question set is added

• User can also drag and move the marker on the progress bar to change the timestamp of the question set

• On clicking the question set on the right side of the player, a preview of the question set will be visible to the user

• User can submit the question set for review once they have added all desired question sets

Player Interface V1

• Timestamps with question sets overlayed will be bookmarked with a green marker

• The viewer will have the option to skip and revise a question set

  • <Skip> - This will allow you to bypass the question set and proceed with the video

  • <Revise> - This will start playing the video from the last bookmarked timestamp. In case the first question set is revised, the video will start from the beginning

• On submitting the answer, the viewer will have to click on <Proceed> for continuing with the video

For Future Release

1. In future releases, we will aim to enhance all types of content with interactivity as outlined in the Proposal section above So instead of just an “interactive video”, we will have “interactive content”, which will be a very powerful learning tool for the user.

2. We will allow for users to add interactivity to a video in the uploading process itself.

3. We will allow for different question types: Match the Following, Multiple Answer Questions, and so on.

4. We will allow creators to make content interactive within a specific context (e.g.: collection). For example, add a question set interception in a video only within a specific course. The video will be a normal one when consumed as an independent resource.

Localization Requirements

This task does not have any special localization requirements. The level of localization supported will be the same as the level of localization of the underlying tools: video player, QuML player, and Video Creation.

Telemetry Requirements

We will collect click level interaction when an interactive video is played. Interactive Videos will emit all telemetry that is already emitted by the included components: the video player, and the QuML player. In addition to this, some custom events specific to the behaviour of interactive videos will be defined.

Key Metrics

The main metric to track here will be engagement with the interactive video. Some of the metrics we can use for this purpose are listed below

The goal will be to understand which interactive videos are working better, which are not doing so well, and in general, understand what makes for a good interactive video. For example:

1. What is the sweet spot of interception point for driving engagement, i.e. do questions work better in the first 1 minute or after 3 minutes or after 5 minutes?

2. How long should my video be: 3-5 minutes or 8-10 minutes? How does this change depending on subject, age group, class, etc?

For example, NROER / NCERT has many videos which are 45 minute long (recorded lectures). I want to know how many pieces should I make of them to make them of ideal length (available from 2) and where to put the questions (available from 1).
