Event Segmentation Paradigm

Event Segmentation Paradigm using movie files. Developed by Node.js and JavaScript.

Usage

Install dependencies

Clone this repository. Open a terminal from the project directory and run:

npm install

Preparing video files

For the copyright issues, I excluded video files used in the our experiment. Therefore, please prepare your own video files and follow the guide below:

1. Encode the video file: Your video would be played on a web browser (i.e., Google Chrome). Therefore, the videos should be converted into a supported video format. I recommend encoding video files into MP4 H.264 (ACC audio).
2. Rename the video file: Rename all video files in a format like [number].mp4 (e.g., 1.mp4, 5.mp4, ...).
3. Place videos inside the static file directory: Create a directory named "videos" inside the ./files directory. Place all video files inside the ./files/videos directory.
4. Update "videoIDs" variables in index.js file: Open index.js file. Find videoIDs variable inside a function named getRandomVideo (near line 45). Update the variable with respect to the your video IDs. For example, if you have five video files: 1.mp4, 2.mp4, 3.mp4, 4.mp4, 5.mp4, then update the code like this and save:

...
    if (typeof videoList === "undefined") {
        let videoIDs = [1, 2, 3, 4, 5]; // Please update this part when you change video files.
        sID_Videos_Map.set(sID, videoIDs);
        videoList  =  sID_Videos_Map.get(sID);
    }
...

Create /data directory

Create a directory called "data" at the project directory.

Run the experiment

Find an IP address of the computer where you run the server script. Open a terminal from the project directory and run:

node index

At the computer where the actual event segmentation paradigm would be presented, Open Google Chrome and connect to [IP address of the server]:8000. For example, if the IP address of your server computer is 127.0.0.1, then connect to

127.0.0.1:8000

from the experimental computer.
