The World Wide Web is a great platform for asynchronous communication such as email and message boards and extended into media posting and sharing. With the rise of broadband, more powerful computers, always on and connected mobile devices, synchronous communications have become more viable. Streaming media, audio and video conferencing and realtime chat give us the ability to create new forms of live interactive experiences for participants.

In this course, we'll focus on the types of content and interaction that can be supported through web based and live interactive technologies as well as explore new concepts around participation. Specifically, we’ll look at new and emerging platforms on the web such as HTML5, WebSockets and WebRTC using JavaScript and Node.js.

Experience with web technologies are (HTML and JavaScript) are helpful but not required. ICM level programming experience is required.


Grades will be determined according to the following breakdown:


It is expected that everyone in the class will create and maintain a blog for their assignments.

Be sure to enter your name, preferred email address and the URL to your blog on this Google Doc. (Note: You must be using Google Docs with your NYU login in order to edit this document).

Laptops and Mobile Devices

I think laptops and mobile devices are a valuable tool for use in the classroom; unfortunately, they can very easily be a distraction. We are going to be exploring a variety of models for live interaction online and therefore laptops and mobile devices will prove very useful not to mention for taking notes and following along with examples. We should though be courteous to one another though and when we have outside guests, during discussion or student presentations laptop and phone use should be avoided.

Weekly Assignments

We will have weekly assignments that are relevant to material from the previous class. Due to the nature of the assignments, it is likely that you will want to work with other students as well as participate with the projects of your fellow students as testers.

Attendance and Tardiness

Attendance is mandatory. Please inform me via email if you are going to miss a class. Habitually showing up late for class or absences will adversely affect your grade. Two lates equals one absence and two unexcused absences will lead to a failing grade.

Class Participation

As if I haven't stated this enough. This class will be participatory, you are expected to participate in discussions and give feedback to other students both in class and participate with their projects. This (along with attendance) is 20% of your overall grade.

Group Project

Starting on the 3rd class, we will have weekly group project presentations. I will divide the class up into groups and each week one or two groups will be expected to present and have the class test a project utilizing technology from the previous class. Some ideas are to reimagine chat with emoji, develop a multiplayer game, put on a live interactive game show, and so on.

Final Projects

Class will culminate final projects. It is expected that these will be both technology and concept driven.


I will periodically assign readings (handouts and/or online articles).

Class Schedule

Class 1:

Introductions What is the "live" web? (Synchronous vs. Asynchronous)
HTML5 and Client Side JavaScript: HTML Basics, CSS Basics, JavaScript 101, and Media Elements
HTML Basics
CSS Basics
CSS Basics - Better Organization
JavaScript DOM Basics

  • Add your name, preferred email address, and blog URL to this Google Doc. (Note: You must be using Google Docs with your NYU login in order to edit this document).
  • If you want more basic JavaScript, go through's JavaScript Essential Training
  • Using HTML5's video or audio tags along with JavaScript, create an interactive self portrait. Link to it on your blog.
  • Write a blog post detailing the last "live" media you consumed. Answer these questions: What was it? Why did you consume it "live" or in real time? How was your relationship to the media or others affected through the "live" consumption of it? What was missing in your experience?

  • Class 2:

    JavaScript 102: Becoming Live AJAX, and WebSockets
    Serverside JavaScript: Node.js
    The foundation: Chat
    Forever - (Will make your life better!)
    Virtual Private Servers with Digital Ocean
    Unix Essential Training: Logging in and using the command prompt
  • Get up and running with Node.js on Digital Ocean and the example Chat Application. Try to extend it a bit, make it better, more fun.
  • Put your self-portrait up on the server as well. Link to it from a blog post so we can all look at them in class.

  • Class 3:

    Transmitting Other Data Types: Collaborative Drawing, Mouse Events, Other data: Notes
    The Canvas
    JavaScript 103: Objects and JSON
    p5.js with Sockets
    Class Zoom Recording
    Example code from class
  • Improve on the example, send a different type of event to the server and to the clients. This could be a collaborative drawing program or a means to control other people's experience.
  • Email me your NetID and Digital Ocean Server IP and I'll setup to point to your server. We'll need this done for next class so the sooner the better!

  • Class 4:

    The Live AV Web: HTML5 Audio and Video with WebRTC and HTTPS
    Code from class
    Class Recording
  • Get up and running with HTTPS
