Physical Computing is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. In this course, we take the human body as a given, and attempt to design computing applications within the limits of its expression.
To realize this goal, you’ll learn how a computer converts the changes in energy given off by our bodies (in the form of sound, light, motion, and other forms) into changing electronic signals that it can read and interpret. You’ll learn about the sensors that do this, and about simple computers called microcontrollers that read sensors and convert their output into data. Finally, you’ll learn how microcontrollers communicate with other computers.
To learn this, you’ll watch people and build devices. You will spend a lot of time building circuits, soldering, writing programs, building structures to hold sensors and controls, and figuring out how best to make all of these things relate to a person’s body.
Safety Requirement: If you plan to use the shop at 370 Jay, some time in weeks 1 – 3 attend a tool safety session in the shop! Even if you are an experienced fabricator, everyone is required to take a safety session if planning to use or be in the shop.
- 45 – 60 minutes discussion, questions from the homework, presentation and discussion of projects, discussion of reading material and other issues.
- 10 minutes break
- 60 – 90 minutes introduction to new material. Your instructor will introduce the week’s material and demonstrate that week’s labs. Feel free to bring your own components and build alongside the instructor if you find it helpful. This part of the class is also very interactive, so be prepared by reviewing the class notes in advance. Speak up when you have questions or want clarification on anything discussed or shown in the class.
The assignments in this class consist of weekly lab assignments throughout the semester; readings, discussion, and class participation; and three project assignments in which you’ll build interactive devices.
There are lab assignments for most weeks of the semester. These are practical exercises that will help you to learn the technical material of the class. Each week you should review the topic notes or videos explaining that week’s materials, then do the labs, and write about your progress, your failures, and your questions. Class time most weeks will start with your questions and progress from the labs.
You’ll complete three projects in this class. The briefs for these are on the assignments page. The material in the labs will provide the techniques you need, and the class discussion will help you to come up with the ideas for each of these. You’ll show your project assignments in class in weeks 5, 10, and 14. You will be expected to document your projects on your blog as well.
You’ll also be expected to document your progress in the class online in a regular blog as you go. At a minimum, you’re expected to summarize any insights you have in each week’s lab assignments, and to document your production projects and technical research thoroughly. You can find guidelines for good documentation, and several examples, on the Journals & Documentation page.
Topic notes to be covered each week are linked on that week’s class page. Read each week’s material before class and prepare questions. There are videos that demonstrate the labs as well. The videos cover the same material as the written notes, so you can learn from whichever form you find most useful.
You’ll also be assigned some short readings to generate discussion about physical interaction design, application ideas, and other topics. These provide context and background inspiration.
A longer list of both technical and conceptual source material can be found on the Books page.
Prepare for class in advance. Review the material to be covered that week, and come to class with questions prepared about that class’s material. If you have no questions, be prepared to show your work.
Commenting on each others’ work
Supporting your classmates through feedback on their work is an important part of the class, and an important part of your participation grade. When watching your classmates present their work in class, we’ll make some time for verbal comments, but you should take written notes on their presentations as well. Offer suggestions on what they did well and should continue doing, what they should stop doing, and what they could add to their work and/or their presentation to make it better. Share your notes with your classmates at the end of class. You’ll be getting the same notes from your classmates, so write in the same voice in which you’d like to hear feedback on your own work.

Parts and Materials Used in Class
You’ll be building a lot of projects in this class, both electronic and mechanical devices. All of your projects will be rough drafts of the interaction you imagine. The electronic exercises will be demonstrated with Arduino microcontrollers and a variety of sensors and actuators. The details of what parts you need can be found on the Parts and tools guide 2020 page. The ITP shop and equipment room stock parts for you to “try before you buy.” They’re there for you to get to know a sensor or part to see if it will do what you need. Please don’t hoard parts from the shop, so that others can use them as well. Take only what you need for a particular project.
The most important thing you can do is arrive to each class on time and be prepared to actively participate, with questions, stories of setbacks or successes you encountered in the lab, and interesting material and events related to pcomp you’ve found. Each week, you should put in adequate time to really digest and then apply the material. We’re unimpressed by last-minute cramming. Floor 4 is the best place to do your class work, as you’ll be surrounded by your peers tackling the same topics, and you’ll have access to second-years, residents, and full-time faculty. Our time together each week, and your access to the 4th floor, is what distinguishes studying pcomp at ITP from, say, just reading the internet.

Participation & Attendance
Showing up on time, engaging in the class discussion, turning in assignments on time, and offering advice and critique on other projects in the class is a major part of your grade. Please be present and prompt. Lateness will hurt your grade. If you’re going to be late or absent, please email your instructor in advance. If you have an emergency, please let your instructor know as soon as you can.
Personal Device Use
The quality of the class depends in large part on the quality of your attention and active participation, so please respect that. Silence any devices that you’re not actively using in class, and turn off notifications on them or on programs so as not to disrupt the discussion. If you have an emergency that might require you to leave during class, please tell your instructor ahead of time.
Statement of Academic Integrity
Plagiarism is presenting someone else’s work as though it were your own. More specifically, plagiarism is to present as your own: A sequence of words quoted without quotation marks from another writer or a paraphrased passage from another writer’s work or facts, ideas or images composed by someone else.
Statement of Principle
The core of the educational experience at the Tisch School of the Arts is the creation of original academic and artistic work by students for the critical review of faculty members. It is therefore of the utmost importance that students at all times provide their instructors with an accurate sense of their current abilities and knowledge in order to receive appropriate constructive criticism and advice. Any attempt to evade that essential, transparent transaction between instructor and student through plagiarism or cheating is educationally self-defeating and a grave violation of Tisch School of the Arts community standards. For all the details on plagiarism, please refer to page 10 of the Tisch School of the Arts, Policies and Procedures Handbook.
Statement on Accessibility
Please feel free to make suggestions to your instructor about ways in which this class could become more accessible to you. Academic accommodations are available for students with documented disabilities. Please contact the Moses Center for Students with Disabilities at 212 998-4980 for further information.
Statement on Counseling and Wellness
Your health and safety are a priority at NYU. If you experience any health or mental health issues during this course, we encourage you to utilize the support services of the 24/7 NYU Wellness Exchange 212-443-9999. Also, all students who may require an academic accommodation due to a qualified disability, physical or mental, please register with the Moses Center 212-998-4980. Please let your instructor know if you need help connecting to these resources.
