Fall 2009Physical 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 interpret. You'll learn about the sensors that do this, and about very simple computers called microcontrollers that read sensors and convert their output into data. Finally, you'll learn how microcontrollers communicate with other computers. Physical computing takes a hands-on approach, which means that you 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 expression.
Please note the dates of your class. Due to the Thanksgiving Holiday and the Legislative day, there are some shifted classes. Some time in weeks 1 - 3: Attend a tool safety session in the shop The syllabus is broken down into:
Week 1CONCEPTS:
LABS: ASSIGNMENT:
BLOG: Sensor walk. Take a walk around your neighborhood, or a different one. Take a count of every interaction with a sensor you see. These might include:
Take pictures or video as appropriate, of the most interesting ones.

Week 2CONCEPTS: LABS:
ASSIGNMENT: Fantasy Device. Think of a fantasy device you've always wanted. Doesn't have to be physically possible, but it has to have a physical interface. Design what the physical interface was. Document your design on your blog, and bring it in for the class. Your mock-up doesn't have to work, and it can be made out of any materials you're comfortable with. Make this a quick sketch, just enough so that your classmates have a sense of what they would do to use your device.
Week 3PRESENT THIS WEEK:
CONCEPTS: LABS:
ASSIGNMENT: Stupid Pet Trick. Make a simple physically interactive device that uses the skills you've learned in the labs. It must respond to a physical action or series of actions a person takes, and it must be amusing, surprising, or otherwise engaging.It doesn't have to be practical, or complex, as long it shows that you understand the basics of digital and analog I/O and how to use them. If you're unfamiliar with the term "stupid pet trick," Googling the term may provide you inspiration for the tone of this project.

Week 5PRESENT THIS WEEK:
ASSIGNMENT: Media controller project. Make a physical device that controls a medium. It should control the medium in real-time, so that the user can change her actions and see changes as they affect the medium. There are lots of media: digital video, digital audio, electronic or acoustic sound, physical media like paint or ink, and others. Think about paint brushes, video mixers, musical instruments, water faucets, sewing machines -- anything that can control a medium and let you see the changes as you vary your control is fair game.'
This is a group assignment. Groups will be arranged in class this week.

Week 6CONCEPTS:
LAB:
BLOG: Observation. Pick a piece of interactive technology in public, used by multiple people. Write down your assumptions as to how it's used, and describe the context in which it's being used. Watch people use it, preferably without them knowing they're being observed. Take notes on how they use it, what they do differently, what appear to be the difficulties, what appear to be the easiest parts. Record what takes the longest, what takes the least amount of time, and how long the whole transaction takes. Consider how the readings from Norman and Crawford reflect on what you see.
Week 7CONCEPTS:

Week 8CONCEPTS: LABS: Week 9PRESENT THIS WEEK: media controller. ASSIGNMENT: Final project. Create a physically interactive system of your choice. Your focus in this assignment should be on careful and timely sensing of the relevant actions of the person or people that you're designing this for, and on clear, prompt, and effective response. Any interactive system is going to involve systems of listening, thinking, and speaking from both parties. Whether it involves one cycle or many, the exchange should be engaging.
Document your work thoroughly online as you go. Include details of all phases of the project. Include a project summary as well, explaining what the system you built is, what it does, and what purpose it's intended to serve. Your summary should introduce the project.
A few examples:
Musical Instruments. Performing music involves a sustained engagement between the performer and the instrument. The feedback fro mthe instrument has to be immediate and clear in order for the performer to continue playing. The interface has to be flexible so that the musician can exercise her creativity in playing, but has to have some boundaries so that she knows what the instrument can do and what it can't do.
Game interfaces. Like musical instruments, they involve constant back-and-forth interaction and immediate response. They are often simpler than musical instruments. In fact, the standard game controller has gotten so standard that the action of many games is artificially adapted to the needs of the controller, not the physical expressiveness of the player. Pick a specific game and see if you can change that.
Assistive devices. Whether it's something as simple as a reaching device (think of pickle pickers) or something more complex, these devices are very demanding of clear, reliable response.
Remote control systems. They require not only a clear interface, but must also return enough information on the remote system's action to let you know that you're doing the right thing. Whether it's a remote controller for your home electrical devices or a Mars rover controller, the need for clarity and good feedback are equally essential to the person who it's made for.
There are many other good applications for this project. Discuss the specifics of yours with your instructor.

GradingParticipation & Attendance: 40% Participation & AttendanceShowing up on time, engaging in the class discussion, 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. Please turn in assignments on time as well. LaptopsLaptop use is fine if you are using your laptop to present in class, or if we're in the middle of an exercise that makes use of it. Whenever classmates are presenting or we're in the midst of a class discussion, however, please keep your laptop closed. The quality of the class depends in large part on the quality of your attention and active participation, so please respect that and close your lid. Mobile PhonesPlease put them on vibrate or turn them off before you come to class unless they are part of your project. If you have an emergency that requires you to answer your phone during class, please tell your instructor ahead of time. Lab AssignmentsThere is a lab activity for nearly every class in the first half of the semester. They are very short, simple activities. These are the basic steps you need to go through to understand the principle discussed in class each week. They're designed to help you not only to understand the technical details, but also to get a feel for what the technologies we're discussing can do, so that you can incorporate them into actual applications. You should at least complete the steps outlined in the lab activity each week, so that you understand practically what it is we're talking about. Document on your blog any discoveries you make, pitfalls you hit, and details not covered in the class or the lab that you think will be useful for your fellow students and future students in this class. Production AssignmentsFor production assignments, you'll be expected to present your project in class on the day that it's due. If you're working in a group, all group members should be present, and should participate equally in the presentation. Journal & DocumentationYou are expected to keep an online journal of your progress. The purpose of the journal is twofold. First, it is a valuable way for you to communicate to your instructor that you are keeping up with the work in the class. We read the journals to see how students are doing, so you should update your journal regularly throughout the semester. At a minimum, reference to each week's work is expected, as well as reference to the readings, and thorough documentation of the production projects and technical research. Second, the journal is a way to document your work for your own use and that of others. Many ITP students have found themselves using their journals as a place to store notes, code samples, and more. Good documentation habits for this class:You may choose to document your major projects in a separate individual or group site if you choose, but you will be expected to link your site to the main site, and contribute to the class site as well nonetheless. Please avoid flash, shockwave, or other sites that are not text-searchable, as they won't show up on search engines for others to use. Blogs are great for documenting your process, as they're usually defaulted to organizing the information chronologically. However, projects summarized in a blog can be confusing. It's often worthwhile to set up a separate page or pages to summarize your projects when they're done. You should document your projects thoroughly. Plan in advance, and perhaps as a group, to have what you need to document at least your midterms and finals. Photos, video, drawings, schematics, and notes are all valuable forms of documentation. Explain the project at the beginning of your documentation, so that people who come to the site from outside this class will understand the overview before they get the explanation. Don't overload your notes with code. If you've made a big improvement on an existing piece of code, post your new code, and link to the code you based it on (just as you would in citing a pervious author in a paper). If you only changed one part of an existing program, post only the part you changed, and link to the original. Make sure any code you post is well-commented, so you and others can understand what it does. Always cite the sources of your code, the places you learned techniques from, and the inspirations of your ideas. This is the equivalent to citing your sources in a written paper, and copying code or techniques without attribution is plagiarism. few ideas come out of the blue, and your readers can learn a lot from the sources you learned from or were inspired by. Work on this as you go, don't put it off until the end. Your fellow classmates will find your notes as useful too. Pictures help a lot. A few good recent sample journals:

The construction techniques are aimed primarily at wearables and soft circuit projects, but they'reuseful for a number of other projects as well. A longer list of books for inspiration and reference is available online at Tom's books link. Parts & SuppliesPartsA list of parts needed for the first few weeks follows. You will end up spending money on materials in this class. It can be done reasonably inexpensively, by scavenging parts, reusing parts, and so forth, but more ambitious projects inevitably make demands on your budget. Parts needed for Intro Physical Computing The NYU Computer Store carries kits to make your life easier. In it you will find enough parts to complete the basic instructions in each lab. They also carry a basic toolkit, with the minimum amount of tools you might need for the same (those tools can be handy around the house too). If you have none of your own parts or tools, purchase the basic parts kit and basic tool kit, at least. Here's what's in the kits.  physical computing parts kit
Here's what's in the kit:  5V voltage regulator  3.3V voltage regulator  LEDs  solderless breadboard  resistors  potentiometer  trimmer potentiometers  momentary switches  toggle switches  photocell  thermistor  ceramic capacitors  electrolytic capacitors  1N4001 diodes  zener diodes  transistors  DC power jack  AA battery holder  9V battery snap  servomotor  DC motor  gearbox kit  H-bridge  reed relay  screw terminals  DC Power Supply
In addition to the basic kits, they also carry a supplemental toolkit, some more interesting sensors and actuators that you might find helpful to do the more creative steps at the end of each lab. When you go to the bookstore to buy your kit, bring your student ID. The intro kits will be reserved for ITP students for the first few weeks of the semester. |
