Syllabus Spring 2015

Wednesday 9:00 – 11:30AM

Tom’s calendar of office hours

The World Wide Web no longer stops at the edge of your screen. When it comes to products, if it powers up, it talks to another device. There’s an increasing number of appliances coming on the market that feature web interfaces, but do they work well? This class take a hands-on critical look at the emerging market for connected devices, and will present an overview of methods for connecting the physical world to web-based applications. We don’t interact with connected appliances in the same way as we do when they’re not connected. It’s not enough just to bolt a touchscreen on an appliance and call it networked. In this course we’ll consider what the emerging interaction patterns are, if any, and we’ll develop some of our own as needed.

This class can be seen as a narrower and more interaction design-based complement to Understanding Networks. The latter class provides a broader overview of the dynamics of data networks, while this class focuses specifically on the challenges of connecting embedded devices to web-based services. Neither class is a prerequisite for the other, however.

The class will begin with a review of some existing connected devices on the market, in which we’ll critique them as products of interaction design. Then we’ll have several short exercises to introduce different tools, and a final hardware and software production project in which students develop a more fully realized networked device.

Prerequisites: Intro to Physical Computing, Comm Lab: Web, and Intro to Computational Media, or equivalent experience with the topics covered in those three classes.

General Structure:

We’ll start each class with a review of any homework assignments, readings etc. Come prepared to present when you have an assignment due, and come having done the reading and prepared to discuss and ask questions when a reading has been assigned.

Following the homework/reading review, we’ll discuss new material. This will cover both programming and design techniques as well as general topics related to the class. There will likely be one or two guest speakers, TBD.

Assignments:

There are several homework assignments that illustrate the technical topics. You should be prepared to show your project on any week in which an assignment is due.

Commenting on each others’ work: 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 and on their interaction with their intended user. Offer suggestions on what they do 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. Give them these notes at the end of class, or comment on their project page online. 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.

Blog assignments are assigned throughout the course, on a variety of topics. They should be finished a day in advance of the day we will discuss them; in other words, if we’re discussing them Wednesday, finish them by Tuesday. For reviews, use the class blog, so we are all in the same place. For group projects or individual projects, feel free to blog externally and link to the project page.

At the very least, you should have a page for each assignment. For the readings, if no one else has blogged it, start a new post. If there’s already a post, you can either comment on existing posts or add your own.

Read and comment on each other’s writings as well.

Class 7

Mar. 11

  • Discuss non-technical readings
  • Final Project Concept Development

For the first half of this class, we’ll talk about the various topical readings we’ve been through this semester and have a discussion about the big picture: where is it all going and how does it intersect with the life we want to live?

In the second half of this class, we’ll brainstorm many different concepts, then break into groups to examine how useful they are, and how feasible. Each person should come in with three different ideas for a possible connected device system, in three sentences or less each. We’ll put them all on the board, compare them, sort them, and identify a subset of the most promising ones. Then we’ll decide on groups based on everyone’s stated interest in the concepts.

Grading

  • Participation & Attendance: 40%
  • Production Assignments: 30%
  • Documentation/Blogging: 30%

Participation & Attendance

Showing 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 contact me in advance. If you have an emergency, please let me know as soon as you can. Please turn in assignments on time as well.

Laptops/Tablets

Laptop and tablet 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, close your lid, and pay attention.

Mobile Phones

Please 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.

Production Assignments

For production assignments, you’ll be expected to present your project in class on the day that it’s due. When you have an assignment or presentation due, show up to class on time. You may be called on first.

Working in Groups

If you’re working in a group, all group members should be present, and should participate equally in the presentation. Each member should be knowledgeable about all aspects of the work enough to explain that aspect to an audience, whether you did that particular part of the project or not.

For the group assignments, each group should assign a member to take responsibility for one or more aspect of the project, e.g. software/firmware, user interface, interaction, hardware, fabrication, documentation. You may want to break it down further than that, but those are good starting areas.

Being responsible for an area doesn’t mean you are doing all the work in that area. It means you’re keeping track of that area’s progress and working with your partners to make sure it’s on track. When a decision needs to be made in that area, you’ll decide and communicate it to the others, and you’ll all act on it accordingly. If things are lagging in that area, you should work with your group members to address the problem, and in the absence of other ideas, they’ll look to you for a decision on how to proceed. It also means that in class presentations, you’ll report on that area. Decide who’s responsible for what early on, and post it to your group’s project page, so the whole class knows.

Documentation

The class blog is here to record your progress and to keep a record for future classes. For review assignments, use the class blog so we have them in one place, and respond to each others’ posts as well. At the very least, make sure you’ve read your classmates’ posts before a reading assignment is due, so you can comment knowledgeably or ask questions of each other in class.

For production assignments, you can either use the class blog or your individual sites. Regardless of which you do, give each project a summary page on the class blog, at least. This makes it possible for future classes to search past projects. If you’re keeping your documentation on an external site, make sure links to that external site are included and updated on your project page.
