CS294-84 / ME290U: Interactive Device Design

Fall 2013, UC Berkeley. CCN: 27010 (3 units)

This course teaches concepts and skills required to design, prototype, and fabricate interactive devices -- that is, physical objects that intelligently respond to user input and enable new types of interactions. The first half of the semester will be dedicated to a survey of relevant techniques in 3D modeling and fabrication; electronics and circuit board design; sensing and actuation for interaction; embedded software development, wired and wireless communication with mobile devices, computers, and networks; and user interface programming. In the second half of the semester, students will propose and carry out a significant design project of their own choice in groups. We encourage students to work on projects in health technologies (a CITRIS focus area); PhD students can also explore projects related to their area of research after consultation with us.

Class sessions will alternate between concepts and experiential learning. All classes will be held in the CITRIS Invention Lab, 141 Sutardja Dai Hall.

Enrollment

Because of the hands-on nature of this course, we have a strict capacity limit of 30 students. All students are initially placed on the wait list. In order to be considered for the class you must:

  • Be on the waitlist for either CS294-84 (Hartmann) or ME290U (Wright)
  • Come to the first class meeting and sign in
  • Fill out our entry survey by Wednesday 9/4 11:59pm

Prerequisites

  • Programming experience required: This is a computer science course. You will program embedded systems for this course. You should be able to pick up a new language and API (with some help from us). Knowing the equivalent of the CS61A-C series at Berkeley should be sufficient.
  • User Interface Design experience very useful: Your projects will have both software and hardware user interfaces. Some background in user interface design, e.g., INFO290 Tangible Interaction or CS160 User Interface Design is valuable.
  • 3D modeling skills very useful, but not required: You will model and fabricate parts on our FDM machine. If you want to get a head start, learn how to use SolidWorks, but we'll also have a tutorial.
  • Some electronics experience useful, but not required: You will build basic sensing and actuation circuits. The threshold for doing this has decreased rapidly in recent years, but you will be soldering your own electronics. If you have taken the equivalent of EE40 or have built projects Arduino boards before, you'll be fine.

If you have no programming background, you should not take this course. If you do not have experience in at least one of (UI design, 3D modeling, electronics) you should not take this course. You must be comfortable with learning a sizable set of new tools and processes, quickly.
