Physical Computing: Sensing

Lecturer: Nathan Gates

This is the central repository for all information relating to the physical computing workshop.
All resources for the course such as readings, examples, references documents and updates will be here..
The sensing workshop is 4 weeks long and will culminate in a mini-project.

Im still in the process of finalising the Mini Project and research assignment brief, they will be put up shortly

Important Lab Information

We cover a lot of content in this module and expect a unique and considered application of this content to the final Mini-Project. .
Students are expected to attend all lectures as well as work independently, and consistently throughout this period (and the rest of the course) to deliver on the course projects.

Please look over this, it contains information pertinent to the module. As this the main communication channel for the course I will assume you have read it.

Week One: Introduction to Physical Computing

The first week will be a introduction to interactivity and electronics to get you familiar with the basic concepts informing physical computing. Please complete the reading before the start of the week.

Week Three: Research Presentations, Serial Communication Continued

Students are to present their research break homework to the class for feedback and critique, and discuss their way forward regarding the project.
We will continue looking at more robust methods of Serial Communication that you will incorporate into your final projects

Readings

Lev Manovich: "Media After Software" (2012)

Lesson Five

Students presentation to class for feedback and critique. After the presentation we will look at more advanced methods of Serial Communication

Lesson Outcomes

  • Student will receive critique and feedback from class
  • How to implement more robust methods of Serial Communication using handshakes and assembling your own 'data packets'

Lesson Six

This class will be used to recap on important concepts from previous lectures.
One-on-one consultations should be organized in advance due to class size

Lesson Outcomes

  • Recap of previous classes and concepts
  • Supervised lab time to work on / discuss projects.
