What This Document Is
This material provides a foundational exploration of Physical Computing, a field bridging the gap between the digital world of computers and our physical surroundings. It’s part of INFO 290 at UC Berkeley, a special topics course delving into innovative approaches to information technology. The content focuses on the theory and practical application of creating tangible user interfaces – ways for people to interact with computers using physical objects and movements. It examines how we can sense and respond to the physical world through computational means.
Why This Document Matters
This resource is ideal for students interested in interactive art, human-computer interaction, robotics, or anyone seeking to build projects that react to and influence the physical environment. It’s particularly valuable when you’re beginning to conceptualize projects involving sensors, actuators, and microcontrollers. Understanding these core concepts will empower you to move beyond traditional screen-based interfaces and create more intuitive and engaging experiences. It’s best utilized during the initial stages of project design and development, or as a reference during implementation.
