Workshop
Interaction
This physical computing workshop aims to experiment with simple input and output mechanisms that utilise electronics.
This may be unusual and uncharted territory for a designer, but as we extend traditional design products into digital and virtual space, we also explore how design can be applied to physical applications that a user can interact with to create physical and tangible experiences.
Through prepared materials and electronic components, you will design a simple physical interaction that demonstrates how a physical input triggers a digital output or vice versa.

Interaction
Design can function at multiple levels and in different ways. Design professor Richard Buchanan captured his thinking into these ‘four orders of design’ illustrating how design as a discipline has moved from the traditional concept of the visual or tangible artefact through to orchestrating interactions and experiences, and to transforming systems.
Four Orders of Design. Symbols, Objects, Actions, Systems.

Four Orders of Design
2D Graphic Design, deals with the nature, shape, and meaning of symbols and consists of four distinct but related activities: typography, illustration, photography, and print. 2
Systems and environments. Environmental design is concerned with “[t]he idea or thought that organizes a system or environment” Therefore, in the fourth order, the focus is on human systems, “the integration of information, physical artifacts, and interactions in environments of living, working, playing, and learning.” 2
4D Interaction. In interaction design, the locus of design is action. Here, the focus is on designing experiences rather than physical objects. 2
3D Industrial Design, industrial design is concerned with tangible, physical artifacts — with things. 2

Interactions and Physical Computing
- What is Physical Computing
- Key components of Physical Computing
- Digital and analog worlds
- Why?
- What is possible?
Physical Computing refers to the design and implementation of interactive systems that bridge the digital and physical worlds.
It involves using hardware and software to create systems that can sense and respond to the physical environment.
These systems not only need to be engineered but more importantly for us, designed.
Physical Computing
-
Sensors: Devices that can detect physical inputs from the environment, such as light, temperature, motion, or sound.
-
Actuators: Components that can take digital information and convert it into physical actions, such as motors, LEDs, or speakers.
- Microcontrollers: Small, programmable computers that serve as the brain of a physical computing system. They read input from sensors, process data, and control actuators.
Physical Computing
Key components include
-
Programming: Writing code to define the behavior of the system, including how it responds to input from sensors and how it controls actuators.
- Designing Interactions: How do we or how can we interact with the physical world through interfaces that connect the digital with the physical.

Why?
Design as a Force for Good: Lim Si Peng and Ong Kian Peng
DesignSingapore (Dsg) Scholars Lim Si Ping and Ong Kian Peng harbour a profound passion for design and the transformative impact of technology.
Interactions and Physical Computing
Why?
My role as a designer is not just to create visually stunning pieces but also to engage, challenge, and connect with people on a deeper level.
Don’t blindly chase technology. Use them meaningfully. Find poetic uses for technology. That’s our role as designers.

What's possible?
Can't Help Myself - Placed behind clear acrylic walls, their robot has one specific duty, to contain a viscous, deep-red liquid within a predetermined area. When the sensors detect that the fluid has strayed too far, the arm frenetically shovels it back into place, leaving smudges on the ground and splashes on the surrounding walls.
Wifi Tapestry - dynamic wall hanging that visualises the wireless activity of a space. The tapestry visualises the ever changing "landscape" of radio frequencies around us.
Take some time to reflect on
these references
- Which did you like, which did you prefer less?
- How have these examples broadened your perspective on what physical computing is?
- What ideas sprouted out from what you have seen?
Yo–Yo Machines are playful communication devices that you can make yourself. They’re designed to fill a gap by letting people send one another nonverbal, expressive signals like lights, sounds or simple movements.

- Arduino demonstration
- Coding Arduino, the Arduino IDE
Arduino is an open-source electronics platform that consists of both hardware and software components.
It provides a simple and accessible way for individuals, including hobbyists, artists, and students, to create interactive electronic projects.
The Arduino platform includes an easy-to-use integrated development environment (IDE) for programming, as well as a variety of microcontroller boards.

In this exercise, you and your group will receive a small electronics prototyping kit, which includes an Arduino board and a Grove Shield (explanations of both will be provided in the following slides).
With this kit, you can experiment with basic inputs and outputs—such as LED lights, buttons, or knobs. But why should you, as a designer, understand how this works?

Configures the specified pin to behave either as an input or output
Control a digital pin by writing a HIGH or a LOW value to it
Reads the value from a specified digital pin, either HIGH or LOW
Writes an analog value to a pin, a value here can be between 0 and 255
Reads the value from an analog pin which in most cases is able to return a values between 0 and 1023
Pauses the program for the amount of time (in milliseconds)
