Hardware
Physical computing can be broken down into different parts: hardware, which includes the computers themselves and the sensors and actuators that gather and display data; and software, where all the decisions are made about what the computer actually does.
In this step Dr Steven Houben from Lancaster University gives us his introduction to physical computing and some examples of the hardware involved.
In the next step, he will follow up on more hardware commonly found in physical computing: the transducers.
Over to you:
As you listen to Steve’s presentation, think about a physical computing device that you have close at hand – for example, your watch or even a doorbell.What information are the input transducers, or sensors, relaying to the computer?
