b.1.4 input, output & specialist devices
How do we talk with computers? From keyboards and screens to advanced sensors and 3D printers, explore the devices that bridge the gap between human and computer.
A computer is useless if you can't tell it what to do or see the result. That’s where Input and Output (I/O) devices come in. It’s more than just mice and monitors. We explore how sensors let computers "feel" the world (like a thermostat knowing it’s cold) and how actuators let them move things (like a robotic arm). We also look at Assistive Technology - clever gadgets like eye-trackers and screen readers that open up the digital world to people with disabilities, ensuring everyone can connect.
Devices which we use to get data from the outside world into a computer system.
This page is mainly about output_devices
This section outlines the progressive curriculum mapping for Input, Output, and Specialist Devices. The framework traces a carefully structured pedagogical journey - from early years identification of basic peripherals, through to the advanced physical principles of transducers and haptics at the extension level. Crucially, it intertwines the theoretical understanding of hardware with vital social topics such as accessibility and assistive technology, whilst challenging older students to design robust Internet of Things architectures and automated control systems.
