KK1-4, KK14: Digital Systems & Types of Accessibility Aids

Question 1

What are digital systems?

Answer 1

Either a single device, or a collection of devices on a network, digital systems transform data into information, providing an output that meets the needs of the user.

Question 2

What are examples of digital systems?

Answer 2

Examples of digital systems include:
- Smartphones
- Smart fridges
- Wearable technology (e.g. smartwatches)
- Desktop and laptop devices
- Drones
- Nanosatellites

Question 3

What is an emerging technology?

Answer 3

Emerging technologies are recent technologies that are perceived of being capable of making change within society.

Question 4

Define ‘Robot’ and name the 4 components.

Answer 4

A robot is a device that can complete a specific task wit autonomy. A robot’s 4 components are:
1. A Power Source - Provides energy for robot to function
2. Actuators - Used to control and move the robot
3. Sensors - To collect data from their environment
4. Software - Provides instructions to the robot

Question 5

Define “Assistive Technologies” and name a few examples.

Answer 5

Assistive technologies are technologies that allow an individual or organization to complete a task they would not be able to complete without human intervention, or a technology that makes day-to-day activities easier.
Examples include:
- Accessible Aids
- Cognitive Aids
- Electric Wheelchairs

Question 6

Explain what a ‘GPS’ is.

Answer 6

A Global Positioning System, or GPS, makes use of a network of satellites that provide location and time data to any connected device. They are operated and controlled by the US Government, and have a location range between 1 and 10 metres.

Question 7

What is an assistive technology?

Answer 7

An assistive technology
is any technology that allows an individual or organisation to complete
a task that they would not normally be able to complete, or that makes it easier or safer to complete day-to-day activities.

Question 8

What are the first 3 types of assistive technologies?

Answer 8

First 3 types of assistive technologies:
- Accessibility aids: Makes everyday tasks accessible to everyone, especially the disabled (e.g. text-to-speech software).
- Cognitive aids: Intended for people with a physical, cognitive or emotional impairment (e.g. ‘brain training’ games to help a person’s memory).
- Personal emergency response systems: Can send an alert to a nominated phone number, or an alarm when triggered (e.g. a smoker detector in a house).

Question 9

What are the last 2 types of assistive technologies?

Answer 9

Last 2 types of assistive technologies:
- Home automation: Home automation systems employ sensors and actuators to complete day-to-day tasks in the
home (e.g. controlling energy systems in the house).
- Mobility aids: To aid people with disabilities (e.g. electric wheelchair)
