- AI-Generated Content(also: AIGC)
- An umbrella term for text, images, audio, video, and other media produced by generative AI systems — especially large language models and diffusion-based text-to-image or text-to-video models — in response to user prompts. AIGC is widely used in creative tooling (backdrop…
- ARKit(also: Apple ARKit)
- ARKit is Apple's augmented reality development framework for iOS that enables developers to create AR experiences for iPhone and iPad. It uses the device's camera, motion sensors, and processor to detect surfaces, track movement, and place virtual 3D objects in the real world.…
- Adaptive Environment(also: Adaptive System, Responsive Environment)
- A physical or digital space that automatically adjusts its properties and behaviours in response to the people within it. Adaptive environments use sensors, machine learning, and actuators to modify lighting, sound, temperature, display content, or interaction modes based on…
- Advanced Driver Assistance Systems(also: ADAS)
- A family of in-vehicle technologies that partially automate driving tasks — adaptive cruise control, lane-keeping, automatic emergency braking, parking assistance, blind-spot monitoring — while a human driver retains overall control. ADAS are relevant to accessibility as steps…
- Affective Haptics(also: Emotional Haptics)
- A subfield of haptic interaction design concerned with using tactile and kinaesthetic feedback — vibration, pressure, temperature, squeezing, stroking, heartbeat-like pulsation — to communicate, evoke, or regulate emotion. Affective haptics draws on research showing that touch…
- Always-On Computing(also: Always-available computing, Continuous computing)
- A model of interaction in which computing devices — particularly wearables such as smartwatches, AR glasses, and fitness trackers — remain continuously active and accessible throughout the day rather than being engaged only for discrete tasks. Always-on computing shifts design…
- Ambient Intelligence(also: AmI)
- An environment enriched with networked, sensor-equipped devices that are sensitive and responsive to the presence and needs of people within it. Ambient intelligence systems anticipate user requirements by learning preferences and behaviours over time, and adapt their responses…
- Automated Employment Decision System(also: AEDS, AEDT, Automated Employment Decision Tool)
- A software system that screens, evaluates, categorises, recommends, or otherwise makes or facilitates hiring or employment decisions about job candidates or workers. AEDSs span résumé sorters, personality tests, gamified cognitive assessments, situational-judgement tests,…
- Autonomous Ferry(also: Self-Driving Ferry, Autonomous Passenger Ferry)
- A waterborne passenger vessel that navigates, docks, and avoids obstacles without a human pilot, typically using a sensor suite (cameras, radar, LiDAR, ultrasonic, IMU, GNSS) and a shore-based supervisory operator. Autonomous ferries are being trialled as sustainable…
- Autonomous Vehicle(also: AV, Self-Driving Car, Automated Driving System)
- A vehicle equipped with technology that enables it to navigate and operate without human input, ranging from partial automation features like adaptive cruise control to fully autonomous systems that handle all driving tasks. Autonomous vehicles represent a potentially…
