Acoustic Activity Recognition(also: Sound Activity Recognition, Audio Activity Recognition, Environmental Sound Recognition)

The use of microphones and machine learning to automatically identify and classify sounds occurring in an environment, such as doorbells, alarms, appliances, speech, and other everyday acoustic events. Acoustic activity recognition is particularly relevant to accessibility for…

Activity Monitoring(also: Activity Recognition, Activity Tracking)

The use of sensors, algorithms, and computational models to automatically detect and track a person's actions and behaviours within an environment. In assistive technology contexts, activity monitoring enables smart home systems and cognitive orthoses to understand what a person…

Ageing in Place(also: Aging in Place)

The ability of older adults to live independently and safely in their own home and community for as long as possible, regardless of age, income, or ability level. Ageing in place is increasingly promoted as an alternative to institutional care, supported by technologies such as…

A cloud-based voice assistant developed by Amazon, available on Echo smart speakers, Echo Show smart displays, and third-party devices. Users interact with Alexa through wake-word-activated voice commands to perform tasks such as setting reminders, playing music, controlling…

Ambient Display(also: Ambient Interface, Peripheral Display)

A display or interface that communicates information through subtle environmental changes — such as colour shifts, lighting changes, or gentle sounds — that can be perceived at the periphery of a user's attention without demanding direct focus. In accessibility contexts, ambient…

Ambient assisted living(also: AAL, Smart home assistive living)

Technology systems embedded in the home environment — including sensors, microphones, and smart devices — that monitor and support older adults or people with disabilities to live independently and safely. AAL aims to detect emergencies like falls, remind about medications, and…

Assisted Living Technology(also: Assistive Living Technology, Ambient Assisted Living, AAL)

Technology systems designed to help people with disabilities, chronic conditions, or age-related limitations live more independently in their homes or residential facilities. This includes smart home automation, health monitoring, fall detection, medication reminders, and…
