Activity Tracker(also: Fitness Tracker, Step Counter, Fitness Band)

An activity tracker is a wearable device or smartphone application that monitors and records physical activity data such as steps taken, distance traveled, calories burned, heart rate, and sleep patterns. In accessibility contexts, activity trackers raise important design…

AgeTech(also: Age tech, Technology for older adults)

A broad category of technology designed to support older adults in aging well, living independently, and managing age-related health conditions. AgeTech spans smart-home monitoring, voice assistants, medication reminders, fall-detection wearables, social companion robots,…

Center of Pressure(also: COP, Centre of Pressure)

The point on a surface where the total sum of pressure forces acts, used as a key measure in balance and postural stability assessment. In standing balance evaluation, COP is measured using force plates or pressure-sensing devices like the Nintendo Wii Balance Board. COP path,…

Collaborative Tracking(also: Collaborative Self-Tracking)

Collaborative tracking is the practice of multiple people - typically a person with a health condition and their caregivers or allies - contributing to and reviewing shared health or behaviour data. It extends personal informatics from individual self-knowledge into…

Cueing(also: External Cueing, Sensory Cueing)

In rehabilitation, cueing is the delivery of external sensory stimuli - visual, auditory, or somatosensory - that guide or trigger a motor action. Cueing is used most prominently in Parkinson's disease, where basal ganglia dysfunction impairs internally generated movement…

Dialogue of Care(also: Care Dialogue, Care Communication)

The ongoing exchange of information, observations, and concerns between a person receiving care and their carers — whether professional, familial, or informal. In assistive technology and telecare contexts, the dialogue of care refers to the shared understanding that develops…

Digital Biomarker(also: Digital Health Marker, Passive Biomarker)

A quantifiable physiological or behavioral measure collected through digital devices (such as smartphones, wearables, or sensors) that can serve as an indicator of health status, disease progression, or treatment response. In accessibility contexts, digital biomarkers derived…

Digital Health(also: eHealth, Digital Health Intervention)

The use of digital technologies — including mobile apps, social media platforms, wearables, telemedicine, and AI tools — to deliver, coordinate, or support healthcare services and health information. Digital health spans clinical, public health, and community applications, and…

Digital Well-Being(also: Digital wellbeing, Digital wellness)

A field of research, design, and consumer technology focused on supporting healthy, intentional relationships between people and their devices. Digital well-being spans screen-time tracking, attention management, notification control, distraction blockers, intentional-use…

EndeavorRx(also: Endeavor Rx, EndeavorRx DTx)

The first FDA-cleared prescription digital therapeutic for children with ADHD, cleared in June 2020. EndeavorRx is a mobile video game designed to improve attention function in children aged 8-12 with ADHD by targeting neural systems associated with attention through sensory…

Exergames(also: Exertion games, Active video games, AVGs)

Video games designed to require physical exertion — whole-body movement, resistance, or sustained aerobic activity — as the primary input modality. Exergames span consumer titles (e.g., Wii Fit, Ring Fit Adventure) and clinical applications for rehabilitation, balance training,…

Fall Prevention(also: Fall Risk Reduction, Falls Prevention)

Strategies, interventions, and technologies designed to reduce the risk of falls, particularly among older adults and people with mobility or balance impairments. Falls are a leading cause of injury, hospitalization, and loss of independence in aging populations. Fall prevention…

Gait Training(also: Gait Rehabilitation)

Gait training is therapeutic practice aimed at improving walking function - velocity, stride length, symmetry, stability, and cadence - in people with neurological or musculoskeletal impairments. It is central to rehabilitation after stroke, spinal cord injury, and lower-limb…

Health Data Visualization(also: Health Data Display, Patient Data Visualization)

The presentation of personal health information — such as blood glucose levels, blood pressure readings, activity data, or medication schedules — in visual formats including graphs, charts, trend lines, and indicators designed to help patients understand and manage their health…

Persuasive Technology(also: Captology, Behavior Change Technology)

Interactive computing systems designed to change users' attitudes or behaviors through persuasion rather than coercion. Common persuasive techniques include goal-setting, self-monitoring, rewards, reminders, and social comparison. While persuasive technology has shown success in…

Physiological Sensing(also: Biosensing)

Measuring bodily signals - such as heart rate, galvanic skin response, skin temperature, respiration, or muscle activity - to infer aspects of a user's physical or affective state. Physiological sensing is widely used in accessibility, affective computing, and digital health to…

Serious Games for Health(also: SG4H, Health Games, Therapeutic Games)

Serious Games for Health (SG4H) are video games designed primarily for clinical, rehabilitative, or health-education outcomes rather than entertainment, while still using game mechanics, narrative, and reward systems to motivate engagement. They are used in physical therapy,…

Stroke Recovery(also: Stroke Rehabilitation, Post-Stroke Rehabilitation)

The process of regaining physical, cognitive, and communicative abilities lost or impaired following a stroke (cerebrovascular accident). Stroke is the leading cause of adult disability, with survivors often experiencing hemiparesis (weakness on one side of the body), loss of…
