Wearable computing is the design and use of computing devices worn on or close to the body, integrating sensing, processing and display into garments, accessories and head-mounted units. These devices provide continuous, context-aware interaction and data capture without occupying the hands, enabling hands-free assistance, health monitoring and immersive experiences. It is a foundational layer of spatial and ambient computing.
Overview
- Wearables bring computing into close, persistent contact with the user, shifting interaction from sessions to continuous awareness.
- They emphasise hands-free, glanceable and context-sensitive interfaces.
- On-body sensors capture motion, physiology and environment as input streams.
- Wearable computing converges with Internet of Things connectivity and Extended Reality displays.
Key aspects
- Body-worn form factors constrain power, heat, weight and ergonomics.
- Sensor fusion combines accelerometry, biometrics and location into context.
- Low-power processing and efficient connectivity sustain all-day operation.
- Privacy and continuous data capture raise distinctive governance concerns.
Applications
- Fitness and health monitoring through smartwatches and bands.
- Hands-free assistance and remote support via smart glasses.
- Immersive augmented and mixed reality through head-mounted displays.
- Industrial and field work where hands-free instructions improve safety.
