# Assistive Technology
**Domain:** Accessibility / Human-Machine Symbiosis
**Doc Type:** Canonical Technology Node
**Maturity:** Developed
## Definition
**Assistive technology** comprises devices and systems that support a person's communication, mobility, perception, cognition or independent action.
## Evolutionary Nexus
Stephen Hawking's public life made machine-mediated communication visible, while [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] frames technology more broadly as cognitive and metabolic exteriorization.
## Rights Context
Assistive systems can become part of effective embodiment. Users therefore need repair, interoperability, privacy, update control and protection against service termination. Dependency increases the provider's duty; it does not reduce the user's standing.
