- Closed-Loop Adaptation(also: Closed-Loop System, Adaptive Loop)
- A system design approach where real-time feedback from sensors or user behavior is continuously monitored and used to automatically adjust the system's response. In accessibility technology, closed-loop adaptation enables interfaces to respond dynamically to users' physiological…
- Loosely Coupled Interaction(also: Loosely Coupled Dual Interaction)
- An interaction architecture in which two or more user interfaces share the same underlying content and data but operate independently through separate, non-overlapping input and output modalities. In a loosely coupled system, each interface is purpose-designed for its target…
- Role-Based Access Control(also: RBAC)
- An authorisation model in which system permissions are attached to roles (e.g., user, administrator, clinician, caregiver) and users are granted one or more roles rather than permissions directly. Widely used in healthcare, enterprise software, and increasingly in…
- Threat Modeling(also: Security Threat Modeling, STRIDE)
- A structured engineering practice for identifying, categorising, and mitigating security and privacy threats in a system before they are exploited. The widely used STRIDE framework (Microsoft) covers six classes — Spoofing, Tampering, Repudiation, Information disclosure, Denial…
