- Implicit Scoping(also: Prioritized Scoping)
- A voice navigation strategy that combines the efficiency of relaxed scoping with intelligent disambiguation. In implicit scoping, the system maintains awareness of the user's current focus area and prioritizes targets based on proximity and context. When a user issues a command,…
- RESOLV Icons(also: Representational Enumerated Semi-transparent Overlaid Labels for Voice)
- A visual disambiguation technique for voice interfaces where semi-transparent numbered labels are overlaid on screen elements that match an ambiguous voice command. When a user speaks a command that could refer to multiple targets, RESOLV icons appear next to each matching…
- Relaxed Scoping(also: Flexible Scoping)
- A voice navigation strategy that allows users to name any target on the screen directly without first navigating through a hierarchy. Relaxed scoping prioritizes efficiency by enabling single-command access to interface elements, but it increases the potential for target…
- Rigid Scoping
- A voice navigation strategy that requires users to explicitly navigate through a hierarchical structure before issuing commands to specific targets. In rigid scoping, the user must first select a container or menu level, then name items within that scope, preventing ambiguity by…
- Target Ambiguity(also: Command Ambiguity)
- A usability problem in voice and speech-based interfaces where a user's spoken command could refer to more than one element on the screen. For example, if multiple buttons share the same label in different parts of an application, saying that label creates ambiguity about which…
