Level of Detail(also: LOD)

A technique in computer graphics and information design where the amount of detail presented varies based on context, typically distance or user interaction. In 3-D environments, objects farther from the viewer are rendered with less geometric detail to improve performance. In…

List-Based Interface(also: List View, Linear Interface)

An interface layout that presents information as a sequential list rather than in a grid, table, or spatial layout. In accessibility contexts, list-based interfaces are generally more screen reader-friendly than grid layouts because they follow a natural linear reading order,…

Locomotion(also: VR Locomotion)

Methods by which users navigate and move through virtual environments in VR. Common locomotion techniques include free-roam (physical walking that maps to virtual movement), joystick-based continuous movement, teleportation (pointing to a destination and instantly moving there),…

Locomotion Technique(also: VR Locomotion, Virtual Travel Technique)

A locomotion technique is a method for navigating or moving through a virtual environment in virtual reality (VR). Because physical space is limited and many users are seated, locomotion techniques simulate travel without requiring real-world walking. Common approaches include…

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…
