Advances in HCI: Mixed Reality for Immersive Experiences

These flashcards cover key vocabulary related to mixed reality and immersive experiences, important for understanding the lecture content.

Mixed Reality (MR)

A class of immersive systems that combine virtual and physical worlds.

Augmented Reality (AR)

A technology that overlays digital content on the real world.

Virtual Reality (VR)

A fully immersive digital environment where users can interact with a computer-generated space.

Marker-based Augmented Reality

A technique that uses physical markers to trigger digital overlays in the real world.

Marker-less Augmented Reality

A method that does not rely on markers but uses known features or mapped spaces for augmentation.

Visual SLAM

A technique that builds a map of an unknown environment while simultaneously tracking the camera's position using visual data.

Spatial Mapping

The process of a mixed reality device mapping the real space to create an understanding of it.

Interaction Models

Different ways users can interact with virtual objects in a mixed reality environment, including voice, gaze, and direct manipulation.

Tracking Systems

Mechanisms that keep track of the position and orientation of markers or features within the environment.

Registration Error/Drift

The inaccuracies in positioning virtual objects due to localization and orientation mismatches during tracking.
