# Terminologia XR:ssä

Nämä termit kattavat keskeiset käsitteet ja teknologiat Laajennetun Todellisuuden (XR) alueella ja sen eri immersiivisissä teknologioissa.\\

Laajennettu Todellisuus (XR) on kattotermi, joka käsittää erilaisia immersiivisiä teknologioita, mukaan lukien Virtuaalitodellisuus (VR), Lisätty Todellisuus (AR) ja Yhdistetty Todellisuus (MR). Tässä on sanasto keskeisistä XR:ään liittyvistä termeistä:

These terms encompass the key concepts and technologies within the realm of Extended Reality (XR) and its various immersive technologies.Extended Reality (XR) is an umbrella term that encompasses various immersive technologies, including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). Here's a glossary of key terms related to XR:

**Virtual Reality (VR)**

A technology that immerses users in a computer-generated, three-dimensional environment, typically through a headset or goggles. Users can interact with and navigate this virtual world.

**Augmented Reality (AR)**

AR overlays digital information or virtual objects onto the real world, often viewed through a smartphone or AR glasses. It enhances the user's perception of the physical environment.

**Mixed Reality (MR)**

MR blends aspects of both VR and AR, allowing virtual and real-world elements to coexist and interact in the same space. Users can interact with digital objects while still being aware of the physical environment.

**Immersive Technology**

A general term for technologies that create immersive experiences, including VR, AR, and MR.

**Haptic Feedback**

Technology that provides tactile sensations to the user, such as vibrations or force feedback, to enhance the sense of touch in virtual environments.

**Headset**

A wearable device, often in the form of goggles or glasses, used for viewing VR, AR, or MR content. It typically includes a display, sensors, and audio capabilities.

**3D Modeling**

The process of creating digital representations of objects or environments in three dimensions. 3D models are commonly used in XR applications.

**Teleportation**

In VR, this refers to a method of moving the user from one location or viewpoint to another within the virtual environment, often to prevent motion sickness.

**Field of View (FOV)**

The extent of the observable world or digital content a user can see through an XR device, typically measured in degrees.

**Motion Tracking**

Technology that captures and records the movement of a user's body or XR device. It's crucial for tracking user movements in virtual or augmented environments.

**Spatial Computing**

The integration of digital content into the physical world, allowing users to interact with virtual objects as if they were real.

**Hand Tracking**

A form of motion tracking that specifically tracks the movement and gestures of a user's hands, enabling natural interaction with XR content.

**Simulator Sickness**
