🚀 What Is Augmented Reality?
- AR overlays computer-generated content onto the real world in real time.
- Enhances reality instead of replacing it (unlike VR).
- Enabled through smartphones, tablets, smart glasses, and AR headsets.
🧰 Core Components of AR
| Component | Role |
|---|---|
| Input Devices | Cameras and sensors (GPS, accelerometer, gyroscope) |
| Processing Software | Analyzes surroundings and displays appropriate digital content |
| Display Devices | Smartphones, AR glasses, headsets, projectors |
🧩 Types of Augmented Reality
| Type | Description |
|---|---|
| Marker-Based AR | Uses images or codes (like QR) as triggers |
| Marker-less AR | Uses device sensors to map the environment without predefined markers |
| Projection-Based AR | Projects digital visuals onto physical surfaces |
| Superimposition AR | Replaces or enhances parts of the real view |
| Location-Based AR | Uses GPS to display content based on geographic location |
