## Summary  
A smartphone-based virtual reality headset is a head-mounted device that uses a smartphone as its primary display and processing unit. It provides virtual reality experiences by leveraging the smartphone's screen, sensors, and computing power. Examples include Google Cardboard and Samsung Gear VR.

## Key Facts  
- **Subclass of**: Virtual reality headset  
- **Uses**: Smartphone (as display device and processor) and lenses  
- **Different from**: Standalone virtual reality headsets (which have built-in displays and processors)  
- **Examples**: Google Cardboard, Durovis Dive, Samsung Gear VR  
- **Aliases**: Smartphone VR headset, mobile VR headset, phone-based VR goggles  
- **Commons Category**: [Smartphone-based virtual reality headsets](https://commons.wikimedia.org/wiki/Category:Smartphone-based_virtual_reality_headsets)  
- **Wikidata Description**: "Virtual reality headset that utilizes a smartphone as its main processing unit and display"  

## FAQs  
### Q: How does a smartphone-based VR headset work?  
A: The headset holds a smartphone in front of lenses that split the screen into two images (one for each eye), creating a stereoscopic 3D effect. The phone's sensors track head movements to adjust the view in real time.  

### Q: What are the advantages of smartphone-based VR headsets?  
A: They are cost-effective since they reuse smartphones instead of requiring dedicated hardware. They are also lightweight and portable compared to standalone VR systems.  

### Q: Can any smartphone be used with these headsets?  
A: No, compatibility depends on the headset model and the smartphone's screen size, resolution, and sensor capabilities. Some headsets, like Gear VR, are designed for specific phone models.  

## Why It Matters  
Smartphone-based VR headsets democratized access to virtual reality by eliminating the need for expensive, specialized hardware. They made VR more affordable and portable, enabling widespread adoption for education, entertainment, and casual use. While less powerful than standalone or PC-tethered VR systems, they introduced millions to immersive experiences and paved the way for advancements in mobile VR technology. Their simplicity and low cost also spurred innovation in VR content and applications.  

## Notable For  
- **Affordability**: Leveraging existing smartphones reduces costs significantly.  
- **Portability**: Lightweight and easy to transport compared to bulkier VR systems.  
- **Early Adoption**: Google Cardboard popularized VR for mainstream audiences.  
- **Modularity**: Compatible with a range of smartphones (depending on model).  

## Body  
### Design and Functionality  
- Uses a smartphone's display as the primary screen.  
- Lenses split the screen into two images for stereoscopic 3D.  
- Relies on the phone's gyroscope and accelerometer for head tracking.  

### Examples  
- **Google Cardboard**: A low-cost, cardboard-based headset designed by Google.  
- **Samsung Gear VR**: A more advanced model with additional sensors and compatibility with Samsung phones.  
- **Durovis Dive**: An early smartphone-based VR headset model.  

### Limitations  
- Limited processing power compared to standalone VR headsets.  
- Dependent on smartphone battery life and performance.  
- Less precise tracking than dedicated VR systems.
