1. **Safety Concerns**: When wearing a VR headset, users are often visually isolated from their surroundings. This can be dangerous when used outdoors, where there may be traffic, obstacles, or other hazards. Users might not be fully aware of their physical surroundings, increasing the risk of accidents or collisions. 2. **Portability and Power**: VR headsets are often tethered to a computer or gaming console, requiring a power source and limiting mobility. While some standalone VR headsets exist, they still have limited battery life, which can be problematic for extended outdoor use. 3. **Comfort and Weight**: VR headsets are designed for comfort during relatively short indoor sessions. Extended outdoor use can become uncomfortable due to the weight of the headset and the potential for heat buildup, especially on hot days. Straps and padding may not be suitable for outdoor wear over long durations. 4. **Calibration and Tracking**: VR systems often require calibration and tracking of the headset's position within a defined play area. When taken outdoors, this tracking may become inaccurate or unreliable, leading to a subpar VR experience. 5. **Privacy**: Wearing a VR headset outdoors can raise privacy concerns. Passersby might be able to see the content displayed on the screen, and users may not feel as secure as they would in the privacy of their homes. 6. **Limited Content for Outdoor Use**: Most VR content is designed for indoor scenarios and may not be optimized for outdoor environments. Outdoor-specific VR experiences are relatively limited, reducing the appeal of using VR outdoors.
