There is no straightforward answer to the questions which is better - Dual Depth Sensor or Sony PS Eye Cameras configuration. The accuracy of tracking is almost the same. Pros and cons summary:
| Cameras | Pros | Cons |
|---|---|---|
| Dual Depth Sensors |

| Sony PS Eye (3 to 8 cameras) |

General Recommendations
- Dual Depth Sensor configuration is very practical, it is easier to use and able to track many kinds of motions. We can recommend it if:
- Your room is not very big (less than 20 x 20 feet = 6 x 6 meters)
- You do not need to track fast complex motions like energetic dancing, acrobatics, etc.
- You do not need to track 2 actors
- Sony PS Eye cameras is the most powerful option, but you have to invest more time in learning. We can recommend it if:
- 7 x 7 feet ( = 2 x 2 meters) capture area is not enough for your motions, and your room is bigger than 20 x 20 feet ( = 6 x 6 meters)
- You plan to track fast complex motions like energetic dancing, acrobatics, etc.
- You plan to track 2 actors
