Given the recent (and not so recent) comments on the Touch vs Vive room-scale argument I just wanted to get this clear. It seems a lot of people are misunderstanding, and a lot of people are blindly supporting one over the other. Please correct me if I am wrong.
1. Lighthouse & Constellation tracking systems both require a direct line of sight from the Lighthouse station (Vive) / Camera (Rift), to the Controller Sensor (Vive) / LED (Rift).
2. In the above respect they are identical. And the difference between lazer tracking and optical tracking is not significant. The only major difference is that the Lighthouses only require power while the cameras require a USB connection to the PC (may cause issues due to USB cable lengths).
3. The only significant difference between the two systems is the layout of the Sensors (Vive) and LED's (Touch) on the controllers.
4. The Vive has placed it's sensors on the end of a long wand to avoid occlusion by the hands and body, facilitating better tracking for room-scale. Unfortunately this means they will feel less like hands and more like sticks and will physically collide when brought close together.
5. The Touch has placed the LED's close to the hand allowing the hands to be used closer together for 2 hand interactions. Unfortuantely this means that they are more likely to be occluded when used with only 2 cameras in a room-scale setup.
6. Importantly Touch could replicate the room-scale tracking of the Vive by copying the design of the Vive wands and placing their LED's on the end of a wand. and Vive could replicate the fine interaction of Touch, by copying the design of the Touch controllers and replacing the LEDs with lighthouse sensors.
7. and TLDR Both systems are basically equal, the only significant difference is the shape of the controllers. Each could replicate the others shape to achieve the same effect.
One final consideration, additional cameras will help with Touch occlusion issues. However placing cameras may be complicated by USB cable lengths. The only way to make finer interaction possible with the Vive is to make smaller controllers.
Edit - One more consideration is the finger tracking that the touch controllers apparently enable. Though the specifics of how this is achieved are currently unconfirmed.
