Oculus 3-Sensor 360º and Roomscale Experimental Setup Quickstart Guide When you set up your Oculus Rift and Touch, we recommend putting your 2 sensors in front of where you'll be wearing your headset. However, you can choose to buy a 3rd sensor to try our experimental 3-sensor 360° tracking setup. By following the steps in this guide, you’ll be able to experience 360° tracking in a play area that you'll map out, which can be up to 8x8 feet (2.5x2.5 meters). Note: Using 3 sensors to support 360º tracking or roomscale mode is an experimental configuration. Some of the steps in this guide may not work with your computer or play area. Note that we recommend you have at least 7x5 feet (2x1.5 meters) available for standing and roomscale apps and games. By following these steps you should be able to get a good experience with your 3-sensor 360º / roomscale setup. If you’re having problems with setup, contact support.oculus.com ⚠ WARNING: When plugging in the sensor cables, ensure that they do not create a tripping hazard and that your play area remains clear. It is recommended that the sensor cables be routed outside of the play area. 1. Make sure you plug 2 sensors into USB 3.0 and 1 sensor into USB 2.0. This helps balance the tracking data transfer load across your USB connections. 2. Set up your sensors in a configuration similar to the diagram below. We don’t recommend exceeding the maximum dimensions shown. 3. When you plug in your 3rd sensor, make sure to go through the Reset Sensor Tracking step in Settings > Devices in the Oculus app. 4. In the Sensor Tracking step shown below, make sure you stand near the center of your play area, facing a direction in which you can see both the rear sensor and at least one front sensor at the edges of your peripheral vision (out of the corners of your eyes), and make sure all three sensors can see your Touch controller. Putting the Touch controller above your head when pulling the trigger is also a good idea, to make sure all of the sensors can see the controller. You should now be able to continue through the remaining setup steps as normal. Once completed, your experimental 3-sensor setup should be ready to enjoy 360° and roomscale experiences. Full Walkthrough Guide Step 1: Plug In Your First 2 Sensors ⚠ WARNING!: When plugging in the sensor cables, ensure that they do not create a tripping hazard and that your play area remains clear. It is recommended that the sensor cables be routed outside of the play area. For the first 2 sensors, you can still set them up as shown below in the Stand Up and Place Your Sensors step, with both sensors on your desk, facing straight towards where you plan to use the Rift and approximately ~3-6 feet (~1-2 meters) apart. Ideally, for a roomscale setup, you’ll want these sensors to be even further apart than that, though. We’d recommend you place them as close to the left and right edges of your desk as possible, about 8 inches (20 centimeters) from the front of your desk if possible, and no further back than your monitor. Image 1.1: Recommended 2-sensor configuration from new user setup guide. Also, make sure that you plug both of these first two sensors into the recommended USB 3.0 ports. Image 1.2: A USB 3.0 port, recommended for the first 2 sensors. Step 2: Plug In Your 3rd Sensor Sensor 3 should be positioned behind and to one side of your planned play area, ideally pointing directly at the center point between the 2 sensors. Try to make your layout match the diagram below, with the 3rd sensor placed at the same height as the first 2 sensors. The 3rd sensor can be on either the left or right side of the room. However, we strongly recommend you don’t put it directly behind the front 2 sensors. You also can place your 3rd sensor farther away, up to 13 feet (4 meters) away from your front 2 sensors. Be sure to route the 3rd sensor cable outside of your play area so as not to create a tripping hazard. Image 2.1: Recommended position for the 3rd sensor, not more than 13 feet (4 meters) from the closest front sensor, and pointing approximately at the center of your play area, between the first two sensors. Due to potential USB bandwidth issues in most computers with USB 3.0 ports, it’s important that the 3rd sensor is connected to a USB 2.0 port. Having 2 sensors connected to USB 3.0 and one to USB 2.0 is the recommended configuration at this time. Connecting more than 2 sensors to USB 3.0 ports will generally pull too much data through the system, leading to inconsistent performance and/or sensor tracking failures. Image 2.2: A USB 2.0 port, required for the 3rd sensor. Note: If you purchased your 3rd sensor from Oculus.com, it should have been bundled with a USB 2.0 extension cable. When connected via this cable, your sensor will automatically be put into USB 2.0 mode, so it’s safe to plug this cable into a USB 3.0 port. We recommend plugging into a USB 2.0 port if you have one available. If you wish to purchase additional extension cables, you can do so directly from Monoprice: Monoprice USB 2.0 Active 16ft Extender cable (Product #8751). We recommend that you do not plug in more than 2 sensors using USB 2.0, since it may cause bandwidth issues with your PC's USB controller. Step 3: Start Configuration with Oculus Setup If you’ve just purchased a Rift and your computer doesn’t have the Oculus software installed, download Oculus Setup from www.oculus.com/setup, and choose Rift + Touch, which will take you through setting up all of your Oculus devices, including your sensors. If you’ve already purchased a Rift and/or Touch controllers, and want to set up 3 sensors to support the experimental 360º tracking or roomscale modes, start by going to your Settings menu in the Oculus app on your computer. Click Devices on the left, click Configure Rift in the top right and then select Reset Sensor Tracking. Image 3.1: The “Reset Sensor Tracking” Menu item, to be used if you’ve already gone through full Oculus setup. Note: After plugging in a 3rd sensor, the Oculus software may prompt you that your sensor configuration has changed, and thus you need to go through setup again. You can just select Yes to go through the same process as manually selecting the Reset Sensor Tracking above. Continue through setup until you get to the USB Communication Test screen. You should see 3 sensors listed on the left, and they should all pass the test. Image 3.2: You should see 3 sensors listed in the USB Communication Test screen. Image 3.3: A successful USB test indicates that your sensors are connected properly and ready for placement and tracking setup. Troubleshooting: What if one of my sensors doesn’t show up, or I see an error during the USB test? Image 3.4: Potential USB Communication test errors Try the following: - Try clicking the Retry button to see if it was a one-off error. - Make sure one of your sensors is connected to a USB 2.0 port, and the other 2 are connected to USB 3.0 ports. - Try connecting one or more of your sensors to a different port. If you have clusters of USB ports that are located farther away on your computer, try those ports. Sometimes USB ports located close to each other are on the same internal USB hub, which can lead to bandwidth issues. - Try restarting your computer, and repeating the sensor setup steps above. - Look at your Windows device manager control panel, under the Oculus VR group and make sure all 3 “Rift sensors” are showing up there. If not, try unplugging/replugging your sensors and/or restarting your computer. - If you have a webcam connected to the same set of ports that your sensors are connected to, try moving the webcam to another port, or disconnect it entirely as a test. Image 3.5: Searching for Windows Device Manager control panel Image 3.6: Confirm there are 3 devices named “Rift Sensor” under the “Oculus VR Devices” category. Step 4: Configure Sensor Tracking The next step is to configure your sensor placement and Touch controllers. You should continue through the guided Oculus setup until you get to the Sensor Tracking screen: Image 4.1: Sensor Tracking setup screen Normally, with 2 front-facing sensors, you’ll want to face toward your monitor while setting up tracking. But with a 3-sensor setup, you’ll want to use a different strategy. You should hold your Touch controller at eye level as instructed, however instead of facing your monitor you should face in a direction perpendicular to an imaginary line between your 2 front sensors and your 3rd rear sensor. This will help make sure that all three sensors can see the Touch controller during this step. If you’re having trouble, try holding your Touch controller above or on top of your head while holding down the trigger. Again, make very sure that your 3rd sensor is off to either side, and pointing toward the center of your play area. You’ll now be asked to point your Touch controller forward, and move your arm until sensors appear correctly in the diagram, relative to your monitor position. You should see three sensors on the screen, which will move as you move your arm. Squeeze the trigger when the sensor positions on the screen match where they are in your room. Image 4.2: Rotating sensors to match the correct position in your room Note: Once you’ve fully the completed sensor setup, you should see all 3 of your sensors present in the final screen of the tracking setup. It should look something like the image below, depending on your particular play area. Image 4.3: Example of a successful 3-sensor setup screen Step 5: Setup Guardian System After you’ve finished setting up your sensors, we strongly recommend mapping out the boundaries of your play area with Guardian System. This process should be the same as in a 2- sensor setup. Image 5.1: Mapping out Guardian System boundaries Step 6: Set Your Position in VR Continue through setup until you reach the point where you’re asked to put on your headset and continue in VR. Image 6.1: Set your view in VR Put on your headset and look around. You should be able to see all 3 sensors present in the VR environment. This will confirm that you’ve properly configured all 3 sensors. Stand in the center of the 3 sensors while looking forward toward the middle of the front two sensors. Press the Trigger button as instructed. You’ll see beams coming out of all of the sensors and scanning your position. Step 7: Enjoy Your Experimental 360º / Roomscale Setup Congratulations, you’ve now completed your experimental 3-sensor setup and are ready to enjoy 360° and roomscale experiences.
