Vive Tracking Vive Trackers are small motion-tracking devices designed to bring real-world objects into virtual environments. While they are commonly used in VR setups to track body movements or props, they can also function as standalone tracking devices in software like TouchDesigner. Each tracker sends precise position and rotation data, making them useful for interactive installations, motion capture, and experimental media projects. By integrating them into creative software, we can map real-world movement onto digital visuals, audio, or other interactive elements. Vive Trackers What Are Vive Trackers?

By integrating them into creative software, we can map real-world movement onto digital visuals, audio, or other interactive elements. Setting Up Vive Trackers with a Vive Pro & SteamVR To use Vive Trackers standalone (without VR controllers), follow these steps: 1. Hardware Setup A. Prepare Your Equipment Vive Pro Headset (even if unused, SteamVR requires it to be connected) Vive Trackers (paired via dongles or directly with the headset) Base Stations (for tracking) USB Dongles ( when using multiple trackers ) B. Position the Base Stations Mount at least two base stations (2.0 recommended) above head height at opposite corners of your space, at a maximum of 5 meters apart.  Ensure they are powered and have a clear view of the area.  2. Install & Launch SteamVR Install Steam and SteamVR if not already installed. Connect the Vive Pro headset to ensure SteamVR initializes correctly. 3. Pair the Vive Trackers Turn on each tracker by pressing the power button until the light turns blue . Open SteamVR and go to Devices > Pair Controller (works for Trackers too). Select "Vive Tracker" and follow the instructions. If using a USB dongle , plug it into your PC and ensure the tracker is paired to it.  Place the extension cradles at 45 cm from the computer for stable tracking. Once paired, the tracker’s LED will turn green . 4. Configure the Trackers in SteamVR Open SteamVR > Devices > Manage Vive Trackers Set each tracker's role (e.g., “Held in Hand” or “Disabled” if using it just for positional data). If needed, attach them to an object or a strap (e.g., for body tracking). This can be done with a camera-mount, ¼-inch screw size. 5. Use in TouchDesigner  Open TouchDesigner and use the OpenVR CHOP and set it to 'trackers' to read positional and rotational data. Trackers send position (XYZ) and rotation (quaternion or Euler angles) . You can map this data to visuals, interactive elements, or other media. 6. Use in other software Use GazeboOsc   to pick up the Tracker signals & send them to other software (e.g. Isadora) that can handle OSC. Troubleshooting Check if the tracker has a uninterrupted line of vision with the base stations & headset. If a tracker is  not detected , reset it by holding the power button for 10 seconds . Ensure no reflective surfaces interfere with the base stations. Restart SteamVR if tracking is unstable. Vive Ultimate Trackers What Are Vive Ultimate Trackers? The Vive Ultimate Tracker is HTC’s next-generation tracking device designed to improve motion tracking in VR and standalone applications. Unlike the regular Vive Tracker , which relies on external base stations , the Ultimate Tracker features inside-out tracking , meaning it uses built-in cameras to track its position without needing external sensors. This makes the Ultimate Tracker more portable and flexible, as it doesn’t require a dedicated tracking area or base stations. Comparison: Ultimate Tracker vs. Regular Vive Tracker Feature Vive Ultimate Tracker Vive Tracker Tracking Method Inside-out (built-in cameras) Outside-in (Base Stations), infrared. Base Stations Needed ❌ No ✅ Yes (Lighthouse) Connection Type Wi-Fi 6E / USB-C Dongle USB dongle (2.4 GHz) Battery Life ~7 hours ~7 hours Size & Weight Slightly smaller & standalone Various sizes depending on the. model (1,2,3) & requires  base station setup Latency Slightly higher due to processing Lower latency with base stations Connection Built-In camera's, do not cover. Sometimes loses connection. Calibrates through mapping setup at startup. When connection is lost, move back to the centre point of callibration Base stations, do not cover the tracker for line of sight connection, then stable.  Zero point connected to headset initial calibration  placement. This can be updated it TD Best Use Case Portable, flexible tracking without a defined play area High-precision tracking in controlled spaces When to Use Each? Use the Vive Ultimate Tracker if: You need standalone, flexible tracking without base stations & headset. You’re working in large or dynamic spaces where base stations aren’t practical. In a well-lit enviroment (but not too much direct sunlight) Use the Vive Tracker if: You need high-precision tracking with minimal latency. You’re working in a controlled space with base stations . You need compatibility with existing VR setups (e.g., Vive Pro). When working in low-lit spaces. 1. Hardware Setup A. What You Need Vive Ultimate Tracker(s), preferably with straps Usb -c Hub & extension cradle PC ( windows only ) with Vive software installed USB-C Cable (for wired mode, firmware updates & charging) B. Charging & Powering On Charge the Ultimate Tracker via USB-C before first use. Press the power button until the LED lights up Blue. 2. Connect to Vive Wireless Hub Install & Open the Vive Wireless Hub Software Download & install Vive Hub from HTC’s official site. Launch Vive Hub on your Windows PC. Pair the Ultimate Tracker (link for steps on the Vive website, link) Connect the USBDongle to your computer at least 45 cm away for decent tracking. Open  Vive Hub and go to the settings, choose Vive Ultimate Trackers Check for firmware update & do them if necessary (app explains the steps) . Pair New : Follow the on screen instructions to pair each Ultimate Tracker.  Tracker Mapping click on Tracker setup & follow the steps on screen>   3. Open SteamVR Once trackers are mapped in Vive Hub , launch SteamVR . SteamVR should now detect the Ultimate Trackers automatically. You can check and adjust tracking roles under Devices > Manage Vive Trackers in SteamVR. 4. Use in TouchDesigner Open TouchDesigner and use the OpenVrChop & set it to  Trackers to receive position & rotation data. Map the data to visuals, interactions, or animations as needed. 5. Use in other software Use  GazeboOsc   to pick up the Tracker signals & send them to other software (e.g. Isadora) that can handle OSC. Troubleshooting If SteamVR doesn’t detect trackers, temporarily turn on the headset or  restart SteamVR and Vive Hub . Ensure the tracker is properly mapped in Vive Hub before launching SteamVR. Reset a tracker by holding the power button for 10 seconds . When tracking is lost, return it to the zero point of the callibration Since the Ultimate Tracker uses inside-out tracking , ensure there are enough visual markers and light in the environment for stable tracking. Dark furniture may cause tracking issues.
