Is your Tobii Eye Tracker refusing to connect? Don't worry, you're not alone! Many users encounter connection problems with their Tobii devices. The good news is that most of these issues are easily resolved with a bit of troubleshooting. This guide will walk you through various steps to diagnose and fix the problem, getting you back to gaming, research, or whatever awesome application you use your eye tracker for. Let's dive in!

Preliminary Checks: The Obvious (But Important) Stuff

Before we get into the nitty-gritty, let's cover the basics. Sometimes the simplest solutions are the ones we overlook. These preliminary checks will help rule out common causes of Tobii Eye Tracker connection failure.

• Cable Connection: This might seem obvious, but double-check that the USB cable connecting your Tobii Eye Tracker to your computer is securely plugged in at both ends. A loose connection is a frequent culprit. Try unplugging and re-plugging the cable, ensuring it clicks into place.
• USB Port: Not all USB ports are created equal. Some ports might not provide enough power or bandwidth for the Tobii Eye Tracker to function correctly. Try connecting the device to a different USB port on your computer, preferably a USB 3.0 port (usually blue). Avoid using USB hubs, as they can sometimes cause power or data transfer issues. Connecting directly to a port on your motherboard is generally the most reliable option.
• Cable Integrity: Inspect the USB cable for any signs of damage, such as cuts, fraying, or kinks. A damaged cable can prevent proper communication between the eye tracker and your computer. If you suspect the cable is damaged, try using a different USB cable to see if that resolves the issue. A high-quality, shielded cable is recommended for optimal performance.
• Power: Ensure your computer is powered on and not in sleep or hibernation mode. Sometimes, the USB ports are disabled or have reduced power in these modes. A full restart of your computer can often resolve power-related issues.
• Software Conflicts: In rare cases, other software running on your computer might interfere with the Tobii Eye Tracker's connection. Try closing any unnecessary applications, especially those that use USB devices or interact with hardware drivers. Antivirus software or firewalls can also sometimes cause conflicts. Temporarily disabling these programs (with caution) can help determine if they are the source of the problem.

Software Solutions: Drivers and Tobii Software

If the physical connections seem fine, the problem likely lies in the software. Ensuring you have the correct drivers and software installed and configured properly is crucial for a stable connection. Let's explore the software side of things.

• Driver Installation/Update: The Tobii Eye Tracker relies on specific drivers to communicate with your computer. Outdated or corrupted drivers can cause connection problems. To update or reinstall the drivers:
  • Device Manager: Open Device Manager (search for it in the Windows search bar). Look for the Tobii Eye Tracker under the "Human Interface Devices" or "Cameras" category. If you see a yellow exclamation mark next to the device, it indicates a driver problem. Right-click on the Tobii Eye Tracker and select "Update driver". Choose the option to search automatically for updated drivers. If that doesn't work, try uninstalling the device (right-click and select "Uninstall device") and then re-plugging in the eye tracker. Windows should automatically attempt to reinstall the drivers.
  • Tobii Website: Visit the official Tobii website and download the latest drivers for your specific eye tracker model. Follow the installation instructions provided on the website. Manually installing the drivers can sometimes resolve issues that automatic driver updates miss.
• Tobii Eye Tracking Software: Make sure you have the Tobii Eye Tracking software installed. This software is necessary for configuring and using the eye tracker. Download the latest version from the Tobii website and follow the installation instructions. Ensure the software is running in the background.
• Software Compatibility: Check that the Tobii Eye Tracking software is compatible with your operating system. Refer to the Tobii website for compatibility information. Using an incompatible version of the software can lead to connection problems and other issues.
• Software Updates: Keep the Tobii Eye Tracking software up to date. Software updates often include bug fixes and improvements that can resolve connection issues. Check for updates within the Tobii software or on the Tobii website.
• Firewall/Antivirus: Sometimes, firewalls or antivirus software can block the Tobii Eye Tracking software from communicating with the eye tracker. Add the Tobii software to the list of exceptions in your firewall and antivirus settings. This will allow the software to communicate freely without being blocked.

Advanced Troubleshooting: Digging Deeper

If the basic checks and software solutions haven't worked, it's time to delve into some more advanced troubleshooting steps. These steps involve checking system settings and configurations that might be affecting the Tobii Eye Tracker's connection.

• USB Selective Suspend: Windows has a feature called USB selective suspend, which can disable USB ports to save power. This can sometimes interfere with the Tobii Eye Tracker's connection. To disable USB selective suspend:
  • Open Control Panel. Navigate to Hardware and Sound > Power Options > Edit Plan Settings. Click on "Change advanced power settings". Expand the "USB settings" section and set "USB selective suspend setting" to "Disabled". Apply the changes and restart your computer.
• Driver Conflicts: Sometimes, other USB devices connected to your computer can conflict with the Tobii Eye Tracker's drivers. Try disconnecting any unnecessary USB devices to see if that resolves the issue. If you identify a specific device that's causing the conflict, try updating its drivers or using a different USB port.
• BIOS Settings: In rare cases, certain BIOS settings can affect USB device compatibility. Consult your computer's motherboard manual for instructions on accessing the BIOS settings. Look for settings related to USB configuration and ensure they are set to their default values. If you're not comfortable modifying BIOS settings, it's best to consult with a computer technician.
• Operating System Issues: In extreme cases, the problem might be related to the operating system itself. Corrupted system files or conflicting software can sometimes cause USB device connectivity issues. Consider running a system file checker (SFC) scan to repair any corrupted system files. If the problem persists, you might need to consider reinstalling your operating system.
• Hardware Failure: Though less common, the Tobii Eye Tracker itself might be faulty. If you've tried all the troubleshooting steps and the device still won't connect, it's possible that there's a hardware problem. Contact Tobii support for assistance with diagnosing and potentially repairing or replacing the device.
