Nowadays, the virtual reality (VR) market has a wide range of headsets and controllers. Among them, the Valve Index Controllers and HTC Vive Cosmos are two popular VR devices.

Both have their own unique features that cater to different preferences of users. However, some users may wonder if they can use Valve Index Controllers with the HTC Vive Cosmos. In this article, we will explore this question in-depth.

Valve Index Controllers

The Valve Index Controllers, also known as Knuckles controllers, are designed to work with the Valve Index headset. They are known for their advanced features such as finger tracking, grip detection, and pressure sensitivity. These controllers provide a more immersive experience by allowing users to interact with objects in VR games more realistically.

HTC Vive Cosmos

The HTC Vive Cosmos is a standalone VR headset that offers inside-out tracking, meaning it doesn’t require external sensors for movement tracking. It comes with its own set of controllers that are similar in design to the original HTC Vive controllers.

Can You Use Valve Index Controllers With HTC Vive Cosmos?

The short answer is yes; you can use Valve Index Controllers with the HTC Vive Cosmos. However, it requires some additional steps and software installation.

SteamVR Compatibility

The first requirement is SteamVR compatibility. Both devices must have SteamVR installed on your computer to work together properly.

Base Stations

Valve Index Controllers require base stations for tracking movement accurately within the VR space. These base stations emit infrared signals that are detected by sensors on the controllers. The HTC Vive Cosmos uses inside-out tracking technology and doesn’t require external base stations.

To use Valve Index Controllers with the HTC Vive Cosmos, you’ll need to purchase separate base stations or borrow them from someone who has them already set up for their Valve Index headset.

Controller Firmware Update

Once you have the base stations set up, you’ll need to update the firmware on your Valve Index Controllers to make them compatible with the HTC Vive Cosmos. This can be done through SteamVR settings.

Third-Party Software

To make Valve Index Controllers work with the HTC Vive Cosmos, you’ll also need to install third-party software such as OpenVR Space Calibrator or Natural Locomotion. These applications help to ensure that your controllers are calibrated correctly and work seamlessly with the HTC Vive Cosmos.


In summary, it is possible to use Valve Index Controllers with the HTC Vive Cosmos, but it requires additional hardware and software installation. If you already have both devices and want a more immersive VR experience, then it’s worth giving it a try. However, if you’re looking for a simple plug-and-play solution, then sticking with the original controllers that come with the headset may be a better choice.
