Trinus Hand is a free Android application developed by Odd Sheep that enhances your SteamVR experiences. It transforms your smartphone into a 3dof (3 degrees of freedom) controller for your SteamVR games, increasing the level of immersion.

With Trinus Hand, you have the option to use a single device to emulate both controllers, with separate buttons for each controller. Alternatively, you can use two smartphones for full control.

This application requires Bluetooth connectivity on both your PC and smartphone, as well as gyroscope sensors on your smartphone. It is currently only compatible with Trinus PSVR.

Using Trinus Hand is simple. Just pair your Android device via Windows Bluetooth settings, run the Trinus PC server (compatible with Trinus PSVR), choose the device(s) in the Hand Tracker tab, and start your VR session.

While the application is free, there is an in-app purchase option available. By default, you have access to all buttons. However, if you want to fully customize your experience, you can change the button size and placement, and even assign actions to physical volume keys with the in-app purchase.
