Brain-Controlled VR Games

Description:

Using brain activity to interact with virtual reality

Commissioned by CortiVision, we developed a set of PC VR games designed to work with the BioVR Spotlight EEG headset provided by the client. Our task was to create engaging game scenarios that respond to the user’s level of focus, using real-time brain activity signals sent via the device’s dedicated API.

Hands-free interaction – EEG data as input

The games do not require traditional VR controllers. Instead, selected actions within the games are triggered by the user’s mental state – specifically, their ability to concentrate or imagine movement. Our team implemented EEG signal handling in Unity and developed a smooth integration layer to turn neurofeedback into gameplay interaction.

Two mental training scenarios

We delivered two core game types:

• N-back task: a classic working memory challenge where sustained attention is used to influence the environment in a neurofeedback loop.
• Motor Imagery: the user imagines left or right hand movement, and the EEG input drives corresponding actions in the VR space — ideal for training and research purposes.

Focus-driven gameplay for research and training

This project demonstrates how EEG-based input can enrich virtual reality experiences in both research and cognitive training contexts. The EEG hardware and its API were fully delivered by the client — our role was to design and build functional VR games and handle the technical integration.
