A non-invasive brain-computer interface (BCI) capable of translating neural signals into game inputs was demonstrated at the World Artificial Intelligence Conference (WAIC) in Shanghai. The technology allows players to control games, such as Black Myth: Wukong, using only their brain waves.
The system, showcased by AI enthusiast Huang Lu, utilizes Steady-State Visual Evoked Potentials (SSVEP). This method involves projecting visual targets onto the screen that flash at different frequencies. According to Huang Lu, the user's brain generates unique electroencephalogram (EEG) signals in response to these flashes, which are detected by a headset and then translated into in-game commands. The calibration process for each user reportedly takes approximately five minutes.
This BCI technology offers a potential new avenue for gamers with limited mobility or physical disabilities. However, the use of flashing targets raises concerns about its suitability for individuals with photo-sensitive epilepsy. Furthermore, BCIs can present challenges in gaming due to latency, though demonstrations have shown that overcoming these delays is possible.
Beyond gaming, related BCI technology was also on display at WAIC 2026. BrainCo presented a non-invasive BCI system where users wear an EEG headset to remotely control robotic limbs and humanoid robots. AI algorithms decode the wearer's brain signals to identify motor intent, which is then converted into commands for the robot, with the entire process taking under 200 milliseconds. Despite this rapid response, the article notes that even a small delay can be significant in applications like controlling a robot to catch a falling object.
