BRAIN COMPUTER INTERFACE FOR AUGMENTED REALITY

Smart overview of the Invention

An innovative brain-computer interface (BCI) is designed to be integrated into a headset featuring an augmented reality (AR) display. The system consists of multiple components, including sensors, a processing module, biofeedback devices, and a battery. The printed circuit board (PCB) plays a crucial role by reading bio-signals, providing feedback, and processing these signals into outputs that stimulate various sensory systems of the user, enhancing their experience through a closed-loop mechanism.

Challenges with Traditional BCIs

Conventional BCIs often rely on external devices for processing brain signals, necessitating complex setups with multiple wires that can lead to failures if damaged. These systems are typically cumbersome, time-consuming to set up, and location-dependent. Additionally, the flat design of traditional PCBs limits their practicality in real-world applications, highlighting the need for a more efficient and user-friendly BCI solution.

Enhanced Design Features

The proposed BCI headset incorporates a contoured PCB that conforms to the shape of the human head. This flexible design allows for improved comfort and mobility while processing bio-signals internally. The PCB consists of three distinct areas: one for signal input, another for processing and output generation, and a third for providing haptic and audio feedback. This internal processing capability reduces reliance on external devices, making the system more portable and self-sufficient.

Feedback Mechanism and Applications

The headset's design facilitates a feedback loop where sensory stimulation leads to altered neural signals in the user's brain, reinforcing new behaviors and experiences. Outputs can include visual cues on the AR display or haptic feedback through inflatable bags or electrical stimulation. This technology holds potential for assisting individuals with communication difficulties or disabilities by enabling them to control their environment through thought-driven commands.

Versatile Configurations

The BCI system can be configured in various ways, such as a fully integrated AR headset or as an accessory to existing AR/VR systems. Potential applications range from standalone EEG devices for visual evoked potential matching to miniaturized implants communicating wirelessly with smart contact lenses. This versatility allows for widespread use in diverse settings, particularly benefiting those who require enhanced communication and control capabilities.
