Visual Interface System for Improved Navigation and Accessibility Through EEG, Allowing for an EEG-driven Mobility Platform Offering Wheelchair-enabled Engagement and Rehabilitation (EMPOWER): An Early Feasibility Study (EFS) of Safety and Efficacy in Subjects With Severe Quadriplegia

Neuralis, developed by Synaptrix Labs, is an innovative assistive technology engineered to restore mobility and independence for individuals grappling with severe neuromuscular conditions. This cutting-edge device operates through a discreet and non-invasive EEG headset, comprising strategically placed dry sensors at on the occipital lobe, precisely targeting the visual cortex region.

The key breakthrough lies in Neuralis' capability to extract brain activity from subtle eye movements. Through this interaction, Neuralis decodes subtle EEG signals, effectively translating them into precise wheelchair navigation commands.

The device interfaces seamlessly with a user-friendly Neuralis mobile app, serving as the central control hub. This intuitive application handles calibration settings, connectivity, and destination selections through a simplified visual click-based protocol. The slim BCI headset captures EEG data, transmitting it via Bluetooth to the connected smartphone. Subsequently, the data is relayed to a secure cloud server, which houses an advanced computational infrastructure employing edge computing principles for optimal response times.

Within this cloud environment, a proprietary machine learning pipeline for EEG decoding and intent classification operates. Certain latency-sensitive steps run on the phone, while the cloud handles additional model training and personalization, leveraging scalable processing power. This dynamic architecture ensures a swift and near-instantaneous translation of the user's movement intentions into seamless wheelchair maneuverability.

What sets Neuralis apart is its ability to deliver robust functionality in a discreet, user-friendly manner. Its lightweight construction, comprising only four sensors, maximizes comfort while capturing essential visual cortex signals vital for nimble maneuvering. This fusion of advanced neurotechnology and user-centric design positions Neuralis as a significant leap forward in assistive devices, bridging the gap between usability and high-performance functionality for individuals with severe neuromuscular conditions.
