🧠⌨️ An intuitive, bimanual, high-throughput QWERTY touch typing neuroprosthesis for people with tetraplegia

What if people with paralysis could type as naturally and quickly as anyone else — just by attempting finger movements? This project brings that vision to life.

🧠 Highlights
• Provides a bimanual QWERTY keyboard interface controlled by attempted finger movements
• Uses a recurrent neural network (RNN) to decode neural signals into characters in real-time
• High throughput: up to 110 characters per minute, 22 words per minute, with a 1.6% word error rate
• Requires only ~30 calibration sentences to achieve accurate decoding
• Works for participants with ALS or high cervical spinal cord injury, including those unable to use eye-gaze or speech-based systems
• Typing is self-paced, intuitive, and familiar, leveraging memory of standard keyboard layouts

💡 Why it matters
This iBCI typing neuroprosthesis provides fast, free-form digital communication for individuals with tetraplegia. By mimicking natural finger movements, it offers a clinically viable, easy-to-learn, and high-accuracy solution, surpassing current state-of-the-art hand motor iBCI systems and offering independence and privacy in communication.

The Unicorn Recorder is a powerful application that allows you to seamlessly acquire, visualize, and record data from either the Unicorn Hybrid Black or Unicorn Naked BCI. In this demonstration, Martin showcases SSVEP examples using Unicorn Recorder version 1.24.00.

SSVEP is a technique used to detect brain responses to visual stimuli, and the Unicorn Hybrid Black’s high-quality EEG recording capabilities made it the perfect tool for this experiment. The device’s precision and reliability allowed for accurate detection of visual evoked potentials, paving the way for advanced research in areas like:
✅ Brain-computer interfaces (BCI)
✅ Neurofeedback
✅ Cognitive state monitoring

BCI Award 3rd place winner 2025: An implantable Brain-Spine Interface restoring lower limb movements after complete spinal cord injury 🧠🚶‍♀️⚡

Spinal cord injury disrupts communication between brain and legs, often causing permanent paralysis. Our team is thrilled to submit to the BCI Award 2025 our latest evolution of the Brain-Spine Interface: a fully implantable system that restored overground walking in two women with complete sensorimotor spinal cord injury.

🧠 Highlights
• Upgraded ECoG decoding with high stability and accuracy
• Real-time spinal cord stimulation enabling highly selective motor control
• AI-driven decoding (BrainGPT) + automated stimulation mapping
• One cortical implant + portable design for home use
• Participants stood and walked overground using a front-wheel walker

💡 Why it matters
These results show the potential of a brain-spine digital bridge to restore mobility to people with complete paralysis—addressing a population previously thought unreachable by BCI therapy.

Who remembers g.tec's intendiX system?🤔 It was the first commercially available spelling system based on BCI technology, released in 2009. At that time, we used g.MOBIlab to acquire data from 8 passive EEG channels. The electrodes were made of gold, and abrasive gel was used to achieve low impedance. g.MOBIlab transmitted the data via Bluetooth to the computer, where the software allowed users to select characters to form words and sentences. The name intendiX fit very nicely with the system because users could "intend" to select the variable X, a concept that did not exist at that time. In 2010, we showcased intendiX at CeBit, the world's largest IT trade show, and were flooded by visitors fascinated by BCI technology 🤗 During CeBit, we received several hundred thousand Google hits when searching for intendiX, compared to nearly zero before CeBit.

This post nicely illustrates people's perceptions of BCI technology 14 years ago: https://tinyurl.com/y7thjzkv

Imagine the life-changing moment when someone with Conus Cauda Syndrome regains movement—thanks to recoveriX, g.tec’s groundbreaking neurorehabilitation system powered by 25 years of Brain-Computer Interface (BCI) expertise😍😍 recoveriX is a neurorehabilitation system designed for stroke, multiple sclerosis (MS), and Parkinson's patients. The system is medically certified, safe, and effective, and is currently used in more than 20 countries worldwide.

Patients are required to imagine motor movements 6,000 to 8,000 times. The BCI system is capable of detecting these imagined movements in real-time and triggers functional electrical stimulation in the hand or foot. This reconnects cognitive functions with motor functions, allowing patients to regain movement in their hands/arms and feet/legs. Remarkably, this therapy can be effective even 10, 20, or 30 years after a stroke or the onset of MS or Parkinson's. It is never too late to begin treatment. The joy on a patient's face when a paralyzed hand suddenly moves again is truly unforgettable.

g.tec started developing brain-computer interfaces (BCI) about 20 years ago, after presenting the first portable BCI system in 1999 at the BCI Meeting in Rensselaerville, New York. This device had an EEG amplifier within the floppy drive housing of an HP laptop system. From there on, BCI technology evolved rapidly:

In 1999, we demonstrated the first BCI session with 100 % accuracy using a motor imagery BCI system with Common Spatial Patterns. In 2007, we released the first commercial BCI for home use, called intendiX. This P300 speller could achieve 100 % accuracy after only 5 minutes of training. Later in 2013, code based VEPs allowed users to control a robotic device with an accuracy of 98 % in a continuous control task and play World of Warcraft. Around this time, g.tec also became more active with ECoG recordings, which have led to several publications and the cortiQ system. The high spatial resolution of ECoG recordings has made it possible to decode much finer finger movements than noninvasive recordings, and to analyze under-explored brain regions like the fusiform face area in real-time using high-gamma activity.

In 2014, g.tec introduced wireless dry and wet EEG recording systems using active electrodes. This major achievement is still boosting BCI performance and user experience worldwide by improving the signal to noise ratio and ease of use. But what does the future hold for brain-computer interfacing? There are many exciting new directions, and g.tec is focused on extending BCIs with non-invasive and invasive neuromodulation and stimulation technology to further increase accuracy and to broaden application areas.
