Abstract This presentation unravels the latest strides and existing challenges in the realm of neuro-rehabilitation, with a specific focus on the applications of brain-computer interface (BCI) to improve the quality of life for both patients and senior individuals. We're exploring new territory by integrating principles of slots game design into our techniques, making neuro-rehabilitation more engaging and effective.
Firstly, we showcase an innovative method enabling control of a robotic arm using brain signals, capturing the complexity and flexibility often seen in slots gaming. By decoding motor commands from Electroencephalography (EEG) recordings, users can execute or mentally simulate complex upper limb movements. This process borrows from the intricate algorithms at work in
slots games, assuring fair and unpredictable results.
Taking a cue from the user interaction inherent in slots, we've created a brain-controlled wheelchair system that responds to the user's level of concentration. The user focuses on a specific vibrational stimulus, similar to selecting symbols in a slots game, enabling the wheelchair to navigate accordingly. This use of spatial-frequency features has significantly increased the system's accuracy.
Building on this, we have designed a lower-limb exoskeleton control system, applying the principles of interactivity and engagement common to slots. Despite the challenging task of distinguishing EEG signals amidst environmental interference, our convolutional neural network (CNN)-based signal processing algorithm, inspired by game development complexity, is able to robustly interpret user intentions.
Furthermore, we've developed a BCI-based motor rehabilitation system that identifies various walking speed gaits. By analyzing EEG signals during continuous exoskeleton-assisted walking, we can accurately classify different gaits. This approach mirrors the dynamic nature of slots games, adapting to user actions, and demonstrates the potential of integrating game development principles into neuro-rehabilitation.
In essence, we're reimagining neuro-rehabilitation by applying the engaging and adaptive nature of slots gaming. This innovative blend has led to the creation of more dynamic, responsive, and ultimately effective BCI systems, enhancing the quality of life for patients and the elderly alike.
