Cyber-Physical System for Gait Analysis and Fall Prevention by Embedded EEG-EMG Computing
Brief Abstract: Development of non-invasive, wireless embedded system for gait analysis and preventing involuntary movements including fall. The system operates with synchronized and digitized data samples from 8 EMG (limbs) and 8 EEG (motor-cortex) channels. An embedded Altera Cyclone V FPGA operates the real-time signal pre-processing and the computation (resource utilization: 85.95% ALMs, 43283 ALUTs, 73.0% registers, 9.9% block memory; processing latency < 1ms). The system is able to prevent fall enabling the actuator in 168ms, i.e., better than the normal human time reaction (300ms).

Research field #2: Bioengineering, BCI, P300
Brain to Computer Connections: a Fast Time Domain Approach for BCI applications
Brief Abstract: Development of a P300-based Brain Computer System for the remote control of a mechatronic actuator, such as wheelchair, or even a car, driven by EEG signals to be used by tetraplegic and paralytic users or just for safe drive in case of car. The EEG data are collected by 6 electrodes from the parietal-cortex area and online classified by a linear threshold classifier, basing on a suitable stage of Machine Learning (ML). The main improvement in remote device piloting by EEG, regards the approach used for the intentions recognition. In this project, the classification is based on the P300 and not just on the average of more not well identify potentials. This approach reduces the number of electrodes on the EEG helmet. The ML stage is based on a custom algorithm (t-RIDE- see Ref.1) which trains the following classification stage on the user’s “cognitive chronometry”. Tthe BCI presents a functional approach for time-domain features extraction, which reduce the amount of data to be analyzed, and then the system response times.
