Special Issue Information

Dear Colleagues,

In recent years, new human–machine interfaces (HMIs) have been developed to facilitate communication and interactions between people with severe motor difficulties and their environment, or even with damaged parts of their own body. By using technologies such as the Internet of Things (IoT) and artificial intelligence techniques, they can satisfy their daily life needs by remotely accessing, controlling and monitoring devices through different biological signals, also known as biosignals, that can come from different parts of their body. A wide variety of these biosignals can be used to interact with HMIs. The use of each will depend on the purpose of the interface and the motor capabilities of the user. The three most common types of biological signals are: muscular, ocular and cerebral. This Special Issue focuses on the analysis and development of interfaces based not only on brain signals that capture the biosignals produced by the user's neural activity through noninvasive techniques such as electroencephalography (EEG), but also on other biosignals, or a combination of several of them, in order to improve the interaction with the environment and the patient's progress in performing activities such as daily living, a rehabilitation program or their usual therapy based on the joint data extracted.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Modern deep neural networks (DNNs) have shown promising results in brain studies involving multi-channel electroencephalogram (EEG) signals. The representations produced by the layers of a DNN trained on EEG signals remain, however, poorly understood. In this paper, we propose an approach to interpret deep representations of EEG signals. Our approach produces spatio-spectral feature images (SSFIs) that encode the EEG input patterns that activate the neurons in each layer of a DNN. We evaluate our approach using the PhyAAt dataset of multi-channel EEG signals for auditory attention. First, we train the same convolutional neural network (CNN) architecture on 25 separate sets of EEG signals from 25 subjects and conduct individual model analysis and inter-subject dependency analysis. Then we generate the SSFI input patterns that activate the layers of each trained CNN. The generated SSFI patterns can identify the main brain regions involved in a given auditory task. Our results show that low-level CNN features focus on larger regions and high-level features focus on smaller regions. In addition, our approach allows us to discern patterns in different frequency bands. Further SSFI saliency analysis reveals common brain regions associated with a specific activity for each subject. Our approach to investigate deep representations using SSFI can be used to enhance our understanding of the brain activity and effectively realize transfer learning. Full article
