Ten participants with various degrees of sight loss navigated in unfamiliar indoor and outdoor environments, while their electroencephalogram (EEG) and electrodermal activity (EDA) signals were being recorded. In this study, the cognitive load of the tasks was assessed in real time based on a modification of the well\u2010established event\u2010related (de)synchronization (ERD\/ERS) index. We present an in\u2010depth analysis of the environments that mostly challenge people from certain categories of sight loss and we present an automatic classification of the perceived difficulty in each time instance, inferred from their biosignals. Given the limited size of our sample, our findings suggest that there are significant differences across the environments for the various categories of sight loss. Moreover, we exploit cross\u2010modal relations predicting the cognitive load in real time inferring on features extracted from the EDA. Such possibility paves the way for the design on less invasive, wearable assistive devices that take into consideration the well\u2010being of the VIP.<\/jats:p>","DOI":"10.1155\/2018\/8971206","type":"journal-article","created":{"date-parts":[[2018,2,28]],"date-time":"2018-02-28T23:46:01Z","timestamp":1519861561000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Cognitive Load Assessment from EEG and Peripheral Biosignals for the Design of Visually Impaired Mobility Aids"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6860-9723","authenticated-orcid":false,"given":"Charalampos","family":"Saitis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2138-8334","authenticated-orcid":false,"given":"Mohammad Zavid","family":"Parvez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8068-5916","authenticated-orcid":false,"given":"Kyriaki","family":"Kalimeri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,2,28]]},"reference":[{"key":"e_1_2_9_1_2","unstructured":"World Health Oganization (WHO) Media Centre Visual Impairment and Blindness Fact Sheet no. 282 2014 http:\/\/www.who.int\/mediacentre\/factsheets\/fs282\/en\/Available [Accessed February 13 2014]."},{"key":"e_1_2_9_2_2","first-page":"272","volume-title":"Foundations of orientation and mobility","author":"William Wiener R.","year":"1997"},{"key":"e_1_2_9_3_2","unstructured":"VirtanenA.andKoskinenS.
