Review of real brain-controlled wheelchairs

Abstract

Abstract. This paper presents a review of the state of the art regarding wheelchairs driven by a brain-computer interface (BCI). Using a brain-controlled wheelchair (BCW), disabled users could handle a wheelchair through their brain activity, granting autonomy to move through an experimental environment. A classification is established, based on the characteristics of the BCW, such as the type of electroencephalographic (EEG) signal used, the navigation system employed by the wheelchair, the task for the participants, or the metrics used to evaluate the performance. Furthermore, these factors are compared according to the type of signal used, in order to clarify the differences among them. Finally, the trend of current research in this field is discussed, as well as the challenges that should be solved in the future.

Brain-Computer Interface application: auditory serial interface to control a two-class motor-imagery-based wheelchair

“…In addition, these studies should have the same participant experience level, tasks and metrics to allow a direct comparison between them as it has been manifested in previous reviews [14, 34]. …”

Taking the eye road: A new access method for powered mobility in amyotrophic lateral sclerosis

“…Some A caveat to the exciting developments in PWC access is that only a small minority of studies have tested these control methods with potential users. 14…”

“…19 Users also identified a number of difficult driving situations that may benefit from automation, such as navigating crowded places, long distances, narrow environments, and backing up. 19 Sparse selection of destination endpoints by the user could be paired with driverless navigation, 14 potentially reducing fatigue and attentional devotion to the driving task. Intelligent features, such as collision avoidance, could positively impact users' participation in social activities while decreasing the fear of accidents.…”

Estado del Arte en Neurotecnologías para la Asistencia y la Rehabilitación en España: Tecnologías Fundamentales

“…Dicho paradigma debía evitar empeorar las prestaciones del sistema BCI, por lo que se basaba en la discriminación de sólo dos tareas mentales (Ron-Angevin et al, 2009b). La evolución de dicho paradigma fue pasando por varias fases, probándose en entornos virtuales (Velasco-Álvarez et al, 2010), robots y, finalmente, sillas de ruedas , Fernández-Rodríguez et al, 2016, siendo esto último objeto de investigación actual del grupo UMA-BCI. Finalmente, la tercera línea de investigación está enmarcada en el proyecto LICOM (DPI2015-67064-R).…”
