 Electroencephalography, e.g., is a non-invasive technique used to measure electrical activity in the brain. It can be used to control wheelchairs for people with motor neuron diseases such as a myotrophic lateral sclerosis, ALS. Despite its potential benefits, the application of e.g. driven wheelchairs remains limited due to technical difficulties and safety concerns. This paper reviews the current state of the art and the various models employed in the literature, while also highlighting the challenges and opportunities associated with the technology. Additionally, it discusses recent advances in the field and provides insight into future directions. This article was authored by Mohamed YM Nasir and Silvia Bhattacharya.
