We have now sufficient evidence that using electrical biosignals in the field of Alternative and Augmented Communication is feasible. Additionally, they are particularly suitable in the case of people with severe motor impairment, e.g. people with high-level spinal cord injury or with locked-up syndrome. Developing solutions for them implies that we find(More)
Assistive technology is dedicated to people who suffers from disabilities or pathologies that limit their daily life. It provides support in alternative communication, accessibility, mobility and cognitive domains. An example of this type of technology is the electric wheelchair that allows the person to move more freely and independently. However, most(More)
We have now sufficient evidence that the use of bioelectric signals in the field of Augmented and Alternative Communication (AAC) is feasible. Moreover they are particularly suitable for people with severe motor disabilities, for example, people with high levels of spinal cord injury or with locked-in syndrome. The development of solutions for this kind of(More)
New research reports shows that important progresses for controlling electric-powered wheelchair have been made recently aiming people with severe disabilities. In fact, a significant amount of people affected by those physical disabilities still cannot take advantage of autonomous mobility, even electronic or automated ones. For those people, the use of(More)
Spasticity is a motor disorder that affects over 12 million people worldwide. Its pathophysiology is rather complex and might be caused by cortical problems or spinal cord injury, for example, and involves different circuitries and networks. The measurement of spasticity is very important for providing better support for the patients, both in diagnosis and(More)
People with severe motor disabilities present reduction or absence of motor control. However, in different stages of these conditions, some people can perform voluntary movements of low amplitude. This paper presents the development of an Human Computer Interface - HCI - for controlling an augmented and alternative communication system. The device consists(More)
