Abstract. The aim of this paper is to compare two virtual keyboards for people with cerebral palsy; many of these users have difficulty performing actions using their upper limbs due to large numbers of unwanted movements. The first is a classical QWERTY type keyboard, called Clavicom NG. The second is the K-Hermes proposed in this paper. K-Hermes is a reduced and monotape keyboard; its entry principles are inspired by the T9 keyboard. The aim of the experiment is to demonstrate the reduced effort and increased speed of typing with the keyboard suggested for people with Cerebral Palsy.
Abstract.Communication is an important act in the development and empowerment of human beings. Through language, humans communicate their needs, desires, moods... Unfortunately, many physical and mental disabilities deprive some people of such communication means. Nowadays various Augmentative and Alternative Communication (AAC) systems exist in order to help people with disabilities. Virtual keyboards are the most common AAC systems for physical disabilities. Concerning mental disability, there are tools based on pictograms. This paper is divided into two parts. First, we put forward a critical review of various AAC systems with a focus on users with athetoid cerebral palsy. Second, the paper presents work in progress concerning a communication system for such users.
