Review of assistive technologies for disabled people (original) (raw)
2017, Biomedical engineering
Introduction. Disabilities significantly affect the quality of life of patients as well as their relatives. Additionally, patients require some form of care that is both time consuming and expensive. Making patients more independent can therefore improve their quality of live as well as reducing the need for care services. Assistive technologies are a very broad field covering a range of assistive, adaptive and rehabilitative devices that increase people independence by enabling them to perform tasks that they were formerly unable to accomplish. This paper discusses assistive technologies for people with severe mobility disabilities such as tetraplegia or paraplegia. In particular, we will review the state of the art assistive technologies for human computer interaction (HCI). This paper mainly focuses on three aspects of HCI, namely user input modalities, user interface (UI) and information presentation modalities. These three components are crucial in creating modern HCI that will enable disabled people to perform challenging tasks. An overview of the topics that will be discussed in this paper can be seen in Fig. 1. This paper reviews the state of the art assistive technologies. Three topics are covered in the paper, namely user input modalities, user interface and information presentation modalities. The main focus of the paper is assistive technologies for patients with severe mobility disabilities such as tetraplegia or paraplegia. The system architecture and implementation details of a modular human computer interface are also provided. This system can easily be adapted according to the abilities of a particular patient.
