The purpose of this article is to describe the impact of an intervention involving safe-laser pointing technology on six persons with locked-in syndrome. When these individuals were invited to participate in this project (4 weeks to 18 years post onset), none were able to speak and none were able to access an augmentative and alternative communication (AAC) device. All communicated using eye movements (e.g., looking up or down), eye blinks, dependent scanning strategies with eye movement… Expand
Design and development of a rehabilitative eye-tracking based home automation system
Locked-in syndrome is known to be a condition in which a patient loses the ability to control nearly all voluntary muscles in the body except for the eye. In today's world, healthcare facilities haveExpand
Communication Matters—Pitfalls and Promise of Hightech Communication Devices in Palliative Care of Severely Physically Disabled Patients With Amyotrophic Lateral Sclerosis
High-tech augmentative and alternative communication (HT-AAC) technologies provide the possibility to maintain caregiver-independent communication and environmental control even in the advanced disease state of ALS, and their use is reported to strengthen self-determination, increase patients' quality of life and reduce caregiver burden.

Review on Locked-in Syndrome
Health care providers and insurers can be helped to prepare for the expense of treating these seriously impaired patients in the long term by a greater understanding of the outcome for LIS patients, and health care providers need to identify the value of factual diagnosis for the treatment of development plans.

Promoting Engagement, Requests and Choice by a Man with Post-Coma Pervasive Motor Impairment and Minimally Conscious State through a Technology-Based Program
We assessed a program to promote constructive engagement, requests, and choice by a man with post-coma pervasive motor impairment and minimally conscious state. The program was based on learningExpand
A speller system for locked-in patient to communicate with friends
The proposed speller system is suitable for those LIS patient with head movement ability, it could help them to communicate with friends and is easy to implement because it only requires a laptop which contains digital camera. Expand
Peripheral Autonomic Signals as Access Pathways for Individuals with Severe Disabilities: A Literature Appraisal
Many individuals with severe and multiple disabilities do not have an access pathway that enables them to interface with their environment because they are not afforded a binary switch that they canExpand
Access Interface Strategies
The state of the science of access technologies that interface with augmentative and alternative communication devices are reviewed and a future research and development agenda is proposed that will enhance access options for people with limited movement capability due to developmental and acquired conditions is proposed.

Augmentative and alternative communication methods in locked-in syndrome.
The multidisciplinary rehabilitation team developed an individual alternative communication method for all patients and trained them to use it by minor movements of e.g. thumb, chin or head and enabled most of the patients to interact with other people using practical as well as theoretical thinking and decision making.

It is postulate that the "locked-in" state cannot only be reversible, but it may also recur as the result of multiple episodes of transient vertebrobasilar ischemia. Expand
