Memory deficit is one of the most frequent cognitive complications encountered after brain injury. It is recognized as difficult to treat. Over the past decades, various strategies of memory remediation have been used. Among them, prosthetic devices, such as notebooks and alarms, have shown some benefit. This study describes the case of a 22-year-old man who demonstrated deficits in memory and executive function. In an in-patient rehabilitation setting, a microcomputer was introduced as an external memory aid. With this intervention, the patient demonstrated an immediate improvement in the ability to attend every therapy and ask for every medication on his schedule. This case study demonstrates the usefulness of a microcomputer as an external memory aid for a memory-impaired head injury survivor.

In comparison to all types of injury, those to the brain are among the most likely to result in death or permanent disability. A certain percentage of these brain-injured people cannot communicate, recreate, or control their environment due to severe motor impairment. This group of individuals with severe head injury has received little from assistive technology. Brain computer interfaces have opened up a spectrum of assistive technologies, which are particularly appropriate for people with traumatic brain-injury, especially those who suffer from "locked-in" syndrome. Previous research in this area developed brain body interfaces so that this group of brain-injured people can communicate, recreate and launch applications communicate using computers despite the severity of their brain injury, except for visually impaired and comatose participants. This paper reports on an exploratory investigation carried out with visually impaired using facial muscles or electromyography (EMG) to communicate using brain body interfaces.

Multimedia has been used creatively to entertain and educate, and can also be used for therapeutic and medical purposes. This paper addressed this issue by incorporating multimedia to design and develop an assistive device to help disabled children with speech impairments in mainstream education. The appropriate methodology for developing such an interface was investigated. Relevant multimedia, psychology, social and educational theories were taken into account. Based on this literature review, interfaces to enhance pronunciation were designed, developed and tested.
