This paper highlights the development of a computerized communication aid for intubated patients in an Intensive Care Unit (ICU). Intubated patients in ICU have few methods of communicating other than attempting to mouth words and use gestures. Communication aids that are available, such as symbol charts and alphabet boards, unfortunately have not been designed to meet the specific requirements of these patients. Even these methods are not ideal for the patient, their family members or the staff caring for the patient. From previous research studies of communication within ICU, patients often feel disempowered and depressed due their inability to contribute to conversations. This often leads to feelings of social isolation. ICU-Talk will be developed to allow the patient to have more control of their communications and at the same time address their ongoing problems and needs on an individual basis.
