How to design an electronic memory aid for brain‐injured patients: Considerations on the basis of a model of prospective memory

Abstract

There has been an enormous development in the field of electronic memory aids, such as mobile phones, organizers, or combinations of both. Nevertheless, these devices have hardly been useful in the neuropsychological therapy of memory‐impaired patients so far. The model of prospective remembering by Ellis (1996) is used as theoretical background in order to (1) analyse patients' needs concerning electronic memory aids, (2) evaluate the usefulness of electronic memory aids for patients described in the literature, as well as of two commercially available electronic memory aids, and (3) derive conclusions concerning demands on how to design a memory aid suitable for patients. While most of the devices designed for patients improve their reliability by compensating for lack of self‐initiated retrieval, most of them are not able to compensate for problems during execution or evaluation. Commercially available memory devices have the advantage of being available to everybody, but they can only support mildly impaired patients. Patients with more severe deficits, however, need a more suitable interface in order to facilitate data entry. In addition, interactive chains of actions should be implemented in order to support execution and evaluation of future intentions. MEMOS, a system in development that tries to realize these demands, is presented.
