Reminding technology for prospective memory disability: a case study.

Congenital or acquired brain damage resulting in prospective memory loss can make a child unable to become independent of care givers. This note describes a memory aid developed for a 17 year old with spina bifida and hydrocephalus who requires continual reminding to perform health maintenance tasks such as medication and feeding. Off-the-shelf computer hardware and software were used to make a reminding system that logged task completion information. Logging is a unique feature of this system, permitting review of the user's response to reminders for health or rehabilitative purposes. The system reduced the need to remind rate from > 75% to less than 10% of the time. Reminding rates returned to > 75% upon removal of the system. With the system this adolescent achieved more independent health maintenance. Weight and power requirements make this system embodiment impractical for general wheelchair use, but the technology in currently available pocket units may support the necessary functions.
