Prompting devices: a survey of memory aids for task sequencing

Abstract

People with mild to medium cognitive impairments may have difficulty with remembering when to perform an activity of daily living (ADL). For people with more severe cognitive impairments, it can be difficult to learn and/or recall the sequence of steps needed to complete a task. In this paper, we present a survey of devices that provide step-by-step detail of ADL tasks with picture, text, audio, video, and/or vibration prompts. We provide a description of each device's overall capabilities, an analysis of contextual awareness and automatic plan adaptation, and end-user evaluation.
