Abstract
The external compensatory means recommended for rehabilitation of memory disorder must consist of a means for storing information externally and a clue for accessing the externally stored information. Writing down the information on a paper pocketbook is usually used as an external compensatory means, but smartphones are overwhelmingly more useful in terms of the functions as compared to paper pocketbooks. The author, who has a memory disorder and works as an occupational therapist, has recently devised a method for utilizing a smartphone for overcoming the inconveniences during daily living and herein describes how to use it in daily life scenarios.
