The life is automatically recorded as images, audio and possibly video, and is organised along time, place, person and object dimensions. Each day is automatically divided into activities.

At the end of each day, the person with dementia and the carer (relative) reviews the activities of that day, and adds information about names of persons, places and objects etc. This caring activity also helps the person with dementia to build episodic memories of the day.

The person with dementia can navigate the past and future life using a mobile device, and can even ask for advice on what is the normal activity in that situation.
