Studies identifed good memory cues for people with episodic memory impairment (EMI) to aid the design of lifelogging technologies. A field study was conducted with 5 dyads of people with Alzheimer's disease and their caregivers, observing and interviewing participants for 2 full, consecutive days. Caregivers were found to use cues, or small details, to help the people with EMI recall past experiences. A second study was undertaken, using 5 individuals with EMI and their caregivers, and 4 unimpaired individuals over the age of 65. A card-sorting technique was employed with photos automatically taken by a wearable digital camera, SenseCam, during a personal experience to provide participants with a concrete way to identify good memory cues. Participants identified the main content of each photo, then sorted the photos providing the best memory cues for their experience during several elimination trials. Based on this process, 4 types of cues were identified: Person, Object, Place, and Action. Major criteria for cue selection identified were Recognizability, Distinctiveness, and Personal Significance. Participants with EMI were more likely than unimpaired participants to choose photos that represented the gist of their experience. Implications for further research are discussed.
