A systematic review, which brings empiric evidence about the potential utility of portable cameras based on lifelogging to improve autobiographical memory, has been published recently. This study is based on the analysis of the results of 20 different studies that have used this device with different groups (healthy youths, people with severe memory problems due to brain damage, people with mild cognitive impairment) to compare if the use of such device improved their autobiographical memory.

The conclusion of this study is that the review of personal episodes from the own images recorded (i. e. from a first person point of view) improves the recall of that information. The results suggest that the display of experienced episodes strengthens encoding information and activates a series of cognitive and emotional reactions that facilitate the direct retrieval of the episode.

The study also evidences some limitations of the studies executed so far, such as small sample sizes and case study designs. For this reason, they highlight the need of new studies with bigger samples so the results can be methodologically more rigorous. Finally, they also take into account the ethical issues derived from the use of this new technology.
