Lifelogging is the automatic capture of daily activities using environmental and wearable sensors such as MobilePhone/SenseCam. The potential to capture such a large data collection presents many challenges, including data analysis, visualisation and motivating users of different ages and technology experience to lifelog. In this paper, we present a new generation of lifelog system to support reminiscence through incorporating event segmentation and group sharing. © Springer-Verlag 2013.
