Emotional tagging with lifelog photos by sharing different levels of autobiographical narratives

Abstract

The lifelogging camera continuously captures one’s surroundings, therefore lifelog photos can form a medium by which to sketch out and share one’s autobiographical memory with others. Frequently, the lifelog photos do not provide the context or significance of the situations to those not present when the photos were taken. This paper solicits the social value of the lifelog photos by proposing different levels of autobiographical narratives within Panofsky’s framework. By measuring the narrative engagement with questionnaire and the activation level of the lateral prefrontal cortex (LPFC), we have found that delivery the autobiographical narrative at the iconological level triggers the receiver’s empathetic response and emotional tagging of the sharer’s lifelog photos.
