Abstract

Lifelogging technologies promise to help support total recall of our lives through automated capture of large volumes of digital content. However, research has shown that lifelogging brings less benefit for memory than anticipated. To address this we report a diary study with 12 participants provided with tools for capturing cues through photos, doodles, moods, diaries, audio, and video recordings to support recall of their meaningful daily events. Findings indicate that cues capture both external and internal content for both recall and reflection, and the different impact of cues’ content and modalities: people and objects captured through photo, or audio/video of environment support better recall of environment context, while feelings were better recalled by doodle, emoticon, diary or audio/video of one’s voice. We conclude with three design implications for materializing both external and internal cues and the active construction of the latter, new interfaces for more meaningful spatio-temporal cues, and for integrating the various multimodal cues’ content.
