  In this paper, we investigate the effectiveness of two distinct techniques
(Special Moment Approach & Spatial Frequency Approach) for reviewing the
lifelogs, which were collected by lifeloggers who were willing to use a
wearable camera and a bracelet simultaneously for two days. Generally, Special
moment approach is a technique for extracting episodic events and Spatial
frequency approach is a technique for associating visual with temporal and
location information, especially heat map is applied as the spatial data for
expressing frequency awareness. Based on that, the participants were asked to
fill in two post-study questionnaires for evaluating the effectiveness of those
two techniques and their combination. The preliminary result showed the
positive potential of exploring individual lifelogs using our approaches.
