Lifelog means using wearable devices to record human’s life automatically which can help users recall. More and more lifelog cameras with multiple sensors become available to the public. To view the vast amount of lifelog photos captured by the devices, the manufacturers provide supporting viewer systems. However, current systems only enable users to view the photos in time order by installing the specialized software. Previous research stated that memories can be recalled by memory cues, such as where the event happened, who was involved. In this research, we intend to find out the most important memory cues that help people recall and create a new lifelog viewer system to help users recall past more efficiently without increase the burden on users. To find out which cues appear more in events remembered by people, we conducted several experiments. The proposed new lifelog viewer system can recognize object, location, face and time information in lifelog photos automatically and show photos according to these memory cues information instead of in time order. With the system, users can retrieve photos of past events via these multiple memory cues. We also conducted a preliminary user study to evaluate, the results show the validity of the proposed system.
