Human memory is a powerful tool, allowing us to remember past incidents, such as where we left our keys, or where we parked our car. All too often, however, we tend to forget things we have to do, or specific details of past events. This is emphasized in people that suffer from clinically diagnosed memory disorders such as Alzheimer disease, which impair episodic memories, drawing them away from their natural ability of recalling past experiences.
In this project, we aimed at understanding how and why different types of digital lifelogs support the recall and reflection of daily activities and experiences. We developed Footprint Tracker, a tool that augments streams of Lifelog images (i.e. visual cues) with geographic (i.e. location) and temporal (i.e. time) data, as well as social context (i.e. mobile and phone calls). Through a field study, we examined how these different types of cues trigger memories of recent events and associated emotions.
