The practice of lifelogging potentially consists of automatically capturing and storing a digital record of every piece of information that a person (lifelogger) encounters in their daily experiences. Lifelogging has become an increasingly popular area of research in recent years. Most current lifeloggiing research focuses on techniques for data capture or processing. Current applications of lifelogging technology are usually driven by new technology inventions, creative ideas of researchers, or the special needs of a particular user group, e.g. individuals with memory impairment. To the best of our knowledge, little work has explored potential lifelogs applications from the perspective of the desires of the general public. One of the difficulties of carrying out such a study is the balancing of the information given to the subject regarding lifelog technology to enable them to generate realistic ideas without limiting or directing their imaginations by providing too much specific information. We report a study in which we take a progressive approach where we introduce lifelogging in three stages, and collect the ideas and opinions of a volunteer group of general public participants on techniques for lifelog capture, and applications and functionality.
