Human memories are often not grouped around objective times and places but rather guided by subjective perception of these dimensions. Various techniques are used to recall personal information such as remembering names, conferences and numbers, but how different experiences or events or the event that has taken place two years earlier raises a question. Occasionally, having experienced an event, one may be asked about its absolute time in autobiographical memory. It is surprisingly difficult to predict the time when this date needs to be remembered. There is a tendency to use partial temporal information such as birthdays, parties or seasons to remember, rather than a specific date e.g. 21 September 1996. People need appropriate facts or personal semantics of their time to access to their past experiences while remembering. A user study was conducted to explore the use of past personal temporal information and capture this information to be used as personal time search features in an augmented memory system called Digital Parrot. These features aim to make temporal dates more easily accessible while remembering. A proposed design was made according to requirements that are derived from findings of psychology perspective, an exploration of the use of time study, and the visualizing time study. To evaluate how effective these features in locating and recalling past experiences, a user study was conducted with post questionnaires. The result of this study indicated that the most beneficial personal time search features are personal timespans, personal and public landmarks, and personal images. The findings from all studies of the thesis were used to provide recommendations for future work to develop and implement personal time search in Digital Parrot system.
