An Audio-Based Personal Memory Aid

摘要

We are developing a wearable device that attempts to alleviate some everyday memory problems. The "memory prosthesis" records audio and contextual information from conversations and provides a suite of retrieval tools (on both the wearable and a personal computer) to help users access forgotten memories in a timely fashion. This paper describes the wearable device, the personal-computer-based retrieval tool, and their supporting technologies. Anecdotal observations based on real-world use and quantitative results based on a controlled memory-retrieval task are reported. Finally, some social, legal, and design challenges of ubiquitous recording and remembering via a personal audio archive are discussed.
