Wearable Interfaces for a Video Diary: towards Memory Retrieval, Exchange, and Transportation

In this paper, we discuss wearable interfaces for a computational memory-aid useful in everyday life. The aim of this study is to develop a Video Diary system with vision interfaces to aid in memory retrieval. The Video Diary system provides users with “Memory Retrieval, Exchange, and Transportation ” through four types of indexes: 1) through the user’s location, 2) through real world object(s), 3) through keyword(s) and 4) through the use of a summary or “the story of the day. ” The authors have developed the following two systems to achieve the above indexes: 1) a Residual Memory system, 2) a Ubiquitous Memories system. Residual Memory can index a user’s location automatically by analyzing a video recorded from a wearable camera for “Memory Retrieval. ” Ubiquitous Memories provides users with the ability to associate augmented memories with real world objects for “Memory Exchange. ” We have integrated the above two systems for “Memory Transportation. ” We believe that the above interfaces can be integrated into the Video Diary system.
