Early Experiences of Visual Memory Prosthesis for Supporting Episodic Memory

This article describes the use, experiences, and inferred design issues of an audio-visual content recorder that supports retrospective episodic memory (i.e., memory of personal events). In addition, some further user interface issues are discussed. The concept was explored by collecting mostly images and some audio over a period of more than a year (every now and then) using a body-worn camera and DAT-recorder. Special browser was built to be used in wearable and desktop computers. We also consider the use of thumbnail reductions of images. We empirically determined that image and audio data could help episodic memory to recall other facts related to the recorded episode. This kind of technology could be utilized in both personal and professional applications.

Context triggered visual episodic memory prosthesis

This paper briefly describes a context sensitive recorder and replay system that supports retrospective episodic memory. The concept has been explored by implementing a prototype system, which utilizes simple context information based on infrared beacons to store and retrieve images taken with a wearable camera. Presenting visual content about a users life, in mobile use, should help memory to recall other facts about the users context.

Using Wearable Computer as an Audiovisual Memory Prosthesis

This paper describes briefly the use of a futuristic audiovisual content recorder that supports retrospective episodic memory. The concept was explored by implementing a wearable prototype system, which was used to collect image and audio material over a period of several months. It was confirmed in this wearable computer context that image and audio data could help episodic memory to recall other facts related to that episode. This kind of technology could be useful in both working life as well as in free time.
