Functional evaluation of a vision-based object remembrance support system

People tend to forget where they placed an object, which is needed to achieve a certain task, in their everyday circumstances. To support a user's object-finding tasks, we have proposed a wearable interface system named "I'm Here!". The system manages Augmented Memories, a video database of the user's viewpoint labeled with previously registered objects, to display the last video of the target object held by the user. We evaluate the function of the system with laboratory experiments, and discuss the positive and negative effect of the system with the experimental results.
