Outline

• Introduction

• AwareMirror System

• Evaluation

• Concluding Remarks

Introduction

• Due to the advancement of technologies computational devices and a heavy amount of information.

• A mirror has been utilized since ancient days. It reflects physical objects appearing in front of it.

AwareMirror System

• Overview

• Two Modes of Information Rendering

• Prototype Implementation

Overview

• Mirror displays information relevant to a person in front of it on the periphery of his/her sights.

• 3 types of low-level information– infra-red range– Personal (unshareable) information– personal artefact

• 3 types of information to display– Weather– state of a public transportation – next appointment

Two Modes of Information Rendering

• listed information is useful but might disturb a user's primary task.– image-based– text-based

Prototype Implementation

Evaluation

• Methodology

• Results and Discussions

Methodology

• A Wizard-of-Oz (WoZ) method.

• Fourteen subjects (12 students and 2 company employees)

• One family (parents and an adult daughter) and a company employee living alone.

Results and Discussions

• Activation of Abstract Information Mode– half of the subjects (7 people)

• Transition to Detailed Information Mode– 68.8% of the subjects (11 persons)

• Detailed Information Rendering– 68.8% of the subjects

• Two Phase Information Presentation– 66.7% of the subjects (10 persons)

Concluding Remarks

• Shows that the majority of the subjects preferred – the two-phase information provision.– the automatic activation and the manual transition.

• User likes an ordinary mirror at the beginning, but once has interests in the information, it should be useful as an information display.
