Yukiya Mita (M1), Hiroaki Murakami, Takuya Sasatani and Yoshihiro Kawahara, who belong to the Department of Electrical Engineering and Information Systems, received the Best Paper award 1st Place at the International Conference on Indoor Positioning and Indoor Navigation (IPIN) 2024.

Name of award and short explanation about the award

We received the Best Paper award 1st Place out of 78 accepted papers at the International Conference on Indoor Positioning and Indoor Navigation (IPIN) 2024 held from October 14 to October 17, 2024.

About awarded research(activity)

In indoor spaces where GPS is not available, positioning technologies using radio waves (Wi-Fi, BLE) and sound waves are the mainstream. Positioning methods using location fingerprints are particularly suitable for indoor environments where direct wave reception is difficult due to building structures and fixtures. However, these technologies suffer from low positioning accuracy. In this study, we utilized the Time-of-Flight information of multiple reflection waves, unique to indoor spaces, as location fingerprints. We combined extensive pre-training using acoustic simulation with fine-tuning based on measurement data, enabling high-accuracy positioning with a small amount of measurement data.

Your impression & future plan

I am honored to receive this prestigious award. I would like to express my deepest gratitude to everyone in my laboratory who has supported me over the years. We will continue to improve our positioning system to enhance its positioning performance and to make it more versatile through positioning experiments in a variety of environments.
