苗村研究室オープンハウス2023 レポートNaemura Lab Open House 2023 Report




本年度のオープンハウスでは、バーチャルリアリティ(Virtual Reality; VR)関連技術の展示が4件と、例年に比べて多かったことが特徴的でした。周辺視野のコントラストを低減してVR酔いを軽減する手法、視野の解像度を制御することでVRHMDユーザの視線を誘導する手法、バーチャル環境でユーザが表出する非言語情報をもとに嘘を判別する技術など、次世代のコミュニケーションプラットフォームであるメタバースを意識した研究が見受けられました。こうした研究の他にも、東京大学本郷テックガレージや東京大学インクルーシブ工学連携研究機構(RIISE)の価値交換工学、中山未来ファクトリーでの活動紹介もブースとして展開されていました。



The Naemura Laboratory held its annual Open House on February 28th, 2023, at the Engineering Building No. 2, Hongo Campus, with its members showcasing their latest research projects. The event featured 20 posters and demonstrations presented by students and faculty members, spread across two rooms. This is the first offline and publicly accessible event in four years since 2019.

The Naemura Laboratory conducts fundamental technology research in physical control (optical design and circuit implementation), information processing (machine learning and signal processing), and interaction design (action induction and emotion arousal), as well as applied research that extends these to mixed reality, image recognition, entertainment computing, and multi-user harmonized information environments.

For instance, their research on extending and supporting online communication involved developing tools that enable users to effortlessly switch between multi-party and individual conversations in online voice communication, which has gained wide acceptance due to COVID-19. Other research also supported the expression of emotions using fonts in subtitling and text chat. Furthermore, research on light and aerial images, a well-known theme of the Naemura Lab Open House, is ongoing. They exhibited the technology for high-contrast data embedding in visible light communication projectors and communication between display and camera using color vibration markers.

This year’s Open House featured a greater number of exhibits related to Virtual Reality (VR) technologies than in previous years. Research with an awareness of the next-generation communication platform, the metaverse, was showcased. Their research includes a method to reduce VR sickness by reducing the contrast of peripheral vision, a method to guide the VRHMD user’s gaze by controlling the resolution of the field of vision, and a technology to identify lies based on non-verbal information expressed by the user in a virtual environment.

In addition to these projects, there were other booths showcasing activities: the Hongo Tech Garage at the University of Tokyo, Value Exchange Engineering at the Research Institute for Inclusive Engineering Collaboration (RIISE) at the University of Tokyo, and the Nakayama Future Factory.

It has been a long time since an open house was held on-site, and many students may not have had the opportunity to exhibit their posters face-to-face. Professor Naemura expressed his gratitude for successfully holding the Open House despite the circumstances. During the event, all demonstrations ran smoothly, and presenters engaged in in-depth discussions about their research. The Open House in the 2023 academic year is highly anticipated.
