    Augmented reality (AR) has the potential to create compelling learning experiences. However, there are few research works exploring the design and evaluation of AR for educational settings. In our research, we treat AR as ...
  • Ericson, Marc; Santos, Marc Ericson C.; Almeida, Igor de Souza; Yamamoto, Goshiro; Taketomi, Takafumi; Sandor, Christian; kato, Hirokazu (Springer Nature, 2015-10-05)
    Virtual objects can be visualized inside real objects using augmented reality (AR). This visualization is called AR X-ray because it gives the impression of seeing through the real object. In standard AR, virtual information ...
  • Krichenbauer, Max; Yamamoto, Goshiro; Taketomi, Takafumi; Sandor, Christian; Kato, Hirokazu (IEEE, 2018-02-01)
    Virtual Reality (VR) Head-Mounted Displays (HMDs) are on the verge of becoming commodity hardware available to the average user and feasible to use as a tool for 3D work. Some HMDs include front-facing cameras, enabling ...
  • Hyry, Jaakko; Krichenbauer, Max; Yamamoto, Goshiro; Taketomi, Takafumi; Sandor, Christian; Kato, Hirokazu; Pulli, Petri (2017-04-01)
    Projector-camera (ProCam) systems have a potential to become popular and affordable as they can create interactive surfaces for example on tabletops, walls, household items or on a palm of a hand. The possibility that these ...
  • Taketomi, Takafumi; Uchiyama, Hideaki; Ikeda, Sei (Springer Open, 2017-06-02)
    SLAM is an abbreviation for simultaneous localization and mapping, which is a technique for estimating sensor motion and reconstructing structure in an unknown environment. Especially, Simultaneous Localization and Mapping ...
  • Zeeshan, Asghar; Niina, Keranen; 山本, 豪志朗; 武富, 貴史; Christian, Sandor; 加藤, 博一; Petri, Pulli (EAI Endorsed Transactions, 2017-09-07)
    We present a design and preliminary evaluation of novel visual guidance of a remote assistive system for the elderly to find hidden objects in a kitchen. Our system has two essential functions; 1) to update a list and ...
  • Damien Constantine, Rompapas; Aitor, Rovira; Alexander, Plopski; Christian, Sandor; 武富, 貴史; 山本, 豪志朗; 加藤, 博一; Ikeda, Sei (2017-09-18)
    Augmented Reality (AR) superimposes computer graphics (CG) onto a user’s view of the real world. A key quality problem in this field is to achieve coherence between reality and CG when the user’s eyes refocus or change ...
  • YAMAMOTO, Goshiro; SAMPAIO, Luiz; TAKETOMI, Takafumi; SANDOR, Christian; KATO, Hirokazu; KURODA, Tomohiro (The Institute of Electronics, Information and Communication Engineers, 2017-09-01)
    We present a novel method to enable users to experience mobile interaction with digital content on external displays by embedding markers imperceptibly on the screen. Our method consists of two parts: marker embedding on ...
  • Yamamoto, Goshiro; Taketomi, Takafumi; Sandor, Christian; Kato, Hirokazu; Feiner, Steven (Elsevier, 2017-06-01)
    With the ongoing introduction of wide-FOV VR head-worn displays into the consumer market, the application of VR 3D UIs to professional work environments is attracting increasing attention. One of the most conspicuous ...
  • Kato, Hirokazu; Muyazaki, Jin (Springer Nature, 2008-01-01)
    Previously, we proposed two recommendation systems—context-aware information filtering (C-IF) and context-aware collaborative filtering (C-CF)—both of which are context-aware recommendation methods. We have also shown their ...
  • Kato, Hirokazu; Sandor, Christian; Yamamoto, Goshiro; Taketomi, Takafumi (IEEE, 2015-09-23)
    Usability evaluations are important to improving handheld augmented reality (HAR) systems. However, no standard questionnaire considers perceptual and ergonomic issues found in HAR. The authors performed a systematic ...
  • Long, Qian; Alexander, Plopski; Nassir, Navab; Peter, Kazanzides (IEEE, 2018-09-06)
    Recent technical advancements support the application of Optical See-Through Head-Mounted Displays (OST-HMDs) in critical situations like navigation and manufacturing. However, while the form-factor of an OST-HMD occupies ...
  • 角田, 雅照; 秋永, 知宏; 引地, 一将; 大杉, 直樹; 柿元, 健; 門田, 暁人; 松本, 健一 (教育システム情報学会, 2010)
    It is important for software engineers to improve their skills by self-learning existing software development techniques. However, it is not easy for engineers to find out which techniques should be learned because there ...
  • Nakamura, Ko; Hayashi, Yu-ichi; Mizuki, Takaaki; Sone, Hideki (IEEE, 2017-11-28)
    In this paper, we present a new information leakage threat combining intentional electromagnetic interference (IEMI) and observations of EM leakage. In previous studies, the analysis of secret key information in cryptographic ...
  • MITANI, YOSHIKI; YOSHIKAWA, HIROYUKI; TSURUHO, SEISHIRO; MONDEN, AKITO; BARKER, MIKE; MATSUMOTO, KEN-ICHI (World Scientific Publishing Co., 2011-05-11)
