    Effect of an Encounter-Type Haptic Device on Forceps Position Reproducibility in Laparoscopic Tracking Training
    (The Eurographics Association, 2018) Morishima, Akinobu; Terashima, Akihiro; Obama, Kazutaka; Sakai, Yoshiharu; Maeda, Taro; Ando, Hideyuki; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    This paper describes an improvement to our previously proposed laparoscopic training system that was designed to improve surgical skill transmission by allowing surgical trainees to replicate the movements of skilled surgeons dis-played on a monitor. However, we found that with this system, the precision of followability in the depth direction was low in comparison with that on the monitor in the planar direction. Herein, to improve the reproducibility of the forceps position and present clues for depth perception, we provide learners with haptic feedback by reproducing the viscera wall using an encounter-type haptic presentation device.

    Laparoscopic Sigmoidectomy Surgery Training System Using AR Follow-up Experience of Real Human Surgery
    (The Eurographics Association, 2018) Terashima, Akihiro; Morishima, Akinobu; Obama, Kazutaka; Sakai, Yoshiharu; Maeda, Taro; Ando, Hideyuki; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    In our learning system (OITORE Advance), high learning effect was confirmed by using teaching materials using porcine intestines. However, because the environment inside the abdominal cavity is different between pigs and people, there are scenes with different surgical procedures and surgical skills. Therefore, not all the learned skills are applied in human surgery. Therefore, in this paper we changed teaching materials from pig to human and adjusted the system accordingly.

    Natural Interface and Overreaction for VR Entertainment
    (The Eurographics Association, 2018) Kawamoto, T.; Horikoshi, T.; Liberati, N.; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    With the widespread use of inexpensive VR devices, many VR events for entertainment started to be organized all over the world. An important point when many people experience VR content is easily engage the experience without losing too much time to understand how the interaction between users and virtual world is designed. Thus, it is very important to think of simple and intuitive interfaces. We aimed for a more intuitive interaction, and we replaced the hand controller with the CG models of hands by Leap Motion. In this demonstration, we can highlight the difference in interacting through hand controllers and directly without the intrusion of any tangible device.

    VirtualCar: Virtual Mirroring of IoT-Enabled Avacars in AR, VR and Desktop Applications
    (The Eurographics Association, 2018) Pappas, G.; Siegel, J.; Politopoulos, K.; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    This demo features a virtual 3D car model based off a vehicle's data duplicate, an IoT-enabled Avacar. There are three embodiments including a desktop application (VirtualCar), Augmented Reality (VirtualCarAR), and Virtual Reality (VirtualCarVR). The Avacar gets information from an external API serving information from a real or rep-resentative simulated vehicle, mirroring the sensors present in modern On-Board Diagnostic systems and the loca-tion data provided by a mobile device's GPS. In each application, the Avacar appears at specific locations around the world, using the Unity Game Engine to virtually mirror the behavior of the actual or simulated vehicle in real-time.
