    Enrichment of TV Series With Augmented and Mixed Reality Applications on Mobile Devices and on HoloLens
    (The Eurographics Association, 2018) Strzebkowski, R.; Gehrmann, T.; Wulf, D.; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    In this demo we will present two related AR/MR projects realized in cooperation with the German public broadcaster ZDF, which consist of an interactive mobile 3D Augmented Reality infotainment/game application as well as a Mixed Reality version of the infotainment app for HoloLens. The aim of the projects was to evaluate the technical, gamification and infotainment potentials for so-called companion apps based on AR/MR technologies for the very successful TV series 'Die Bergretter' (The Mountain Rescuer). Both applications provide rich interactivity with story connectivity to the TV series and give seldom experience of similar content at mobile and HoloLens devices.

    Study of Human Behavioral Characteristics: Using Virtual Reality to Analyze Behavior of Following Moving Objects
    (The Eurographics Association, 2018) Yonezawa, Kazuya; Segawa, Eigo; Tanaka, Ryuta; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    It is crucial to model the physical world for simulation in which various phenomena are represented on a computer. In the case of simulation involving human actions, it is necessary to model not only physical phenomena but also human behaviors. However, there are still many unclear things about human behaviors. In this study, to clarify these behavioral characteristics, we verified two hypotheses using virtual reality. One was that ''people follow moving objects similar to humans in shape,'' and the other was that ''people follow the route with the majority of other objects.'' We tested these hypotheses by conducting two experiments allowing participants to select a route in a virtual maze in which objects were moving under certain rules. The results showed that people tend to follow moving objects regardless of their appearances, and also tend to follow the majority.

    User Evaluation of Visuo-Haptic Collocation System
    (The Eurographics Association, 2018) Cha, B.; Bae, Y.; Choi, W.; Ryu, J.; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    In the encounter-type haptic display systems, visuo-haptic collocation is essential because a poorly collocated pair of virtual and real objects may hinder natural interaction. This poster presents user evaluation results of a visuo-haptic collocation system. By measuring performances of two tasks for pressing a button and grasping a steering wheel, the developed visuohaptic collocation system can provide users with natural interaction experiences.

    Virtual Agent System to Induce Reminiscence Utterances With the Past and Present Map Information
    (The Eurographics Association, 2018) Takase, Yutaka; Nakano, Yukiko I.; Yasuda, Kiyoshi; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    In recent decades, the increasing number of elderly people with dementia has become a major social problem. Under such circumstances, virtual agent systems aimed at helping with mental health care for the elderly have attracted increasing attention. In this study, we propose a novel virtual agent system that encourages users' speaking about their reminiscences of their hometown or favorite places. The key idea is that the contents that the agent delivers (i.e., speaks) are generated automatically depending on the present and past information about the places in question.

    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.

    Visuo-Haptic Redirected Walking Using Handrail
    (The Eurographics Association, 2018) Matsumoto, Keigo; Narumi, Takuji; Yanase, Yohei; Ban, Yuki; Tanikawa, Tomohiro; Hirose, Michitaka; Huang, Tony and Otsuki, Mai and Servières, Myriam and Dey, Arindam and Sugiura, Yuta and Banakou, Domna and Michael-Grigoriou, Despina
    A novel use of virtual reality (VR) was demonstrated. It enables a user to feel walking a straight virtual corridor while touching straight handrails, although the user walks while gripping circular handrails within a limited space. The main contribution of this study is to show that visual-haptic redirect walking is possible using handrails for a haptic presentation. Matsumoto et al. introduced visuo-haptic redirected walking. They used walls as a haptic presentation, and they produced Unlimited Corridor as a VR demonstration using visuo-haptic redirected walking. However, it has not yet been verified whether the same effect can occur by touching other shapes. Therefore, in this study, a VR demonstration using handrails instead of walls was created, and whether visuo-haptic redirected walking is possible even with handrails for haptic presentation was examined. In the demonstration, more than 2000 people participated, and their comments and motion data were gathered. The users' comments implied that visuo-haptic redirected walking was possible using handrails.
