Item 3D Ground Reaction Force Visualization onto Training Video for Sprint Training Support System(The Eurographics Association, 2017) Taketomi, Takafumi; Yoshitake, Yasuhide; Yamamoto, Goshiro; Sandor, Christian; Kato, Hirokazu; Tony Huang and Arindam DeyWe propose a method for visualizing 3D ground reaction forces for sprint training. Currently, sprinters can check their 3D ground force data using a 2D graph representation. In order to check the relationship between 3D ground force and their sprint form, they must check the 2D graph and a training video repeatedly. To allow simultaneous observation of the 2D graph and the training video, we use a mixed reality technology to overlay 3D ground reaction force onto the training video. In this study, we focus on 2D-3D registration between the image sequence and 3D ground reaction data. We achieved 2D-3D registration by using a constrained bundle adjustment approach. In the experiment, we apply our method to the training videos. The results confirm that our method can correctly overly 3D ground reaction force onto the videos.Item An Adaptive AR Tutor For Cabling a Network Topology(The Eurographics Association, 2017) Herbert, B. M.; Weerasinghe, A.; Ens, Barrett; Billinghurst, Mark; Tony Huang and Arindam DeyWe present an Augmented Reality (AR) network cabling tutor that provides visual annotations for improving learning in psychomotor tasks. Unlike many existing AR learning systems, our system combines AR with an intelligent tutoring system (ITS) that should enhance learning over existing desktop solutions. We intend to use this prototype as a test-bed for evaluating learning differences between a desktop web-based user interface, a hand-held AR display and a Head Mounted Display (HMD) AR display.Item An AR Network Cabling Tutoring System for Wiring a Rack(The Eurographics Association, 2017) Herbert, B. M.; Weerasinghe, A.; Ens, Barrett; Billinghurst, Mark; Wigley, G.; Tony Huang and Arindam DeyWe present a network cabling tutoring system that guides learners through cabling a network topology by overlaying virtual icons and arrows on the ports. The system determines the network state by parsing switch output and does not depend on network protocols being functional. A server provides a web-based user interface and communicates with an external intelligent tutoring system called The Generalized Intelligent Framework for Tutoring. Users use a tablet to view AR annotations, though support for HoloLens HMD will be added soon.Item Comparative Evaluation of Sensor Devices for Micro-Gestures(The Eurographics Association, 2017) Simmons, H.; Devi, R.; Ens, Barrett; Billinghurst, Mark; Tony Huang and Arindam DeyThis paper presents a comparative evaluation of two hand gesture recognition sensors and their ability to detect small, sub millimeter movement. We explore the capabilities of these devices by testing if users can reliably use the sensors to select a simple user interface element in 1D space using three distinct gestures a small movement of the thumb and forefinger representing a slider, the slightly larger movement of moving a finger up and down and a large gesture of moving the whole hand up and down. Results of our preliminary study reveal that the palm provides the fastest and most reliable input. While not conclusive, data from our initial study indicates that the Leap sensor provides lower error, difficulty and fatigue than the Soli sensor with our test gesture set.Item Comparative Evaluation of Sensor Devices for Micro-Gestures(The Eurographics Association, 2017) Simmons, H.; Devi, R.; Ens, Barrett; Billinghurst, Mark; Tony Huang and Arindam DeyThis paper presents a comparative evaluation of two gesture recognition sensors and their ability to detect small, movements known as micro-gestures. In this work we explore the capabilities of these devices by testing if users can reliably use the sensors to select a target using a simple 1D user interface element. We implemented three distinct gestures, including a large gesture of moving the whole hand up and down; a smaller gesture of moving a finger up and down and; and a small movement of the thumb against the forefinger to represent a virtual slider. Demo participants will be able to experience these three gestures with to sensing devices, a Leap Motion and Google Soli.Item Estimation of 3D Finger Postures with wearable device measuring Skin Deformation on Back of Hand(The Eurographics Association, 2017) Kuno, Wakaba; Sugiura, Yuta; Asano, Nao; Kawai, Wataru; Sugimoto, Maki; Tony Huang and Arindam DeyWe propose a method for reconstructing hand posture by measuring the deformation of the back of the hand with a wearable device. Our method constructs a regression model by using the data on hand posture captured by a depth camera and data on the skin deformation of the back of the hand captured by several photo-reflective sensors attached to the wearable device. By using this regression model, the posture of the hand is reconstructed from the data of the photo-reflective sensors in real-time. The posture of fingers can be estimated without hindering the natural movement of the fingers since the deformation of the back of the hand is measured without directly measuring the position of the fingers. In our demonstration, users can reflect his / her own finger posture in a virtual environment.Item Holo Worlds Infinite: Procedural Spatial Aware AR Content(The Eurographics Association, 2017) Lawrence, Louise M.; Hart, Jonathon Derek; Billinghurst, Mark; Tony Huang and Arindam DeyWe developed an Augmented Reality (AR) application that procedurally generates content which is programmatically placed on the floor. It uses its awareness of its spatial surroundings to generate and place virtual content. We created a prototype that can be used as the basis of a city simulation game that can be played on the floor of any room space, but the approach could also be used for many other applications.Item Holo Worlds Infinite: Procedural Spatial Aware AR Content(The Eurographics Association, 2017) Lawrence, Louise M.; Hart, Jonathon Derek; Billinghurst, Mark; Tony Huang and Arindam DeyWe developed an Augmented Reality (AR) application that procedurally generates content which is programmatically placed on the floor.

Therefore, we analyzed the effect of three monoscopic illusions, which are inspired by visual arts, i. e., (i) color temperature, (ii) luminance contrast and (iii) blur. The results provide positive indications that computer-generated projected illusions can influence the human depth perception in such an environment, even in the presence of additional conflicting depth cues.Item A Projection-Based Augmented Reality Setup for Blended Museum Experiences(The Eurographics Association, 2017) Schmidt, S.; Steinicke, F.; Tony Huang and Arindam DeyMost traditional museums still rely on physical artifacts since their authenticity and uniqueness foster an emotional engagement with the objects themselves and the stories they are supposed to tell the visitor. However, the context of the exhibition space makes it difficult to vividly present information that are closely related to the origin of the artifact. In this regard, we propose a 3D projection-based augmented reality setup, which keeps the focus on a physical exhibit and at the same time allows visitors to seamlessly switch to virtual representations of the exhibit's original appearance and context.Item Social Dining Experience using Mixed Reality for Older Adults(The Eurographics Association, 2017) Hart, Jonathon Derek; Lee, Gun A.; Smith, Ashleigh E.; Hull, Melissa; Haren, Matthew T.; Paquet, Catherine; Hill, Julie-Ann; Lomax, Zack; Ashworth, Travis; Smith, Ross T.; Tony Huang and Arindam DeyThis project investigates a novel method of engaging older adults in meaningful mealtime social interactions through the use of Mixed Reality technology. We propose a novel dining system that aims to facilitate interpersonal interactions and enhance meal consumption in socially isolated older adults. We created a prototype which allowed the target audience to test and discuss our concept so we can iteratively improve a user oriented design.Item Tablet Fish Tank Virtual Reality: a Usability Study(The Eurographics Association, 2017) Kongsilp, Sirisilp; Ruensuk, Mintra; Dailey, Matthew N.; Komuro, Takashi; Tony Huang and Arindam DeyIn this paper, we describe the development a tablet FTVR prototype that incorporates both motion parallax and stereo cues with the use of easy-to-find hardware. We also present findings of a usability study based on the prototype.Item Tactile Representation of Image in a Plane Actuator(The Eurographics Association, 2017) Lim, Jeong Mook; Oh, Changmok; Jeong, Hyun-Tae; Tony Huang and Arindam DeyOur study investigated the effect of vibration elements on the recognition of texture in a planar type actuator. A planar type actuator is highly advantageous in naturally conveying the texture of a graphic object on a large-sized touch screen display to a user, which can considerably improve the user's experience when interacting with such screens. In order to investigate the effect of frequency and amplitude elements of vibration on texture representation, we analyzed the texture image quantitatively and conducted a user experiment to find the vibration elements that best matched a texture. Experimental results show that controlling frequency is more effective in expressing texture than controlling amplitude, but in a certain frequency band, different texture can be represented by changing the amplitude only.
