  • Massively Parallel Discrete Element Method Simulations on Graphics
           Processing Units
    • Authors: Steuben J; Mustoe G, Turner C.
      Abstract: This paper outlines the development and implementation of large-scale discrete element method (DEM) simulations on graphics processing hardware. These simulations, as well as the topic of general-purpose graphics processing unit (GPGPU) computing, are introduced and discussed. We proceed to cover the general software design choices and architecture used to realize a GPGPU-enabled DEM simulation, driven primarily by the massively parallel nature of this computing technology. Further enhancements to this simulation, namely, a more advanced sliding friction model and a thermal conduction model, are then addressed. This discussion also highlights some of the finer points and issues associated with GPGPU computing, particularly surrounding the issues of parallelization, synchronization, and approximation. Qualitative comparison studies between simple and advanced sliding friction models demonstrate the effectiveness of the friction model. A test problem and an application problem in the area of wind turbine blade icing demonstrate the capabilities of the thermal model. We conclude with remarks regarding the simulations developed, future work needed, and the general suitability of GPGPU architectures for DEM computations.

  • On Architecting and Composing Engineering Information Services to Enable
           Smart Manufacturing
    • Authors: (Serm) Kulvatunyou B; Ivezic N, Srinivasan V.
      Abstract: Engineering information systems play an important role in the current era of digitization of manufacturing, which is a key component to enable smart manufacturing. Traditionally, these engineering information systems spanned the lifecycle of a product by providing interoperability of software subsystems through a combination of open and proprietary exchange of data. But research and development efforts are underway to replace this paradigm with engineering information services that can be composed dynamically to meet changing needs in the operation of smart manufacturing systems. This paper describes the opportunities and challenges in architecting such engineering information services and composing them to enable smarter manufacturing.

  • A Novel Approach to the Design and Development of an Interactive Learning
           App for Automotive In-Vehicle Infotainment Systems
    • Authors: Chen Y; Tonshal B, Mitra P, et al.
      Abstract: This paper presents the design, architecture, and implementation of “MyFord Touch Guide,” a novel, cross-platform mobile app that delivers an interactive and experiential learning experience for the Ford SYNCTM with MyFord TouchTM in-vehicle infotainment (IVI) system. This app incorporates the production of MyFord Touch graphical user interface for an interactive learning experience. Additionally, it integrates a host of video tutorials featuring a computer-animated character, which offers an insightful, self-guided tour experience of the essential features and functions of the system. MyFord Touch Guide is a cross-platform app and based on a “hybrid” app architecture that uses both native mobile and web technologies. Feedbacks gathered from multiple nation-wide surveys indicated that our approach was effective as an interactive, mobile learning app.

  • Geometry Assurance Integrating Process Variation With Simulation of
           Spring-In for Composite Parts and Assemblies
    • Authors: Jareteg C; Wärmefjord K, Cromvik C, et al.
      Abstract: Geometrical variation and deviation in all the manufacturing processes affect the quality of the final product. Therefore, geometry assurance is an important tool in the design phase of a new product. In the automotive and aviation industries where the use of composite parts is increasing drastically, new tools within variation simulations are needed. Composite parts tend to deviate more from nominal specification compared to metal parts. Methods to simulate the manufacturing process of composites have been developed before. In this paper, we present how to combine the process variation simulation of composites with traditional variation simulations. The proposed method is demonstrated on a real complex subassembly, representing part of an aircraft wing-box. Since traditional variation simulation methods are not able to capture the spring-in and the special deviation behavior of composites, the proposed method adds a new feature and reliability to the geometry assurance process of composite assemblies.

  • Sentiment Root Cause Analysis Based on Fuzzy Formal Concept Analysis and
           Fuzzy Cognitive Map
    • Authors: Park S; Kim Y, Baik D.
      Abstract: Feature-level sentiment analysis can retrieve the sentimental preferences for the features of products but cannot retrieve the causes of the preferences. Previous sentiment analysis methods used sentiment words to calculate the sentiment polarity for specific features but could not utilize neutral sentiment words, even when they constituted a large proportion of the sentiment words. Fault diagnosis can extract causes and determine the root cause by using factual information and the cause-effect relation, but is not used for sentiment data. For the retrieval of sentiment root causes, we propose a sentiment root cause analysis method for user preferences. We consider sentiment relations based on fuzzy formal concept analysis (FFCA) to extend hierarchical feature-level sentiment analysis. A hierarchical relation of neutral sentiment words and explicit causal relation based on causal conjunctions is utilized to retrieve the cross features of root causes. A sentiment root cause is determined from the extracted causes to explain the preference of a sentiment expression by using a fuzzy cognitive map with a relations method. We demonstrate a factual ontology and sentiment ontology based on a feature ontology for clothing products. We evaluated the proposed sentiment root cause analysis method and verified that it is improved as compared with term frequency-based methods and sentiment score analysis.

  • Proto-TAI++: Exploring Perceptually Consistent Creation of Planar Shape
           Assemblies Through Multimodal Tangible Interactions
    • Authors: Piya C; Vinayak , Ramani K.
      Abstract: We explore tangible 3D interactions that allow for geometric and perceptual correspondence between a midair modality and the 3D elements it controls. To demonstrate our approach, we use a concrete application scenario through Proto-TAI++, a multimodal system using pen-based drawing of planar shapes and their subsequent midair assembly via a hand-held planar proxy. The planarity of the proxy is a key element that physically embodies virtual planar shapes during 3D manipulation. We also investigate advanced operations such as patterning and blending using asymmetric bimanual interactions that augment midair motion with multitouch gestures. We describe a three-stage user evaluation with our system wherein our goal is to (a) study the effectiveness of the planar proxy as a tangible 3D modality, (b) contrast key features of our approach with a GUI-based planar shape assembly system, and (c) evaluate user experience and performance in creative tasks using Proto-TAI++.

  • Blended Spaces for Integrated Creativity and Play in Design and
           Engineering Processes
    • Authors: Wendrich RE.
      Abstract: The umpire whispers: “Please Play.” We sort of play. But it is all hypothetical, somehow. Even the “we” is theory: I never get quite to see the distant opponent, for all the apparatus of the game (Wallace, 2011, Infinite Jest, Hachette, UK). We find no reason to abandon the notion of play as a distinct and highly important factor in the world's life and doings. All play means something. If we call the active principle that makes up the essence of play, “instinct,” we explain nothing; if we call it “mind” or “will” we say too much. However, we may regard it, the very fact that play has a meaning implies a nonmaterialistic quality in the nature of the thing itself (Huizinga, 2014, Homo Ludens, Ils 86, Routledge, London.). This paper builds on the notion of integration of creativity and play in design and engineering environments. We show results of ongoing research and experimentation with cyber-physical systems (CPS) and multimodal interactions. The use of computational tools for creative processing and idea generation in design and engineering are mostly based on commonly available 2D or 3D CAD programs, applications, and systems. Computer-generated creativity is mostly based on combinatorial power and computational algorithms of the intrinsic system duly orchestrated by the user to manifest outcomes on a variety of processes. However, integrated game-based CPS ecosystems could enhance the uptake of play, imagination, and externalization within the design and engineering process.

  • Visualization of Headlight Illumination for the Virtual Prototyping of
           Light-Based Driver–Assistance Systems
    • Authors: Berssenbrügge J; Trächtler A, Schmidt C.
      Abstract: Driving simulators that are capable of simulating a virtual drive at night are increasingly used for the virtual prototyping of light-based driver–assistance systems (DAS). Here, the interplay between driver and assistance system, which enhances the illumination of the road ahead of the vehicle, is investigated. For such investigations, special driving simulators are applied that not only enable a standard driving simulation but also cover the special requirements for the visualization of a driving scenery at night, the simulation of automotive headlights during a virtual drive at night, and the interface to a headlight control module (HCM) that operates the physical headlight prototypes. In this paper, we present the visualization system of the reconfigurable driving simulator from the research project TRAFFIS. We describe the special application focus on the virtual prototyping of a light-based DAS from our project partner Varroc Lighting Systems. The light-based DAS is based on a headlight prototype that combines a glare-free high-beam (GFHB) function and a predictive adaptive frontlighting system (PAFS) for glare-free driving with maximized headlight time.

  • Evaluating Industrial Products in an Innovative Visual-Olfactory
    • Authors: Bordegoni M; Carulli M.
      Abstract: The sense of smell has a great importance in our daily life. Recently, smells have been used for marketing purposes for improving the people's mood and for communicating information about products as household cleaners and food. However, the scent design discipline can be used for creating a “scent identity” of these products not traditionally associated to a specific smell, in order to communicate their features to customers. In the area of virtual reality (VR), several researches concerned the integration of smells in virtual environments. The research questions addressed in this paper concern if virtual prototypes (VP), including smell simulation, can be used for evaluating products as effectively as studies performed in real environments, and also if smells can enhance the users' sense of presence in virtual environments. For this purpose, a VR experimental framework including a prototype of a wearable olfactory display (wOD) has been set up, and experimental tests have been carried out.

  • Dexterous Grasping Tasks Generated With an Add-on End Effector of a Haptic
           Feedback System
    • Authors: Leon J; Dupeux T, Chardonnet J, et al.
      Abstract: The simulation of grasping operations in virtual reality (VR) is required for many applications, especially in the domain of industrial product design, but it is very difficult to achieve without any haptic feedback. Force feedback on the fingers can be provided by a hand exoskeleton, but such a device is very complex, invasive, and costly. In this paper, we present a new device, called HaptiHand, which provides position and force input as well as haptic output for four fingers in a noninvasive way, and is mounted on a standard force-feedback arm. The device incorporates four independent modules, one for each finger, inside an ergonomic shape, allowing the user to generate a wide range of virtual hand configurations to grasp naturally an object. It is also possible to reconfigure the virtual finger positions when holding an object. The paper explains how the device is used to control a virtual hand in order to perform dexterous grasping operations. The structure of the HaptiHand is described through the major technical solutions required and tests of key functions serve as validation process for some key requirements. Also, an effective grasping task illustrates some capabilities of the HaptiHand.

  • Virtual Tissue Cutting With Haptic Feedback Using a Hybrid Actuator With
           DC Servomotor and Magnetorheological Brake
    • Authors: Gonenc B; Gurocak H.
      Abstract: Surgical training is an important and recent application where haptic interfaces are used to enhance the realism of virtual training simulators. Tissue cutting with surgical scissors is a common interaction mode in the simulations. The haptic interface needs to render a wide range of tissue properties and resistance forces accurately. In this research, we developed a hybrid haptic device made of a DC servomotor and a magnetorheological (MR) brake. The motor can provide fast dynamic response and compensate for inertia and friction effects of the device. But alone, it cannot supply high force levels and the sensation of stiff interaction with hard tissues such as tendons. On the other hand, the MR-brake can provide very stiff interaction forces yet cannot reflect fast dynamics that are encountered as the virtual scissors go through the tissue. The hybrid actuator developed in this work combines the two based on a control scheme that decomposes the actuator command signal into two branches considering each actuator's capabilities. It is implemented on a compact single degree-of-freedom (DOF) interface to simulate virtual tissue cutting with three different scissor types (Mayo, Metzenbaum, Iris) and four types of rat tissue (liver, muscle, skin, tendon). Results have shown close tracking of the desired force profile in all cases. Compared to just using a DC motor, the hybrid actuator provided a wider range of forces (up to 18 N) with fast response to render quick force variations without any instability for all simulated tissue and scissor types.
