Interacting With Grasped Objects In Expanded Haptic Workspaces Using The Bubble Technique, Ryan Andrew Pavlik, Judy M. Vance 2017 Iowa State University

Interacting With Grasped Objects In Expanded Haptic Workspaces Using The Bubble Technique, Ryan Andrew Pavlik, Judy M. Vance

Judy M. Vance

Haptic force-feedback can provide useful cues to users of virtual environments. Body-based haptic devices are portable but the more commonly used ground-based devices have workspaces that are limited by their physical grounding to a single base position and their operation as purely position-control devices. The “bubble technique” has recently been presented as one method of expanding a user's haptic workspace. The bubble technique is a hybrid position-rate control system in which a volume, or “bubble,” is defined entirely within the physical workspace of the haptic device. When the device's end effector is within this bubble, interaction is through ...


Rapid Development Of Natural User Interaction Using Kinect Sensors And Vrpn, Timothy B. Morgan, Diana Jarrell, Judy M. Vance 2017 Iowa State University

Rapid Development Of Natural User Interaction Using Kinect Sensors And Vrpn, Timothy B. Morgan, Diana Jarrell, Judy M. Vance

Judy M. Vance

The availability of low-cost natural user interaction (NUI) hardware took a significant step forward in 2010 with the introduction of the Microsoft Kinect. Despite significant work on the available software development kits for the Kinect, tasks beyond simple single-Kinect skeleton tracking remain challenging to implement. This paper introduces a software tool that significantly accelerates the prototyping and implementation of NUI in virtual reality, particularly for developers with limited programming skills. This is achieved by creating a graphical user interface to provide a consistent development environment for defining Kinect settings and voice commands. This is coupled with a server to transmit ...

Industry Use Of Virtual Reality In Product Design And Manufacturing: A Survey, Leif P. Berg, Judy M. Vance

Mechanical Engineering Publications

In 1999, Fred Brooks, virtual reality pioneer and Professor of Computer Science at the University of North Carolina at Chapel Hill, published a seminal paper describing the current state of virtual reality (VR) technologies and applications (Brooks in IEEE Comput Graph Appl 19(6):16, 1999). Through his extensive survey of industry, Brooks concluded that virtual reality had finally arrived and “barely works”. His report included a variety of industries which leveraged these technologies to support industry-level innovation. Virtual reality was being employed to empower decision making in design, evaluation, and training processes across multiple disciplines. Over the past two ...

An Application Of High Fidelity Ftds For Ab Initio Pilot Training: The Way Ahead, Nickolas D. Macchiarella, Tim Brady, Brandon S. Lyon

Tim Brady

"Decreases in simulation costs and increases in aircraft training costs led to the need for further investigation into the application of simulation-based training. Researchers conducted an eighteen-month study using ab initio student pilots as participants. This study applied a Federal Aviation Administration (FAA) approved, Part 142, flight-training curriculum that included 60% flight training device (FTD) use. Researchers identified five causal factors that warranted further investigation. The causal factors identified were visual fidelity, procedural similarity, dynamic flight environment, difficulty of task, and visual scanning and response. These causal factors have the potential to affect transfer of training (ToT) from simulated flight ...


Empath-D: Empathetic Design For Accessibility, CHOO TSU WEI, KENNY, Rajesh Krishna BALAN, Kiat Wee Tan, Archan MISRA, Youngki LEE 2017 Singapore Management University

Empath-D: Empathetic Design For Accessibility, Choo Tsu Wei, Kenny, Rajesh Krishna Balan, Kiat Wee Tan, Archan Misra, Youngki Lee

Research Collection School Of Information Systems

We describe our vision for Empath-D, our system to enable Empathetic User Interface Design. Our key idea is to leverage Virtual and Augmented Reality (VR / AR) displays to provide an Immersive Reality environment, where developers/designers can emulate impaired interactions by elderly or disabled users while testing the usability of their applications. Our early experiences with the Empath-D prototype show that Empath-D can emulate a cataract vision impairment of the elderly and guide designers to create accessible web pages with less mental workload.


Hindsight: Encouraging Exploration Through Direct Encoding Of Personal Interaction History, MI Feng, Cheng Deng, Evan M. Peck, Lane Harrison 2017 Worcester Polytechnic Institute

Hindsight: Encouraging Exploration Through Direct Encoding Of Personal Interaction History, Mi Feng, Cheng Deng, Evan M. Peck, Lane Harrison

Faculty Journal Articles

Physical and digital objects often leave markers of our use. Website links turn purple after we visit them, for example, showing us information we have yet to explore. These “footprints” of interaction offer substantial benefits in information saturated environments - they enable us to easily revisit old information, systematically explore new information, and quickly resume tasks after interruption. While applying these design principles have been successful in HCI contexts, direct encodings of personal interaction history have received scarce attention in data visualization. One reason is that there is little guidance for integrating history into visualizations where many visual channels are already ...


Unboxing Cluster Heatmaps, Sophie J. Engle, S. Whalen, Alark Joshi, K. Pollard 2017 University of San Francisco

Unboxing Cluster Heatmaps, Sophie J. Engle, S. Whalen, Alark Joshi, K. Pollard

Computer Science

Background: Cluster heatmaps are commonly used in biology and related fields to reveal hierarchical clusters in data matrices. This visualization technique has high data density and reveal clusters better than unordered heatmaps alone. However, cluster heatmaps have known issues making them both time consuming to use and prone to error. We hypothesize that visualization techniques without the rigid grid constraint of cluster heatmaps will perform better at clustering-related tasks.

Results: We developed an approach to “unbox” the heatmap values and embed them directly in the hierarchical clustering results, allowing us to use standard hierarchical visualization techniques as alternatives to cluster ...


Handling Relationships In A Wiki System, Yashi Kamboj 2016 San Jose State University

Handling Relationships In A Wiki System, Yashi Kamboj

Master's Projects

Wiki software enables users to manage content on the web, and create or edit web pages freely. Most wiki systems support the creation of hyperlinks on pages and have a simple text syntax for page formatting. A common, more advanced feature is to allow pages to be grouped together as categories. Currently, wiki systems support categorization of pages in a very traditional way by specifying whether a wiki page belongs to a category or not. Categorization represents unary relationship and is not sufficient to represent n-ary relationships, those involving links between multiple wiki pages.

In this project, we extend Yioop ...


Web-Based Integrated Development Environment, Hien T. Vu 2016 San Jose State University

Web-Based Integrated Development Environment, Hien T. Vu

Master's Projects

As tablets become more powerful and more economical, students are attracted to them and are moving away from desktops and laptops. Their compact size and easy to use Graphical User Interface (GUI) reduce the learning and adoption barriers for new users. This also changes the environment in which undergraduate Computer Science students learn how to program. Popular Integrated Development Environments (IDE) such as Eclipse and NetBeans require disk space for local installations as well as an external compiler. These requirements cannot be met by current tablets and thus drive the need for a web-based IDE. There are also many other ...

Cast2face: Assigning Character Names Onto Faces In Movie With Actor-Character Correspondence, Guangyu Gao, Mengdi Xu, Jialie Shen, Huangdong Ma, Shuicheng Yan

Research Collection School Of Information Systems

Automatically identifying characters in movies has attracted researchers' interest and led to several significant and interesting applications. However, due to the vast variation in character appearance as well as the weakness and ambiguity of available annotation, it is still a challenging problem. In this paper, we investigate this problem with the supervision of actor-character name correspondence provided by the movie cast. Our proposed framework, namely, Cast2Face, is featured by: 1) we restrict the assigned names within the set of character names in the cast; 2) for each character, by using the corresponding actor and movie name as keywords, we retrieve ...


Hashtag Recommendation With Topical Attention-Based Lstm, Yang LI, Ting LIU, Jing JIANG, Liang ZHANG 2016 Singapore Management University

Hashtag Recommendation With Topical Attention-Based Lstm, Yang Li, Ting Liu, Jing Jiang, Liang Zhang

Research Collection School Of Information Systems

Microblogging services allow users to create hashtags to categorize their posts. In recent years,the task of recommending hashtags for microblogs has been given increasing attention. However,most of existing methods depend on hand-crafted features. Motivated by the successful use oflong short-term memory (LSTM) for many natural language processing tasks, in this paper, weadopt LSTM to learn the representation of a microblog post. Observing that hashtags indicatethe primary topics of microblog posts, we propose a novel attention-based LSTM model whichincorporates topic modeling into the LSTM architecture through an attention mechanism. Weevaluate our model using a large real-world dataset. Experimental results ...


Museum 4.0 As The Future Of Steam In Museums, Mark Walhimer 2016 Tecnológico de Monterrey

Museum 4.0 As The Future Of Steam In Museums, Mark Walhimer

The STEAM Journal

Informal STEAM (Science, Technology, Engineering, Art and Math) activities (programs) and exhibits are common in science centers, children’s museums and natural history museums. As museums change to Museum 4.0 models (1), the STEAM exhibits and programs in museums also change. Museums 4.0 is the transformation of museums from a monolithic fixed location institution to a nimble community driven event driven organization. The Museum 4.0 becomes personalized to the visitor without fixed outcomes and without the physical restrictions of a single fixed location. As museums evolve to a Museum 4.0 model with visitor lead activities, STEAM ...

Marim: Mobile Augmented Reality For Interactive Manuals, Tam Nguyen, Dorothy Tan, Bilal Mirza, Jose Sepulveda

Tam Nguyen

In this work, we present a practical system which uses mobile devices for interactive manuals. In particular, there are two modes provided in the system, namely, expert/trainer and trainee modes. Given the expert/trainer editor, experts design the step-by-step interactive manuals. For each step, the experts capture the images by using phones/tablets and provide visual instructions such as interest regions, text, and action animations. In the trainee mode, the system utilizes the existing object detection and tracking algorithms to identify the step scene and retrieve the respective instruction to be displayed on the mobile device. The trainee then ...


Static Saliency Vs. Dynamic Saliency: A Comparative Study, Tam Nguyen, Mengdi Xu, Guangyu Gao, Mohan Kankanhalli, Qi Tian, Shuicheng Yan 2016 University of Dayton

Static Saliency Vs. Dynamic Saliency: A Comparative Study, Tam Nguyen, Mengdi Xu, Guangyu Gao, Mohan Kankanhalli, Qi Tian, Shuicheng Yan

Tam Nguyen

Recently visual saliency has attracted wide attention of researchers in the computer vision and multimedia field. However, most of the visual saliency-related research was conducted on still images for studying static saliency. In this paper, we give a comprehensive comparative study for the first time of dynamic saliency (video shots) and static saliency (key frames of the corresponding video shots), and two key observations are obtained: 1) video saliency is often different from, yet quite related with, image saliency, and 2) camera motions, such as tilting, panning or zooming, affect dynamic saliency significantly.

Motivated by these observations, we propose a ...
