Summary: Effective communication between those who are not fluent in a non-native language can potentially be quite difficult. The common language selected to be used throughout an exchange can encumber those who might not speak it as proficiently as others. Remote communication further heightens the difficulty since less channels are available for communication. We introduce HandVis, a video conferencing interface that visualizes elements of hand gesture, such as trajectory and amount. Gesture is intended to be a communicative tool that can compensate for language deficits. The results of a user study indicate how HandVis can be utilized constructively by less-proficient speakers during cross-lingual communication.

Summary: As a kind of interesting mobile application, Mobile Visual Search (MVS) has attracted extensive research efforts from both academy and industry. Most of the MVS systems adopt the client-server framework, in which transmission latency caused by the limited bandwidth in wireless network is a big problem. To address this problem, the state-of-the-art work focuses on designing low bit-rate descriptors for MVS. However, few work focuses on reducing the number of descriptors. To further reduce the latency, we propose a novel framework of MVS based on the weighted matching of dominant descriptor. Firstly, we present an affinity propagation based algorithm for dominant descriptor selection. Secondly, we propose a weighted feature matching method to consider the differences of dominant descriptors in feature matching. By the proposed framework, we not only reduce the network latency in MVS, but also avoid transmitting useless descriptors to improve the retrieval accuracy of MVS. The experimental results on Stanford MVS data set show that when using CHoG descriptors, the proposed framework outperforms the existing framework by reducing more than 40% of the amount of data transmission and increasing 5% of the average retrieval accuracy.

Summary: Wearable technology used in spaceflight has many applications. Electronic sensing, interaction, and computing designed into comfortable on-body form factors has the potential to augment human capabilities while improving safety, efficiency, autonomy, and ergonomics. This paper discusses our design methods and approach to improving the E-SEWT (Electronic-textile System for the Evaluation of Wearable Technology) project for The Wearable Electronics Application and Research Lab (WEAR Lab) in the Avionic Systems Division at the NASA Johnson Space Center (JSC).
The E-SEWT project is a design-lead study in the form and function of a reconfigurable smart garment to be worn on board the International Space Station (ISS). This specialized garment consists of a base unit and removable sensor components called "swatches." This configuration allows the garment to be customized by the wearer to meet their needs to complete a particular task or to suit their personal preferences. The values of a smart garment with a variety of reconfigurable modular units include customization between wearers and tasks, ease in replacing parts and/or updating components for both replacement and testing and flexibility in prototyping and eventually manufacturing. The focus of the design solutions evolved through a process of interacting with test users with a focus on mobility, ergonomics comfort, and ease of use while maintaining optimal data flow.

Summary: Self-monitoring of blood glucose technique provides diabetic mellitus patients a simple and real-time method to monitor their blood sugar at home. In order to understand the interface design problems in home-use glucose meters, the aim of this study was to realize if senior users were able to easily and effectively operate glucose meters via usability evaluation. Five senior users of above 65 years old who never use home-use glucose meters before were recruited to operate typical tasks: a. changing lancet, b. inserting a strip to turn on the meter, c. lancing, d. waiting for the result and e. discarding lancet. The experiment process was recorded for further interview. The results demonstrated that the key factors that caused operation errors were found on lancing device and test strip instead of the glucose meter. Especially for seniors that had memory degradations, they needed side by side assistance to finish the tasks.

Summary: Formal intraoperative assessments of surgical residents are often completed with pencil-and-paper forms, leading to a low rate of compliance with residency program guidelines. An online tool was developed for the evaluation of residents by attending physicians in the OR. Usability testing was conducted using two groups of users, one expert and the other naïve, using a newly developed variant of rapid iterative testing methodology called DONE-RITE. The tool was developed and refined over a series of rapid iterations where user interface and domain-specific usability issues were addressed by the naïve and expert user groups, respectively. The end result was the quick development of the online tool, which the expert users agreed was convenient to use in the OR and was likely to improve compliance with resident assessment guidelines.

Habitag: virtually home Student design / Heng, Samuel Hsein Chin / Lin, Kevin Jianxiong / Lim, Teng Chek / Soh, Kaili Agatha Extended Abstracts of ACM CHI'12 Conference on Human Factors in Computing Systems 2012-05-05 v.2 p.1279-1284

Summary: In Singapore, many young adults do not move out of their family home even after marriage. We conducted several interviews and identified that moving into the marital home is a problem for many newlyweds. Using data from surveys, interviews and a cultural probe, we designed Habitag -- a private smartphone application that targets newly married couples in Singapore, helping them to plan for and adjust to their new home in a collaborative and playful manner. Testing results indicate that Habitag may help to reduce the amount of frustration and difficulties that newlyweds face during these critical processes. Finally, we discuss Habitag's potential transferability to other Asian countries.

Summary: This paper proposes an improved algorithm based on Active Appearance Models (AAM) and applies on a real-time 3D video conference system with a novel 3D display device which can pop out an avatar out of the display in the air. The proposed algorithm utilizes an improved Adaboost algorithm [1] for face detection based on skin color information. Facial feature points are then tracked based on AAM [2] and we improved the algorithm to determine the rate of closing eyelid and the rotation angle of eyeballs. The novel 3D display device projects digital images on an actual human like object as an avatar and pops out a 3D image in the air via an optical module. With the proposed system, users can interactive intuitively with a popped 3D avatar. This system provides more realistic and representative visual effect for interaction in a video conference.

Summary: Fast-developing social networking sites (SNS) have become the major media by which people develop their personal network online in recent years. To explore factors affecting user's joining SNS, this study applies network externalities and motivation theory to explain why people continue to join SNS. This study used an online questionnaire to conduct empirical research, and collected and analyzed data of 402 samples by structural equation modeling (SEM) approach. The findings show that enjoyment is the most influential factor in people's continued use of SNS, followed by number of peers, and usefulness. The number of peers and perceived complementarity have stronger influence than the number of members on perceived benefits (usefulness and enjoyment). This work also ran clustering analysis by gender, which found notable difference in both number of peers and number of members between men and women. The number of peers is an important factor affecting the continued intention to use for women but not for men; the number of members has no significant effect on enjoyment for men. The findings suggest that gender difference also produces different influences. The implication of research and discussions provides reference for SNS operators in marketing and operation.

Understanding e-learning continuance intention: a negative critical incidents perspective / Lin, Kan-Min / Chen, Nian-Shing / Fang, Kwoting Behaviour and Information Technology 2011-01-01 v.30 n.1 p.77-89

Summary: This study develops a model to examine the key drivers of users' continuance intention of e-learning, based on negative critical incidents (NCIs) standpoints. The developed research model is tested empirically using a field survey of 230 users. This study finds that users' past service encounters (NCIs), belief (perceived ease of use and usefulness), satisfaction (quality attributes cumulative satisfaction and overall satisfaction) and attitude are key antecedents of continued usage intention. Four dimensions of both NCIs and quality attributes in e-learning (administration procedures, e-learning system functionality, instructional process and human interaction) are explored in this study. Results indicate that NCIs in teaching and administration are comparatively more important in determining user satisfaction and continuance intention. Further analysis finds that the recorded lecture content and the response time to users are the most critical problems in teaching and administration. In practice, this model can identify the key problems of satisfaction and continuance intention to help managers and teachers react promptly or make right decisions about how to better achieve higher user retention rates.

Summary: Identifying intent boundary in search query logs is important for learning users' behaviors and applying their experiences. Time-based, query-based, and cluster-based approaches are proposed. Experiments show that the integration of intent clusters and dynamic time model performs the best.

"Integrare", a Collaborative Environment for Behavior-Oriented Design / Wen, Lian / Colvin, Robert / Lin, Kai / Seagrott, John / Yatapanage, Nisansala / Dromey, R. Geoff CDVE 2007: International Conference on Cooperative Design, Visualization, and Engineering 2007-09-16 p.122-131

Summary: In this paper, we introduce a new cooperative design and visualization environment, called "Integrare", which supports designers and developers in building dependable, component-based systems using a new behavior-oriented design method. This method has advantages in terms of its abilities to manage complexity, find defects and make checks of dependability. The environment integrates and unifies several tools that support multiple phases of the design process, allowing them to interact and exchange information, as well as providing efficient editing capabilities. It can help formalize individual natural language functional requirements as Behavior Trees. These trees can be composed to create an integrated tree-like view of all the formalized requirements. The environment manages complexity by allowing multiple users to work independently on requirements translation and tree editing in a collaborative mode. Once a design is constructed from the requirements, it can be visually simulated with respect to an underlying operational semantics, and formally verified by way of a model checker.

Summary: Microsoft Visio is one of the most prevalent commercial single-user graphic editing systems, which can be used to create a wide variety of business and technical drawings. It is desirable to leverage single-user Visio system for multi-user real-time collaboration. One feature that distinguishes Visio from other graphic editing systems is that formulas, a type of constraint, are defined in Visio to express the attributes of each graphic object, and the relationship between different Visio graphic objects. The ability to describe shapes with constraints opens many possibilities for making shapes behave in complex and sophisticated ways, but satisfying constraints in the presence of concurrency in collaborative systems is a challenge. In this article, we introduce a collaborative Visio system, called CoVisio, which enables a group of users to view and edit the same Visio documents at the same time from different collaborating sites. The methods applied to develop CoVisio are generic and can be adopted to leverage other single-user systems that support constraints, such as Microsoft Excel, for multi-user collaboration.

Summary: We study the classification of news articles into emotions they invoke in their readers. Our work differs from previous studies, which focused on the classification of documents into their authors' emotions instead of the readers'. We use various combinations of feature sets to find the best combination for identifying the emotional influences of news articles on readers.

Efficient algorithms for Web services selection with end-to-end QoS constraints / Yu, Tao / Zhang, Yue / Lin, Kwei-Jay ACM Transactions on The Web 2007-05 v.1 n.1 p.6

ACM Digital Library Link

Summary: Service-Oriented Architecture (SOA) provides a flexible framework for service composition. Using standard-based protocols (such as SOAP and WSDL), composite services can be constructed by integrating atomic services developed independently. Algorithms are needed to select service components with various QoS levels according to some application-dependent performance requirements. We design a broker-based architecture to facilitate the selection of QoS-based services. The objective of service selection is to maximize an application-specific utility function under the end-to-end QoS constraints. The problem is modeled in two ways: the combinatorial model and the graph model. The combinatorial model defines the problem as a multidimension multichoice 0-1 knapsack problem (MMKP). The graph model defines the problem as a multiconstraint optimal path (MCOP) problem. Efficient heuristic algorithms for service processes of different composition structures are presented in this article and their performances are studied by simulations. We also compare the pros and cons between the two models.

Maintaining constraints in collaborative graphic systems: the CoGSE approach / Lin, Kai / Chen, David / Sun, Chengzheng / Dromey, Geoff Proceedings of the Ninth European Conference on Computer-Supported Cooperative Work 2005-09-18 p.185-204

Summary: A constraint specifies a relation or condition that must be maintained in a system. It is common for a single user graphic system to specify some constraints and provide methods to satisfy these constraints automatically. Constraints are even more useful in collaborative systems, which can confine and coordinate concurrent operations, but satisfying constraints in the presence of concurrency in collaborative systems is difficult. In this article, we discuss the issues and techniques in maintaining constraints in collaborative systems. In particular, we also proposed a novel strategy that is able to maintain both constraints and system consistency in the face of concurrent operations. The strategy is independent of the execution orders of concurrent operations and able to retain the effects of all operations in resolving constraint violation. The proposed strategy has been implemented in a Collaborative Genetic Software Engineering system, called CoGSE, for maintaining the tree structure constraint. Specific issues related to CoGSE are also discussed in detail.

Summary: A constraint expresses a relationship among one or more variables. Constraints are very useful in the development of collaborative applications, such as collaborative CAD and CASE systems, but satisfying constraints in the presence of concurrency in collaborative systems is difficult. In this article, we discuss the issues and techniques in maintaining constraints in collaborative systems. In particular, we also proposed a novel priority strategy that is able to maintain both constraints and system consistency in the face of concurrent operations. The strategy is able to resolve constraint violations in multi-constraint systems and is independent of the execution orders of concurrent operations. To illustrate the applicability of the proposed priority strategy, the applications of the approach in various collaborative systems are discussed in detail.

Summary: The Tutoring Research Group from the University of Memphis has developed a pedagogically effective Intelligent Tutoring System (ITS), called AutoTutor, that implements conversational dialog as a tutoring strategy for conceptual physics. Latent Semantic Analysis (LSA) is used to evaluate the quality of student contributions and determine what dialog moves AutoTutor gives. By modeling the students' knowledge in this fashion, AutoTutor successfully adapted its pedagogy to match the ideal strategy for students' ability.
