This position paper addresses the issue of startups and technical debt. Early stage startups condition makes creating technical debt an almost mandatory decision. Not managing technical debt can be deadly for a startup as fast product iteration cycle is necessary. We here introduce a technique for managing technical debt based on Visual Thinking. The technique addresses the problem of knowing how...
Human-robot teams can incorporate advanced technology such as distributed mobile sensor networks, integrated communications, visualization technology, and other means to acquire and assess information. These factors can greatly affect mission effectiveness, safety, and survivability, by providing critical information and suggesting courses of action. However, information overload can result. Tactical...
There is an increasing need to quickly understand the contents log data. A wide range of patterns can be computed and provide valuable information: for example existence of repeated sequences of events or periodic behaviors. However patternminingtechniquesoftenproducemanypatternsthathave to be examined one by one, which is time consuming for experts. On the other hand, visualization techniques are...
Emergency command and control centers (CC) are integrated facilities to assist and handle crisis situations. In these CCs, operators suffer both with information shortage and overload. This paper focuses on the information overload problem. Operators often do not have adequate access to information that may be relevant in the decision-making process. In many CC centers, information is stored without...
In designing BYOB and Snap/, we wanted to extend the Scratch idea of visual metaphors for control structures to include anonymous procedures and higher order functions. We describe the iterations in the design leading to the current "grey ring" notation.
Having worked with transposition of domain knowledge in digital and card games, we propose a novel approach for enabling groups of primary school pupils to express their shared understanding of a topic, the group can represent their knowledge by creating a trading card game (with custom cards and rules) instead of using diagrammatical formalisms. A kit and a special design method have been devised...
Visualization of management tools has become a must in the past decade. Its importance cannot be neglected; visual signs define the direction our brain pays attention to, and therefore affect deeply what and how human beings contemplate their environment. Recent tools in business management such as business models include visual elements to support the attracting of attention. A vast amount of literature...
In this paper, the authors report the initial development stages of Jeliot Mobile, a tool that aims to bring the benefits of visualization to the new generation of learners that makes use of new technologies. From the research point of view the authors want to 1) frame the development of the tool in the socio-constructivist paradigm, and 2) bring the learner-centeredness via participatory design....
Top down image semantics play a major role in predicting where people more attend in images. In the state of computational models of human visual attention incorporate high level object detections signifying top down image semantics in a separate channel along with other bottom up saliency channels. The different occurrences of objects in a scene also to attract our attention and this interaction...
TPFOSSS (Think-Pair Free Open Source Software-Share) is a cooperative learning activity and modified activity of TPS in which free open source software e.g. Parsing Simulator for Compiler Construction or JFLAP simulator for Theory of Computation etc. Can be used in TPS activity. Providing "think time" in TFOSSPS improves quality of student responses. This activity develops skills of sharing...
This position paper explores the idea that the blackboard system metaphor can be used to enrich collaborative ACM systems where there is need to mobilize knowledge workers with different areas of expertise for solving a case. Inspired by this metaphor, we outline how blackboards can be perceived both as a snapshot visualization of case folder with goal achievement status across lines of work, and...
Achieving a smooth flow of work through the system is a goal for many teams and organizations that embrace agile and lean approaches. However, the flow of work faces many impediments as it flows through teams and organizations. Agile and lean approaches can reveal impediments that impact teams and organizations. Often at the start of their agile transition, but also frequently after the initial transition,...
In today's social context, the role of designers has been shifting gradually with design evolution. Along with the proposition of design thinking, service design and transformation design, designers work more with people than merely for people. And that makes designers play the role of facilitators more in the design processes to promote co-design with various stakeholders for solutions and strategies...
This paper extends the bag-of-visual-words representations to a bag-of-visual-phrases model. The introduced bag-of-visual-phrases representation is constructed upon a proposed method for probabilistic description of co-occurring visual words, which is adapted for each reference word. This bag-of-visual-phrases representation implicitly encodes spatial relationships among visual words, thus being a...
Using of Kanban in software development is an emerging topic. This systematic literature review was conducted in order to analyze the current trend of Kanban usage in software development and to identify the obtained benefits and involved challenges. The search strategy resulted in 492 papers, of which 19 were identified as primary studies relevant to our research. The main reported benefits of using...
This work aims to explore the benefits and potential uses of Augmented Reality technology for supporting communication in lectures and presentations. In this paper we present the architecture and implementation of an Augmented Presentation Feedback System (APFs). The system allows a speaker equipped with an Augmented Reality Head-Mounted Display to visualize visual cues depicted over the listeners'...
In this short position paper, we explore three questions regarding cyber security visualization: (1) why cyber security visualization has not been more effective in the past, (2) how visualization can be utilized in cyber security, and (3) how to evaluate cyber security visualization.
Bloat, and particularly object churn, is a common performance problem in framework-intensive applications. Object churn consists of an excessive use of temporary objects. Identifying and understanding sources of churn is a difficult and labor-intensive task, despite recent advances in automated analysis techniques. We present an interactive visualization approach designed to help developers quickly...
Spatio-Temporal Interest Point (STIP) has been widely used for human action recognition. However, the performance of the STIP based methods are still limited in realistic datasets which often include large variations in illuminations, viewpoints and camera motions. One reason of the low performance is that the STIPs only reflect the local change in videos, which is not enough to obtain stable informative...
Tag recommendation allows mitigating the amount of user effort needed to annotate images. Assuming that favorite images and their associated tags are indicative of the visual and topical interests of users, this paper proposes a personalized image tag recommendation technique that makes use of favorite image context. Specifically, to recommend tags for a newly uploaded image, we propose to take advantage...
