Like in every process model, agile processes (e.g. Scrum, eXtreme Programming) depend on accurate estimations to enable meaningful prioritization, iteration- and release planning. The emphasis of this paper is on "Planning Poker", a widely used estimation technique in agile context. The goal is to identify inaccurate effort estimates to enable more precise project scheduling and release...
Analyze the background of the appearance of interaction design and compare it with the traditional product design, propose interactive experience design methods based on open source code and effective MAX 6 \ MSP design methods validated experimentally, establish engineering approach balanced between usability and accessibility from initial concept design to final product for industrial designing...
Entrepreneurial opportunities are a crucial starting point of the entrepreneurial process. However, reliable and replicable methods for systematically searching, framing, developing and assessing opportunities are still undeveloped. This article describes an action-research case study based on an experimental workshop performed in Beijing, China, in the context of an entrepreneurial platform called...
Physical activities play important role in having better health. However, due to the nature of our jobs, most of us have developed sedentary habits and it is very seldom that we find dedicated time for exercise or other physical activities. Sedentary behavior has been identified as an important factor in preventing good health and there is a need to push adults to carry out physical activities regularly,...
The development of software systems inevitably involves the detection and handling of inconsistencies. These inconsistencies can arise in system requirements, design specification and quite often in the descriptions that form the final implemented software product. Now days we see requirement engineers focusing their attention to achieve a solid system and user requirements. This involves requirement...
Organizations nowadays invest heavily in business intelligence (BI) systems to get insights from their increasingly large volumes of complex data, support decision making and achieve competitive advantages. The visualization capability of a BI system in terms of developing effective visualizations for addressing business problems is crucial to the success of BI. With the rapid advances achieved in...
For the digital forensic examiner, being able to perceive change-over-time supports the goal of being able to explain “what happened.” In this paper, we focus on the improvements brought to digital forensic analysis by the visualization of forensic data and its application to digital forensic data that records change-over-time, specifically for a directory-tree structure and its content. By perceiving...
Advertisement turns into recommendation, web services become independent apps, and mobile devices enforce context awareness. Recommendation as a Service (RaaS) turns into an independent application-based business. By analyzing the trends, the paper introduces a multi-dimensional evaluation scheme to characterize recommender systems. The chart is applied to different research implementations, emphasizing...
The success of context-aware systems depends on intuitive user interface designs which facilitate communication between multiple devices. This paper presents Throw It, a natural user interface for sharing objects between mobile devices using gaze and hand gestures. For enabling gesture control, Throw It includes an off-the-shelf monochrome camera with infrared lights and a hand-held 6 degree of freedom...
Large software projects are often based on libraries that provide abstractions for a particular domain such as writing database queries, staging, or constraint solving. The API provided by such a library can be considered a domain-specific language within the implementation language of the library, a so-called internal or embedded domain-specific language (eDSL). Embedding a DSL leverages the tool...
Coupling in an object-oriented context is often defined in terms of access to instance variables and methods of other classes. JavaScript, however, lacks static type information and classes, and instead features a flexible object system with prototypal inheritance. In order to determine coupling in JavaScript, we infer object types based on abstract interpretation of a program. Type inference depends...
In this paper we discuss the need for a new command and control (C2) approach for the practical deployment of Moving Target Defenses (MTDs) enterprise networks. We describe some of the requirements and constraints associated with the combined use of multiple moving target defenses, and introduce a human-agent teamwork approach for the command and control of MTDs. We introduce and discuss some of the...
Multi-scale parts-based models are particularly effective for recognizing non-segmented graphic symbols, i.e. the symbols interfered by other connecting or intersecting objects in the context. However, treating every symbol part and it features on every scale equally, despite some of them contributing little to the recognition, may lead to unnecessarily high dimensional representation of the symbol...
Multiple-labeling classification approaches attempt to handle applications that associate more than one label to a given sample. Since we have an increasing number of systems that are guided by such assumption, in this paper we have presented a multiple-labeling approach for the Optimum-Path Forest (OPF) classifier based on the problem transformation method. In order to validate our proposal, a multi-labeled...
In this research, we explore the use of visual tiling patterns (tilings for short) in the teaching of basic programming concepts to novice students. Tilings are made by connecting regular polygons side-by-side and their construction can be defined by the use of a simple set of commands. We believe tilings are a suitable context to situate the learning of elementary programming concepts for beginning...
We present a study on the use of the Microsoft Kinect (Kinect) to implement interactive urban environments that integrate smart tourism and smart learning. The tests were carried out on a prototype containing a set of apps whose navigation was inspired by smart phones and tablets navigation. The results show that the quality of the interaction and of the overall user experience is already mature to...
The research work aim to support the teacher's design activity and propose an adaptive process as part of an engineering design process framework based on patterns. The design process proposes teachers to design learning situation based on patterns according to their own design approach identified as pedagogical design scheme. A context-sensitive tool exploiting a library of patterns is being developed...
Tremendous amounts and types of information are available on today's battlefields. Military intelligence analysts are responsible for sifting through this information and providing commanders with the appropriate portion that is accurate, timely, and relevant to their particular mission characteristics. There is no doubt that analysts would benefit from automated tools to help them quickly identify...
Requirements elicitation research is reviewed using a framework categorising the relative ‘knowness’ of requirements specification and Common Ground discourse theory. The main contribution of this survey is to review requirements elicitation from the perspective of this framework and propose a road map of research to tackle outstanding elicitation problems involving tacit knowledge. Elicitation techniques...
Many researches are interested in the observation of learners' activities within a Technology-Enhanced Learning environment. This work is about how observation can be improved. We originally propose the concept of observation strategy. Such approach leads teachers-designers to design and specify the targeted observation, and all its components, as a dedicated artifact in relation with a learning scenario...
