The results of the inclusion of Virtual Reality in the production line of an Industry Joalheira in the state of Bahia, a case study which was conducted in the elevenmonth period by a Startup consisting of two professional Designers and one Information Technology, between the years of 2008 and 2009. The production flow of this jewelery factory was losses due to continuous communication difficulties...
Smart Lighting Systems are designed to conserve energy without compromising the user's visual comfort. The system incorporates Smart Android Application (App) and communication technologies to adjust light intensities as per the user comfort and behavior, employing the smart sensors. This paper presents implementation of a Smart App for smart lighting system based on the location of the individual...
The use of playful interactions, clever metaphors, and wordplay are ways that we make computation more appealing to young people and more accessible and intuitive to everyone. But play is a culturally situated notion, and ways that we embed playfulness into our designs can carry unintended messages that encourage or discourage productive use. The focus of this talk is to introduce the term Value-driven...
Diagrams can be an effective means of communicating complex ideas and can aid ontology engineering. Indeed, domain experts often do not have the expertise required to understand or create the complex logical statements of an ontology in description logic (DL). This paper presents a visualisation method, concept diagrams, geared toward expressing assertions and class expression axioms alongside providing...
Traditional textual programming languages are poorly readable and difficult to learn, creating significant hurdles for practitioners of industry (such as electromechanical engineers). However, Graphical Programming Language (GPL), using graphical symbols to construct programs, is becoming increasingly popular as it is intuitive and easy to learn. They have been implemented in many specific areas (such...
While formal mathematical reasoning is the cornerstone of computer science, undergraduates often fail to appreciate the value of mathematical proof in their studies. To alleviate this problem, we propose a novel pedagogy uniting logical reasoning with proofs of program correctness along with a proof assistant, ORC2A, that helps students author proofs in this domain. One of the defining features of...
Blockly is an open source library that makes it easy to add block based visual programming to an app. It is designed to be flexible and supports a large set of features for different applications. It has been used for programming animated characters on a screen; creating story scripts; controlling robots; and even generating legal documents. But Blockly is not itself a language; developers who use...
Despite the substantial progress in recent years, the image captioning techniques are still far from being perfect. Sentences produced by existing methods, e.g. those based on RNNs, are often overly rigid and lacking in variability. This issue is related to a learning principle widely used in practice, that is, to maximize the likelihood of training samples. This principle encourages high resemblance...
Globally, there have been growing needs to form a project team structure with the members consisted of diverse talents in order for an enterprise to prompt creative and innovative views on business values created from projects. With this type of multi-cultural team, there are higher risk of conflicts occurred among the team members due to difference in perceptions on a type of team culture that the...
For developers concerned with a performance drop or improvement in their software, a profiler allows a developer to quickly search and identify bottlenecks and leaks that consume much execution time. Non real-time profilers analyze the history of already executed stack traces, while a real-time profiler outputs the results concurrently with the execution of software, so users can know the results...
When targeting embedded applications such as on-board visual localization for small Unmanned Air Vehicles (UAV), available hardware generally becomes a limiting factor. For this reason, the usual strategy is to rely on pure motion integration and/or restricting the size of the map, i.e. performing visual odometry. Moreover, if monocular vision is employed, due to the additional computational cost...
The emerging of BIM (Building Information Modeling) techniques will change traditional procedures of design and maintenance for electric substations. In addition, Computational Holography, supported by wearable computers, has the potential to allow simultaneous engineering work, based on mixed reality and computer vision capabilities. It is believed that this set of tools will increase engineering...
This paper presents a visual comfort considered light control method for energy savings in open-plan office and investigates its performance. Simulation and pilot testing results show that more than 60% energy savings could be achieved while providing recommended visual comfort level for each user. Since the proposed algorithm saves energy significantly compared to the previous light control policies...
Being equipped with an appropriate user interface, building operating systems are capable of providing transparent information on energy consumption and generation in the household and achieving interaction with residents to implement energy management and optimization. In order to help provide a reference for the design of a more comprehensive user interface for building operating systems in the...
This paper examines the critical importance of time to the experience of place and argues that time-based virtual heritage creates more engaging and affective virtual places supporting rich learning opportunities for heritage audiences. It examines the experience of place, heritage place and virtual place as instanced in state-of-the-art computer games. It discusses the use of heritage visualisation...
We address the problem of large scale image geo-localization where the location of an image is estimated by identifying geo-tagged reference images depicting the same place. We propose a novel model for learning image representations that integrates context-aware feature reweighting in order to effectively focus on regions that positively contribute to geo-localization. In particular, we introduce...
Automatic Image Annotation (AIA) is a challenging problem in the field of image retrieval, and several methods have been proposed. However, visually supporting this important tasks and reducing the semantic gap between low-level image features and high-level semantic concepts still remains a key issue. In this paper, we propose a visually supporting image annotation framework based on visual features...
In this paper, we propose an improved image retrieval method, dedicated to images of buildings/landmarks from urban environments. Locally detected key points are binary labelled as building or no-building using a SVM-based classifier. Thereafter, only key points labelled as building are retained. In this way, the data in the database vocabulary is reduced to only the relevant one and solely the relevant...
This paper presents software visualization tool that utilizes the modified city metaphor to represent software system and related analysis data in virtual reality environment. To better address all three kinds of software aspects we propose a new layouting algorithm that provides a higher level of detail and position the buildings according to the coupling between classes that they represent. Resulting...
The one of the most vital public transport problems in cities is discrepancy between transport systems and numerous requirements to urban mobility. One of the crucial tasks is optimization of bus stops location for purposes of public transport usability and convenience. Most of current methods of solving such problems omit various obstacles and models of pedestrian motion. The study proposes a new...
