HYBRID MOBILE AUGMENTED REALITY: WEB-LIKE CONCEPTS APPLIED TO HIGH RESOLUTION 3D OVERLAYS

Abstract. Mobile Augmented Reality (MAR) aligns toward current technological advances with more intuitive interfaces, realistic graphic content and flexible development processes. The case of overlaying precise 3D representations exploits their high penetration to induct users to a world where data are perceived as real counterparts. The work presented in this paper integrates web-like concepts with hybrid mobile tools to visualize high-quality and complex 3D geometry on the real environment. The implementation involves two different operational mechanisms: anchors and location-sensitive tracking. Three scenarios, for indoors and outdoors are developed using open-source and with no limit on distribution SDKs, APIs and rendering engines. The JavaScript-driven prototype consolidates some of the overarching principles of AR, such as pose estimation, registration and 3D tracking to an interactive User Interface under the scene graph concept. The 3D overlays are shown to the end user i) on top of an image target ii) on real-world planar surfaces and iii) at predefined points of interest (POI). The evaluation in terms of performance, rendering efficacy and responsiveness is made through various testing strategies: system and trace logs, profiling and ‗end-to-end‖ tests. The final benchmarking elucidates the slow and computationally intensive procedures induced by the big data rendering and optimization patterns are proposed to mitigate the performance impact to the non-native technologies.

The Validity of Learning Media Using Prezi Application Equipped with a Guidebook on Biodiversity Material for Students of Class X SMA

The development of Science and Technology (IPTEK) is so rapidly affecting the use of electronic technology in learning. Teachers are expected to be able to use multimedia in learning. One example of multimedia utilization in learning is the application for learning media in addition to PowerPoint presentations, namely the Prezi application. Prezi is an application that is used to make presentations more interesting. Prezi can contain text, images, videos and other presentation media placed on the presentation canvas and can be grouped in frames that have been provided. Most of the teachers who are not able to apply multimedia especially the Prezi application, it is necessary to have a guidebook to use the Prezi application so that teachers and students are able to use the application as a medium for learning. Therefore, the purpose of this study is to produce learning media using the Prezi application equipped with a guidebook on biodiversity material for high school class X students who are valid and practical.This type of research is research and development development research using the Instructional Development (IDI) model. The object of this research is learning media using the Prezi application equipped with a guidebook on biodiversity material for class X students.

Style Transfer for CNC Machine Input Data Preprocessing

Advances in deep neural networks have led to impressive results in recent years. The new technologies such as cross-domain adaptation, reinforcement learning and generative adversarial networks have shown a real promise for industrial and real-life applications. In this paper, the results of the experimental research on designing, training and implementation of the preprocessing algorithm for the computer numerical control machine input were presented. The algorithm of neural network transfer of artistic style has demonstrated wide possibilities in the field of generating graphic content. This paper demonstrates the possibility of using a generating neural network for the synthesis of stylized images that can be used as input images for a computer numerical control machine. Thus, the proposed algorithm is pre-processing the input image. The design feature of the laser engraver does not allow styling using an arbitrary style image, so dotted or linearized binary images are used as a style. The proposed preprocessing algorithm allows synthesizing binary images reproduced by a laser engraver. At the same time, image generation is performed in one forward pass of the generating neural network.

A Splicing Technique for Image Tampering using Morphological Operations

Image tampering is one part of the field of image editing or manipulation that changes certain parts of the graphic content of a given image. There are several techniques commonly used for image tampering, such as splicing, copy-move, retouching, etc. Splicing is a type of image tampering technique that combines two different images, replacing particular objects, skewing, rotation, etc. This study applies the splicing technique to image tampering using morphological operations. Morphology is a collection of image processing operations that process images based on their shape. The aim of this study is to replace particular objects in an original image with other objects that are similar to another selected image. In this study, we try to replace the ball object in the original image with another ball object from another image

A comparison of local features for camera-based document image retrieval and spotting

This paper aims at comparing robustness of local features for camera-based document image retrieval and spotting system. We present a literature review of the state of the art of local features extraction that includes keypoint detectors and keypoint descriptors. We also present a dataset and evaluation protocol for camera-based document image retrieval and spotting systems. This dataset is composed of three subparts: The first dataset represents the images with textual content only; the second dataset represents images with graphical content mainly; the third dataset contains text plus graphical elements. Along with the datasets, we present the protocol that describes measurements to evaluate the accuracy and processing time of camera-based document image retrieval and spotting systems. The latter is employed for presenting a detailed evaluation of local features from the literature.

Investigating the Impacts of Graphical Route Information Panel Layouts on Drivers’ Comprehension and Response Time

Graphical route information panels (GRIPs) are an alternative to conventional text-based variable message signs to address different traveler information needs. Since drivers are traveling at higher speeds on the motorways, they have to quickly comprehend and correctly respond to the graphical information displayed on a GRIP. Design elements like the shape of the route map, the meaning of colors indicating congestion and the font sizes of main and minor destinations along the route can influence the comprehension times of drivers. In this study, GRIPs with two purposes (congestion information and event destination information) were presented to 49 Belgian drivers in a computer-based task. All GRIPs were presented on an abstract and naturalistic motorway network shape. Half of the GRIPs were presented with congestion-related colors (red-only or red–orange), and the other half were presented with additional destinations being displayed in different or same font sizes to facilitate drivers visual search on the GRIP. Firstly, travel information statements were presented to the participant, followed by a displayed GRIP layout. Afterward, the participant had to indicate as fast as possible whether the subsequently shown GRIP confirmed the same travel statement. The subjects’ response accuracy and response times were recorded to assess drivers’ quick comprehension of the graphical content. The results of a repeated-measures ANOVA revealed that for GRIP displaying congestion, the red-color element (and not the map shape) significantly reduced drivers response times. A survey among participants also revealed a preference for two-color congestion information, if shown on an abstract map shape. An abstract map shape in combination with different font sizes for major and minor destinations improved drivers’ comprehension and response times to the GRIP, whereas different destination font sizes displayed on a naturalistic map had the contrary effect. The results highlight the importance of graphical design elements with respect to the information purpose.

A new work of the National Atlas of Spain called Spain on Maps. A Geographic Synopsis has been published

Abstract. The National Atlas of Spain is a compendium of maps, charts, reports, tables and photographs that aims to depict the detailed human and physical geography and history of Spain. This project began in 1880 and it is nowadays immersed in its fifth stage of life. The National Atlas of Spain of the 21st Century has been published in the year 2018 by the National Geographic Institute of Spain in cooperation with a scientific network of 38 institutions and 140 researchers and professors as well as 200 scientific experts. It is divided in 24 chapters and includes nearly 1200 graphic contents, 827 of which are maps. Data have been provided by over 125 national and international official organisations. This work may be obtained both on digital and paper formats on various conduits for information. New proposals and projects are also currently being carried out at the National Atlas of Spain, i.e. a new Geoportal has recently been published on the internet, chapter I.1.1. of the National Atlas has started being extended so that it may become a monograph, and a new Interactive Atlas is about to be published on the web. Other tasks for the coming months include keeping all resources updated on all conduits for information, translating the Atlas into English, improving the tool used for producing and publishing charts and transforming the product called the Atlas Thesaurus into an ontology so that all contents may be offered as semantic resources.

Taking Note: Challenges of Dealing with Graphical Content in TEI

This paper describes the ongoing development of a TEI-conformant model for the encoding of hybrid primary sources containing text and graphical components on a similar level of semantic meaning. The subsequent considerations are part of the digital scholarly edition project representing the notebooks of the Austrian conceptual artist Hartmut Skerbisch (1945–2009), a handwritten corpus created over a period of almost 40 years. Besides text, drawings were an important visual means of expression for the artist. In the context of digitally representing the numerous graphics embedded in the notes with equivalent depth to the text, a three-step model is proposed. This model takes into account the (1) graphical components characterizing the composition, (2) textual functions describing and directing the execution of artworks, and (3) interpretation of the graphics and their contextualization with connected material and information. The paper discusses the existing methods of representing graphics in TEI, presents the combination of these methods in the actual scholarly edition project, and introduces the semantic enrichment of the TEI sources through formal descriptions in RDF/XML taxonomies using linked open data. Thus, the genealogy of artistic concepts and artworks documented in the notebooks will become traceable.

Rape

Chinese avant-garde playwright Zhang Xian’s play Rape, initially completed in 2001, is a poignantly compelling postmodern drama on gender, politics, and power reversal situated in an imagined temporal and spatial setting. The play consists of a male character speaking throughout the play and a female character who remains mute and voiceless. From the man’s monologue, we come to realize that she seems to be Antigone in Sophocles’ play, while the man seems to be Creon, King of Thebes. In fact, the play is not the story of Antigone and Creon, but an abstract fable about politics in the East. These monologues of the male rapist contain strong language and large amounts of sexual content, which by themselves are figurative articulations in a political allegory. Reader discretion is strongly advised considering the play’s heavy graphic content, as well as the character’s provocative, ferocious, and potentially offensive expressions. The playwright Zhang Xian is aware that many of his plays, including this one, have not been staged in China because of his resistance against the institutional role of Chinese theater. He candidly observes his role to be that of “a special society performer—a dissident actor playing his unofficial part in China’s National Drama.” As a representation of Zhang’s work, Rape is forward-looking not only because of its productive new interpretations in the Chinese and global contexts of the #MeToo movement and feminist awakening, but also because of its ambition in projecting a distinctive anti-authoritarian political philosophy.

Graphicacy for Numeracy: Review of Fundamentals of Data Visualization: A Primer on Making Informative and Compelling Figures by Claus O. Wilke (2019)

Wilke, Claus O. 2019. Fundamentals of Data Visualization: A Primer on Making Informative and Compelling Figures. (Sebastopol, CA: O’Reilly Media, Inc.). 390 pp. ISBN 978-1-492-03108-6. First edition. First release: 03-15-2019.Claus O. Wilke has authored an excellent reference about producing and understanding static figures, figures used online, in print, and for presentations. His book is neither a statistics nor programming text, but familiarity with basic statistical concepts is helpful. Written in three parts, the book presents both the math and artistic design aspects of telling a story through figures. Wilke makes extensive use of examples, labels them good, bad, wrong or ugly, and explains why he deems them so. He includes chapters that serve as a directory of visualizations, and the reader will encounter familiar figure types as well as more esoteric ones. He discusses aesthetic considerations, including color, that make figures more compelling, and provides tips to connect with the audience to tell a story. Wilke intends the book for those producing figures, but consumers of graphical content will also find it helpful as his clear and concise style – and his effective use of examples – will help them evaluate the worth of figures they encounter.

Mockery as a tactic of destructive verbal communication in American political discourse

The aim of this paper is to analyze the communicative tactic of mockery in American political discourse. The problem of intensification of destructive elements in American political speech requires thorough investigation as political discourse becomes less conventional and more aggressive. In this context mockery is one of the general communicative tactics, which is used for humiliation and verbal assault on the speaker’s opponents. Mocking lets politicians destroy reputation of their competitors, presenting them in a negative way. Not only politicians, but also social, political and economic groups of people can become a target of mockery. The paper draws extensive empiric material to reveal that mockery is often used in pre-election discourse, because the goal of speakers in this kind of political discourse is to prevail over their opponents by all means. The communicative tactic of mockery may include destructive speech elements, e.g. invectives, negative epithets, dysphemism, pejoratives. This communicative tactic may be used along with special mimics, gestures or graphic content (caricature, video in media etc.). The analysis of empiric material proves that mockery rarely has unilateral character and frequently requires a response from the target. Users of this tactic demonstrate disrespect towards each other and try to impress and entertain their voters.

802-P: Text Messaging as a Behavioral Intervention Component for Adolescents and Young Adults with T1D

PREP-DC (Planning, Reflecting, and Engaging with Providers for Diabetes Care) is a multicomponent behavioral intervention aimed at promoting optimal health communication between adolescents and young adults (AYAs) with T1D and health care providers (HCPs). In the PREP-DC pilot, we examined engagement with text messaging and utilized AYA feedback to revise text messages for a randomized trial. AYAs with T1D>1 year (n=16; M age=18.8 years; 50% male; 44% Caucasian) participated in the pilot, consisting of 2 intervention sessions and 3 related text messages/week delivered between 2 T1D medical visits (∼16 weeks). The study team and an AYA stakeholder created a library of 72 text messages to reinforce T1D communication skills and self-care. Texts were sent via secure messaging platform. HCPs rated AYA communication at baseline and follow-up medical visits (∼16 weeks post-baseline) using the Independent Behaviors during Consultation Scale (IBDCS). A1c was taken from the medical chart. Participants received a mean of 45 texts. One text/week posed a question and encouraged AYA response (M=15.5 texts); 69% responded ≥1 text (M responses=4±4.2 texts). Intervention outcomes differed by text response. AYAs with no responses had worsening A1c (10.4% to 11.2%; p<.05) and stable HCP-rated communication (IBDCS; 20.8 to 20.0; p=ns) from baseline to follow-up. AYAs with ≥ 1 response had stable A1c (9.6% to 9.6%; p=ns) and improved HCP-rated communication (IBDCS; 19.6 to 24.9; p<.01) from baseline to follow-up. AYAs reported high satisfaction with text messages. Feedback was used to revise text messages, including new response prompts, graphic content (e.g., memes), and more message tailoring. Text messaging was a promising component of this intervention pilot, and an indicator of text message engagement was related to intervention response. Future studies should further examine engagement with text messages, including analytics on opening texts and message content associated with higher AYA response. Disclosure M.

Using Syndromic Surveillance Data to Study the Impact of Media Content on Self-harm

Using Syndromic Surveillance Data to Study the Impact of Media Content on Self-harm

Figure and caption extraction from biomedical documents.

MotivationFigures and captions convey essential information in biomedical documents. As such, there is a growing interest in mining published biomedical figures and in utilizing their respective captions as a source of knowledge. Notably, an essential step underlying such mining is the extraction of figures and captions from publications. While several PDF parsing tools that extract information from such documents are publicly available, they attempt to identify images by analyzing the PDF encoding and structure and the complex graphical objects embedded within. As such, they often incorrectly identify figures and captions in scientific publications, whose structure is often non-trivial. The extraction of figures, captions and figure-caption pairs from biomedical publications is thus neither well-studied nor yet well-addressed.ResultsWe introduce a new and effective system for figure and caption extraction, PDFigCapX. Unlike existing methods, we first separate between text and graphical contents, and then utilize layout information to effectively detect and extract figures and captions. We generate files containing the figures and their associated captions and provide those as output to the end-user.We test our system both over a public dataset of computer science documents previously used by others, and over two newly collected sets of publications focusing on the biomedical domain. Our experiments and results comparing PDFigCapX to other state-of-the-art systems show a significant improvement in performance, and demonstrate the effectiveness and robustness of our approach.Availability and implementationOur system is publicly available for use at: https://www.eecis.udel.edu/~compbio/PDFigCapX. The two new datasets are available at: https://www.eecis.udel.edu/~compbio/PDFigCapX/Downloads

Fanzine – arquitetura e revolução

Apoiado na metodologia aplicada na disciplina de Teoria e História da Arquitetura e Urbanismo IV, ministrada pelo professor Ricardo Rocha, com base em parte de seu conteúdo programático que abordava a organização do ambiente construído decorrente da Revolução Industrial até a Primeira Guerra Mundial, foi desenvolvido um fanzine - revista de cunho alternativo e não-convencional de apresentação de conteúdo - como exercício avaliativo da matéria para exposição do conhecimento produzido. Sob o título de “Arquitetura e Revolução”, o fanzine retrata a relação entre momentos históricos e a arquitetura, especificamente sobre as Revoluções Francesa e Russa e os estilos arquitetônicos Neoclássico e Construtivista. O material produzido busca através de sua organização gráfica e visual promover a reflexão sobre as ocorrências e mudanças sociais de cada período e seu reflexo no meio arquitetônico, empregando entre suas páginas o contraste das características peculiares de cada movimento. Como referência para desenvolvimento do conteúdo gráfico, foram utilizados cartazes políticos do século XX, que apresentam uma linguagem visual expressiva e inovadora em relação aos materiais dos quais se produziam até então, principalmente os cartazes russos, que antes tinham como base panfletos franceses e passam a ter uma linguagem própria, utilizada como meio de persuasão política.
