No. of bitstreams: 1 Albert Florencio da Costa.pdf: 7724360 bytes, checksum: c3561856ecba1bc5c6aac8e554df15b8 (MD5) Previous issue date: 2017-05-02 / This study presents an analysis of friendly interfaces for Internet systems, which facilitates the use of commercial consultants (non-technical) in creating digital business. The objective of this study is to verify the importance of friendly digital platforms so that lay commercial consultants are not eliminated from the market, in the current environment where digital businesses are growing every day. Through a bibliographic review, presenting the current scenario in which the commercial consultants beds are inserted, as well as the technical requirements necessary to build a good interface, we analyze the use of the Interface (OnCorretor) offered by the company Porto Seguro to its Insurance Brokers Who are the commercial consultants of this market. We conclude that the OnCorretor is a platform that meets the brokers business expectations, accessible including being by lay users, allowing them to build their own websites with your domain, manage email accounts, manage online proposals, interact with their customers. The OnCorretor platform has a user-friendly interface that makes it easy to use, but some users still have questions about how to get the best results in their business. In this way, we suggest that an online training, as well as a greater use of interaction with social networks, be made available to the user whenever he needs it. We also suggest periodic surveys for the maintenance and optimization of your business, with presence on the Internet and on social networks. The most important finding is that the user-friendly interface is simple to use for 75.6% of respondent brokers and 63.2% of them understand that it has helped to optimize their business. We suggest that other companies in the insurance industry or other using consultants commercial to develop similar platforms based on this model / Este estudo apresenta uma análise das interfaces amigáveis para sistemas de Internet, que facilitem o uso para Consultores comerciais leigos (não-técnicos) na realização de negócios digitais. O Objetivo desse estudo é verificar a importância de plataformas digitais amigáveis para que consultores comerciais leigos não sejam eliminados do mercado, na atual conjuntura onde os negócios digitais vêm crescendo a cada dia. Através de uma revisão bibliográfica, apresentando o cenário atual em que os Consultores Comerciais leigos estão inseridos, bem como os requisitos técnicos necessários para construção de uma boa interface, analisamos o uso da Interface (OnCorretor) oferecida pela empresa Porto Seguro a seus Corretores de Seguro que são os Consultores comerciais desse mercado. Concluímos que o OnCorretor é uma plataforma que atende às expectativas de negócios dos corretores, sendo acessível inclusive por usuários leigos, permitindo que eles possam construir seus próprios sites, com seu domínio, gerenciar contas de email, gerenciar propostas online, interagir com seus clientes. A plataforma OnCorretor possui uma interface amigável que facilita a sua utilização, mas, alguns usuários ainda têm dúvidas sobre como obter os melhores resultados em seus negócios. Deste modo, sugerimos que seja disponibilizado um treinamento online, bem como uma utilização maior de interação com redes sociais, que seja acessível ao usuário sempre que ele precisar. Sugerimos também pesquisas periódicas para a manutenção e otimização de seu negócio, com presença na Internet e nas redes sociais. A mais importante constatação é que a interface amigável é simples de ser usada para 75,6% dos corretores respondentes e que 63.2% deles entendem que ela ajudou a otimizar seus negócios. Sugerimos que outras empresas do setor de seguros ou outras que utilizem Consultores Comerciais que desenvolvam plataformas similares baseadas nesse modelo

Em computação ubíqua, existe a ideia de tornar o computador onipresente, \"invisível\", de modo a aproximar computadores e humanos. Com o avanço das tecnologias de hardware e de software, torna-se interessante investigar possibilidades inovadoras de interação com os computadores. Neste trabalho, exploramos novas formas de interação inspiradas nos atos de desenhar, agarrar e gesticular. Para testá-las, desenvolvemos novos algoritmos baseados em câmeras RGBD para detecção, classificação e rastreamento de objetos, o que permite a concepção de uma instalação interativa que utilize equipamentos portáteis e de baixo custo. Para avaliar as formas de interação propostas, desenvolvemos a Superfície Mágica, um sistema que transforma uma superfície comum (como uma parede ou uma mesa) num espaço interativo multi-toque. A Superfície Mágica identifica toques de dedos de mãos, de canetas coloridas e de um apagador, oferecendo também suporte a uma varinha mágica para interação 3D. A Superfície Mágica suporta a execução de aplicativos, permitindo que uma superfície comum se transforme numa área interativa para desenho, num explorador de mapas, num simulador 3D para navegação em ambientes virtuais, entre outras possibilidades. As áreas de aplicação do sistema vão desde a educação até a arte interativa e o entretenimento. A instalação do protótipo envolve: um sensor Microsoft Kinect, um projetor de vídeo e um computador pessoal. / Ubiquitous computing is a concept where computing is thought to be omnipresent, effectively \"invisible\", so that humans and computers are brought together in a seamless way. The progress of hardware and software technologies make it compelling to investigate innovative possibilities of interaction with computers. In this work, we explore novel ways of interaction that are inspired by the acts of drawing, grasping and gesturing. In order to test them, we have developed new RGBD camera-based algorithms for object detection, classification and tracking. This allows the conception of an interactive installation that uses portable and low cost equipment. In order to evaluate the proposed ways of interaction, we have developed the Magic Surface, a system that transforms a regular surface (such as a wall or a tabletop) into a multitouch interactive space. The Magic Surface detects touch of hand fingers, colored pens and eraser. It also supports the usage of a magic wand for 3D interaction. The Magic Surface can run applications, allowing the transformation of a regular surface into an interactive drawing area, a map explorer, a 3D simulator for navigation in virtual environments, among other possibilities. Areas of application range from education to interactive art and entertainment. The setup of our prototype includes: a Microsoft Kinect sensor, a video projector and a personal computer.

Les logiciels de patching audio traditionnels, tels que Max ou Pure Data, sont des environnements qui permettent de concevoir et d’exécuter des traitements sonores en temps réel. Ces logiciels sont mono-utilisateurs, or, dans bien des cas, les utilisateurs ont besoin de travailler en étroite collaboration à l’élaboration ou à l’exécution d’un même traitement. C’est notamment le cas dans un contexte pédagogique ainsi que pour la création musicale collective. Des solutions existent, mais ne conviennent pas forcément à tous les usages. Aussi avons-nous cherché à nous confronter de manière concrète à cette problématique en développant une nouvelle solution de patching audio collaborative, baptisée Kiwi, qui permet l’élaboration d’un même traitement sonore à plusieurs mains de manière distribuée. À travers une étude critique des solutions logicielles existantes nous donnons des clefs de compréhension pour appréhender la conception d’un système multi-utilisateur de ce type. Nous énonçons les principaux verrous que nous avons eu à lever pour rendre cette pratique viable et présentons la solution logicielle. Nous exposons les possibilités offertes par l’application et les choix de mise en œuvre techniques et ergonomiques que nous avons faits pour permettre à plusieurs personnes de coordonner leurs activités au sein d’un espace de travail mis en commun. Nous revenons ensuite sur différents cas d’utilisation de ce collecticiel dans un contexte pédagogique et de création musicale afin d’évaluer la solution proposée. Nous exposons enfin les développements plus récents et ouvrons sur les perspectives futures que cette application nous permet d’envisager. / Traditional audio patching software, such as Max or Pure Data, are environments that allow you to design and execute sound processing in real time. These programs are single-user, but, in many cases, users need to work together and in a tight way to create and play the same sound processing. This is particularly the case in a pedagogical context and for collective musical creation. Solutions exist, but are not necessarily suitable for all uses. We have tried to confront this problem in a concrete way by developing a new collaborative audio patching solution, named Kiwi, which allows the design of a sound processing with several hands in a distributed manner. Through a critical study of the existing software solutions we give keys of comprehension to apprehend the design of a multi-user system of this type. We present the main barriers that we had to lift to make this practice viable and present the software solution. We show the possibilities offered by the application and the technical and ergonomic implementation choices that we have made to allow several people to coordinate their activities within a shared workspace. Then, we study several uses of this groupware in pedagogical and musical creation contexts in order to evaluate the proposed solution. Finally, we present the recent developments and open up new perspectives for the application.

Multimodal communication is key to smooth interactions between people. However, multimodality remains limited in current human-computer interfaces. For example, posture is less explored than other modalities, such as speech and facial expressions. The postural expressions of others have a huge impact on how we situate and interpret an interaction. Devices and interfaces for representing full-body interaction are available (e.g., Kinect and full-body avatars), but systems still lack computational models relating these modalities to spatial and emotional communicative functions.The goal of this thesis is to lay the foundation for computational models that enable better use of posture in human-computer interaction. This necessitates addressing several research questions: How can we symbolically represent postures used in interpersonal communication? How can these representations inform the design of virtual characters' postural expressions? What are the requirements of a model of postural interaction for application to interactive virtual characters? How can this model be applied in different spatial and social contexts?In our approach, we start with the manual annotation of video corpora featuring postural expressions. We define a coding scheme for the manual annotation of posture at several levels of abstraction and for different body parts. These representations were used for analyzing the spatial and temporal relations between postures displayed by two human interlocutors during spontaneous conversations.Next, representations were used to inform the design of postural expressions displayed by virtual characters. For studying postural expressions, we selected one promising, relevant component of emotions: the action tendency. Animations were designed featuring action tendencies in a female character. These animations were used as a social context in perception tests.Finally, postural expressions were designed for a virtual character used in an ambient interaction system. These postural and spatial behaviors were used to help users locate real objects in an intelligent room (iRoom). The impact of these bodily expressions on the user¡¯s performance, subjective perception and behavior was evaluated in a user studyFurther studies of bodily interaction are called for involving, for example, motion-capture techniques, integration with other spatial modalities such as gaze, and consideration of individual differences in bodily interaction.

Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location, an approach that is useful across many disciplines. However, spatiotemporal data structures can be quite complex, and the datasets very large. Although GIS software programs are capable of processing and analyzing spatial information, most contain no (or minimal) features for handling temporal information and have limited capability to deal with large, complex multidimensional spatiotemporal data. A related problem is how to best represent spatiotemporal data to support efficient processing, analysis, and visualization. In the era of "big data," efficient methods for analyzing and visualizing large quantities of spatiotemporal data have become increasingly necessary. Automated processing approaches, when made scalable and generalizable, can result in much greater efficiency in spatiotemporal data analysis. The growing popularity of web services and server-side processing methods can be leveraged to create systems for processing spatiotemporal data on the server, with delivery of output products to the client. In many cases, the client can be a standard web browser, providing a common platform from which users can interact with complex server-side processing systems to produce specific output data and visualizations. The rise of complex JavaScript libraries for creating interactive client-side tools has enabled the development of rich internet applications (RIA) that provide interactive data exploration capabilities and an enhanced user experience within the web browser. Three projects involving time-series tsunami simulation data, potential human response in a tsunami evacuation scenario, and large sets of modeled time-series climate grids were conducted to explore automated web-based analysis, processing, and visualization of spatiotemporal data. Methods were developed for efficient handling of spatiotemporal data on the server side, as well as for interactive animation and visualization tools on the client side. The common web browser, particularly when combined with specialized server side code and client side RIA libraries, was found to be an effective platform for analysis and visualization tools that quickly interact with complex spatiotemporal data. Although specialized methods were developed to for each project, in most cases those methods can be generalized to other disciplines or computational domains where similar problem sets exist. / Graduation date: 2013

This paper examines the results of a usability study for finding aids from the Special Collections Research Center at North Carolina State University. In 2005, the Special Collections Research Center reformatted its finding aids so that the container information, typically located on the left-hand side of the document, moved to the right-hand side of the document. The study tested the effectiveness of this change, and determined that traditional finding aids performed better. The analysis of the study’s results is followed by a discussion about Web usability guidelines for online finding aids.

This research investigated the Mission Specialist role in micro unmanned aerial systems (mUAS) and was informed by human-robot interaction (HRI) and technology findings, resulting in the design of an interface that increased the individual performance of 26 untrained CBRN (chemical, biological, radiological, nuclear) responders during two field studies, and yielded formative observations for HRI in mUAS. Findings from the HRI literature suggested a Mission Specialist requires a role-specific interface that shares visual common ground with the Pilot role and allows active control of the unmanned aerial vehicle (UAV) payload camera. Current interaction technology prohibits this as responders view the same interface as the Pilot and give verbal directions for navigation and payload control. A review of interaction principles resulted in a synthesis of five design guidelines and a system architecture that were used to implement a Mission Specialist interface on an Apple iPad. The Shared Roles Model was used to model the mUAS human-robot team using three formal role descriptions synthesized from the literature (Flight Director, Pilot, and Mission Specialist). The Mission Specialist interface was evaluated through two separate field studies involving 26 CBRN experts who did not have mUAS experience. The studies consisted of 52 mission trials to surveil, evaluate, and capture imagery of a chemical train derailment incident staged at Disaster City. Results from the experimental study showed that when a Mission Specialist was able to actively control the UAV payload camera and verbally coordinate with the Pilot, greater role empowerment (confidence, comfort, and perceived best individual and team performance) was reported by a majority of participants for similar tasks; thus, a role-specific interface is preferred and should be used by untrained responders instead of viewing the same interface as the Pilot in mUAS. Formative observations made during this research suggested: i) establishing common ground in mUAS is both verbal and visual, ii) type of coordination (active or passive) preferred by the Mission Specialist is affected by command-level experience and perceived responsibility for the robot, and iii) a separate Pilot role is necessary regardless of preferred coordination type in mUAS. This research is of importance to HRI and CBRN researchers and practitioners, as well as those in the fields of robotics, human-computer interaction, and artificial intelligence, because it found that a human Pilot role is necessary for assistance and understanding, and that there are hidden dependencies in the human-robot team that affect Mission Specialist performance.
