Deep Neural Network and Data Augmentation Methodology for off-axis iris segmentation in wearable headsets
A data augmentation methodology is presented and applied to generate a large
dataset of off-axis iris regions and train a low-complexity deep neural
network. Although of low complexity the resulting network achieves a high level
of accuracy in iris region segmentation for challenging off-axis eye-patches.
Interestingly, this network is also shown to achieve high levels of performance
for regular, frontal, segmentation of iris regions, comparing favorably with
state-of-the-art techniques of significantly higher complexity. Due to its
lower complexity, this network is well suited for deployment in embedded
applications such as augmented and mixed reality headsets
Designing mobile augmented reality art applications:addressing the views of the galleries and the artists
The utilization of mobile augmented reality to display gallery artworks or museum content in novel ways is a well-established concept in the augmented reality research community. However, the focus of these systems is generally technologically driven or only addresses the end user and not the views of the gallery or the original artist. In this paper we discuss the design and development of the mobile application ?Taking the Artwork Home?, which allows people to digitally curate their own augmented reality art exhibitions in their own homes by digitally ?replacing? the pictures they have on their walls with content from the Peter Scott Gallery in Lancaster. In particular, we present the insights gained from a research through design methodology that allowed us to consider how the views of the gallery and artists impacted on the system design and therefore the user experience. Thus the final artifact is the result of an iterative evaluation process with over 100 users representing a broad range of demographics and continues to be evaluated/enhanced by observing its operation ?in the wild?. Further, we consider the effect the project has had on gallery practices to enable both augmented reality designers, and galleries and museums to maximize the potential application of the technology when working together on such project

Superar el límite de la pantalla:el futuro integrado del diseño industrial e innovación de la interfaz
Tesis inédita de la Universidad Complutense de Madrid, Facultad de Bellas Artes, leída el 27-11-2019The goals of this thesis are to streamline the design process of CDDs for both theirhardware and software, simplify the process of their conception, creation andproduction, motivate the design and interactive innovations for the next generationof CDDs.Starting with the process of investigating the design history of CDDs, we noticed theincreasing bi-directional influence between the graphical interface design and theindustrial design of these products. We started to work on the hypothesis:“A connection point between classical industrial design theories and moderninnovations in the world of interface design can be found, and the future of CDDrequires a universal design system for both its hardware and software.”In order to put our hypothesis into practice, it is important to clarify the generic andspecific objectives...El fin de esta tesis es mejorar el proceso de diseño de DDC tanto para su hardware como para su software, simplificar el proceso de concepción, creación y producción,así como motivar el diseño y las innovaciones interactivas para la próxima generación de DDC. Comenzando con un proceso de investigación que respete la historia del diseño de los DDC, notamos un incremento en la influencia bidireccional entre el diseño de interfaz gráfica y el diseño industrial de estos productos. Trabajamos sobre esta hipótesis: “Se puede encontrar un punto de conexión entre las teorías clásicas de diseño industrial y las innovaciones modernas en el mundo del diseño de interfaz. El futuro de los DDC requiere un sistema de diseño unificado para ambos: hardware y software.”Para poner nuestra hipótesis en práctica, es importante aclarar los objetivos genéricos y específicos...Fac. de Bellas ArtesTRUEunpu

Augmented reality and its aspects: a case study for heating systems
Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do ParanáThanks to the advances of technology in various domains, and the mixing between real
and virtual worlds. Allowed this master’s thesis to explore concepts related to virtual
reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR).
The development and comparison of Android applications and Microsoft HoloLens
aimed to solve a deadlock in the recognition of instructions by the users. We used an
interactive manual of assembly and disassembly for taps of residential heaters.
Therefore, this work deals with three main parts. Firstly, the exploration of the
concepts of VR, AR, MR, and XR. Secondly, 3D modeling and animations techniques.
Finally, the development of applications using Vuforia, Wikitude, and MRTK.
The users tried our application “HeaterGuideAR” to verify the effectiveness of the
instruction passed by the interactive manual. Only a few users had some difficulties
at the beginning of the trials. Thus, it was necessary to provide aid tools. However,
other users were able to disassemble the faucet without any external help. We suggest
continuing this work with more explorations, models, and situations.Graças aos últimos avanços tecnológicos em diversas áreas deram a possibilidade de fazer
a mistura do mundo real com o virtual. É com este intuito que esta tese de mestrado
veio expor os conceitos relacionados à realidade virtual (RV), realidade aumentada (RA),
realidade mista (RM) e realidade estendida (RE).
O desenvolvimento e comparação de aplicativos Android e Microsoft HoloLens teve
como objetivo resolver um impasse no entendimento de instruções por parte dos usuários.
Utilizamos um manual interativo para montagem e desmontagem de torneiras de aquecedores
residenciais.
Este trabalho, portanto, lida com três partes principais. Na primeira, a exploração
dos conceitos de RV, RA, RM e RE. Na segunda, modelagem 3D e técnicas de animações.
E por fim, o desenvolvimento de aplicações usando Vuforia, Wikitude e MRTK.
A aplicação “HeaterGuideAR” foi testada pelos usuários afim de verificar a eficácia
da instrução passada pelo manual interativo. Apenas alguns usuários tiveram algumas
dificuldades no início dos testes. Sendo que, foi necessário fornecer algumas ferramentas
de auxílio. Mesmo assim, outros usuários conseguiram desmontar a torneira sem ajuda
externa. Sugerimos continuar este trabalho com mais explorações, modelos e situações.Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do Paran
Augmented reality over maps
Dissertação de mestrado integrado em Engenharia InformáticaMaps and Geographic Information System (GIS) play a major role in modern society,
particularly on tourism, navigation and personal guidance. However, providing geographical
information of interest related to individual queries remains a strenuous task. The main
constraints are (1) the several information scales available, (2) the large amount of information
available on each scale, and (3) difficulty in directly infer a meaningful geographical context
from text, pictures, or diagrams that are used by most user-aiding systems. To that extent,
and to overcome the aforementioned difficulties, we develop a solution which allows the
overlap of visual information over the maps being queried — a method commonly referred
to as Augmented Reality (AR).
With that in mind, the object of this dissertation is the research and implementation of a
method for the delivery of visual cartographic information over physical (analogue) and
digital two-dimensional (2D) maps utilizing AR. We review existing state-of-art solutions and
outline their limitations across different use cases. Afterwards, we provide a generic modular
solution for a multitude of real-life applications, to name a few: museums, fairs, expositions,
and public street maps. During the development phase, we take into consideration the
trade-off between speed and accuracy in order to develop an accurate and real-time solution.
Finally, we demonstrate the feasibility of our methods with an application on a real use case
based on a map of the city of Oporto, in Portugal.Mapas e Sistema de Informação Geográfica (GIS) desempenham um papel importante na
sociedade, particularmente no turismo, navegação e orientação pessoal. No entanto, fornecer
informações geográficas de interesse a consultas dos utilizadores é uma tarefa árdua. Os
principais dificuldades são (1) as várias escalas de informações disponíveis, (2) a grande
quantidade de informação disponível em cada escala e (3) dificuldade em inferir diretamente
um contexto geográfico significativo a partir dos textos, figuras ou diagramas usados. Assim,
e para superar as dificuldades mencionadas, desenvolvemos uma solução que permite a
sobreposição de informações visuais sobre os mapas que estão a ser consultados - um
método geralmente conhecido como Realidade Aumentada (AR).
Neste sentido, o objetivo desta dissertação é a pesquisa e implementação de um método para
a visualização de informações cartográficas sobre mapas 2D físicos (analógicos) e digitais
utilizando AR. Em primeiro lugar, analisamos o estado da arte juntamente com as soluções
existentes e também as suas limitações nas diversas utilizações possíveis. Posteriormente,
fornecemos uma solução modular genérica para uma várias aplicações reais tais como:
museus, feiras, exposições e mapas públicos de ruas. Durante a fase de desenvolvimento,
tivemos em consideração o compromisso entre velocidade e precisão, a fim de desenvolver
uma solução precisa que funciona em tempo real. Por fim, demonstramos a viabilidade de
nossos métodos com uma aplicação num caso de uso real baseado num mapa da cidade do
Porto (Portugal)
