General Consumer Communication Tools for Improved Image Management and Communication in Medicine

We elected to explore new technologies emerging on the general consumer market that can improve and facilitate image and data communication in medical and clinical environment. These new technologies developed for communication and storage of data can improve the user convenience and facilitate the communication and transport of images and related data beyond the usual limits and restrictions of a traditional picture archiving and communication systems (PACS) network. We specifically tested and implemented three new technologies provided on Apple computer platforms. (1) We adopted the iPod, a MP3 portable player with a hard disk storage, to easily and quickly move large number of DICOM images. (2) We adopted iChat, a videoconference and instant-messaging software, to transmit DICOM images in real time to a distant computer for conferencing teleradiology. (3) Finally, we developed a direct secure interface to use the iDisk service, a file-sharing service based on the WebDAV technology, to send and share DICOM files between distant computers. These three technologies were integrated in a new open-source image navigation and display software called OsiriX allowing for manipulation and communication of multimodality and multidimensional DICOM image data sets. This software is freely available as an open-source project at http://homepage.mac.com/rossetantoine/OsiriX. Our experience showed that the implementation of these technologies allowed us to significantly enhance the existing PACS with valuable new features without any additional investment or the need for complex extensions of our infrastructure. The added features such as teleradiology, secure and convenient image and data communication, and the use of external data storage services open the gate to a much broader extension of our imaging infrastructure to the outside worl

Evaluating a Web-Based Interface for Internet Telemedicine

The objective is to introduce the usability engineering methodology, heuristic evaluation, to the design and development of a web-based telemedicine system. Using a set of usability criteria, or heuristics, one evaluator examined the Spacebridge to Russia web-site for usability problems. Thirty-four usability problems were found in this preliminary study and all were assigned a severity rating. The value of heuristic analysis in the iterative design of a system is shown because the problems can be fixed before deployment of a system and the problems are of a different nature than those found by actual users of the system. It was therefore determined that there is potential value of heuristic evaluation paired with user testing as a strategy for optimal system performance design

Television Production : Managing the Technology

The idea to write the thesis about television production came into my mind a long time ago. I knew that this area of media technology was the most interesting for me. I had an internship in Aito Media Oy television production company in 2009, and I studied TV Production at Ferris State University, USA for one academic year 2010-2011. The main objective for my thesis is to research, compare and describe all steps in production of a television show from the developing an idea through planning, budgeting, shooting and editing to the final release of the TV show on the screen. Also I would like to observe the technologies used nowadays and determine the role of a producer in the TV production. To reach my objective, I read several books and electronical materials on different topics about phases of the production, equipment and techniques, communication and documentation. Furthermore, I use knowledge from my own experience, which I got while studying and making practical tasks at Television and Digital Media Production program at Ferris State University. I learned the professional skills required in all aspects of different phases of television production, including studio workflow, camera operation, field equipment, multicamera directing and the responsibilities and organ-izational expertise of the producer. At the same time, I explored the latest production techniques and technology, such as audio and lighting work-stations, non-linear editing, high-definition television and 3D television.Ajatus tehdä opinnäytetyöni televisiotuotannosta tuli jo kauan sitten, koska tiesin, että se on henkilökohtaisesti mielenkiintoisin alue mediatekniikassa. Olin työharjoittelussa Aito Media Oy tv-tuotantoyhtiössä vuonna 2009, ja lukuvuodessa 2010-2011 opiskelin Ferris State University:n TV-tuotanto ja Digimedian koulutusohjelmassa, Yhdysvaltoissa. Työn päätavoitteena on tutkia, vertailla ja kuvata kaikki tv-ohjelman tuotannon vaiheet alkaen idean kehittämisestä, sekä suunnittelun, budjetoinnin, kuvausten ja editoinnin kautta lopullisen tv-ohjelman version julkaistamiseen. Myöskin haluan havainnoida nykyaikaisia tekniikoita ja määrittää tuottajan roolin tv-tuotannossa. Tavoiteeni saavuttakseni olen lukenut useita kirjoja ja elektronisia lähteitä erilaisilla aiheilla, kuten tv tuotannon vaiheet, laitteisto ja tekniikat, viestintä ja dokumentointi. Lisäksi käytän tietoja omasta kokemuksestani, mitkä sain kun opiskelin Ferris State University:ssa ja tein erilaisia tv tuotannon liittyviä tehtäviä. Olen oppinut tarvittavaa ammattitaitoa kaikilla tv-tuotannon vaiheilla, kuten työnkulku studiossa, cameran operointi, tuotantolaitteiden käyttö kentällä, monicameroiden ohjaus sekä tuottajan vastuut ja järjestelytaidot. Samalla tutkin viimeisimpiä tuotantomenetelmiä ja tekniikkaa, kuten ääni- ja valaistustyöasemien käyttöä, käytössä olevia editointiohjelmistoja ja teräväpiirtotelevision ja 3D television ominaisuuksia

Video interaction using pen-based technology

Dissertação para obtenção do Grau de Doutor em InformáticaVideo can be considered one of the most complete and complex media and its manipulating is still a difficult and tedious task. This research applies pen-based technology to video manipulation, with the goal to improve this interaction. Even though the human familiarity with pen-based devices, how they can be used on video interaction, in order to improve it, making it more natural and at the same time fostering the user’s creativity is an open question. Two types of interaction with video were considered in this work: video annotation and video editing. Each interaction type allows the study of one of the interaction modes of using pen-based technology: indirectly, through digital ink, or directly, trough pen gestures or pressure. This research contributes with two approaches for pen-based video interaction: pen-based video annotations and video as ink. The first uses pen-based annotations combined with motion tracking algorithms, in order to augment video content with sketches or handwritten notes. It aims to study how pen-based technology can be used to annotate a moving objects and how to maintain the association between a pen-based annotations and the annotated moving object The second concept replaces digital ink by video content, studding how pen gestures and pressure can be used on video editing and what kind of changes are needed in the interface, in order to provide a more familiar and creative interaction in this usage context.This work was partially funded by the UTAustin-Portugal, Digital Media, Program (Ph.D. grant: SFRH/BD/42662/2007 - FCT/MCTES); by the HP Technology for Teaching Grant Initiative 2006; by the project "TKB - A Transmedia Knowledge Base for contemporary dance" (PTDC/EAT/AVP/098220/2008 funded by FCT/MCTES); and by CITI/DI/FCT/UNL (PEst-OE/EEI/UI0527/2011

Co-present photo sharing on mobile devices

This dissertation researches current approaches to photo sharing. We have found that most current methods of photo sharing are not as compelling as traditional photo sharing - with the increasing in popularity of digital photography, consumers do not print photos as often as before and thus typically require a group display (such as a PC) to view their photographs collectively. This dissertation describes a mobile application that attempts to support traditional photo sharing activities by allowing users to share photos with other co-present users by synchronizing the display on multiple mobile devices. Various floor control policies (software locks that determine when someone can control the displays) were implemented. The behaviour of groups of users was studied to determine how people would use this application for sharing photos and how various floor control policies affect this behaviour

Towards a Practitioner Model of Mobile Music

This practice-based research investigates the mobile paradigm in the context of electronic music, sound and performance; it considers the idea of mobile as a lens through which a new model of electronic music performance can be interrogated. This research explores mobile media devices as tools and modes of artistic expression in everyday contexts and situations. While many of the previous studies have tended to focus upon the design and construction of new hardware and software systems, this research puts performance practice at the centre of its analysis. This research builds a methodological and practical framework that draws upon theories of mobile-mediated aurality, rhetoric on the practice of walking, relational aesthetics, and urban and natural environments as sites for musical performance. The aim is to question the spaces commonly associated with electronic music – where it is situated, listened to and experienced. This thesis concentrates on the creative use of existing systems using generic mobile devices – smartphones, tablets and HD cameras – and commercially available apps. It will describe the development, implementation and evaluation of a self-contained performance system utilising digital signal processing apps and the interconnectivity of an inter-app routing system. This is an area of investigation that other research programmes have not addressed in any depth. This research’s enquiries will be held in dynamic and often unpredictable conditions, from navigating busy streets to the fold down shelf on the back of a train seat, as a solo performer or larger groups of players, working with musicians, nonmusicians and other participants. Along the way, it examines how ubiquitous mobile technology and its total access might promote inclusivity and creativity through the cultural adhesive of mobile media. This research aims to explore how being mobile has unrealised potential to change the methods and experiences of making electronic music, to generate a new kind of performer identity and as a consequence lead towards a practitioner model of mobile music
