Since this provides the ability to manipulate the physical reality remotely in real time, through its virtual representation. Through the technology of virtual reality, one can create a wide variety of environments suitable for all kinds of applications, enabling simulations of the situations in a real world environment or virtual world. The application of virtual environments in the manufacturing process is related to both the maintenance and training, and also the creation and simulation of virtual prototypes before their use in the shop-floor. The use of Petri nets for modeling virtual environments, shows itself as a powerful graphics/mathematics tool that can capture the main features of virtual reality systems, as well as offering interesting empirical results in automatic verification of concurrence and real time systems. By allowing to model non-deterministic and parallel computation, modeling of virtual environments with Petri nets is appropriate not only for simulation, verification and validation of these systems, but also for controlling the environments modeled. By associating the elements of a Petri net with the elements of the object oriented paradigm of a set of classes that are the objects that will compose the virtual environments and telepresence systems, one gets a valuable tool for controlling of the methods of virtual and real objects to be invoked. The objective of this work is the development of the mode of association of Petri nets with virtual and real objects for controlling immersive virtual environments and telepresence, based on the description of a telepresence authoring system controlled by PN. The results will bring progress on the development and deployment of virtual manufacturing applications in an immersive 3D visualization environment.

This exploratory research used a mixed-methods design to compare the effectiveness of a telepresence-enabled cognitive apprenticeship model of teacher professional development (TEAM-PD) to that of a traditional workshop model by examining outcomes in teacher pedagogy and student achievement. Measures of the lll degree to which teachers in both groups enacted mathematics pedagogy provided mixed results. Both groups demonstrated similar patterns of behavior and cognition, indicating modest levels of pedagogy implementation. Although the experimental group demonstrated higher levels of enactment of the mathematics pedagogy, the comparison group demonstrated a faster rate of growth. Student outcome data were clear: students of teachers in the experimental group scored substantially higher on a test of relevant mathematics content than students of teachers in the comparison group. Collectively the results suggest that TEAM-PD has potential to be an effective model of teacher professional development.

Den här studien har undersökt möjligheten att implementera tekniken telepresence för att låta funktionshindrade uppleva svåråtkomliga platser. De svenska hälsingegårdarna kan i många fall klassas som en svåråtkomlig plats då de har höga trösklar, branta trappor, smala dörrar mm. Eftersom en del av gårdarna är klassificerade som världsarv går det inte att tillgänglighetsanpassa byggnaderna då de måste bevaras i deras befintliga skick. Begränsad framkomlighet som leder till att inte alla personer kan besöka platsen kan vara diskriminerande då ett kulturarv ska hållas tillgängligt för allmänheten. Genom att kombinera olika tekniska lösningar har det här arbetet undersökt hur telepresence kan implementeras för att hjälpa personer med rörelsehinder att uppleva hälsingegårdarna.Olika produkter som förekommer i handeln har testats och en prototyp har tagits fram. Resultatet är ett “proof of concept” som visar att VR headset tillsammans med telepresence kan tillämpas för att låta en användare uppleva dessa gårdar i realtid.

Mobile media are quickly becoming primary sources of communication in everyday life. With this progress, comes the ability to experience an array of different degrees and types of presence. Individuals can be both in the physical presence of others as well as present with others at a distance by experiencing telepresence. This study examined the role of mobile media in the context of romantic relationships. It looked at the relationship between the senses of intimacy and telepresence as they were experienced by individuals. The theories of apparatgeist and perpetual contact were employed to describe the relationship between the nature of the technology, the associated behavior of its use, and the experience of various forms of telepresence. Interviews with fourteen participants provided the data analyzed in this qualitative study. These interviews were transcribed and used for a thematic analysis of presence and intimacy experience. The results describe a wide variance and nuanced reality of how individuals sense the presence of each other through mobile technology. These results contribute to an understanding of how individuals understand and talk about their experience of telepresence and also what it means to them in their personal lives. / Mass Media and Communication

Yes / Although there are several marketing implications that have been considered in the context of social media marketing, less attention has been paid to the influence of antecedents of consumer brand engagement (telepresence, social presence and involvement) and their consequences for non-profit organizations. Thus, the main purpose of current research is to examine the influence of telepresence, social presence and involvement on consumer brand engagement (CBE) (second-order), which in turn affects electronic word of mouth and willingness to donate. To test the proposed model, this paper used social media platforms. We employed a Facebook page that presents non-profit organizations (brands) using a sample of non-students. We found that telepresence, social presence and involvement positively impact CBE, which in turn impacts electronic word of mouth and willingness to donate. The findings of our research demonstrate how CBE is formed in this particular context and what outcomes are to be expected, with important implications for both marketing theory and practice.

This Bachelor’s Thesis in Computer Science investigates the use of the parameterised facial animation model named CANDIDE-3 (J. Ahlberg, 2001) in Telepresence communication with relatively cheap hardware. An experimental study was conducted to evaluate how well an implementation using the Microsoft Kinect Face Tracking device could capture and animate the 6 classical emotional states: joy, sadness, surprise, anger, fear and disgust. A total of 80 test candidates took part in a survey where they were to try and classify the emotional states of images of photographed and animated faces. The animated faces were created using the prototype system built for the purpose of the survey and rendered onto the robotic Furhat face (Al Moubayed, S., Skantze, G., Beskow, J., Stefanov, K., & Gustafson, J, 2012). Results showed that a person’s emotional state is preserved very well through the animation technique used, and for some basic emotions, like joy or sadness, the animation could even amplify the emotional state for the viewer. However, the 6 Action Units captured from the Kinect device were not enough to sufficiently distinguish between even some of most the basic emotional states (e.g. disgust, anger). / Denna kandidatuppsats inom Datateknik undersöker hur väl den parametriserade animationsmodellen CANDIDE-3 (J.Ahlberg, 2001) kan användas för att visa ansiktsuttryck inom Telepresence-sammanhang med hjälp av relativt billig hårdvara. En experimentell studie utfördes för att undersöka hur väl en implementation som använder Microsoft Kinects ansiktsigenkänning kunde fånga och animera de 6 klassiska ansiktsuttrycken: glädje, sorg, förvåning, ilska, rädsla och avsky. Totalt deltog 80 personer i undersökningen där deras uppgift var att klassificera känslomässiga tillstånd från fotograferade och animerade ansikten. De animerade ansiktena skapades med hjälp av det prototypsystem som byggdes i undersökningens syfte och renderades på det robotiserade Furhat-ansiktet (Al Moubayed, S., Skantze, G., Beskow, J., Stefanov, K., & Gustafson, J, 2012). Resultat visade att en persons känslomässiga tillstånd väldigt väl bevaras genom animationstekniken som används, och för några grundläggande känslor, såsom glädje och sorg, kunde animationen till och med förstärka det känslomässiga tillståndet för åskådaren. De 6 AU-enheterna som fångas av Kinect-enheten var dock inte tillräckliga för att särskilja till och med några av de mest grundläggande känslomässiga tillstånden (såsom avsky, ilska).

This Master Thesis concerns a telepresence implementation which utilizes state-of-the-art virtual reality combined with live 360 degree video. Navigation interfaces for telepresence with virtual reality headsets were developed and evaluated through a user study. An evaluation of telepresence as a communication media was performed, comparing it to video communication. The result showed that telepresence was a better communication media than video communication.

Inledning: Även om distansterapi visat sig vara effektivt och ger ökad tillgänglighet är många terapeuter ändå tveksamma till formatet. Syfte: Genom att undersöka hur övergången till distansformat enligt psykodynamiskt orienterade terapeuter påverkar den terapeutiska processen, dess ram och relationella kvalité ges ett bidrag till förståelse av denna tvekan. Metod: En kvalitativt inriktad fenomenologisk studie av semistrukturerade intervjuer med fem terapeuter. Resultat: Tematisk analys visar två teman: Närvaro och En ny situation med två respektive fyra underteman: möjliggörande och saknad respektive kropparnas kommunikation, saknad avgränsning, ramarbete och inre upptagenhet. Diskussion: En inre upptagenhet kan göra att närvaro som relationell kvalité i bemärkelsen emotionell, kognitiv och funktionell tillgänglighet försvåras i distansformatet. Inre upptagenhet kan bero på de ramfrågor som aktualiseras i övergången. Undersökningen resulterar i en modell som visar att i den mån en viss terapeutisk teknik, känsla i rummet eller terapeutroll föreligger som målsättning i den terapeutiska processen kommer den inre upptagenheten sannolikt kvarstå. Ökad förståelse för terapeuters målsättningar i och med den terapeutiska processen föreslås som en nyckel för vidare acceptans av distansformatet. / Introduction: Even though distance therapy has been shown to be effective across a range of measures and increases access many psychotherapists still remain sceptic to the format.   Aim: By examining how psychodynamic psychotherapists experience transitioning to distance therapy as regards the therapeutic process this study results in a contribution to the understanding of the continuing scepticism among therapists.  Method: A qualitative, phenomenological study of semi-structured interviews with five psychotherapists using thematic analysis.  Result: Two themes are identified: Presence and A new situation with two and four subthemes respectively: enabling and lamented; bodily communication, demarcation, therapeutic frame and preoccupation. Discussion: Due to preoccupation presence understood as a relational quality of emotional, cognitive and functional availability could be continually lamented in distance therapy. The discussion results in a model showing that if a certain therapeutic technique, feeling in the room or therapeutic role is an underlying intention in the therapeutic process preoccupation will continue to be a factor in distance therapy encounters. Increased knowledge as regards therapists´ intentions in the therapeutic process is forwarded as a key factor to further acceptance of the distance therapy format.
