En precisionsstudie av förstärkt verklighet som positioneringsverktyg

Didriksson, Mattias, Blomkvist, Anders January 2015 (has links)
This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality. The study successfully shows that this can be implemented without compromising user experience as well as achieving a precision below 13 millimeters. The AR-tool has been proven to reduce time consumption of the task by up to four times compared to the manual method using a folding ruler.

Gestural communication in Parkinson's disease : language, action and cognition

Humphries, Stacey Alexandra January 2016 (has links)
Parkinson’s disease (PD) is a neurodegenerative condition which results in severe motor impairment. Deterioration in multiple domains of cognition is another hallmark of PD. Together, these motor and cognitive impairments impact substantially on language and communication. Co-speech gestures are a form of action and are also part of linguistic processes, yet have rarely been explored in PD. Gestures can provide imagistic depictions of concepts described by speech and contribute to communication in healthy individuals. They rely on visual, spatial, and motor simulations and imagery, which may be impaired in PD. It is therefore of clinical importance to evaluate how co-speech gestures might be impaired to understand the extent of communicative impairment in PD. PD can also provide a useful model to understanding the cognitive basis of co-speech gesture in healthy people. In Chapter 2, participants described isolated actions. Gesture rate did not differ between the two groups, however, the groups differed in terms of the visual perspective they adopted when depicting actions in gesture. Controls preferred a “character viewpoint” or first-person perspective where their hands represented the hands of the actor, whereas PD patients preferred an “observer viewpoint” or third-person perspective, where their hand represented a whole person. This finding was replicated and extended in Chapter 3 where low-motion and high-motion actions were described in a longer narrative task. PD patients produced fewer character viewpoint gestures when describing high-motion action events, suggesting a difficulty in simulating these events from a first-person perspective. In addition, PD patients had difficult depicting “manner” (how an action is performed) features in gesture during high but not low motion. Extending the findings of Chapter 2, whilst overall rate of gesture production was not affected, PD patients produced action gestures at a significantly lower rate than controls. Chapter 4 took a different focus by investigating gesture depictions of static spatial (rather than dynamic action) features via a house description task. Gesture rate did not differ, but the groups depicted different types of spatial properties to a different extent. Whilst both groups predominantly gestured about location and relative position information, PD patients gestured more about directions whereas controls gestures more about shape and size information. This suggests that different strategies were being employed by the two groups. Finally, testing young adults’ comprehension of these spatial gestures in Chapter 5 revealed that gestures did not significantly improve comprehension of either PD patients’ or controls’ spoken messages, though there may have been ceiling effects. However, both PD patients and controls were viewed as more competent when their messages were viewed with gestures. The findings suggest a selective action-gesture deficit in PD which complements work demonstrating action-verb impairments in these patients, and supports gesture production theories which hypothesise a role for motor simulations and imagery. Overall gesture rate appears to be largely unaffected. The effects of PD can be felt beyond changes to goal-directed action, in the realms of language and social behaviour, but gestures may be able to improve listeners’ social perceptions of PD patients.

Dialogues with the unwell body : Rethinking the notion of wellbeing in HCI from feminist and somaesthetic perspectives

Kaklopoulou, Eirini January 2022 (has links)
With the emergence of ubiquitous computing and biosensing technologies, there is a growing interest to explore wellbeing within design research. This paper unpacks the notion of wellbeing from somaesthetic and feminist perspectives. Through a series of evocative first-person design explorations, a soma-based design workshop, and a cultural probes study, I re-think wellbeing along the concept of the ever-changing body, a continuously and holistically changing organism with human and non-human features which is influenced by society, culture and economy. This contributes to a new understanding on how we relate to wellbeing and to practices of care and wellness, and how might we design technologies for awareness and understanding of our wellbeing. As the process unfolds, I discuss alternative design approaches for digital wellbeing considering aspects of touch and discomfort, materiality as a probe and care for the more-than-human. I argue that the slowness and openness of somaesthetic design paired with the open-ended character of cultural probes reveal tensions that exist between individuals and wellbeing and facilitate a greater diversity of bodies and minds. With this project, I propose an open-ended design approach to wellbeing building on the soma design space that can be used in the design of biosensing technologies for wellbeing. / Med framväxten av allestädes närvarande datorer och bioavkänningssensing-teknologier finns det ett växande intresse för att utforska välbefinnande inom designforskning. Denna artikel tar upp begreppet välbefinnande på en individuell berikad med andras förstapersonsupplevelser ur somestetiska samtoch feministiska perspektiv. Genom en serie stämningsfulla designutforskningar i första person, en soma-baserad designworkshop och en kulturell probesstudie utforskarstuderar jag välbefinnande längs konceptet ever-changing body, en kontinuerligt och holistiskt föränderlig organism med mänskliga och icke-mänskliga egenskaper som påverkas av samhälle, kultur och ekonomi. Detta bidrar till en ny förståelse för hur vi förhåller oss till välbefinnande och till praxis för vård och välbefinnande, samtoch hur vi kan utforma teknologier för medvetenhet och förståelse för vårt välbefinnande. Jag hävdar att långsamheten och öppenheten ihos somestetisk design i kombination med den öppna karaktären hos kulturella undersökningar avslöjar spänningar som finns mellan individer och välbefinnande vilkeoch underlättar en större mångfald av kroppar och sinnen. Allt eftersom processen utvecklas, jag diskuterar alternativa designmetoder för digitalt välbefinnande med tanke på aspekter såsomav beröring och obehag, materialitet som en sond och mer än mänsklig design i åtanke. Med det här projektet föreslår jag en öppen designstrategi för välbefinnande som bygger på soma-designutrymmet som kan användas vid utformningen av bioavkännings-teknologier för välbefinnande.

Perceptual elements affecting navigation of players in first person games

Viio, Leon January 2019 (has links)
Context. This thesis’ goal was to test whether or not perceptual elements which do not intrude on player movement were reliable methods of leading the player through an environment without specifically telling them where to go, focusing on players already accustomed to first person perspective(FPP) games. This was a remake of an older experiment in the hopes of finding different results than last time it was tested, by making improvements to the test chambers, and altering the application of these different elements which were used to test the participants navigation. Objectives. In the user study, the player was forced to pick between two mirrored pathways with a specific variable distinguishing them in the hopes that the players will follow a predictable pattern. By proving that none heads up display(HUD) elements were reliable tools for player navigation, it could introduce new ideas for level designers and artists working within the industry to guide player pathing in a first person perspective game. Methods. This experiment was constructed using different soft-wares commonly used in the game industry, and was made to be easily repeatable by other who would like to expand on the subject. References used were mostly scientific articles which could be found using google scholar, ACM library and researchgate. The articles in question were sourced by their use as references and the validity was assessed by their abstract, discussion thought process and own references used. Results. Using 17 different students from Blekinge institute of technology as participants in three different test scenarios where they had to navigate their surroundings by choosing between one of two pathways. The results show promising indications for further research in the subject, with the large majority of people picking the predicted path. Conclusions.While the data collected by the participants show promising results in favor of reliable means of navigation through the environmental effects used in the experiment, there were many altering factors at play which potentially could have altered the results. The topic of player navigation in games are a widely contested area with many factors at play. More research is necessary to reach a more conclusive answer, but shows great potential judging by the results.

Being a Translator : - With a Licence to Improve

Ivarsson, Siw January 2013 (has links)
This paper sets out to investigate and discuss what a translator may do when the source text for some reasons needs to be improved. The analysis is based on examples from a source text in need of quite extensive editing. This editing is called for to be able to present a translation that is satisfactory as well for the target reader as for the translator. To achieve this, the translator has to deal with a series of crucial decisions. One important determinant of any decision on part of the translator is, of course, the quality of the source text, which may vary a great deal. Originals sometimes exhibit flaws of various kinds. In such cases, what is the translator supposed to do? Is (s)he supposed to deliver a translation that contains the same mistakes as the ST, or is (s)he supposed to rewrite a poor text? The main focus of the present study is to discuss possible strategies for changes and to find support for the translator to work with improving editing in a text that needs to be improved. More specifically, focus is on looking at the strategies that are available when it comes to three specific problem areas, viz person perspective, author visibility and repetition. The study initiates a further discussion of the translator's mission – should it include making a brilliant version of a poor source text? It was found that the translator should not transfer language flaws that might appear in a source text with no stylistic pretentions, but instead produce an improved target text, even if that entails rather extensive editing.

Architecture as Narrative in First Person Level Design : A Reading of Mirror’s Edge Catalyst

Hemberg, Max, Josefsson, Ludwig January 2021 (has links)
The video games industry is rapidly developing as technology allows designers to create increasingly comprehensive worlds for their players to explore. Acknowledging the experience gained by architects designing similar structures for the physical world, this thesis explorescross-disciplinary research. The relationship between architecture and level design is here utilized to further the understanding of architectural space within first-person video games. A textual analysis is performed on Mirror’s Edge Catalyst to investigate ways in which architecture may contribute to the narrative of a game. This reading embodies the aspirations of precedent studies, used by architects to understand and analyse the components within an architectural composition. The thesis is guided by the question “How can architectural space support the narrative in levels of first-person video games?” and manages to uncover multiple layers to the design of Mirror’s Edge Catalyst. The research conveys that the expectedgameplay experience guides the composition of the architecture within the level. Here the horizontal and vertical planes that define space may be utilized to facilitate the narrative throughtheir shape and configuration. The spatial segments are then arranged into linear or centralizedorganizations emphasizing the narrative of the level. Finally, throughout these spatial organizations monumental architecture is applied which provides stages that assist in conveyingthe focal point of the narrative. / Den digitala spelindustrin utvecklas snabbt i samband med teknologiska framsteg. Detta resulterar i förutsättningar för speldesigners att utveckla utförliga virtuella världar för deras spelare att utforska. Genom att erkänna den välutvecklade erfarenheten erhållen av arkitekter i deras arbete att konstruera världens samhällen, antar sig detta kandidatarbete tvärvetenskaplig forskning. Relationen mellan arkitektur och level design används här för att främja förståelsen för arkitektoniskt utrymme inom videospel som utspelar sig i första person. En textanalys är utförd på Mirror’s Edge Catalyst med syftet att undersöka olika möjligheter för arkitektur att bidra till narrativ inom spel. Denna analys aspirerar till att förhålla sig till målet av en prejudikatstudie som tillåter arkitekter att förstå och analysera komponenter inom en arkitektonisk komposition. Kandidatarbetet vägleds av forskningsfrågan ”Hur kan arkitektoniskt utrymme användas för att stödja ett narrativ i banor från första-persons videospel?”. Forskningen visar att den förväntade spelupplevelsen inom en bana styr den arkitektoniska kompositionen. Horisontella och vertikala ytor används för att definiera utrymme medan deras form och sammansättning ger plats åt banans narrativ. Det uppdelade utrymmet placeras sedan in i linjära eller centraliserade organisationer vilket styrker den narrativa upplevelsen som etableras. Under dessa organisationer placeras storslagen arkitektur, vilket ger upphov till scener vars syfte är att underlätta kommunikationen av fokuset inom narrativet.

Experiences, networks and uncertainty : parenting a child who uses a cochlear implant

Adams Lyngbäck, Liz January 2016 (has links)
The aim of this dissertation project is to describe the ways people experience parenting a deaf child who uses a cochlear implant. Within a framework of social science studies of disability this is done by combining approaches using ethnographic and netnographic methods of participant observation with an interview study. Interpretations are based on the first-person perspective of 19 parents against the background of their related networks of social encounters of everyday life. The netnographic study is presented in composite conversations building on exchanges in 10 social media groups, which investigates the parents’ meaning-making in interaction with other parents with similar living conditions. Ideas about language, technology, deafness, disability, and activism are explored. Lived parenting refers to the analysis of accounts of orientation and what 'gets done' in respect to these ideas in situations where people utilize the senses differently. In the results, dilemmas surrounding language, communication and cochlear implantation are identified and explored. The dilemmas extend from if and when to implant, to decisions about communication modes, intervention approaches, and schools. An important finding concerns the parents’ orientations within the dilemmas, where most parents come up against antagonistic conflicts. There are also examples found of a development process in parenting based on lived, in-depth experiences of disability and uncertainty which enables parents to transcend the conflictive atmosphere. This process is analyzed in terms of a social literacy of dis/ability.

Hand-held Augmented Reality for Facility Maintenance

Liu, Fei January 2016 (has links)
Buildings and public infrastructures are crucial to our societies in that they provide habitations, workplaces, commodities and services indispensible to our daily life. As vital parts of facility management, operations and maintenance (O&amp;M) ensure a facility to continuously function as intended, which take up the longest time in a facility’s life cycle and demand great expense. Therefore, computers and information technology have been actively adopted to automate traditional maintenance methods and processes, making O&amp;M faster and more reliable. Augmented reality (AR) offers a new approach towards human-computer interaction through directly displaying information related to real objects that people are currently perceiving. People’s sensory perceptions are enhanced (augmented) with information of interest naturally without deliberately turning to computers. Hence, AR has been proved to be able to further improve O&amp;M task performance. The research motif of this thesis is user evaluations of AR applications in the context of facility maintenance. The studies look into invisible target designation tasks assisted by developed AR tools in both indoor and outdoor scenarios. The focus is to examine user task performance, which is influenced by both AR system performance and human perceptive, cognitive and motoric factors. Target designation tasks for facility maintenance entail a visualization-interaction dilemma. Two AR systems built upon consumer-level hand-held devices using an off-the-shelf AR software development toolkit are evaluated indoors with two disparate solutions to the dilemma – remote laser pointing and the third person perspective (TPP). In the study with remote laser pointing, the parallax effect associated with AR “X-ray vision” visualization is also an emphasis. A third hand-held AR system developed in this thesis overlays infrared information on façade video, which is evaluated outdoors. Since in an outdoor environment marker-based tracking is less desirable, an infrared/visible image registration method is developed and adopted by the system to align infrared information correctly with the façade in the video. This system relies on the TPP to overcome the aforementioned dilemma.
