Användandet av mobila enheter med appsystem och appars fackmannamässiga potential inom byggbranshen

Åström, Joakim January 2014 (has links)
Mobile devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews. Answers given by the interviews were then used as a basis to survey the usage of mobile devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication. A further more advanced study of a floor plan making app, called MagicPlan has also been done. The equipment that were used were Samsung Galaxy S2, Apple iPad , Samsung Note 10.1 Tablet, Leica Disto, Leica Scanstation C10, Canon Pixma MP270. The results of the examination show that the usages of mobile devices are widely spread in the building industry, however, seldom to its full potential. The results also indicates that the tested apps likely can be used by professionals in some cases.

"Mobilen - En extra kompis" : En kvalitativ studie av mobilanvändning bland högstadieelever

Henriksson, Sarah, Rydhög, Klara January 2014 (has links)
Denna uppsats syfte har varit att undersöka vilken roll mobilen spelar i en grupp ungdomars liv och då framförallt i skolan. Vi har intervjuat åtta elever på en högstadieskola samt utfört observationer för att få en så klar bild som möjligt av deras förhållande till mobilanvändning. Tidigare forskning har visat att mobilens roll har kommit att bli större och viktigare och den sociala interaktionen som tidigare i större utsträckning skett ansikte mot ansikte är nu mer benägen att ske genom mobilen. Mobilens inverkan på individ och samhället har både positiva och negativa effekter, vilket undersöks i uppsatsen. De frågeställningar som behandlas rör hur eleverna upplever dagens mobilanvändning, hur de använder sina mobiler och hur detta påverkar den sociala interaktionen. Även huruvida eleverna har ett behov av att vara anträffbara samt hur de känner av mobilens påverkan? Uppsatsens sociologiska analys görs med hjälp av teman som behandlar konsumtion, modernitet, tid och rum, social interaktion genom mobilen och nätverkssamhället. Resultatet visar att mobilen spelar en stor roll i ungdomarnas liv och att den sociala interaktionen till viss del begränsas av mobilen. Eleverna upplever att de ständigt måste kunna vara anträffbara och uppdaterade och kan känna sig illa till mods när mobilen inte finns tillgänglig. / This paper has aimed to explore the role that mobile phone plays in a group of young people's lives in school. We interviewed eight students at a secondary school and performed observations to get as clear a picture as possible of their mobile phone use. Previous research has shown that mobile's role has become more and more important and the social interaction that were previously more widely been face to face is now more likely to be through mobile phone. The mobile's impact on the individual and society has both positive and negative effects. The issues addressed concerns how students experience today's smartphone use, how they use their phones and how this affects social interaction. Even whether students have a need to be reachable and how they feel of the phone's impact? The sociological analysis of this paper is done using themes that deal with consumption, modernity, time and space, social interaction through the smartphone and the network society. The result shows that mobile phone plays a big role in young people's lives and social interactions to some extent limited by the mobile phone. Students feel that they must constantly be reachable and updated and may feel uneasy when the phone is not available.

The Use of Smartphone Applications for Learning Purposes among Saudi Students

Alomran, Amal I 08 1900 (has links)
The purpose of the current study was to confirm or dismiss Saudi students' behavioral intention with regard to using smartphone applications for learning purposes. A quantitative, non-experimental survey research design and descriptive research conducted on the determinants -performance expectancy, effort expectancy, and social influence- that predict Saudi students' intention at University of North Texas to use smartphone applications for learning purposes, based on the unified theory of acceptance and use of technology (UTAUT) as the framework. This study aims at filling gap found in understanding of students' intentions and their behaviors regarding the adoption and use of the Smartphone applications. Data was collected by means of an online questionnaire. The hypothesized model validated empirically using data collected from around 234 Saudi students who enrolled at University of North Texas. The model developed from UTAUT explained 50.1% of the variance of behavioral intention, and behavioral intentions explained 13.6% of the variance of usage behavior. The result of this study support that the determinants of performance expectancy, effort expectancy, and facilitating conditions were the highest predictors of behavioral intentions in using smartphone applications for learning purposes. The results of this study could encourage students, educators, and the Saudi Arabia Ministry of Education to provide educational applications that meet students' needs for information and knowledge.

Conception et validation d’un système ubiquitaire centré autour du Smartphone et dédié à l’amélioration de l’autonomie de la personne / Design and scientific validation of a smartphone based ubiquitous system dedicated to improvement of the autonomy of the person

Mourcou, Quentin 25 January 2016 (has links)
La perte d'autonomie pour une personne accroît son isolement, son anxiété et peut mener jusqu’à la dépression. Ce travail doctoral a été initié et motivé par la volonté de maintenir, voir d'améliorer, l'autonomie des personnes. La diminution de la mobilité est directement liée à la diminution de l'autonomie. En intervenant sur la mobilité, avec l'aide des nouvelles technologies, nous sommes capables de proposer des solutions innovantes à ce problème. Nous avons constaté que le Smartphone est un outil disposant d'un ensemble de capteurs et actuateurs nous permettant d'intervenir sur l'évaluation et la rééducation de capacités liées à la mobilité.L'objectif principal de ce travail doctoral est ainsi de concevoir et d'évaluer un système ubiquitaire, basé sur Smartphone et dédié à l'amélioration de l'autonomie de la personne via la rééducation, en dehors du cadre soignant, et l’aide aux déplacements. Afin d'atteindre cet objectif général, nous avons d'abord cherché à savoir si le Smartphone et ses capteurs embarqués apportaient la fiabilité nécessaire à la conception d'un tel système. Puis, nous avons dû répondre à des objectifs secondaires qui sont de pouvoir, à partir d'un Smartphone, réaliser l'évaluation, la surveillance et l'amélioration 1) des capacités proprioceptives de la personne et 2) des déplacements et mouvements de la personne à mobilité réduite, toutes deux essentielles au maintien de l'autonomie.Dans leur ensemble, les résultats présentés dans ce travail doctoral démontrent que :• Le Smartphone est fiable dans le cadre de la mesure clinique angulaire• Le Smartphone est un outil capable de mesurer, suivre, contrôler et corriger un mouvement ou une posture.• Le Smartphone est capable de collecter des données cinématiques pour relever l'accessibilité de la voirieCes résultats ouvrent la perspective de l'utilisation d'un outil ubiquitaire, le Smartphone, dans le cadre de la mesure, le suivi, le contrôle et la correction d'un mouvement, d'une posture ou encore d'un déplacement, et cela de manière autonome. Ainsi, afin de passer le stade de preuve de concept, des études cliniques peuvent dès à présent être menées afin de déterminer l'impact de notre système sur la santé et le bien-être de la personne. / Loss of mobility and independence for a person increase his isolation, anxiety and can lead to depression. This doctoral work was introduced and motivated by the goal to maintain, even to improve, the autonomy of the people. The decrease of the mobility is directly connected to the decrease of the autonomy. By occurring on mobility, with the help of new technologies, we are capable of proposing innovative solutions to this problem. We noticed that the Smartphone is a tool composed of a set of sensors allowing us to intervene on the evaluation and the rehabilitation of capacities connected to the mobility.The main objective of this doctoral work is to conceive and to estimate an ubiquitous system, based on Smartphone and dedicated to the improvement of the autonomy of the person by rehabilitation at home and the mobility aid. To reach this general goal, we tried at first to know if the Smartphone and its embedded sensors brought the reliability necessary for the conception of such a system. So, to improve the autonomy, we had to answer secondary objectives which are, from a Smartphone, to be able to realize assessment, monitoring and improvement of the 1) proprioceptive capacities of the person and of 2) travels and movements of the person with reduced mobility, which are both of them essential in the preservation of the autonomy.As a whole, the results presented in this doctoral work demonstrate that:• The Smartphone is reliable within the domain of the clinical measurement• The Smartphone is a tool for assessment, monitoring, improving and training a movement or a posture.• The Smartphone is capable of collecting kinematic data to raise the accessibility of the public road network.These results opens the prospect of the use of an ubiquitous tool, the Smartphone, within the framework of the assessment, monitoring, improving and training of a movement, a posture or a displacement, in an autonomous way. To cross the stage of proof of concept, clinical trials can be right now led to determine the impact of our system on the health and the well-being of the person.

Como produto resultante, apresentou-se o aplicativo AppAquisBluet e suas funcionalidades básicas, com a função de realizar aquisições de dados em tempo real, haja vista que esses dados podem ser apresentados em arquivo de texto ou graficamente e armazenados em banco de dados para futuras análises. Para tal aquisição, utilizou-se o hardware condicionador de sinal via bluetooth desenvolvido para converter o sinal analógico, captado pelo circuito da ponte de Weatstone, para digital e transmitido ao aplicativo AppAquisBluet, usando a comunicação bluetooth, plotando os dados no visor do aplicativo, além de exportar para a memória de armazenamento do smartphone como arquivo de texto para serem tratados, utilizando o software Excel. / The handheld mobile devices are gaining market and consolidating its position as one of the tools most commonly used in daily life of corporations or common users. It is due to investments of the mobile companies, networking companies, software and hardware companies and so on. This work addressed the evolution of mobile technology. We observed how mobile phones have turned into smartphones able to manage almost everything by our hands. Of course, because of sophisticated operational systems and specific platforms for development of applications. The aim of this study was directed to the development of AppAquisBluet application. It used the Android development platform that holds 75% of the mobile market by Google and its allies. Further, it is a modern platform, flexible, open source, an excellent cost and benefit compared to other platforms. That is why it is perfect for the implementation of the AppAquisBluet application. Accordingly, the methods and techniques used in its construction were the same of the Android platform, including the SDK (Software Development Kit), the Java programming language, the Bluetooth API, third-party libraries like GraphView, used in the graphic implementation of the project, and the efficient SQLite database designed for mobile applications. The resulting product was the AppAquisBluet application and its basic features, including the function of performing data acquisition in real time. The data can be coded in a text file or graphically and stored in a database for future analysis. For this acquisition, we used the signal conditioner hardware via Bluetooth. It was developed to convert to digital signal the analog signal received by Weatstone Bridge and then the digital signal could be transmitted to the AppAquisBluet application, using Bluetooth communication by plotting the data in the application display, and exporting to the smartphone storage memory as a text file that can be treated using the Excel software.

On mobile augmented reality applications based on geolocation / Vers des applications de réalité augmentée utilisant la géolocalisation

Michel, Thibaud 10 November 2017 (has links)
Les applications de réalité augmentée peuvent être conçues de différentes manières, mais encore très peu tirent partie de la géolocalisation.Pourtant, aujourd'hui, avec la multitude de capteurs embarqués dans nos smartphones et nos tablettes, l’utilisation de la géolocalisation dans le contexte de la RA (RA Geo) semble très prometteuse.Dans ce travail de thèse, nous avons contribué sur plusieurs aspects fondamentaux de la RA Geo: l'estimation de la position du dispositif, l'estimation de son orientation, ainsi que sur l'impact de ces estimations sur le rendu des informations virtuelles.Dans un premier temps, nous avons étudié l'estimation de l’orientation du téléphone.Nous avons réalisé le premier benchmark dans un motion lab afin de comparer et d'évaluer les différents filtres de la littérature sur une base commune.Celui-ci a permis de produire la première analyse comparative approfondie des différentes approches.Nous avons aussi proposé un nouveau filtre dont le but est de minimiser l’effet des perturbations magnétiques omniprésentes en intérieur et avons quantifié son apport par rapport aux techniques existantes.Dans un deuxième temps, nous avons étudié l'estimation de la position du téléphone lorsqu’il est porté par un piéton.Il existe de nombreux travaux sur les technologies de localisation mais il est difficile de trouver un benchmark qui évalue les différentes technologies dans le cas d’un smartphone grand public. Ainsi, à nouveau nous avons produit le premier benchmark pour analyser de façon comparative les différentes techniques de localisation qui peuvent être utilisées avec un smartphone.Dans un troisième temps, nous avons proposé une méthode pour caractériser l'impact des estimations d'orientation et de positionnement sur le rendu des informations virtuelles.Ceci a permis d'identifier des critères permettant de comprendre plus précisément les limites de faisabilité de différent cas d'utilisation de la RA Geo.Enfin, nous avons proposé un nouveau framework pour faciliter la conception d’applications de la RA Geo.Nous montrons comment les données de cartographie peuvent être utilisées et enrichies à l’aide d’une nouvelle sémantique utilisant OpenStreetMap.Nous avons créé un visualiseur permettant d'afficher des éléments virtuels sur le flux de la caméra.Ce framework intègre différents modules pour la localisation, l’orientation, la gestion des points d'intérêts, le geofencing, l’audio spatialisé, et le rendu 2D ou RA.Finalement, trois exemples d'applications d'AR Géo ont été réalisés à partir de ce framework.TyrAr est une application pour visualiser des informations sur les sommets et les villes environnantes.AmiAr permet de contrôler de certains objets de domotique dans un appartement connecté.Venturi Y3 est une visite guidée de la ville de Grenoble avec des expériences de RA avec de l'audio. / Applications for augmented reality can be designed in various ways, but few take advantage of geolocation.However, nowadays, with the many cheap sensors embedded in smartphones and tablets, using geolocation for augmented reality (Geo AR) seems to be very promising.In this work, we have contributed on several aspects of Geo AR: estimation of device positioning and attitude, and the impact of these estimations on the rendering of virtual information.In a first step, we focused on smartphone attitude estimation.We proposed the first benchmark using a motion lab with a high precision for the purpose of comparing and evaluating filters from the literature on a common basis.This allowed us to provide the first in-depth comparative analysis in this context.In particular, we focused on typical motions of smartphones when carried by pedestrians.Furthermore, we proposed a new technique for limiting the impact of magnetic perturbations with any attitude estimation algorithm used in this context.We showed how our technique compares and improves over previous works.In a second step, we studied the estimation of the smartphone's position when the device is held by a pedestrian.Altough many earlier works focused on evaluation of localisation systems, it remains very difficult to find a benchmark to compare technologies in the setting of a commodity smartphone. Once again, we proposed a novel benchmark to analyse localisation technologies including WiFi fingerprinting, WiFi trilateration, SHS (Step and Heading System) and map-matching.In a third step, we proposed a method for characterizing the impact of attitude and position estimations on the rendering of virtual features.This made it possible to identify criteria to better understand the limits of Geo AR for different use cases.We finally proposed a framework to facilitate the design of Geo AR applications.We show how geodata can be used for AR applications.We proposed a new semantics that extends the data structures of OpenStreetMap.We built a viewer to display virtual elements over the camera livestream.The framework integrates modules for geolocation, attitude estimation, POIs management, geofencing, spatialized audio, 2.5D rendering and AR.Three Geo AR applications have been implemented using this framework.TyrAr is an application to display information on mountain summits and cities around the user.AmiAr allows one to monitor lights, shutters, tv in a smart appartment.Venturi Y3 is an AR-Tour of Grenoble with audio description and experiences.

Cognitive load in smartphone calendar applications / Kognitiv belastning i smartphone kalenderapplikationer

Hellqvist, Adrian, Olsson, Tommy January 2018 (has links)
The use of smartphone applications has increased dramatically in the last decade. With the technology being ubiquitous around us it is important to reduce the required cognitive demand for interacting with the technology. A common use of smartphones is calendar applications. This paper investigates if cognitive load can be lowered by using a calendar application specifically designed with cognitive load in mind compared to the widely used Google Calendar. The hypothesis is that the application will generate a lower cognitive load in comparison. An experiment was conducted where participants were instructed to perform a primary task by following given instructions of what to do in the calendar application while also performing a secondary task. There were no significant differences in performance except for two tasks where the new app performed worse. Participants also reported a higher level of frustration for the new app which could mean that their cognitive load was slightly higher. / Användandet av smartphone applikationer har ökat dramatiskt under det senaste decenniet, eftersom att tekniken hela tiden är närvarande runt om oss så är det viktigt att minska de kognitiva kraven som behövs vid användandet. Ett vanligt användande av smartphones är kalenderapplikationer, den här studien undersöker om den kognitiva belastningen kan minskas vid användandet av en kalender app genom att använda applikation som designats med kognitiv belastning i åtanke för att sen jämföras mot Google Kalender. Hypotesen är att applikationen kommer att generera en lägre kognitiv belastning i jämförelse. Ett experiment utfördes där deltagarna instruerades att utföra en huvuduppgift som innebar att utföra givna instruktioner med uppdrag i kalendarapplikationen, samtidigt som en sekundär uppgift utfördes där deltagarna fick trycka på en knapp när en signal hördes. Det var ingen signifikant skillnad i prestation förutom i två uppgifter där appen presterade sämre, deltagarna rapporterade också en högre nivå av frustration vilket skulle kunna innebära att den kognitiva belastningen var något högre.
