31	Application development for smartwatches : An investigation in suitable smartwatch applications / Applikationsutveckling för smarta klockor : En undersökning inom lämpliga applikationer för smarta klockor Isacson, Dan January 2015 (has links) The smartwatch has been predicted to be the next big thing in the ecosystem of wearable and mobile devices. The success of the smartphone has a lot to do with the support from third party developers and their applications. This support will most likely be of utmost importance if the smartwatch is going to be successful. But what are suitable applications for this type of device? What are people's expectations and opinions on smartwatches? This thesis work delved into these matters with focus on development for the Apple Watch. This was done through an online survey that reached more than 1400 people, through a field study for one person that used the smartwatch as an air-travel tool and finally through a usability test conducted on five people that tried out several applications, most of which were developed for this project. Four different applications were implemented: a timetable application, a museum audio-guide, a game and an airline application. The results indicate that people generally expected the smartwatch to act as an extension for their smartphones and notifications seemed to be an area in which the smartwatch excelled. The results also show that there are many applicable areas the smartwatch can be used for, but that interaction with these should be kept quick and simple. This is extra important given the limited screen-size and special considerations should be taken on what content to display. / Smarta klockor har länge framstått som nästa stora insteg inom ekosystemet av mobila enheter. Succén bakom smarttelefoner har mycket att göra med det stora stödet från tredjepartsutvecklare och deras applikationer. För att smarta klockor ska nå liknande nivåer är det troligt att detta tredjepartsstöd är av stor betydelse. Men vad är lämpliga applikationer för detta format? Vad har folk för förväntningar på denna plattform? Det här arbetet har handlat om dessa ämnen med fokus på utveckling mot Apple Watch. Arbetet har gjorts genom en enkätundersökning online som nått över 1400 användare, genom en fältstudie på en person där en applikation för flygresor testats samt genom ett användartest på fem personer där dessa fått testa på ett antal applikationer för Apple Watch, varav de flesta av dessa var utvecklade för detta projekt. Totalt implementerades fyra applikationer: en tidtabellsapplikation för kommunaltrafik, en ljudguide för ett museum, ett spel och en applikation för flygresande. Resultaten visar att folk verkar förvänta sig att en smart klocka ska fungera som en förlängning av deras smarttelefon och det verkar som att notifikationer är ett väldigt bra användningsområde för formatet. Resultaten visar också att det verkar finnas många olika användningsområden för smarta klockor men att interaktioner med dessa bör vara korta och lätthanterliga. Detta är extra viktigt givet den begränsade skärmstorleken och man bör noga överväga hur och vad man presenterar för användaren. smart watch watches application apple watch apple smartwatch smartwatches development smart klocka applikation utveckling apple watch apple smartklocka smartklockor klockor Computer Sciences Datavetenskap (datalogi)

Sjöstedt, Gustav, Mannerford, Sara January 2023 (has links) Background: This study discusses the phenomenon of luxury goods as investment assets,focusing on luxury watches in particular. The rise of globalization and increased wealth,particularly among the middle and high-income groups in developing countries, hascreated a larger potential customer base for luxury items. This has led to an increasing interest in luxury goods as investment assets, including collectibles such as cars, art, andwine. The recent development of online niche marketplaces for luxury goods has enabledthe systematic collection of data, facilitating research on Veblen goods as alternativeinvestment assets. Therefore, it is interesting to analyze the financial performance ofinvestments in luxury watches as compared to traditional assets. Purpose: The purpose of this study is to analyze the comparative performance ofinvesting in luxury watches versus traditional assets such as equities and bonds. Methodology: This study collects data on luxury watch prices and characteristics. Thehedonic pricing method is used to regress the price of the watches on their characteristics.The regression results are used to analyze the price impact of the characteristics, as well asto create a watch price index. In order to evaluate the index performance, data is collectedfor the MSCI World Index and the Bloomberg U.S. Aggregate Bond Index. For all the indices, the financial metrics of the Sharpe ratio, Treynor ratio, CAPM, and Jensen’s alphaare calculated. Conclusion: This study suggests that luxury watches, with their wide price ranges and high resale value, have been a viable option for portfolio diversification during thestudied five-year period between 2018 and 2023. The watch index yields an averagereturn of 2.01 % and a cumulative return of 49.35 %, outperforming the MSCI World Indexwith average returns of 1.38 % and the Bloomberg U.S. Aggregate Bond Index with -0.01%, and cumulative returns of 31.90 % and -0.15 %, respectively. The watch index alsooutperforms the compared indices in terms of the financial metrics Sharpe ratio, Treynorratio, CAPM, and Jensen’s alpha. The results suggest that the most important valuedrivers for luxury watches are: Brand (Audemars Piguet, Patek Philippe, and VacheronConstantin), Features (Chronograph, tourbillon, and rotating bezel) and Case Material(bronze, rose gold, and yellow gold).

33	Zpracování dat ze senzorů wearable zařízení pomocí strojového učení / Processing Sensor Data from a Wearable Device by Machine Learning Hlavačka, Martin January 2019 (has links) The goal of this master's thesis is to analyze the situation of wearable devices with the Android Wear operating system and recognition capabilities of various movement activities using neural networks. The primary focus is therefore on identifying and describing the most appropriate tool for recognizing dynamic movements using machine learning methods based on data obtained from this type of devices. The practical part of the thesis then comments on the implementation of a stand-alone Android Wear application capable of recording and formatting data from sensors, training the neural network in a designed external desktop tool, and then reusing trained neural network for motion recognition directly on the device.
34	Wearables and the potential of Google Glass Aleksandrian, Arsen, Sigrén Vinblad, Emil January 2015 (has links) The Mobile Life (TML) is a company with great passion for mobile devices that has set its primary focus on developing tailor-made mobile applications. Some of their bigger clients consist of airlines where TML designs, develops and delivers applications, in which travelers who travel with the airline can use to browse through, reserve and book flights. Wearable Technology is being more and more embraced as the future big addition to the ecosystem of mobile devices and exploring what some of the more prominent wearables have to offer is very much in the interest of aspiring companies like TML. To understand more in-depth what it means to develop applications for devices that might suffer from vast limitations in regards to interaction and feedback, we would first investigate what coming wearables could be recognized as prominent. The wearables that we concluded as suitable to investigate closer were Google Glass, Android Wear and various smartwatches. Out of these, Google Glass was the device chosen to act as our platform when exploring the potential of a wearable. A suitable way of understanding the possibilities and limitations of user interaction for Google Glass was to develop our own flight booking application for Glass. The realization we got was that there are various aspects of Glass that limits the kind of applications that can be made for it. The two primary things are the limits of the hardware and the fact that user interaction has taken a step back. From the graphical directmanipulation interaction that we nowadays are so used to in smartphones, to a simple menu system with limitations to how much the user can interact and how much feedback the program can show the user. / The Mobile Life (TML) är ett företag med stort engagemang inom mobil utveckling med fokus på att leverera skräddarsydda mobila lösningar. Vissa av deras större kunder inkluderar flygbolag som TML designar, utvecklar och levererar applikationer för resenärer att söka boka och köpa flygbiljetter. Wearable Technology blir mer och mer accepterat som nästa stora tillskott till det mobila ekosystemet och däri ligger intresset av att undersöka vad de mest hypade enheterna har att erbjuda för avancerande företag som TML. För att få en bättre insikt i vad det betyder att utveckla applikationer för enheter som markant skiljer sig från mobiltelefoner och surfplattor i avseende av prestanda och möjligheter gällande inmatning och utmatning av information tog vi fram de mest framträdande enheterna. De mest framträdande enheterna visade sig vara Google Glass, Android Wear och diverse smarta klockor. Utifrån dessa valdes Google Glass som vår plattform för att undersöka möjligheterna för wearables. Ett lämpligt sätt att förstå möjligheter och begränsningar inom användarinteraktion för Google Glass var att utveckla vår egen flygboknings applikation för Glass. Insikten vi fick var att det finns olika aspekter av Glass som begränsar den typ av applikation som kan göras för den. De två primära sakerna är begränsningar för hårdvara och det faktum att användarinteraktion har på ett vis tagit ett steg tillbaka. Från den grafiska direktmanipulering interaktion som vi idag är så vana vid i smartphones, till ett enkelt menysystem med begränsningar för hur mycket användaren kan interagera och hur mycket feedback programmet kan visa användaren.

36	NONINVASIVE MEASUREMENT OF HEARTRATE, RESPIRATORY RATE, AND BLOOD OXYGENATION THROUGH WEARABLE DEVICES Jason David Ummel (10724028) 29 April 2021 (has links) <p>The last two decades have shown a boom in the field of wearable sensing technology. Particularly in the consumer industry, growing trends towards personalized health have pushed new devices to report many vital signs, with a demand for high accuracy and reliability. The most common technique used to gather these vitals is photoplethysmography or PPG. PPG devices are ideal for wearable applications as they are simple, power-efficient, and can be implemented on almost any area of the body. Traditionally PPGs were utilized for capturing just heart rate, however, recent advancements in hardware and digital processing have led to other metrics including respiratory rate (RR) and peripheral oxygen saturation (SpO2), to be reported as well. Our research investigates the potential for wearable devices to be used for outpatient apnea monitoring, and particularly the ability to detect opioid misuse resulting in respiratory depression. Ultimately, the long-term goal of this work is to develop a wearable device that can be used in the rehabilitation process to ensure both accountability and safety of the wearer. This document details contributions towards this goal through the design, development, and evaluation of a device called “Kick Ring”. Primarily, we investigate the ability of Kick Ring to record heartrate (HR), RR, and SpO2. Moreover, we show that the device can calculate RR in real time and can provide an immediate indication of abnormal events such as respiratory depression. Finally, we explore a novel method for reporting apnea events through the use of several PPG characteristics. Kick Ring reliably gathers respiratory metrics and offers a combination of features that does not exist in the current wearables space. These advancements will help to move the field forward, and eventually aid in early detection of life-threatening events.</p> Biomedical Instrumentation Medical Devices Rehabilitation Engineering Flexible Manufacturing Systems Engineering Instrumentation Photoplethysmographic Signals photoplethysmography photoplethysmography sensor design photoplethysmography signal recording wearable sensors Fitness tracker Smart ring Smart Watches electrocardiograms blood oxygenation respiratory rate respiratory sinus arrhythmia Real-Time Respiration Rate opioid use disorder opioid use disorder treatment settings apnea hypoxia syndrome apnea detection sensor
37	Les écoles d' horlogerie de Besançon : une contribution décisive au développement industriel local et régional (1793-1974) / The Besancon watchmaking schools Briselance, Claude 28 October 2015 (has links) L’Histoire des écoles d’horlogerie de Besançon est inhérente à la naissance et à la continuité d’une industrie spécifique très localisée sur un territoire. Avec elles nous partons de l’ère « proto-industrielle » qui plonge ses racines dans les idéaux révolutionnaires de 1793 pour aboutir aux bouleversements technologiques de l’électronique et du « quartz » des années 1970… S’inscrivant sur la longue durée, trois « écoles » vont se succéder. Pour répondre aux attentes d’une industrie horlogère qui doit constamment faire face aux évolutions techniques, chacune à sa manière, va innover pour constituer un « corpus » original de formation qui n’est pas sans bousculer les rites et usages du temps. Si les deux premières « écoles » eurent une durée de vie limitée, la dernière entité, née en 1861 de la volonté municipale, va pendant plus d’un siècle, accompagner toute une ville (et sa région) dans sa réussite industrielle. Dès sa création, et au fur et à mesure des adaptations qu’elle a su mettre en place, par la qualité et la spécificité des formations dispensées, elle va irriguer de ses élèves toute une industrie toujours à l’affût de personnels qualifiés. Au plan national elle va diffuser le nom de Besançon comme « capitale française de l’horlogerie » en formant nombre d’horlogers-rhabilleurs tenant boutiques et autres ateliers de réparation par tout le territoire… Elle va servir de référence pour implanter dans la Cité des laboratoires de recherche et d’enseignement supérieur : un Observatoire chronométrique, une École d’ingénieurs, un Centre d’études horlogères et de développement industriel (Cétéhor)… Elle va contribuer à la diversification industrielle de la ville dans des domaines connexes à l’horlogerie, notamment dans le découpage, la micromécanique, l’appareillage et les microtechniques… Nationalisée en 1891, elle fait dès lors partie de la petite élite des Écoles Nationales Professionnelles (par assimilation), qui vont marquer le développement industriel du Pays. En 1933, quand elle intègre ses nouveaux locaux, par le nombre et l’originalité de ses filières (de l’ouvrier qualifié à l’ingénieur), par sa dotation en matériels modernes, elle est signalée comme étant le « premier établissement de l’enseignement technique » en France. Le cheminement de cette dernière école fait aussi ressortir une histoire « humaine », « prosopographique », qui met en exergue les nombreux anciens élèves qui se sont lancés avec grande réussite dans la création d’entreprises. Restés fidèles à leur école, ils ont contribué au renom et au développement de la richesse économique de la cité et de sa région… Avec ces écoles d’horlogerie, on aborde enfin l’histoire de l’Enseignement Technique en France. Pour répondre à la demande d’une industrie horlogère en pleine croissance qui déplorait les carences de l’apprentissage en atelier, elles ont été pionnières en ouvrant la voie de « la scolarisation » de la formation professionnelle. Par leurs innovations pédagogiques, et soutenues par les Anciens Élèves, elles ont su établir un lien « École-Entreprise » des plus fructueux qui marque encore la mémoire collective des Bisontins…En 1974 elle perd toute référence à l’horlogerie pour devenir le Lycée Jules Haag. Le temps de l’histoire est désormais advenu pour tenter de comprendre ce qui a fait la force et la réussite de ces « Écoles d’horlogerie » dans leur participation active, sur la durée, à la prospérité économique et industrielle d’une ville et de sa région… / The history of the watchmaking schools in Besançon is part of the birth and continuous development of a specific industry in a very limited sector of the French territory. When studying those schools we start at the « protoindustrial » time with its roots in the revolutionary ideals of 1793 and end up with the technological upheavals of electronics and the « quartz » technology in the 1970s. Three « schools » followed one another over the long term. Each school aimed at satisfying the demands of a watchmakng industry confronted to rapidly changing technical evolutions ; so it innovated in its own way by creating an original « corpus » in the students training and most of the time upset the practices and common ideas of the time. If the first two « schools » had a limited lifespan, the last one created in 1861 by the town council itself has been supporting the industrial growth of the city and the surrounding region. Since its foundation it has stuck to the industrial reality by placing the emphasis on high standards and opening new specific branches whenever necessary, thus answering the needs of firms always looking for highly qualified staff. For a large number of French people Besançon became the « capital town of the watchmaking industry » thanks to the shops or repair workshops kept by Besançon-trained former students all over France… It served as a background to set up research and university laboratories in the city : Observatoire Chronométrique, Ecole d’Ingénieurs, Centre d’Etudes Horlogères et de Développement Industriel (Cétéhor)… It contributed to the industrial diversification of the town in fields related to watchmaking such as mechanical cutting, micromechanics, equipment and microtechniques. It was nationalized in 1891 and then belonged to the very small elite goup of the Professional National Schools that influenced the future industrial development of the country. In 1933 it moved into sparkling-new premises and was acknowledged as the flagship of technical education in France : it offered a large number of innovating courses ranging from the skilled worker to the engineer and was granted the latest equipments in every field. The path of this new school also enhanced a « humane » and « prosopographical » history ; it highlighted the part played by the numerous former students who created their own successful businesses. Being faithful to their old school they contributed to the renown and economic growth and prosperity of the city and its region… Beyond the local impact we must regard the history of the watchmaking schools as an important part of the history of Technical Education in France. To meet the needs of a soaring watchmaking industry they opened the way to the transfer of professional training from apprenticeship in workshops with its observed shortcomings to education in technical high schools. Their pedagogical innovations, the strong support of their former students created a vital school-business link that still lives on in the collective memory of the town inhabitants.In 1974 its name changed to Lycée Jules Haag thus losing any reference to watchmaking. Let us now try and understand the strong influence and success of those watchmaking schools, the active part they played in the economic industrial prosperity of a town and its surrounding region… Acteurs Anciens élèves Appareillage Apprentissage Atelier-École Besançon Bijoutiers Cétéhor Chronométrie Collège Technique Contrôle et régulation Découpage mécanique Développement industriel Diplômes Directeurs Doubs École Municipale d’horlogerie École Nationale d’horlogerie École Nationale professionnelle Élèves Enseignement Technique Formation professionnelle Franche-Comté Horlogers Ingénieurs Internat Institut de Chronométrie Lycée Technique Manufacture horlogère Mécaniciens de précision Montres Micromécanique Microtechniques Nationalisation Observatoire chronométrique Occupation Œuvre de Saint-Joseph Petite mécanique de précision Praticiens Professeurs Techniques Programmes Révolution Scolarisation des apprentissages Service du Travail Obligatoire Techniciens Actors Apprenticeship Besançon Cetehor Chronometricobservatory Chronometry Compulsory labor organisation Control and regulation Diplomas Doubs Engineers Equipment Former students Franche-Comté Industrial developmet Institut of chronometry Jewellers Mechanical cutting Micromechanics Microtechnical Municipal watchmaking school Nationalization National watchmatching school Occupatiion Precission mechanics Professional national school Professional training Program Residential scholl Revolution St-Joseph institute School directors Schooling of the learning Secondary technical college Small precision mechanics Students Swiss immigration Technical education Technical high school Technical professors Technicians Watches Watchmakers Watch manufacture Workshop-School
