AirSniffer: A Smartphone-Based Sensor Module for Personal Micro-Climate MonitoringSmith, Jeffrey Paul 05 1900 (has links)
Environmental factors can have a significant impact on an individual's health and well-being, and a primary characteristic of environments is air quality. Air sensing equipment is available to the public, but it is often expensive,stationary, or unusable for persons without technical expertise. The goal of this project is to develop an inexpensive and portable sensor module for public use. The system is capable of measuring temperature in Celsius and Fahrenheit, heat index, relative humidity, and carbon dioxide concentration. The sensor module, referred to as the "sniffer," consists of a printed circuit board that interconnects a carbon dioxide sensor, a temperature/humidity sensor, an Arduino microcontroller, and a Bluetooth module. The sniffer is small enough to be worn as a pendant or a belt attachment, and it is rugged enough to consistently collect and transmit data to a user's smartphone throughout their workday. The accompanying smartphone app uses Bluetooth and GPS hardware to collect data and affix samples with a time stamp and GPS coordinates. The accumulated sensor data is saved to a file on the user's phone, which is then examined on a standard computer.

The important technification of the developed societies has also impacted the contemporary museography. The arrival of the smartphones introduced cultural consumption patterns that felt utterly new. These affected, inevitably, the conception of the digital assets specifically developed for the exhibition spaces. The use of technology in cultural environments has become a general trend and myriad institutions have resorted to them to complement their funds and contents.
This investigation will thoroughly elaborate on the factors that determine the quality of those smartphone applications published by museums. For that aim, an analysis of the evolution of the media in recent years will be presented in order to have an ample idea of the current situation of this field of study. Subsequently, a change in the conceptualization of the approach and in the design of these questions will be proposed, and the visitor will become the process vertebral axis. Hence, both the design discipline from the user experience and its implementation in the museum field will be meticulously analyzed., and their validity will be verified through their exhibition environment.
Lastly, a specific methodology based on these design principles will be implemented, where the development of smartphone applications and the exhibition practice will be linked. The purpose of this methodology will be to organize the necessary phases of a project with these features, determine the main aspects that will guarantee the quality of the final outcome and, ultimately, be useful in the implementation of meaningful digital experiences for museums. / La importante tecnificación de las sociedades desarrolladas ha tenido su reflejo dentro de la museografía contemporánea.

Kvalitetssäkra hälsoapplikationer : Vilka upplevda förväntningar och krav finns? / Quality-assurance of health apps : What are the perceived expectations and requirements?Provender Jonasson, Felicia January 2021 (has links)
Bakgrund: Antalet hälsoapplikationer växer för varje dag och det finns ett behov av att säkerställa kvaliteten på dessa, för att skapa riktlinjer för utvecklare, stödja användarna och tydliggöra vad vårdgivare kan rekommendera till sina patienter. Syfte: Syftet med detta arbete var att undersöka synen på kvalitetsmärkningar och krav som kan ställas på hälsoapplikationer ur kvalitets- och säkerhetsaspekt, med perspektiv utifrån myndigheter och appleverantörer, vårdsektor och app-användare. Material och metod: Studien har använt sig av en kvalitativ forskningsmetod med semistrukturerade intervjuer, där totalt sjutton intervjuer genomförts med representanter från tre olika myndigheter, SIS, app-leverantörer, vårdpersonal och app-användare. Alla intervjuer transkriberades ordagrant, bearbetades med hjälp av kodning, kategorisering och analys för att se mönster, likheter och variationer. Slutligen delades detta in i teman som presenterar dessa mönster i resultatet. Resultat: Alla parter är positivt inställda till en kvalitetsmärkning på hälsoapplikationer, även om kännedomen kring det pågående standard-arbetet varierade hos de tillfrågade. Det finns en förväntan både hos användare och inom vården om en ökad användning av hälsoapplikationer i framtiden och möjligheten att dela hälsodata. Vårdpersonalen är restriktiva till vad de vågar rekommendera för hälsoappar idag, men hoppas och tror att en märkning kan förändra det. De anser att säkerhet, integritet och kvalitet är viktigt, men likväl design, användarupplevelse och spelifiering. Myndigheterna och leverantörerna upplever en låg kontroll kring att ställa krav själva eller ha mandat till förändring inom området. Slutsats: Samtliga yrkesroller är enade om att det är en politisk fråga och att juridiska trösklar behöver ses över när det gäller krav, främja nya digitala lösningar och innovation inom friskvård och sjukvård. En ny standard upplevs vara i rätt riktning och inkludera det mesta som önskats, men frågan består i var ansvaret kommer ligga över att den följs, hur respektive parter ska förhålla sig till den, andra krav och kvarhållande ”föråldrade” lagstiftningar. En genomgående röd tråd är uppmaningen om tydlighet och önskan om ökad politisk drivkraft inom området.

Technology adoption at the workplace : Optimal office utilization in the context of sustainabilityHimmel, Nik January 2020 (has links)
Nowadays, sustainability in general and energy-efficiency in specific have become very populardue to environmental issues which can be directly traced back to a wasteful lifestyle of currentgenerations. Therefore, the European Commission specified European Union-wide targets andpolicy objectives in order to achieve a cut in greenhouse gas emissions from 1990 levels by atleast 40% and at least 32,5% improvement in energy-efficiency until 2030 with an option toupward the values by 2023.The literature review of this study showed that former research mainly chose an overallperspective about systems which support people and organizations in living more sustainablywithout covering a specific topic and without elaborating on a concept for a specific use-case.Most of the studies examined technology in regard to a piece of hardware which is integratedinto an existing environment (e.g. household), where no continuous interaction of its users isnecessary. Furthermore, none of it addressed how an organization, along (and in tightcooperation) with its members, can become more sustainably by implementing a technology—where technology refers to an app (software)—which enables employees to live moresustainably at the workplace.In order to tangle the identified gap, the author of this study created a concept of an app whichcan optimize a utilization of office spaces. The aim of this app is to group colleagues togetherin offices according to their project, team or previous seating habits in order to avoidunnecessary heating, air-conditioning and lighting of unused rooms (e.g. pool offices,conference rooms). As an organization should not just create a guideline to which everyemployee must stick to, this study elaborates on possible prompts and constraints (e.g.employees which have concerns about privacy). To achieve that, a web-based survey wasconducted in Germany in order to evaluate the hypotheses emerged from the literature review.From this aim, the research question ‘Which elements prompt and constrain employees to adoptan app that addresses optimal office utilization?’ emerged.Notwithstanding the thoroughly conducted literature review and the emerged hypotheses, noneof the stated hypotheses could have been confirmed and verified.

Regularized Greedy Gradient Q-Learning with Mobile Health ApplicationsLu, Xiaoqi January 2021 (has links)
Recent advance in health and technology has made mobile apps a viable approach to delivering behavioral interventions in areas including physical activity encouragement, smoking cessation, substance abuse prevention, and mental health management. Due to the chronic nature of most of the disorders and heterogeneity among mobile users, delivery of the interventions needs to be sequential and tailored to individual needs. We operationalize the sequential decision making via a policy that takes a mobile user's past usage pattern and health status as input and outputs an app/intervention recommendation with the goal of optimizing the cumulative rewards of interest in an indefinite horizon setting. There is a plethora of reinforcement learning methods on the development of optimal policies in this case. However, the vast majority of the literature focuses on studying the convergence of the algorithms with infinite amount of data in computer science domain. Their performances in health applications with limited amount of data and high noise are yet to be explored. Technically the nature of sequential decision making results in an objective function that is non-smooth (not even a Lipschitz) and non-convex in the model parameters. This poses theoretical challenges to the characterization of the asymptotic properties of the optimizer of the objective function, as well as computational challenges for optimization. This problem is especially exacerbated with the presence of high dimensional data in mobile health applications.
In this dissertation we propose a regularized greedy gradient Q-learning (RGGQ) method to tackle this estimation problem. The optimal policy is estimated via an algorithm which synthesizes the PGM and the GGQ algorithms in the presence of an L₁ regularization, and its asymptotic properties are established. The theoretical framework initiated in this work can be applied to tackle other non-smooth high dimensional problems in reinforcement learning.

"Using the bad for something good" : Exploring the possible paradox of meditation apps in light of digital stressRose, Johanna January 2020 (has links)
This study investigates meditation apps from a user perspective. While focusing on the user, interviews with psychologists and an auto-ethnographic study of three different meditation apps were used to inform the research, enrich the findings and create an as wholesome as possible picture. The research aims to explore user’s motivations and experiences as well as the possible paradox of meditation through a smartphone in light of digital stress. Taking a user-centered approach, the theories informing this work include the Instrumental Theory of Technology; Theories of the self, including Foucault’s Practices of Selfhood and Lipton’s self-tracking practices; Existential Media Theory; and theories of the public and the private including the Publicization of the Private. This study shows that high achieving young adults use meditation apps as a convenient, accessible and cost-effective tool for self-improvement. However, users mainly see the apps as a stepping block and have the goal to eventually establish a meditation practice without using the phone. While users think that it would be better to meditate without an app, their meditation app allows them to fit the meditation practice into the context of their busy everyday life.

A process for managing benefits of mobile enterprise applications in the insurance industryKnoesen, Henri 16 May 2019 (has links)
Mobile enterprise applications (MEAs) are found in increasing numbers in organisations as smart-devices become an everyday necessity amongst employees and customers. Large amounts are invested in these applications, so it is important to see the value in improved business processes and the consequential improvement in business performance. Realising the benefits from their use is important to obtain the value from these investments. Yet, benefits management (BM) is poorly implemented in companies and a first step to improve this situation is to improve the visibility of the benefits that can be achieved by using MEAs. Hence the primary question asked in this study is “How can MEA benefits be successfully realised?” The strategy used to answer the question was action research in a single organisation using three MEAs in two different action research cycles. The study was conducted in a short-term insurance company in the Western Cape of South Africa with an established IT and project capability. Globally, the short-term insurance industry is under a significant threat from disruption by market entrants who don’t have to navigate legacy systems and who are more agile with their product offerings. Traditional insurers are looking for innovative solutions to transform the way in which insurance is sold and serviced. A BM process, which was modified from the literature, was refined through action cycles in three MEA projects to improve benefits realisation. The result showed that for MEA projects, which are not very large investments relative to other IT projects, a lighter, less cumbersome process was more practical and acceptable in the organisation. The creation of a benefits and risks template, during the action cycles, helped the organisation to build stronger business cases for MEA projects and also allowed for more comprehensive benefit identification, measurement and tracking, ultimately realising business performance improvements. The study also used a survey amongst 88 brokers and assessors to determine the factors which influence their adoption of these MEAs. The most significant factors influencing user adoption were the company’s willingness to fund the smart-devices, the ease of use of the MEA, job relevance and location dependence. A limitation of this study is that the organisation has a particular approach to project funding whereby the importance of BM is weighed against the cost of the project, hence BM is more important for very expensive projects. While the model prescribed in this study was sufficient in this context, it may not be suitable for organisations that are more conscientious about BM. This model would need to be tested in other contexts for transferability. A further limitation was the duration of time available for conducting this study because this was a PhD research project. Further action cycles might have refined the process further. The findings from this study are relevant to researchers and to organisations wanting to deploy MEAs. The BM process defined in this study can be used in MEA projects as a process to manage the identified benefits and ensure that they are realised. The benefits template can be used as a first step in the BM process to build the business case and the risks template can be used to identify potential problems that could hinder benefits realisation and can used to put mitigating actions in place to prevent problems to benefits realisation. The identification of factors influencing adoption of MEA can help organisations focus on these factors to ensure that their MEAs are used and they thereby derive benefits. The theoretical contributions of this study are a process model for the BM body of knowledge and a model explaining the factors influencing symbolic adoption of MEA. The identification and description of benefits and risks extends the body of knowledge for mobile applications research. These specific issues in the context of MEAs in the short-term insurance industry are understudied.

Can we play our way to a more circular fashion world? : A quantitative study about the impact of gamification on consumer attitudes and intentions to use C2C appsArnesson, Amanda, Westman, Sofia January 2022 (has links)
As new styles rapidly replace the old and garments are discarded, fast fashion and clothing consumption contribute to a serious and negative environmental impact. Previous research and fast fashion’s negative sustainability consequences all imply that a change is required. Peoples’ desire “to fit in” and the resulting clothing consumption has to find its solution, and second hand consumption is suggested as a viable answer. But, to buy pre-loved garments has been considered inconvenient, time-demanding and unappealing. These attitudes towards a more sustainable consumption behavior therefore becomes a barrier to a circular fashion economy. Consequently, companies are trying to develop and offer new services that could improve the situation. One of these marketplaces are Consumer to Consumer (C2C) apps, which connect sellers and buyers of second hand items through their user accounts, meaning that the company behind the service is not involved in the transaction other than as the supplier of the software. Previous research suggests that people's intentions towards pursuing a desired consumer behavior is positively encouraged by gamification elements. Despite this, C2C apps on the Swedish market do not use these features to promote second hand consumption. Within gamification, there are a myriad of elements and tools to choose from, where three of the most commonly used gamification elements to improve attitudes are points, badges and leaderboards, also known as the PBL triad. The Theory of Planned Behavior (TPB) states that attitude towards the behavior, together with subjective norm and perceived behavior control are the components that affect an intention to engage in a behavior, which predicts whether individuals will actually perform the behavior. Based on these considerations, this thesis identified a research gap in how gamification can affect Swedish consumers’ attitude towards using C2C apps gamified with points, badges and leaderboards. We examine how this attitude, subjective norms and perceived behavioral control, influence their intentions to use these apps. This formulates the studies research questions “ How are Swedish consumers’ attitudes towards using a C2C app affected by the gamification elements points, badges and leaderboards? and How are Swedish consumers’ intentions to use a gamified app to make wardrobe updates affected by their attitudes towards it, subjective norms and perceived behavioral control?” To examine this issue we developed a survey to collect information about Swedish consumers’ attitudes and potential behavioral intentions to use a gamified C2C app. The data analysis proves that all three elements in the PBL triad are able to positively affect consumer attitudes. Also, the behavioral predictions stated by the TPB were supported by all three components; consumers' expectations regarding subjective norms and behavioral control, with attitude towards the behavior being the strongest predictor.
