Measuring Customer Experience in Mobile Internet

Problems in the mobile services are complex where the lack of the user analysis is not the modest issue. User centered design has increasingly become as a basis for the design of mobile services. The concept of user centered design gives end-user extensive attention at each stage of the design process. Mobile service providers want to offer experiences for users and clearly the users look for services that can provide pleasant experiences. In this thesis, the elements of user experience in mobile internet were studied as well as user experience measuring methods were researched. This study was looking for user experience measuring metrics and methods to specify new factors to measure user experience. During this thesis research project an application called CEM4Mobile was designed and implemented. CEM4Mobile is an application for observing and analysing user experience based on the user activity and behaviour. As a result of this thesis, a collection of user experience elements and measuring metrics were found. The elements and metrics were designed and implemented to CEM4Mobile product, which measures user experience. It was found out that the user experience measuring methods were based on interaction between two people but CEM4Mobile makes user observation programmatic.

Prevalence of Problematic Mobile Phone Use in British Adolescents

The problematic use of mobile phones among adolescents has not been widely studied. There are very few instruments for assessing potential technological addiction to mobile phones, or for categorizing different types of users or uses. The most widely used scale is the Mobile Phone Problem Use Scale (MPPUS), which is used to study adult populations, and has been applied in various forms in international contexts. The aims of this study were to adapt the Spanish version of this scale (MPPUSA) to British adolescents, and then to estimate the prevalence of possible problematic users. A questionnaire was administered to a sample of 1,529 secondary school pupils aged between 11 and 18 years, with 1,026 completed questionnaires being collected. The analysis showed that the factor and construct validity and reliability were comparable to those obtained in previous studies. The prevalence of problematic users among the students was 10%, and the typical problematic user tended to be an adolescent between 11 and 14 years old, studying in a public school, who considered themselves to be an expert user of this technology, who made extensive use of his/her mobile phone, and who attributed the same problem of use among their peers. These users presented notable scores in all the symptoms covered by the scale used to assess problematic use. In conclusion, the adaptation of the MPPUSA as a screening scale for British adolescents presents good sensitivity and specificity for detecting the main addictive symptoms proposed in this validated version.

Adaptación española del "Mobile Phone Problematic Use Scale" para población adolescente

El uso problemático del teléfono móvil es un fenómeno emergente en nuestra sociedad, que parece afectar especialmente a la población adolescente. El conocimiento acerca del uso problemático de esta tecnología resulta necesario, dado que puede desarrollarse un patrón comportamental con características adictivas. Apenas existen escalas que midan el posible uso problemático del móvil y ninguna adaptada exclusivamente a población adolescente española. La escala más utilizada internacionalmente es la Mobile Phone Problematic Use Scale (MPPUS). El objetivo de este estudio es adaptar el MPPUS a la población adolescente española. Se administró la versión española del cuestionario a una muestra de 1132 de 12 a 18 años. La fiabilidad y la validez factorial eran comparables a las obtenidas en población adulta, por lo que la medida del uso problemático del móvil en los adolescentes españoles es unidimensional. Se detectó una prevalencia del 14.8% de usuarios problemáticos.

Com va passar amb Internet, es tracta d’un procés d'innovació pel qual els formats de contingut, les pràctiques de consum i els models de negoci característics de la televisió i la xarxa, per exemple, s'adapten, primer, al nou mitjà, per a després desenvolupar formes i models específics que aprofiten les potencialitats de personalització, geolocalització i conectivitat ubiqua.

'No country for old men?' Analyzing older people s attitudes toward mobile communication

Mobile technology plays an increasing role in interpersonal communication,representing a useful resource for different age cohorts. While the usage ofmobile communication by younger people has received a wide attention fromcommunication scholars, its usage by older people is less explored. Thegoal of our research project is to analyse the usage of mobile phones by theelderly in Italy. We conducted 51 semi-structured interviews in Rome and in amid-range town located in Umbria, between October 2013 and February 2014.Our study explores older users¿ motivations and usage practices, their perceptions of mobile phones, theiradoption and domestication of mobile phones, their usage skills. More specifically,our analysis focuses on: - personal characteristics - personal networks (personalnetwork composition, self-perceived social life, communication channels) -adoption of mobile telephone - consumption patterns of mobile devices - usedmobile services - location and mobility of mobile telephone - current mobilecharacteristics - attitude and opinions towards mobile technology Our preliminaryresults show major differences in users¿ behaviours and perceptions, that canbe related to age cohorts (younger olds vs older olds); socio-cultural levels;vital trajectories (in terms of professional and familiar status); and gender.

Mobile system for pump working point estimation

In the current economy situation companies try to reduce their expenses. One of the solutions is to improve the energy efficiency of the processes. It is known that the energy consumption of pumping applications range from 20 up to 50% of the energy usage in the certain industrial plants operations. Some studies have shown that 30% to 50% of energy consumed by pump systems could be saved by changing the pump or the flow control method. The aim of this thesis is to create a mobile measurement system that can calculate a working point position of a pump drive. This information can be used to determine the efficiency of the pump drive operation and to develop a solution to bring pump’s efficiency to a maximum possible value. This can allow a great reduction in the pump drive’s life cycle cost. In the first part of the thesis, a brief introduction in the details of pump drive operation is given. Methods that can be used in the project are presented. Later, the review of available platforms for the project implementation is given. In the second part of the thesis, components of the project are presented. Detailed description for each created component is given. Finally, results of laboratory tests are presented. Acquired results are compared and analyzed. In addition, the operation of created system is analyzed and suggestions for the future development are given.

Service Description Creation Empowerment to Mobile End Users

Increasing usage of Web Services has been result of efforts to automate Web Services discovery and interoperability. The Semantic Web Service descriptions create basis for automatic Web Service information management tasks such as discovery and interoperability. The discussion of opportunities enabled by service descriptions have arisen in recent years. The end user has been considered only as a consumer of services and information sharing occurred from one service provider to public in service distribution. The social networking has changed the nature of services. The end user cannot be seen anymore only as service consumer, because by enabling semantically rich environment and right tools, the end user will be in the future the producer of services. This study investigates the ways to provide for end users the empowerment to create service descriptions on mobile device. Special focus is given to the changed role of the end user in service creation. In addition, the Web Services technologies are presented as well as different Semantic Web Service description approaches are compared. The main focus in the study is to investigate tools and techniques to enable service description creation and semantic information management on mobile device.

Certificate Handling Middleware for Mobile Devices

The purpose of this thesis was to study how certificates could be used to improve security of mobile devices. In the theoretical part the usage of certificates to improve security is explained. In the practical part a concept of certificate handling middleware is introduced and implemented. This is to demonstrate what kind of functionality is needed to provide an improvement over the current situation in security with mobile devices. The certificate handling middleware is a concept that would work better if implemented directly into mobile device's core functionality. Many of the mobile devices have a certificate store to some degree and often it is not used to store other people's certificates. A certificate store combined with address book and added with possibility to add attributes to the people such as group memberships would be sufficient to satisfy the needs of many emerging sharing and social applications.

Mobile Teleoperation of a Mobile Robot

This thesis describes the design and implementation of a graphical application on a mobile device to teleoperate a mobile robot. The department of information technology in Lappeenranta University conducts research in robotics, and the main motivation was to extend the available teleoperation applications for mobile devices. The challenge was to port existing robot software library onto an embedded device platform, then develop a suitable user interface application that provides sufficient functionality to perform teleoperation tasks over a wireless communication network. This thesis involved investigating previous teleoperation applications and conducted similar experiments to test and evaluate the designed application for functional activity and measure performance on a mobile device which have been identified and achieved. The implemented solution offered good results for navigation purposes particularly for teleoperating a visible robot and suggests solutions for exploration when no environment map for the operator is present.

Designing and Implementing Mouse Emulation to Touchscreen Operated Mobile Web Browsers

Browsing the web has become one of the most important features in high end mobile phones and in the future more and more people will be using mobile phone for web browsing. Large touchscreens improve browsing experience but many web sites are designed to be used with a mouse. A touchscreen differs substantially from a mouse as a pointing device and therefore mouse emulation logic is required in the browsers to make more web sites usable. This Master's thesis lists the most significant cases where the differences of a mouse and a touchscreen affect web browsing. Five touchscreen mobile phones and their web browsers were evaluated to find out if and how these cases are handled in them. Also as a part of this thesis, a simple QtWebKit based mobile web browser with advanced mouse emulation model was implemented, aiming to solve all the problematic cases. The conclusion of this work is that it is feasible to emulate a mouse with a touchscreen and thus deliver good user experience in mobile web browsing. However, current highend touchscreen mobile phones have relatively underdeveloped mouse emulations in their web browsers and there is a lot to improve.

Real-time Musical Pair Improvisation on Mobile Devices

This thesis discusses the design and implementation of a real-time musical pair improvisation scenario for mobile devices. In the scenario transferring musical information over a network connection was required. The suitability of available wireless communication technologies was evaluated and communication was analyzed and designed on multiple layers of TCP/IP protocol stack. Also an application layer protocol was designed and implemented for the scenario. The implementation was integrated into a mobile musical software for children using available software components and libraries although the used platform lead to hardware and software constraints. Software limitations were taken into account in design. The results show that real-time musical improvisation can be implemented with wireless communication and mobile technology. The results also show that link layer had the most significant effect on real-time communication in the scenario.
