Purpose: The purpose of this paper is to shed light on which role authenticity plays in mobile dating apps, an environment where users can present themselves only with a limited amount of information. By investigating how users create their profiles and evaluate others, the existing knowledge on authenticity and self-presentation can be advanced. Methodology: The research applied a relativist and
This paper describes an explorative user study of how two different user groups experience current, as well as envisioned new mobile navigation systems. Two groups have been the primary target in this study; a group of elderly people and a group of relatively young university students that were visually impaired. The study consisted of three parts: a focus group/test, a diary study and a design wo
A mobile stroke unit (MSU) is an ambulance, where stroke patients can be diagnosed and treated. Recently, placement of MSUs has been studied focusing on either maximum population coverage or equal service for all patients, termed efficiency and equity, respectively. In this study, we propose an unconstrained optimization model for the placement of MSUs, designed to introduce a tradeoff between eff
The tremendous amount of multimedia applications running across the wireless communication medium makes quality of service (QoS) a fundamental requirement for mobile ad hoc networks. However, it is not easy to incorporate QoS into these networks. Moreover, the growing number of group-oriented applications also necessitates the efficient utilisation of network resources. The multicast model is a pr
Sony Mobile has a quite large internal user group with the purpose of investigating the usability of their mobile devices. The Telephony Domain was using among other techniques usability testing to evaluate the usability of their products. The performed conventional usability testing has its limitations e.g. the controlled test environment cannot fully represent real life setting and it’s very exp
Abstract The competition regarding market shares in the mobile handset industry is tough. Today the mobile phone is more and more becoming a personal accessory and trends in shape, color and material are changing rapidly. The keypad is one of a phone’s many components which the end user gets in touch with first. It is used to activate the phone, and it is what the user feels and looks at initially
Detta examensarbete undersöker hur ett visuellt designverktyg för byggande av användargränssnitt till iOS, Android, och webben kan konstrueras. Även fast det finns en hel del verktyg för att designa och bygga mobil- och webbappar, så finns det i nuläget inga visuella designverktyg för att bygga en gemensam app för alla tre plattformar. Utöver detta, så undersöker arbetet potentiella lösningar till This thesis investigates how a visual design tool for building cross-platform application interfaces for iOS, Android, and web can be constructed. While there are plenty of tools for building and designing mobile and web apps, there are currently no visual design tools for building cross-platform apps for all three platforms. Beyond this, the thesis explores potential solutions for problems relat
In this article we give an overview of some challenges in how to make geospatial information more useable and accessible. We also suggest a roadmap for dealing with these challenges – and introduce a new EU project HaptiMap.
A mobile stroke unit (MSU) is an advanced ambulance equipped with specialized technology and trained healthcare personnel to provide on-site diagnosis and treatment for stroke patients. Providing efficient access to healthcare (in a viable way) requires optimizing the placement of MSUs. In this study, we propose a time-efficient method based on a genetic algorithm (GA) to find the most suitable am
Measuring MIMO-SAR is an important part of mobile handset evaluation, following the introduction of uplink MIMO transmission schemes in LTE-Advanced. However, the measurement of MIMO-SAR is complex and time-consuming. In this paper, 6 unique dual-antenna mobile handsets, including both typical and novel designs, are analyzed to determine the dependence of MIMO-SAR on antenna configuration and corr
Spatial diversity is a popular multiple antenna system technique, due to simplicity in implementation. However, its application has thus far been limited to systems where the electrical separation between adjacent antennas typically exceeds half a wavelength. This is because a more compact design induces higher antenna correlation and impedance mismatch, which results in lower diversity gains. In
In this paper, a joint perception framework combining fixed and mobile cameras is proposed, which can achieve accurate real-time positioning of the mobile camera in a unified coordinate system. The system integrates VGGT for high-precision pose estimation and combines it with MASt3r-SLAM for robust real-time tracking. Alignment between different coordinate systems is achieved through rotation matr
Evaluating the user experience is often done in a laboratory. Methods for observing what happens in the wild are nonetheless being employed because they bring results that the traditional methods of evaluation do not yield. In this paper we describe and discuss methods used at our lab for understanding the mobile user experience. These methods range from quantitative to qualitative evaluation, and
