Smartphones and other mobile devices have fundamentally changed patterns of Internet use in everyday life by making online access constantly available. The present paper offers a theoretical explication and empirical assessment of the concept of online vigilance, referring to users' permanent cognitive orientation towards online content and communication as well as their disposition to exploit these options constantly. Based on four studies, a validated and reliable self-report measure of online vigilance was developed. In combination, the results suggest that the Online Vigilance Scale (OVS) shows a stable factor structure in various contexts and user populations and provides future work i…
Estimation techniques to measure subjective quality on live video streaming in Cloud Mobile Media services
2018
Abstract The adoption of smart phones, the increased access to mobile broadband networks and the availability of public cloud infrastructures are aligning to the next generation of truly ubiquitous multimedia services, known as Cloud Mobile Media (CMM) services offering mobile video. Nevertheless, due to an inherit higher and variable end to end delay mainly as a result of the virtualization process, new challenges appear. One challenge is given by live video streaming applications when trying to keep a good Quality of Experience of the delivered video, measured in terms of a subjective video quality metric, named Mean Opinion Score (MOS). Our goal is to estimate and predict this subjective…

The Screen Is Yours—Comparing Handheld Pairing Techniques for Public Displays
2013
Whereas mobile devices have been heavily investigated as remote controls for distant displays, research on the fundamental first step, the pairing with the display, is scarce. In a comparative user study with 31 participants we evaluated five potential pairing techniques concerning their performance and acceptance for connecting to a public display and gained insights into the general requirements for pairing techniques in this special usage context. Besides four established mobile interaction techniques (touching an NFC tag, capturing a QR code, scanning, and manual input), our study considered a recent appropriate pairing technique called display pointing, which allows passers-by to conne…
News Consumption in the Mobile Era
2014
Mobile devices allow users to keep ubiquitously connected to the internet. Consequently, they change the reception of information by faster access, greater timeliness, and new media usage contexts. At the same time, many traditional media organizations already produce content for mobile websites and apps in line with cross-media strategies. Reflecting severe structural changes in the journalism market, they are hoping to manage the digital transition successfully by mobile publishing, (re)gaining especially the digital natives. Referring to the media repertoire approach, we examine the role of mobile devices on two different levels. First, from a technical point of view, we consider the pla…
Gestural and audio metaphors as a means of control for mobile devices
2002
This paper discusses the use of gesture and non-speech audio as ways to improve the user interface of a mobile music player. Their key advantages mean that users could use a player without having to look at its controls when on the move. Two very different evaluations of the player took place: one based on a standard usability experiment (comparing the new player to a standard design) and the other a video analysis of the player in use. Both of these showed significant usability improvements for the gesture/audio-based interface over a standard visual/pen-based display. The similarities and differences in the results produced by the two studies are discussed
A multimedia approach to the efficient implementation and use of emergency plans
2004
Because of the complexity of emergency procedures, the stressful situations during which they're executed, the emergency plan must be meticulously designed so that safety managers can quickly find needed information. Regardless of the complex procedures it describes and the trying situations where it would be used, the plan's success is always measured by how effective the evacuation is. Thus, safety-conscious organizations continually try to improve their emergency procedures and the way they present them in the emergency plan. Integrating incoming information during an emergency and correlating this information with the plan's procedures is a manual task for many safety managers. The dang…
Using Prototyping in Authentic Learning of Human-Centred Design of Mobile Apps
2017
Recent advances in mobile technology have seen a sharp increase in the number of mobile applications across various application domains. The challenge remains that many software development teams may lack appropriate competences to design usable and human-centred interactive systems. This can negatively affect the usability and the user experience. In this article, we present how to learn the human-centred design process using an authentic learning approach. Students need to investigate, discuss, construct new knowledge and apply theoretical concepts to address real world problems. The main purpose of authentic learning as a pedagogical approach is to position the subject of study into a re…
