Most adults do not engage in sufficient physical activity to maintain good health. Smartphone apps are increasingly used support but typically focus on tracking behaviors with no for the complex process of behavior change. Tracking features all users, and could better reach their targets by engaging users reflecting reasons, capabilities, opportunities Motivational interviewing supports this active engagement self-reflection self-regulation fostering psychological needs proposed...

In contrast to the rather network-centric notion of Quality Service (QoS), concept Experience (QoE) has a strongly user-centric perspective on service quality in communication networks as well online services. However, related research QoE so far largely neglected question how operationalize differentiation and provide corresponding solutions tailored end users. this paper, we argue that introduction Level Agreements (ELA) QoE-enabled counterpiece traditional QoS-based (SLA) would key step...

In contrast to traditional QoS-based charging, charges for QoE (Quality of Experience) play a double role both as part the evaluation context and counterpart user's willingness-to-pay service quality. To further investigate this link between pricing QoE, we combine some unexpected results from empirical quality perception experiments with socio-psychological theory cognitive dissonance. With approach, are able explain influence active user decisions on QoE. Moreover, economical implications,...

Studying the connection between QoE and QoS its implications for network content providers has yielded a couple of well-established experimental approaches. However, research in this field mainly neglected economical aspects user trials. This paper describes evaluates an extended setup to investigate willingness-to-pay enhanced video quality inferred from parameters. The results confirm that our realistic provides valid indicating suitability upcoming studies bringing together.

Despite the fact that novel QoE based charging mechanism are vitally needed, complex interrelation of payment and quality perception has been examined only marginally so far. In this paper we want to describe a comprehensive experiment which investigates intricate interplay content selection, decisions & evaluation strategies in context video on demand scenario. Beside depicting methodological challenges providing recommendations for further empirical work, also compare current findings with...

Counteracting economic challenges in the network industry partially resulting from enormous traffic growth rates and absence of successful Quality Service (QoS) mechanisms practice, we propose a novel concept centering price quality differentiation on customers' perceptions, i.e., Experience (QoE). By fundamentally building known Paris Metro Pricing (PMP) iteratively integrate pricing with QoE aspects. Our also cardinally incorporates interests users, Internet Providers (ISPs) offering...

Within the current paradigm change from Quality-of-Service (QoS) towards Quality-of-Experience (QoE), question of how to charge for QoE is widely neglected in research community despite its obvious importance. In this paper, we present and analyze a fixed point model which specifically reflects double role prices, i.e. as regulating factor demand size at same time part QoE-based user context. The validated through comprehensive trial results allow interesting insights into temporal behavior...

Strongly rising interest in Quality of Experience (QoE) research together with the current economical struggle Network Service Providers (NSPs) are about to lead towards monetization QoE overtaking outright quality optimization importance. While there is still a significant lack quantitative studies for backing QoE-based charging recommendations, present work presents results and conclusions from recent empirical user study explicitly measuring maximum willingness-to-pay end users High...

While with traditional QoS-based charging the pricing structure mainly reflects delivered QoS in order to regulate demand, role of service prices a Quality Experience (QoE) context is more complex. Amongst others, charged price may addition have direct impact on user's

Since its early beginnings, e-mail has been one of the most successful Internet services as it was first to offer global, asynchronous and almost instant message delivery. However, at same time not designed with strong security considerations in mind, leading various problems related unsolicited messages. In order mitigate this situation, since mid 2000s, domain-based authentication mechanisms have standardized deployed which mostly rely on their specific entries DNS. our present paper, we...

Smartphone-based applications are increasingly being used to combat unhealthy habits resulting in obesity or reduced physical mobility. In turn, gamification has been identified as a useful tool motivate individuals towards behavioural change. However, both health professionals and game developers currently working on island solutions addressing individual problems due the lack of efficient frameworks enabling cooperation this domain. This resulted large number mHealth apps, each using...

While the network quality research has been oscillating between user- and technology-driven viewpoints, evolution of a utility-centric perspective is still good way off. Today, not only insufficient data exists on market figures, but also user's usage appreciation across service types test ranges. Filling those gaps, present work presents novel model, mainly constructed around existing empirical Quality Experience (QoE) materials, which approximates both ISP user utilities. A focus set case...

While for offline business models it does not seem necessary to reiterate the close relationship between quality and price, Internet services quality-based, i.e., Quality of Experience (QoE), customer-centric pricing is non-trivial. As insufficient data exists today successfully commercialise QoE, this paper collects integral empirical Willingness-To-Pay (WTP) case online video services. This work reproduces extends a previous study in two dedicated campaigns Austria Finland. The QoE WTP...

Examining monetary aspects related to QoE research, e.g. as bias, requires specifically defined empirical testing and data analysis routines. This paper presents an advanced setup for investigating the impact of purchasing behaviors in interactive Video-on-demand scenario, and, based on lessons learned from previous current experiments, provides a set recommendations further research this direction.

Complementing the current paradigm change from QoS to QoE, we address fundamental QoE charging issues for Internet services an end user perspective. Here, key arise gaps of different information contexts involved, which have be managed when introducing a product. Hence, this paper analyzes double role prices quality perception as well impact on demand with help fixed point model. Our model is consistent real-world behavior that observed during comprehensive trials video services. Based these...
