A considerable share of applications such as web or e-mail browsing, online picture viewing and file downloads imply waiting times for their users, which is due to the turn-taking of information requests by the user and correspoding response times until each request is fulfilled. Thus, end-user quality perception in the context of interactive data services is dominated by waiting times; the longer the latter, the less satisfied the user becomes. As opposed to heavily researched multimedia… 

The Impact of Waiting Time Distributions on QoE of Task-Based Web Browsing Sessions

TLDR
The study shows that the end-user QoE is different for different variety of delays, and concludes that, the users prefer small frequently occurring delays as compared to the long rarely occurring delays within a task-driven web browsing session.

Impact of HTTP Object Load Time on Web Browsing QoE

TLDR
This study evaluates how the delay affects the QoE when applied within different parts of the web browsing transfer, such as DNS resolution, base object and the embedded objects on web pages.

In small chunks or all at once? User preferences of network delays in web browsing sessions

TLDR
This paper presents user responses to the three different distributions of delays, occurring during shopping sessions on the Web, and finds that, the users prefer small frequently occurring delays as compared to the long rarely occurring delays within a task-based session.

Analysis of a large multimedia-rich web portal for the validation of personal delivery networks

TLDR
Initial results show that a PDN-based approach allows to significantly reduce the average latency, and this paper introduces the concept of personal delivery networks (PDNs), in which content is stored closer to the end user, at delivery caches in the edge of the core network or even in the access network.

How much longer to go? The influence of waiting time and progress indicators on quality of experience for mobile visual search applied to print media

  • 2013
TLDR
This paper studies the influence of linking two different media types, video and webpage, to the printed picture and shows that the linked content has little influence on the resulting QoE, which is found to have a logarithmic function of waiting time, similar to other applications previously studied.

User Experience of Web Browsing - The Relationship of Usability and Quality of Experience

TLDR
Interestingly, participants seem to be unable to rate the constructs usability and QoE independently from each other, and it is recommended for similar future experiments to check beforehand whether Quality of Experience and Usability can be reliably judged and distinguished by naive participants.

Users' reaction to network quality during web browsing on smartphones

TLDR
This paper analyzes the telecom traffic of smartphones passively monitored from 3G mobile network and shows the effect of network quality on the users' web behavior and finds that users generate more web traffic and transactions when the qualities of the network are both good and poor.

Associating user’s psychology into quality of service: an example of web adaptation services

TLDR
The proposed strategy takes into account the current server load and enables a mechanism for the user to evaluate whether the new response time can be accepted or not and results indicate that the proposed strategy performs well.

Waiting along the Path: How Browsing Delays Impact the QoE of Music Streaming Applications

TLDR
It is found that browsing delays have no impact on the music streaming QoE, which shows that users are able to clearly distinguish between the two main functionalities of such apps, namely, browsing and streaming, and shows that both browsing and Streaming are equally important and have to be considered when designing music streaming applications.

An HTTP/2 push-based framework for low-latency adaptive streaming through user profiling

TLDR
This work presents a framework for low-latency delivery of news-related video content, integrating four optimizations either at server-side, client- side, or at the application layer, and proposes to identify relevant content through user profiling, using proactive delivery and client-side caching to reduce the video startup time.

“Time is bandwidth”? Narrowing the gap between subjective time perception and Quality of Experience

TLDR
This paper addresses the question whether it is sufficient to reduce typical Web QoE assessment scenarios to the temporal aspects of waiting for task completion, which would allow to attribute the resulting logarithmic laws to well-known psychological insights on human time perception.

Trouble shooting interactive web sessions in a home environment

TLDR
This work has developed a three-tier system that captures in the browser the events necessary to measure the page load time, captures at the network access all incoming and outgoing packets, and correlates the measurements made at different machines.

Quality is in the eye of the beholder: meeting users' requirements for Internet quality of service

TLDR
It is shown that, while users' perceptions of World Wide Web QoS are influenced by a number of contextual factors, it is possible to correlate objective measures of QoS with subjective judgements made by users, and therefore influence system design.

A generic quantitative relationship between quality of experience and quality of service

TLDR
The IQX hypothesis is a strong candidate to be taken into account when deriving relationships between QoE and QoS parameters and is shown to outperform previously published logarithmic functions.

Integrating user-perceived quality into Web server design

Understanding the management of client perceived response time

TLDR
RLM operates as a stand-alone appliance that simply sits in front of a web server complex, without any changes to existing web clients, servers, or applications, and dynamically adapts connection setup behavior and web page content as needed to meet response time goals.

TLDR
A methodology similar in function to the Mean Opinion Score (MOS) in the voice domain is presented, and is therefore dubbed the dataMOS, which model user opinions at given bandwidths with a “slope-saturation” model that conveniently captures both the quality/bandwidth trade-off for a given task, as well as the saturation bandwidth.

Quality of Experience from user and network perspectives

TLDR
This work tries to associate on one side the correlations between various traffic characteristics measured on an operational network and on the other side the user experience tested on an experimental platform to validate how and to what extent the volumes of user sessions represent the level of user satisfaction.

Quantification of Quality of Experience for Edge-Based Applications

TLDR
The IQX hypothesis is presented, which assumes an exponential functional relationship between QoE and QoS, and the basic properties of selfish and altruistic user behaviour in accordance to edge-based intelligence are shown.

Web QoE Evaluation in Multi-agent Networks: Validation of ITU-T G.1030

TLDR
This paper presents a general system developed to evaluate QoE on IP networks, designed to be capable of emulating multi agent networks and dynamically changing conditions.
