Web QoE Assessment 1/2

Goal is to quantify impact of: -  QoS parameters -  Usability -  Design -  Device Performance

on subjective quality perception of web browsing under realistic conditions

Web QoE Assessment 2/2

Content Related Problems: §  Lack of control (Advertisments, interactive elements)

§  External sites permanently changing

§  Server and internet performance fluctuations

§  Comparability between Labs

Motivation and Goal

Content Framework Requirements

§  Locally stored §  Representative for different Content Categories

-  e.g.: News, Photo Album, Webshop, Map Services

§  Interactive Content -  Updated daily -  User interaction possible

§  Available in different languages §  Customizable design in order to mimic certain

webpages §  Customizable page weight §  Mobile derivate of the framework §  (somehow) coherent with existing Standards (Kepler)

Content Categories

§  News

§  Photo Albums

Content Categories ctd.

§  Webshops

§  Map Services

Interactive Content and Language

§  Requirement 1: Allow for realistic tasks! §  Requirement 2: Avoid user fatigue and boredom!

§  Sufficient amount of information for several Web QoE test conditions (each 2 – 3 minutes)

§  Interaction pattern must be realistic §  Up to date information is important, especially for

news pages §  Page content must be available locally §  Language should be adaptable to target audience

- 9 - © FTW 2012

Design and Page Weight

§  New web test content framework must be able to mimic different web page designs.

§  Ideally different sites could be recreated by the same framework

§  Customizable page weight. -  Emulate technical properties of existing sites àFuture proof

Coherence with KEPLER

§  The new framework should be technically coherent with the existing Kepler page in terms of defined

-  Object count and size -  Object types -  Object size distribution -  Compressible / Incompressible objects

§  Additional feature(s) -  Customizable page weight

PROPOSED SOLUTION

- 12 - © FTW 2012

FTW’s solution 1/2

§  Automatically created web pages suitable for subjective testing

-  Interactivity is ensured as pages have the same depth as the prototype page / RSS feed selected

-  Several successive web QoE sessions can be conducted as the content is ‘deep’ enough.

§  Content Framework creates web page from harvested content in the database automatically

-  Page appearance is defined via style sheets -  Page style can be easily customized -  Mobile version defined via style sheets

- 13 - © FTW 2012

FTW’s solution 2/2

§  Content: harvest information from selected prototype page through python script or RSS feeds

-  Content fed into a local database -  Freshness of content enabled by e.g. harvesting news every

day in an automated fashion -  Language selection achieved via prototype page / RSS

feeds

§  Web page categories being implemented currently -  News Page -  Photopage

Conclusion

§  Content for subjective Web QoE Tests on its way §  Following requirements are met

-  Local storage -  Decent interactivity and content ‘depth’ -  Configurable Language -  Two content categories

§  Requirements not met (yet) -  More content categories -  Mobile derivate

§  Roadmap -  Publication as part of Standardization Process within ETSI -  Release Date: 12.12.2012
