Nowadays usability is a major factor in developing IT-services. User interface designing is more and more user-centered as well as customizing services. It\u2019s found in many re-searches that there are five basic factors when measuring usability: learnability, efficiency, memorability, errors and satisfaction. There\u2019s not much research made of the factors affecting to usability of streaming services but in recent years the services has increased which has affected the increase of made re-searches about the topic. The results of this study are related to differences of up-to-date playback devices and connection speeds. The basic principles of us-ability must be in place to ensure reliable service. Differences in playback de-vices\u2019 screens have also affect in user interface\u2019s designing and its usability. When playing video or audio over internet, connection speed, processor power and battery power have influence on the quality of playing media. The quality of playing media impacts on user experience and satisfaction. The research re-sults answer on research questions How can services\u2019 user interfaces on internet be evaluated?, Which factors should be paid attention to when evaluating streaming ser-vice? and What are the basic principles of designing streaming service?", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Henri Dahlstr\u00f6m (hemidahl) on 2015-08-28 21:05:05.837693.
