As competition and the number of users increases streaming services have to pay more and more attention to the quality and the functionality of the service. This means that services have to focus on users and their wants and needs. By studying the usability and user experience it is possible to improve the quality and functionality of the services from a user point of view. This is why studying and measuring usability and user experience of streaming servi-ces is important. This bachelor\u2019s thesis\u2019 purpose is to present factors and measuring of usability and user experience of streaming services. The research questions of this thesis are: 1. What are the factors of usability and user experience in streaming services? 2. How are usability and user experience in streaming services measured? This thesis was executed as a literature review. QoE and QoS are terms that were used in the resource literature when speaking about usability and user experience of streaming services. These terms were much used when dealing with the research questions. The results of this thesis indicated that many factors have an impact on usability and user experience in streaming services. These factors could be divided into subjective and objective factors. The most essential factor was stalling of video or audio and the waiting time that results from it. The measurement of usability and user experience in streaming services could be divided into ways of measurement that were subjective, objective and the combination of both. Subjective way of measurement was the most used and accurate way. It was primarily executed with test users who used the service and evaluated it from their own perspective. In objective way of measurement different kinds of technical parameters like bitrate were measured. By combining these ways of measurement it was possible to execute multidimensional measurements. Standardized factors or measures were not found in this thesis. Because of that more research is needed.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Severi Vihavainen (semaviha) on 2016-12-02 13:19:26.616338.
