Description
Recently, smartphones had big success and the download-numbers as well as the number of App's themselves nearly seem to explode. This thesis provides an insight about the Android-System itself, related studies and actual developments in the field of smartphone-usage. Therefore, a universal experience-sampling questionnaire tool Fragebogen is extended with required functional- ity. It should help researchers to gather suitable information about situations and circumstances affecting App-usage. Additionally, the tool enables developers to gather reliable feedback about strengths, weaknesses and possible suggestions of improvement about their Apps. First application for Fragebogen takes place in a 14-day field test, examining usage of the official Wikipedia-App. This serves as a natural test environment for Fragebogen and generates a data set that is analyzed in order to compare it's results to the actual state of knowledge. Schmidt, Robert After finishing his professional education as Fachinformatiker at the IT department of Deutsche Post, Robert Schmidt studied computer science in Berlin.
