Tutkimus kosketusperäisen vuorovaikutuksen käyttäjäkokemuksesta NFC teknologiaa käyttävillä matkapuhelimilla

User experience has become a trend in the HCI field during the last ten years. Despite all the fuzz around the concept of user experience, developing the methodology for studying other than traditional usability aspects is in progress. New technologies and technological environments offer new possibilities for human-computer interaction. Using more versatile interaction techniques and modalities in human-computer interaction, it can be closer to human-human interaction and offer more natural and efficient ways to interact. Near-field-communication (NFC) technology has been predicted to be one of the leading technologies in the 2010’s for payment and ticketing applications. NFC technology offers possibilities to exchange data by bringing two NFC compatible devices close to each other. This is called a form of touch-based interaction. This thesis aims to broaden the scope of user experience research on touch-based interaction from the traditional usability aspects to hedonic and emotional aspects of user experience. Two studies were conducted in order to explore the user experience of touch-based interaction and to experiment novel methods and metrics for measuring and identifying user experience. The first study was a laboratory experiment with an electronic program guide for television in which user experience of speech, gesture and touch-based interaction were compared. The second study consisted of two group sessions that aimed to create novel use cases for the touch-based interaction with NFC enabled mobile phone and to explore user experience of the interaction. Existing methods were adapted and developed further to suit the specific context of this work. Touch-based interaction is efficient and novel interaction technique that can stimulate and bring positive user experiences to the users. Thus, it should be considered as one possible interaction method when novel technical environments are designed. Touch-based interaction seemed to be superior compared to speech and gesture in the laboratory tests. Especially the efficiency, robustness and stimulation as novel interaction method were found to be superior. /Kir1
