Item10,000 Steps a Day for Health? User-based Evaluation of Wearable Activity Trackers( 2018-01-03)We present the results of a survey on perceived quality and service acceptance of activity trackers with a focus on country-based differences (US and Germany). The mutual influence of perceived service quality and service acceptance is being investigated. A new research focus based on activity trackers is the topic of medical health funds. Are users ready to share activity data with health insurance and expecting rewards in return? This study (N=803) supplements previous research which is mainly based on small sample sizes or qualitative results. Our research model is based on the Information Service Evaluation (ISE) model which includes common models such as TAM and UTAUT. Results show that aspects such as Fun, Gamification, Impact and Usefulness are very important regarding activity tracker use. Furthermore, user’s opinion on the support of medical healthcare funds and reducing medical fees is rather positive and significantly differentiates between US and German participants.
ItemThe Use of Emoji in Electronic User Experience Questionnaire: An Exploratory Case Study( 2018-01-03)Emojis are a growing phenomenon that have gained popularity in the digital era. However, little research exists on their use; a notable absent topic is the adoption of emojis in user experience questionnaires (UEQs). This study draws on semi- structured interview data from 31 participants to understand how emojis affect the experience of filling out UEQs. The data analysis reveals two key categories regarding participants’ experiences: advantages and challenges. This research contributes to the existing literature by presenting a detailed exploratory case study of user reactions to emojis in the context of UEQs.
