A factorial survey study on the influence of advertising place and the use of personal data on user acceptance of Facebook ads University of Antwerp
Advertisements on social networking sites are typically unrequested messages placed in between the user-generated content. What makes users accept these ads (or not)? A factorial survey was conducted to uncover the impact of different factors related to the use of personal data (e.g., sensitivity of personal data) and advertising place (e.g., ad location) of Facebook ads on user acceptance (i.e., fairness and appropriateness) of the ...
User Adapting System Design for Improved Energy Efficiency During the Use Phase of Products: Case Study of an Occupancy-Driven, Self-Learning Thermostat KU Leuven
Tailoring products to user requirements can improve the energy efficiency without sacrificing user satisfaction. This study considers the case of an occupancy-driven smart thermostat in an office environment. Identifying patterns in past user behaviour enables occupancy prediction to control the heating accordingly. Potential energy savings and related environmental impact reductions, compared to a fixed schedule heating system, are calculated ...
Identifying and assessing Lead User ideas in order to foster ICT-innovation: case study digital TV Ghent University
This paper describes an exploratory approach to Lead User-idea identification. This issue is tackled by means of a case study regarding digital TV, an ICT-innovation currently heading for mass market adoption, but lacking in use diffusion. By means of a large-scale survey, the Lead Userness of 11.802 respondents was assessed with an open question, gauging at unfulfilled needs with regards to digital TV. This resulted in 13 unique possible Lead ...
The effectiveness of conceptual models auto-generated from a set of user stories written as BDD scenarios : a proposed study Ghent University
While agile methodologies are commonly used in software development, researchers have identified many issues related to requirements elicitation in agile projects. Some of these issues relate to the complexity of managing and understanding user stories, which is a widely used requirements specification mechanism in Agile methodologies. This research proposes the automatic generation of conceptual models from the user stories and the ...
Prototyping tangible user interfaces: case study of the collaboration between academia and industry Ghent University
Combining Occupancy User Profiles in a Multi-user Environment: An Academic Office Case Study KU Leuven
In a worldwide context, space heating is the largest energy consumer in commercial buildings; it accounts for 35% of the total energy consumed in the US. Energy efficient thermostats, that learn occupancy patterns and user preferences, have been studied in literature. However, they are oriented to single-user environments; therefore, they are not applicable in offices where several users interact, i.e. multi-user environments. To expand the ...
Lead User Identification through Twitter: Case Study for Camera Lens Products KU Leuven
Lead users are a significant segment of the user population that exhibit product use related needs that cannot be met by existing commercially available solutions. They expect high benefits from actively engaging in innovation activities. To identify lead users, researchers have looked to the Web as a potential source of lead users. This paper discusses identification of lead users on the social networking site Twitter using a validated online ...
Connecting physical activity with context and motivation: a user study to define variables to integrate into mobile health recommenders Interuniversity Microelectronics Centre
In this paper, we aim to improve existing health recommender systems by defining relevant contextual and motivational variables to recommend physical activities and collect appreciation feedback. Current health recommenders do not sufficiently include users' context and motivational theory when personalizing health suggestions. To bridge these gaps, we conducted a 21-day longitudinal user study with 36 participants using our Android app with ...
Towards predicting hexad user types from mobile banking data: an expert consensus study KU Leuven
The Hexad user types model is often used in the gamification community to tailor gamified systems. However, most often, it requires users to fill out a questionnaire, preventing an automated adaptation of the interactive system. For this reason, we explored the potential of using mobile banking data to automate the profiling of Hexad user types. In our study, we conducted an expert consensus study to research whether a group of experts (N=11) in ...
