The possibility of using virtual environments instead of real field or laboratory environments is a promising research field. However, before virtual environments are able to replace the traditional environments the differences between the methods must be worked out. We take up on previous studies which compared different real and virtual environments concerning presence and usability and expand the...
Contextual interfaces gain more and more importance within the last years. Numerous research programs that address the term context have been established, each focusing on context from their own point of view. The Christian Doppler Laboratory on Contextual Interfaces has been founded with different goals in mind. The first goal is to elaborate on the definitions and foundations of the term context...
For various VR/MR/AR applications, such as virtual usability studies, it is very important that the participants have the feeling that they are really in the environment. This feeling of “being” in a mediated environment is described as presence. Two important factors that influence presence are the level of immersion and the navigation method. We developed two navigation methods to simulate natural...
This paper reports about a pilot study of a social media platform, based on Microsoft SharePoint 2010 within a large international company, having different sites in Europe, Asia and the US. The platform should enhance the communication between departments and interdepartmentally. The goal of this pilot study is to accompany the introduction of this social networking tool in order to increase acceptability...
This paper reports about a User Experience (UX) study on industrial robotic arms in the context of a semiconductor factory cleanroom. The goal was to find out (1) if there is a difference in the UX between robots used over years with a strict security perimeter (robot A) and a newly installed robot without security perimeter (robot B), and (2) if the UX ratings of the new robot change over time. Therefore,...
This paper reports on the analysis of video footage of a human-robot study in public place regarding context factors that significantly influence the interaction. A coding scheme was developed and then used to analyze the footage. To ensure the validity of the coding, the footage was coded independently by two students and afterwards the Cohen's Kappa was calculated to ensure the intercoder reliability...
Usability inspection methods like cognitive walkthroughs and guideline-based evaluations of robotic systems find more and more usage in the design of human-robot interaction. However, due to the fact that robots can be used in a variety of different scenarios, applying these methods to robots is rather difficult. Expert evaluation methods like heuristic evaluations thus need a methodological adaptation...
This article reports on the results of a user study that investigates the perceived usability of naïve users conducting two navigation tasks with the HOAP-3 robot. In this user study, the robot was controlled via a Graphical User Interface (GUI) that enabled the users to navigate the robot in the physical environment. The main goal of the user study was to gain insights on the question if users assign...
Effective collaboration between robots and humans is not only a question of interface design and usability, but also of user experience and social acceptance. To investigate these aspects for Human-Robot Collaboration with the HRP-2 robot, two video-based focus groups enhanced with “creative stimuli” were conducted. The following research question was addressed: “Is the HRP-2 robot perceived differently...
