- KonferenzbeitragHow-to interact with a map application on a heavy rugged tablet PC when both hands are needed to hold the device(INFORMATIK 2012, 2012) Coskun, Tayfur; Grill, Claudia; Benzina, Amal; Artinger, Eva; Klinker, GudrunThis paper presents the second iteration of developing scrolling concepts for a digital map on a rugged tablet pc which can be used while holding the device in both hands. This map application is intended to be used during a Mass casualty incident (MCI) by the Ambulant Incident Office (AIOs). In the previous and first iteration the shortcomings of the developed concepts were identified and eliminated. The goal of the second iteration is to find out if the enhancements of the concepts work and to compare the elected two concepts - An enhanced Minimap and the so called Radar- Joystick. The evaluation results show that some features and functionality offered by both the enhanced Minimap and the Radar-Joystick concepts are accepted and positively rated, while other are confusing to the users. For this reason, we suggest to use a combination of both concepts and limit the functionality of the Minimap to emphasize the features which were rated as helpful and useful by the target group.
- KonferenzbeitragIs It possible to interact with a handheld device while holding it in both hands?(INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 2, 2010) Coskun, Tayfur; Nestler, Simon; Artinger, Eva; Benzina, Amal; Klinker, GudrunIntuitiveness, attractiveness and efficiency are in general important characteristics of high quality User Interfaces (UI). In the case of a Mass Casualty Incident (MCI) and other life threatening situations good user interfaces are essential as every second counts in these time-critical situations. Finding the best way to interact with the system is a challenge with many open issues. Therefore, it is essential to test different UI alternatives to determine important usability issues as those mentioned before. This paper focuses on the research question how patients can be selected on a map application which runs on a rugged tablet PC. A rugged tablet PC is in general heavy because of its robustness, which introduces a new special requirement in addition to the existing UI requirements. The implementation and the evaluation of the UI alternatives presented in this paper were performed within the scope of the SpeedUp project1.
- KonferenzbeitragUser-centered comparison between classical and edge interaction on a heavy rugged tablet PC used in MCIs(INFORMATIK 2012, 2012) Han, Gel; Coskun, Tayfur; Artinger, Eva; Benzina, Amal; Klinker, GudrunRugged tablet PCs used in sensitive situations and areas are different from the commonly commercialised handheld devices. Two different interaction techniques with a rugged tablet PC are evaluated. Two groups of users had to solve some tasks while interacting with the tablet user interafces (UIs) in a simulated Mass Casualty Incident scenario. This study compares two types of interaction with the tablet PC: 1) Classical interaction: The user while holding the tablet with one hand is interacting with the other hand 2) Edge interaction: The user is holding the tablet in both hands while using the thumbs for the interaction. The user study results for both interaction techniques reached comparable usability scores. Furthermore, the edge interaction technique shows better results for the fatigue and the exhaustion factors. This suggests that the edge interaction is more accepted in fatigue scenarios, but adjustments concerning usability have to be considered.
