- KonferenzbeitragEmergency Alerting Through Smartphone Apps(Mensch und Computer 2022 - Tagungsband, 2022) von der Linde, Mira; Nospickel, Paulin M.; Göcke, Melanie; Thielsch, Meinald T.In Germany alone, there are more than one million active members of fire departments, relief organizations and disaster control [1]. In case of an emergency, alerting apps are being used more and more in both professional and lay contexts. Fire departments, in particular, supplement alerts of their firefighters with alerting apps. These apps send the same alarm cue to the smartphones simultaneously with the (digital) radio message receivers of the first responders. To date, an overview of the functions of such apps and their respective importance is missing. Our research fills this research gap by summarizing functions of alerting apps in an overview manner. In addition, first responders (N = 287) as users of alerting apps rated and ranked the functions in terms of their importance, the app usability and were openly asked about advantages and disadvantages of such apps. The resulting ranking enables the selection of suitable alerting apps. However, both quantitative data and responses to open questions show clear deficits mentioned by the users in the area of usability and technical requirements. This is particularly critical, since every second counts in the alerting of first responders.
- KonferenzbeitragOptimized Visualization of Building Fire Risks through Mobile Application(Mensch und Computer 2023 - Tagungsband, 2023) Jung, Norman; von der Linde, Mira; Thielsch, Meinald T.This research aims to create an app-based visualization of fire probability to enhance fire safety measures in public and cultural buildings through the integration of the Internet of Things and wireless sensor networks. We employed a two-stage research methodology: the first study (N=104) used the Kano model to identify key app features and attributes prioritized by both laypersons and experts; the subsequent study (N=507) examined the efficacy of low-fidelity interface mock-ups derived from the results of the first study, focusing specifically on how effectively fire probability information was presented. The results showed that participants prioritized functionality and effectiveness over aesthetics in such an application. In addition, interfaces with clear, organized presentations and multi-level risk ratings were found to be the most effective. In addition, the use of visual cues increased user engagement, while oversimplification decreased user interaction. Ultimately, these findings highlight the need to prioritize functionality, user engagement and ease of use in the development of fire probability systems, thereby promoting more effective prevention and mitigation strategies in public and cultural spaces.
