- TextdokumentEmpowering Safety Technology for Women’s Solo Journeys: Insights from a Story Completion Study(Mensch und Computer 2023 - Workshopband, 2023) Jeon, Hyesoo; Ebeling, Jule Sophie; Osipova, MargaritaThe growing trend of female solo travel has brought attention to the unique risks women face while travelling alone, such as sexual harassment and physical threats posed predominantly by men. Therefore this study explores how technology can be leveraged to improve solo women travellers’ physical safety. Through a series of workshops using the Story Completion method, 14 women with experience travelling alone shared experiences and ideas regarding concerns and chances of using safety technology. The results obtained through thematic analysis showed the need for devices that converge technological and non-technical assistance to address the threats women face when travelling alone, utilising authentication, location detection, and sensing technologies.
- TextdokumentExit Violence: Comparing Usability of Physical and Visual Alarm Buttons in SOS App in the Context of Domestic Violence(Mensch und Computer 2023 - Workshopband, 2023) Sarkar, Nabanita; Marra, Konstantina; Osipova, MargaritaThis study investigated the effectiveness of SOS apps in supporting domestic violence victims, specifically examining the activation process through visual user interface (UI) and physical UI. Using a roleplay method and interviews, participant preferences and behaviours were assessed. Participants used an Android phone with an SOS app, activating it through either visual UI or physical UI. While participants displayed similar behaviours and visually focused on the screen for both methods, a strong preference for the physical UI was observed. Despite no significant behavioural differences, participants expressed higher satisfaction and perceived efficacy with the physical UI.
- KonferenzbeitragHigh Accuracy GPS Antennas in Educational Location-based Augmented Reality(Proceedings of DELFI Workshops 2022, 2022) Osipova, Margarita; Das, Sanghamitra; Riyad, Peter; Söbke, Heinrich; Wolf, Mario; Wehking, FlorianIn location-based augmented reality (AR), the augmentations depend on the geolocation. Location-based AR might be used in higher education for enabling authentic learning experiences. However, the positioning accuracy achievable with GPS receivers built into off-the-shelf mobile devices has been shown in previous studies to be suboptimal for a subset of learning scenarios. Accordingly, in this comparative study, we investigated whether high accuracy GPS antennas are capable of achieving higher positioning accuracy, which also may improve the learning experience. Specifically, a mobile geographical information system (GIS) client (AugView) was used to visual-ize pipes and manholes in the underground. Participants were tasked with recording a local sewer system using the GIS client and subsequently visualizing the network using the GIS client’s AR mode. The experimental group (N=8) used an external GPS antenna, while the control group (N=8) relied on the standard GPS receivers of the mobile device. Usability was assessed using the Post-Study System Usability Questionnaire, learning outcomes were measured using pre- and post-test. In addition, semi-structured interviews were conducted with all participants. As a result, usability and learning outcomes were found to be better for the experimental group, but deficits in accuracy of the visualizations were also found with the GPS antenna. In particular, the time delay that must be waited until a high accuracy is achieved in case of non-uniform motion has to be noted. However, this time delay can be compensated for with appropriate learning scenarios design. In summary, high accuracy GPS antennas seem being beneficial to learning scenarios but require careful context-spe-cific prior evaluation.
- WorkshopbeitragSmart City for women’s safety: exploration of the problems and solutions through Co-Design(Mensch und Computer 2022 - Workshopband, 2022) Osipova, MargaritaSmart City technology is a rapidly developing field that aims to solve city-problems through technological modernization of the environment and society, including safety and security of citizens. The level of safety of the urban space influences inhabitants’ mobility levels, meaning that unsafe places restrict citizens from traveling there in general, by themselves, or at specific time of the day. These usually affect female citizens more, as they are likelier to be exposed to unsolicited dangerous attention –including sexual context–, while being less bodily able to protect themselves. This study investigates the requirements of women for future urban technological solutions through a Co-Design approach. Covering topics from the fears that women experience to the solution ideation, this work contributes to a better understanding of women's perspectives on the use of Smart City technology for safety and highlights the benefits of using Co-Design method in the research of topics alike.
- TextdokumentUnleashing the Power of Wearable Technology: Enhancing Health and Adaptation for International Students in Transition to Germany(Mensch und Computer 2023 - Workshopband, 2023) Pankhuri, Pankhuri; Aghamohammadian, Nasim; Osipova, MargaritaInternational students encounter many challenges while relocating to a foreign country that impacts their mental and physical well-being, creating a cumbersome adaptation process within the new academic and cultural environment. We conducted a series of participatory design sessions with 20 participants from 10 countries to understand international students’ most pressing challenges during their transition to Germany and involve this population in the design process. We revealed the envisioned features of wearable technology as described by international students. Our findings indicate that the continuous accessibility characteristic of wearable technology can facilitate task management among students while also providing essential support for their well-being through monitoring physical and psychological parameters. Furthermore, integrating immersive technology with wearables emerged as a frequently requested addition, enhancing real-time connectivity and assisting students with navigation.
