| Design of a mHealth App for Gestational Diabetes Mellitus Management and Education in Bangladeshi Women | Gestational Diabetes Mellitus (GDM) is a type of diabetes that a woman may experience during their pregnancy period. According to the World Health Organization (WHO), one out of ten pregnant women around the world tend to have GDM and may have a risk to both mother and child of having type two diabetes. Studies reported that around 35% of Bangladeshi women have GDM. For most of the women in Bangladesh GDM is unknown and its education is essential for the women who are pregnant or planning for pregnancy. Although there are some apps available online, due to language barriers it is not in the limelight, so we have designed an app which not only eliminates the language barrier but also manages and educates the women for pre and post-pregnancy GDM-related problems. Our app has features of keeping track and control of food intake, water intake, physical activity, reminder, GDM education, chat forum in social community, game. The features in the tool are HCI based which are known by usability testing, it will help pregnant women with GDM to keep a track of their health and blood glucose level and improve their lifestyle in a better way. |
| Stress Management mHealth Application for Healthcare Professionals in Bangladesh Stress Management mHealth Application for Healthcare Professionals in Bangladesh | This study explores the development of a usercentered mobile health (mHealth) application aimed at managing stress among healthcare professionals in Bangladesh. The objective of this study was to identify key stressors, coping strategies, challenges during managing stress, the role of technology, and users’ requirements through the survey. Then, based on the findings of the survey we conceptualized an mHealth app that addresses these challenges and help professionals to manage their stress at work. The method includes designing and disseminating a questionnaire, analyzing the data to inform the application’s features, and creating a high-fidelity prototype. The results show that high workload, patient and family pressure, and staffing shortages are major stressors while social support, taking short breaks, and time management are some of the effective strategies for coping with stress. On the other hand, participants demanded for features like guided sessions for meditation, personalized stress management plans, real-time health tracking and expressed willingness to use a smartwatch-based mHealth real-time stress monitoring app. Evaluation of the prototype demonstrated its potential effectiveness in stress management. The study concludes that such an mHealth application could significantly aid healthcare professionals in stress mitigation. We plan to improve the app further based on user feedback. |
| Smart Emergency Healthcare Service System Based on IOT and AI – A Model based Framework | This work presents StaySafeAI, an advanced Android application designed to enhance emergency healthcare through the integration of the Internet of Things (IoT) and Artificial Intelligence (AI).

In this study we conduct a survey to understand the views and practices among Bangladeshis. Understanding the user needs and mobile app benefits we are proposing a simple solution for the people of Bangladesh. Just simply providing physiological information allows users to know their nutritional needs and make grocery choices accordingly. Among 72 participants 75% wanted this kind of solution and among 10 testers all of them liked using our system. |
| ShoroSonket: A Vision Transformer based Bengali Sign Language Interpreter | Effective communication is a fundamental human right, yet hearing-impaired individuals often face significant challenges in their interactions with the non-sign language using population. In this context, we present a novel web app that leverages state-of-the-art machine learning techniques to interpret Bengali sign language gestures into text, bridging the communication gap between sign language users and non-sign language users. Our approach employs a Vision Transformer (ViT) model, trained on a comprehensive dataset, to accurately capture the spatial and temporal intricacies of sign language gestures. The model achieves an impressive accuracy of 97.41%, with high precision, recall, and F1-Score, making it proficient in real-time sign language interpretation. The web app’s usability was validated through extensive testing, resulting in an average System Usability Scale (SUS) score of 82.5, signifying strong user satisfaction and ease of use. Participants praised its user friendliness, ease of learning, and integration of functions. This initiative not only improves communication for the hearing impaired but also promotes accessibility and inclusivity in society. In future work, we aim to expand our model’s capabilities to encompass various sign language dialects. Our project exemplifies the potential of technology to empower and enrich the lives of individuals with hearing impairments by providing them with a powerful tool for effective communication. |

Our project aims to create a user-centered virtual conversational Agent-Based dengue dashboard, helping users in Bangladesh access accurate information, symptom tracking, and guidance during dengue outbreaks. Our main objective is to create a user-friendly virtual platform with an AI-driven chatbot to help educate and guide dengue patients and caregivers in Bangladesh. We also need to design the platform with a focus on the user’s needs to make it effective and easy to use, and we also need to continuously gather user feedback and make improvements to the system through iterative evaluations. The user-centered approach being used in this project is intended to solve the dengue problem in Dhaka. User personas facilitate the development of chatbot interfaces and virtual dashboards by integrating a range of viewpoints obtained from focus groups, interviews, and surveys. An effective and culturally appropriate set of tools is the goal of the iterative design process, which is guided by user input and health data. Encouraging preventive and health monitoring, the chatbot uses strong natural language processing (NLP) technology to deliver individualized information and help. Tests conducted in the actual world will be used to gauge the project’s efficacy and cultural fit. The project’s objective is to empower people in Bangladesh to prevent dengue by working together with stakeholders and adhering to ethical principles such as user data privacy and accessibility |
