This research studied the usability of the six most commonly used Mobile Financial Services (MFS) - (bKash, Nagad, Rocket, SureCash, Upay, and TAP) of BD, especially focusing on BD’s digitally illiterate people. We conducted both heuristic study and user study of the six applications and identified significant usability challenges, particularly for digitally illiterate users that included UI design issues, logical errors, lack of proper guidance, unavoidable faulty transactions, and difficulty in understanding the interface. We evaluated the results based on Effectiveness, Efficiency, and Satisfaction to identify those design gaps and proposed new design considerations - simplified UI design, native language support, voice assistance, better error handling, and more visual cues rather than text to ensure every user gets to utilize the full potential of these services. In future, developing and evaluating a prototype incorporating these recommendations and expanding the evaluation to include more features beyond the basic money transfer functionality could provide better insights on user behavior.

In this study, the design and development of a budget-friendly and mass-producible platform is showcased, that is capable of pro- viding facial detection, real-time contact-less temperature scanning from the forehead, RFID scan, timestamp logging, notification-based alert system along with an automated attendance system to avoid all means of contamination. To assess the functionality and usability of the proposed system, an evaluation study categorized into two sections -one for the embedded unit and the other for the web application was conducted at MIST’s AI Lab. 

Even though there’s an ongoing increase in demand, there are still not many technological developments implemented to eradicate the manual labor involved in the garments industry which is this research focused on developing a supply chain management system, incorporating Internet of Things (IoT) and promoting more human and computer interaction. The limitations of the present supply chain management systems were identified through a literature survey and to address those limitations, a Blockchain-based framework was proposed that also incorporated the Internet of Things (IoT). Then, a prototypical system (user interfaces) was developed based on the proposed framework to provide a clear understanding and applicability of the proposed framework which would ensure data security, reliability, and integrity.
