Connection and communication are heavily contingent on the internet and mobile apps, especially in this pandemic. With the blessings of Information and Communication Technology (ICT), the population of this digital era are highly dependent on several mobile applications. Undoubtedly, mobile apps have made our life easier and more straightforward, especially in the communication sector. There are at least hundreds of chat applications worldwide. Most of these communication platforms have been developed with many interactive and complex features designed mainly for the younger generation. However, in the perspective of Bangladesh, the older generation is unfamiliar and less comfortable with the concept and lacks the necessary digital literacy to use these advanced communication platforms. They frequently encounter difficulties in comprehending and using those applications. Thus, the authors described human-computer interaction (HCI) and briefly discussed some of the design issues from older adults' experiences in this report. Furthermore, a suitably designed chat application was  proposed based on understanding the challenges faced by the elderly. With a user-centered approach, the design emphasizes simplicity and minimalism, making it easier for the elderly to communicate through mobile technology.

Murni Mahmud, International Islamic University Malaysia (IIUM)

Murni is a researcher in the field of Human Computer Interaction (HCI) and User Experience (UX). She is interested to research in the area of interaction design evaluation methods, usability and accessibility of website user interfaces; usability and accessibility of Information and technology tools/software for elderly and people with special need and storytelling. While enriching her knowledge in HCI and UX, she is interested to research in use of Information Technology and Information Systems; the usage of communication and interaction tools. She is also exploring into the research area: Electronic Government and Mobile Government, Virtual Reality and Neurofeedback.  She has completed several research grants, which include Evaluation of Islamic Website, E-government portal evaluation, Museum evaluation, Virtual Reality, Children Websites and learning HCI in Malaysia context. She is currently involved in consultancy projects for Designing User Experience.


She started to develop interest to learn HCI when she worked with users and computers interfaces during her first job at Exxon-Mobil, Malaysia.  She received formal exposure to HCI research during her postgraduate study; specifically exploring and learning various interaction design evaluation methods. She has designed and conducted several HCI experiments for evaluating website interfaces, input devices, acoustic input controls and mobile phone. She dealt with various user groups from young to older users. In the experiments, she conducted questionnaires, interview, think-aloud methods and focus group
