A study of human-computer interaction for mobile devices - A case study of “black berry”

Designs in human-computer interaction (HCI) aim to create interactive products that are easy and enjoyable to use. However, owing to the multidisciplinary nature of HCI and the different value systems of interface users from various backgrounds and experiences, it is highly challenging for designers to create applications which are usable and affordable to such a heterogeneous set of users. Nowadays, more and more people are heard complaining about the bad interaction design of mobile devices. Is this problem caused by the bad design of products or by the users' ignorance of the logics of human machine interaction design? The aim is to explore the human-computer interaction challenges in designing applications in both hardware and software for mobile devices. It also makes an attempt to investigate the principles for designing mobile interfaces that result in greater user acceptance and figure out possible solutions to the problems with interaction designs for mobile devices. The work described in this paper concentrates on examining the HCI features required for a successful PDA (Personal Digital Assistant) for use in mobile computing. This paper also presents a case study methodology of research followed to analyse the problems during initial release of the product and the resultant rectifications in the new model.
