User involvement is an important issue that is currently discuss in software development industry. This is due to the incidence of user frustration when using a software product. The literature on software development reflected that the involvement of users in all stages of user involvement in software development lifecycle (SDLC) process can contributes to the software usability. Although practitioners have agreed that user involvement in software development is very important but the extent of user involvement in practice is still unknown. This paper reports on a study that was conducted to investigate user involvement in the SDLC process. The objective of the study is to investigate the degree of user involvement in SDLC process. In the study the Human Centered System Development Life Cycle (HCSDLC) model was used as the research model. In the study a survey was carried out and 32 software practitioners has responded to the survey. The result of this survey indicated that user involvement is mainly concentrated in the functional requirement gathering rather than non-functional requirement gathering. This paper then concludes that practitioners do not involve users in the non-functional requirements gathering which then implies that users are not involved in determining the kind of software used during the SDLC process.

In the Human-computer interaction (HCI) literature, it has been recommended that user involvement and HCI considerations in the software development life cycle (SDLC) is an important mechanism for a successful system implementation. However, it is still unclear to what extend do the user involvement and HCI consideration have been adopted by software development practitioners. This paper reports the results of a survey on the importance of HCI in SDLC from practitioner perspective. The survey involves thirty two software designers. The objectives of the study are to identify the state of user involvement in SDLC and to identify the HCI elements that have been addressed. Results have found that many of practitioners involve users in SDLC, but majority are only during the requirement analysis phase. The findings also reveal that HCI elements on functionality are well addressed, however, the non-functionality elements such as cultural and affective values have not been emphasized by practitioners. The paper concludes with recommendation to further investigate on user awareness on the importance of user involvement in the software development.

Direct manipulation which was introduced in the 1990s has enriched the technological and intellectual landscape of Human Computer Interaction (HCI) where interaction style progresses from linguistic to manual interaction via graphical objects. The engagement that results in the direct manipulation activity gives rise to a new philosophy of graceful interaction. However, ever since the concept was introduced, the HCI literature does not exhibit much related work on graceful interaction. In this paper, we present a design framework for graceful interaction through the use of Laban effort theory to formalize graceful interaction design. This framework presents a theoretical proposition and practical characteristics to describe the movement qualities of graceful interaction. The framework invites and challenges interaction designers for the exploration of graceful towards aesthetic interaction.
