Designing interactions using OAI model: A new interface modeling paradigm

Human Computer Interaction (HCI) based interface modeling techniques can be employed in designing interactions. They provide complete mechanism for the design of an interactive interface in analysis and design phases of interface development. Interface design using these techniques incorporates usability and utility aspects. Object Action Interface (OAI) model is an interaction modeling technique. Our investigation revealed that existing model lacks interface responses, change of the interface states, relationship among interface constructs and mapping of sequence of actions on sequence of objects. OAI model may not be efficiently employed in designing interactions due to the investigated shortcomings. In this study we propose an enhancement in the existing OAI model. Response is introduced in the existing OAI model that will provide an improved mechanism for the design of interactions. The proposed mechanism can be employed as a new interface modeling paradigm. This modeling paradigm will lead to better interface response, improved relationships among interface constructs and better mapping of sequence of actions on sequence of objects.
