The widely used instant messaging systems usually incorporate the same context awareness function that displays the current status of other users. There are many prototypes of context aware instant messenger program that already being developed and being tested in order to ensure the applications are able to display the users' status in a more reliable and accurate manner. However, the availability indicator provides by those instant messengers only useful for users who are planning to have communication with other users. This kind of context aware does not help users to use the instant messaging systems for another purpose such as to schedule an appointment with one of their contact list. The design of a Context-Aware Instant Messenger with Integrated Scheduling Planner system is proposed to cater the problems. The solution application is designed for all computer users especially for the staffs in organizations and universities students which will enable them to do any appointment via instant messaging system. © 2012 IEEE.
