Mobichart for modeling mobile computing tasks

We discuss the specialty and the limitations found in the mobile computing environment to motivate the reader on the necessity of having methods for developing mobile computing applications in the object oriented paradigm. It is shown that existing specification models, like Objectchart, do not model effects due to location awareness and other typical phenomena, like hands-off and hands-on. We previously introduced Mobichart, a notation to specify mobile computing applications (Acharya, S. et al., Proc. 36th Hawaii Int. Conf. on System Sciences, 2003). We show that Mobichart can address the drawbacks of Objectchart and can be used to model mobile computing applications.
