Introduction n n Java 3 D Object communicates with Waba Application on PDA over Wireless TCP/IP socket Waba provides Java-like programming environment to PDA Scientific Visualization

Architecture PDA Application send control request over socket Socket (over Wireless LAN) Server Get request and change the property of Java 3 D object Scientific Visualization

Waba n n n Waba programming, which specially designed for smaller devices, is strictsubset of Java Language. Waba is created by Wabasoft and has no connection to Sun Microsystems. Comparing to KVM from Sun, it has more reliability and larger developers group now. Scientific Visualization

Waba: Pros and Cons n Pros: n n n Efficiency: It is small enough to fit less powerful PDA Performance: Waba shows better performance than KVM Portable: Platform independent Scientific Visualization

Waba: Pros and Cons n Cons: n n n Weak support of GUI, Events, and Exception No Thread Limited Communication Programming Environment (Byte Buffer) Scientific Visualization

Future Study n The Framework: n n Visualization module register to Java Framework/Broker and it waits Waba Clients requests Make an API to set up the protocols between Controller and Object Broker, between Broker and Waba Client Scientific Visualization
