1. Wireless Applications Squeak & Croquet Bo Li Auburn University Research Spring 2006

2. Intro to Wireless Programming Make the software that run at wireless devices such as Zaurus or Palm,etc. General, the Java is used as programming language, but Squeak has some advantages: –Squeak VM is now stable. –Open Source Style Development –Portability of the Application, Squeak VM is easy to port and has ported to many platforms Our goal is to use squeak to make the program and port it to the wireless device to use.

3. Sharp Zaurus Zaurus background and OS –Zaurus is a brand name of a PDA family by Sharp.The Sharp Zaurus (SL-5500), the Linux operating system are crammed into a palm-sized package. A CF card slot allows for an 802.11 or Bluetooth wireless networking card. Why we want to use it? –It is a portable device and the squeak VM can be executed on sharp zaurus. Emulator : We need a emulator to simulate the zaurus, we can run the emulator on Linux.

4. Background of Croquet Croquet is a combination of computer software and network architecture that supports deep collaboration and resource sharing among multiple users within the context of a large- scale distributed information system. Along with providing a flexible enough framework that virtually any user interface concept could quickly and easily be prototyped and deployed, Croquet can be used to deliver compelling 3D collaborative visualizations and simulations.

5. Background of Croquet (cont.) What is Croquet good for? –Base on squeak –Base on smalltalk How Squeak runs cross- platform across Macintosh, Windows, and Linux, and the Croquet Harness in turn sits on top of Squeak.

6. Background Papers The Croquet used for Education Abstract –Graphics and dynamic items used in teaching will attract more students ’ attention. We use the croquet build the 3D program to help teach in the courses. Croquet can be used to deliver compelling 3D collaborative visualizations and simulations. It is based on squeak, and can be used cross operation systems. The squeak and croquet are all based on smalltalk. That give us some advantages when programming by both of squeak and croquet. It can also can be use for improve the quality of user inter face. Summary –The croquet basic and squeak and small talk. –How to use croquet to build 3D program for education. –How to program by both of squeak and croquet. –The oration and problem of our research.
