Animating notes captured during a lecture

Problem
The ZenPad electronic whiteboard captures every penstroke written during a single session. Currently, this information is used to automate the link between the writing and other recorded information captured during the lecture, such as audio or video. When notes are accessed after class, a student can select some writing and index into the audio or video stream from the point at which the gesture was created.

In this project, you are asked to develop some simple animation techniques that will redraw the lecture notes in real-time. There are a number of options you can explore. For example, you could modify ZenPad's show mode to begin with a blank board. Pressing "play lecture" will begin to redraw the gestures in the same order and speed at which they were initially drawn. Alternatively, you could have all text visible and simply draw over it in a different color. Or you could use a bouncing ball to indicate where the pen was writing but not actually redrawing the individual gestures. Background

• You need to become familiar with the ZenPad system, written in Java. You will be adding your animation features to this system, so it is likely that you will need to talk to Jason Brotherton, ZenPad's principal architect.
• You will need to know about or be willing to learn about Java threads

• You will create a modified version of ZenPad that animates penstrokes in at least one way.
• Provide all source code used to create animation
• Discuss the issues involved in getting animated penstrokes to work in conjunction with the streaming audio or video from a lecture

If you are able to integrate your system with RealAudio playback, you will be offered a full-time GRA position on the spot!
