CASASviz: Improvement (1)

Here is some improvement to be implemented into our CASASviz 2.0

1)To solve the visualize the data in real time, we will use Raphel SVG library to draw the main graph dynamically. (I already tested the graph. It works very well)

2)Prafulla is working on the client cache part, which will solve us the out-of-memory problem in server.

3)We are planning to apply real-time activity recognition algorithm into our webpage system.javascript:void(0)

CASASviz Summarization 1.0

In our first version of CASASviz project, we implemented several basic functions:
(1) Visualization of residents' mobility;
(2) Visualization of Heatmap mobility;
(3) Visualization of Activity Map;
(4) Visualization of Power Usage.

There are still several drawbacks existing into our CASASviz system.
Firstly, our system generated the SVG file on the PHP server, then sent the whole file to the client side. This solution is not good one due to the limitation of network bandwidth. The system didn't work very well on my Iphone.
Secondly, If the data file we will visualize is very huge, the memory of our php server could not load so many original data.
Thirdly, although we applied google chart tool to implement power usage, it is a static image. To improve the user's experience, we will continue to develop dynamical image using dynamical google visualization tool.
