I could install and write the sample codes using processing 1.0

Seems processing has very rich library video processing. And definitely we would need to write small pieces of code like python. It uses mostly java with slight modification that makes life even easier.

My confusion regarding rectifying Map Frames

I was wondering how to relate frames captured from Tablets and Video cameras for rectification, Michael said rectification can be done linearly with the finger tips' coordinates. But actually we wont relate or compare frames from Tablets with those of Video cameras rather we would rectify those separately. It my misinterpretation from the pipeline-sketch. Now I got it !!! We are gonna do the capturing separately. The rectification now makes sense.

Braille Reading paper from Michael

These guys used pen attached to the dominant finger of the blind person a little bit above of the blind participant's finger tip and by this way they could capture the finger trace. And one thing was interesting that they gave freedom to the participants to read or scan on their own way and this is a good lesson which we might use to get a natural finger movements of the participants. So I still believe using eye folded persons instead of real blind subjects would make difference in analyzing finger tracing behavior and letting the participants use much freedom for their finger movement would bring much real observation.

My Plan on our first Visual Team Meeting

I got one tactile map and I think we can start capturing some sample videos on our first meeting while one of us can try to act as an unsighted person. We can then make some still frames or even analyze how we can really apply the video processing. I can also bring my video camera until we get a working one with us from the media center.

Our lead Peter thinks we can try this. Lets see what we can get.

I got one tactile map from Xiangkui

I wish to bring this for the Monday's class. Using this kind of map visually impaired persons can touch the paper and feel the high ink to realize the objects on the paper. This seems very useful for unsighted people. And until I really saw it I didn't realized much how this map can be effective for blind users' navigation.

My task for Monday 04/06/2009

I would need to provide a proof of concept that processing 1.0 can be used for finger tracking. This is a java based language and seems like even we would need to use less codes than java and kinda similar like python.

I found some people talking that they could able to use processing for face detection and I hope I would find some way to use it for finger tracing.

Processing 1.0

MIT Media Lab has created one language for processing image and interactions. I believe we can use this Processing 1.0 for video capturing thing.
