Taking an introductory course in computer vision. Wow. This is totally new stuff. Definitely excited in learning new things.
This is really cool. Finally 3D audio is being implemented into mobile devices. This iPhone app uses screen gestures and the accelerometer to control your music library. The iPod music library was made available to third party apps in the 3.0 SDK. So this is opening great things for developers. And I’m guessing Apple did this so that they can quickly buy up new innovative technologies and implement them into the iPod music player app itself.
Recently made the dive in. The tools are relatively simple to use. Xcode, Interface Builder, and Simulator are quite intuitive. Objective-C took a while to get used to. But it’s not rocket science. Learning/tutorial-ing from a variety of places. The Stanford course has full video lectures on iTunes U. (But they recently took down all the the pdfs because the new semester will start in a vew days.) I like the course because I think Apple employees or affiliates teach it. So they actually can explain the design philosophies. The official Apple developer forums/websites are not complete. But they help. iCodeBlog.com also has some excellent tutorials.
Next thing to do. Actually get at least an iPod touch.
Did some literature survey of the area today. This group in Glasgow is doing some amazing work. Check them out: http://www.dcs.gla.ac.uk/~stephen/
I recently discovered a third-party function in MATLAB that draws arrows in figures. It’s quite versatile. It was a very helpful tool to finish writing a paper. Unexcitingly, it’s called “arrow.m“.

Trying to push out a submission by early December. Did some experiments by collecting RFID traces. Going to run some algorithms with those traces. Right now the research is focused on tracking. Specifically the idea is to recover a path. So I guess the idea can be classified as tracking. Also working on some cool 3D visualizations in MATLAB. More to come.
The first ever Wireless Summer school is winding down. I still find it funny that they just called it “Wireless”. They could have called it “Wireless Systems”, or “Wireless Networks” or something similar. But I guess the idea was that this was supposed to give a broad overview of all wireless theory and technologies. So just using “Wireless” covers all bases. Although it was broad, it was still quite deep in some of the sessions. Let’s hope this can continue next year. I think a week is a bit long though. Maybe three days, but with more stuff packed in each day would be better.
This technology/idea is pretty cool. It definitely is much simpler on the front-end than RFID/NFC. But the back-end required to support it seems quite burdensome. I’m not totally sure it will fly. But it’s definitely a step in the right direction.
Continuing to play with the Alien tags. Below is a picture of the tags lined up. The other picture is configuring/testing the code to draw heat maps.


Playing with the heat maps in MATLAB. They have functions automating basic heat maps. Google for more details.
