Last week I did a lot of writing. This week has been more of a "plan ahead and think back" week. It is time to plan the development of the new system. The most important thing for now is to limit this to a task that can be completed in the limited timeframe of the thesis.
On the writing side of things I have continued my review of existing systems, but also the writing about the fundamental technologies that they rely upon (GPS, WLAN, RFID, computer vision).
One thing to remember is that a location can simply be defined as any kind of "fingerprint" associated with it. This is easy to forget when there are such obvious and intuitive techniques such as GPS. I have seen this done by looking at colour histograms of a scene, or using a multitude of basic sensors to obtain a "fingerprint" of a location. Very interesting.
