After the demonstration of the RFID tags on Monday I have been able to make an informative decision. There will be a high chance of them not working as there were connection problems from only very short distances between one sender and one receiver. The interference from people or objects also had a large impact on the distance that was being calculated. The price of one receiver would cost $500 and the sender $50. This would be too high of a cost for our budget as we would need at least 3 receivers for this to work.

Today I changed to another method of tracking using a
Linux system and what would be connected to 3 cameras and programmed with C++. The creator made a very precise and
working tracking system in the space he used. He was able to use at least 3 cameras to get a 3D position of the people. After installing Linux and spending half a day looking at just the first steps on how to create this, I began to realise that it was looking impractical to be able to follow and recreate this tracking system that has taken the creator 15 months to create.

Upon looking back over all the different methods we have had on creating the indoor tracking I have seen this project too much focused on the tracking part. I will look at how we can develope this aspect of our project without it becoming the main focus. We still need to make sure this is a triggered unity project using humans that are put into their perception of being an ant, rather than an indoor tracking project.
