One thing I found interesting is that computers dont really “see” things the same way we do. When we look at someone, we can understand that they are a person, what they are doing, and what is happening around them. A computer, on the other hand, is basically looking at pixels and needs specific ways to detect things like movement, brightness, or changes in an image. This reminded me of all the games I used to play when I was younger that used cameras to track your movements, like Kinect Adventures on the Xbox. I remember having to stand in a certain area so the camera could see my full body, and then my movements would control what was happening in the game.
Thinking about how those games were able to track us also connected to the different techniques mentioned in the reading. The computer can look for movement between frames, separate someone from the background, or use differences in brightness to figure out what it needs to track. The reading also talks about how things like lighting and contrast can make this easier. This also reminded me that in some games, the camera would not track you properly if you were standing in the wrong place or the room was not set up well.
But that ability to track people also made me think about the other side of computer vision. Tracking can make interactive art really fun because, like those games, your actual body can become part of the experience. At the same time, the surveillance examples in the reading made me realize that the same ability to track someone’s body and movements can also be used to watch them without them really knowing. I think there is a big difference between choosing to be tracked because you are playing a game or interacting with an artwork and being tracked without knowing that it is happening.
