However, in terms of using video, if there are no people in front of webcam, people cannot experience the blurred faces. There is nothing when people look at the screen. In order to overcome the downside regarding the feature of video, I decided to make image-based surveillance, not video-based. It means that when people pass in front of a webcam, the cam recognises and captures faces. After capturing, the captured images are automatically saved, and the stored pictures are loaded on the screen afterwards. It can make people to experience both of aspects in the space. To sum it up, before coming to the screen, they are captured with blurred faces, and then when they get in front of the screen, they realise that they are confidentially captured. However, due to the face protection system for visual anonymity, their identity is not exposed as a point of compromise. And, it is the most effective way to show my theory. This is the first step regarding capturing and saving pictures.
And then, recalling the saved images on the screen in real time is the second step.
