# Different "users"

* Server: this is the server where our node server process runs. We serve our website from here. This is also where we keep track of registered “clients”. Our server keeps websocket connections with the clients. There is only one server.
* Client: is either a “screen” or a “controller”.
* Screen: this is a web browser which makes available its view port to be used for showing the game. Note that one computer could have multiple browser windows and hence multiple “screens”, which might be on the same physical display or on different displays. Multiple computers can register multiple “screens” at the same time. We assume that different “screens” do not overlap.
* Controller: this is a smartphone which is used to control a cat in the game. We make use of the gyroscope to move in a certain direction and we make use of the accelerometer to jump through a wormhole.
