In mind-computer communication, when we push with our mind in order to move a cube on the screen, we are creating a mental interface. The mental interface acts as the hand - it is a human interface that talks to a computer interface (an EEG headset for instance). While the hand exists in the physical space, the mental interface exists in the mental space.
Mental space
Every time we need to perform an action with our mind, our brain creates an interface in our mental space to be able to perform that action. It is a temporary interface that exists for the period of time we need to perform the action for.
Like the hands, the mental space belongs to each individual, and it cannot be created by anyone else than its owner.
Elements in a graphical user interface are normally arranged in a grid. Grids help to organise those elements, set them up in hierarchy and present them in an aesthetic manner. It also helps the users to create mental models of the interactions, and it helps the designers to adopt certain conventions on interface design.
Metaphors
Metaphors in human-computer interfaces make use of previous knowledge or mental models the user has to facilitate the understanding and use of those interfaces. Many of the metaphors used in GUI are references to the physical world. Some of these metaphors have evolved or disappeared in favour of interfaces based completely on flat, digital references. There are also gestural metaphors based on natural gestures, such as swipe with a finger to browse pictures in a screen - as you would do with photographs over a table
