hint as a slight or indirect indication or suggestion always used by people to communicate with. it is not possible to isolate human behaviour and environment. hint can exist in both human behaviour and the space itself.
in order to find the relationship between human and space, i observed people in different kinds of space and analysis their personality and reflection to the space.i also found that the sapce between people have function that can suggest the atmosphere and their relationship. human behaviour not only related to the space, In most cases it is related to the substances in the space, the substances which means hint could lead them to do the hinting things, that is what i called "hint".
