For me, first of all, I will abide by The Law of Proximity and The Law o Similarity, pay more attention to the classification of elements, and differentiate them by size, color and distance. In addition, for the logo design, I will think about whether it is possible to have more ingenuity in negative space by leaving out the gap, because The Law of Closure makes me understand that the human eye will think that such a logo is still closed. Also I will refer to the layout of past competitors because The Law if Past Experience tells me that people will think in terms of past experience. In addition, Fitts’s law also made me realize that the size of the elements is also very important to pay attention to, because it is necessary to distinguish the relationship between primary and secondary, so that the logic of the app can be clear and correct.
