Gestalt Principles of Perception things are “more than the sum of their parts:”

Figure and Ground – merging together as one; illusion.

Similarity, Proximity or Contiguity, Continuity, Closure, Area, Symmetry – all basic and important principles for artistic design, how the human eye creates images; in websites we want the eye to like what it sees!

Human-Computer Interface Design
Computer interface design has certain expectations such as the mouse cursor or scroll bar. Without those recognizable conventions, a website appears to be out of place, confirming Gestalt Theory where design is heavily connected to perception. He “eight golden rules of interface design” emphasize features that allow the user to feel familiar and at ease explaining that creativity is only great if it still offers simplicity and clarity in design. The Gestalt Theory is helpful for the visual aspects affording basic principles to follow in order to create something aesthetically pleasing to the eye. A website should satisfy the audience artistically and practically.

Perception and Prevention
One should be able to navigate effortlessly and accomplish their objective when visiting a site. Keeping things simple is sometimes the best option, especially to avoid functionality frustration. Having a similar menu on each page or opening in a new window allows one to avoid going back in search of the original page. The goal is not to get “lost” in a site but rather feel like you are able to do and find everything you desired from the site; perceived affordances.

Question: What sites maximize these design principles and satisfy you as the audience?
