Gestalt Laws and Design

What is Gestalt?
When human beings look at a painting or a web page or any complex combination of elements, we see the whole before we see the individual parts that make up that whole. This idea of seeing the whole before the parts and even more the whole becoming more than the sum of its parts is Gestalt.

The German word gestalt can be translated as “shape” or “form” and the term refers to how visual input is perceived by human beings. Gestalt psychology was founded by Max Wertheimer and has been added to over the years by other authors.

Wertheimer’s original observation was that we perceive motion when there is nothing more than a rapid sequence of individual sensory events such as a series of lights flashing in sequence. Imagine a string of Christmas lights. Each light turns on and off in sequence along the string. We see the movement of light from one end of the string to the other, when in reality nothing has moved.

We see something that’s not really there and Wertheimer’s explanation is that we see the effect of the whole event that is not necessarily contained in the sum of the parts.

Science Fiction's Robotics Laws Need Reality Check

Artificial intelligence researchers often idealize Isaac Asimov's Three Laws of Robotics as the signpost for robot-human interaction. But some robotics experts say that the concept could use a practical makeover to recognize the current limitations of robots.

Self-aware robots that inhabit Asimov's stories and others such as "2001: A Space Odyssey" and "Battlestar Galactica" remain in the distant future. Today's robots still lack any sort of real autonomy to make their own decisions or adapt intelligently to new environments.

But danger can arise when humans push robots beyond their current limits of decision-making, experts warn. That can lead to mistakes and even tragedies involving robots on factory floors and in military operations, when humans forget that all legal and ethical responsibility still rests on the shoulders of homo sapiens.

"The fascination with robots has led some people to try retreating from responsibility for difficult decisions, with potentially bad consequences," said David Woods, a systems engineer at Ohio State University.

Woods and a fellow researcher proposed revising the Three Laws to emphasize human responsibility over robots. They also suggested that Earth-bound robot handlers could take a hint from NASA when it comes to robot-human interaction.
