\nFunction: noun<\/em>

1<\/strong> archaic<\/em> :<\/strong> carriage<\/a>, bearing<\/a> Main Entry:\tma\u00b7nip\u00b7u\u00b7late<\/strong> 1<\/strong> :<\/strong> to treat or operate with or as if with the hands or by mechanical means especially in a skillful manner You can already start to see the differences for our purposes. One is emotional, symbolic, indirect. The other is direct or mechanical. There are 4 primary differences<\/strong> between the two and they are easily classified after you know them.<\/p>\n In Dan Saffer’s book, Designing Gestural Interfaces,<\/em> (O’Reilly, 2009)<\/a> on page 2 he states “for the purposes of this book, is any physical movement that a digital system can sense and respond to without the aid of traditional pointing devices such as a mouse or stylus.” That may be a simple way to define the types of interaction for his book, but generalizing them in that manner is incorrect. I think Professor Shneiderman’s<\/a> seminal paper in 1983<\/a> was absolutely correct. Direct manipulation is just that, direct manipulation. When we start to discuss more complex chained movements that are commands, we need a new set of terminology. (http:\/\/en.wikipedia.org\/wiki\/Direct_manipulation_interface<\/a>)<\/p>\n Manipulations are the lowest common denominator and the “catch-all.” They are the most prevalent and the most widely patterned because they are easy to design for, easy to understand, and very intuitive with expected results. Gestures are more complex and is what all designers strive to achieve. When trying to decipher if something is a manipulation or a gesture, unless it passes all 4 tests for gesture, it is a manipulation. There are very few true gestures in systems currently.<\/p>\n These have also been called direct gestures (manipulations) and indirect gestures (gestures). Calling them this is confusing the terms and can lead to errors in design or implementation. I leave you with a graphical representation of gestures vs manipulations.<\/p>\n
