  Layered Interaction Analysis of Direct Manipulation
The idea of direct mappings is similar to the mathematical notion of isomorphisms; there is a one-to-one function between the two levels and the relationships between the units of information are the same on the two levels and are preserved by the function.
Direct manipulation may be defined as a direct mapping between the semantic level of the dialogue and the syntactic level.
Analyzing the concept of direct manipulation according to a detailed layered interaction model indicates several modifications to a simplistic view-especially with respect to error situations where usability often is better served by explicit error handling.

 Direct Manipulation
Direct manipulation is a style of Human Machine Interaction (HMI) design which features a natural representation of task objects and actions promoting the notion of people performing a task themselves (directly) not through an intermediary like a computer.
Direct manipulation is a topic in the interdisciplinary field of HCI.
Direct manipulation harnesses these strengths resulting in systems whose operation is easy to learn and use and difficult to forget.

 The Direct Manipulation of Pasted Surfaces
My goal is to provide a multiresolution direct manipulation technique that allows the user to pick a point on a surface and move it to a new location and have the shape of the surface change appropriately.
My method for the direct manipulation of pasted surfaces is a variation of a technique developed by Bartels and Beatty for the direct manipulation of spline curves.
I chose to disallow direct manipulation of a pasted surface when the most influential block of control points intersects the two outermost rings of the surface's control points.

 Designing Applications for the Power Macintosh
By emphasizing direct manipulation, we reduced even algebraic simplification, a task that might seem to require a command-line interface, to the paradigm of MacDraw.
We were pleased to discover that with direct manipulation, we could simplify the interface without giving up powerful functionality.
Since direct manipulation doesn't require users to learn any new commands or concepts, the manipulations immediately become part of a user's arsenal of tools.

 Graphical user interface - Facts, Information, and Encyclopedia Reference article
A graphical user interface (or GUI, sometimes pronounced "gooey") is a method of interacting with a computer through a metaphor of direct manipulation of graphical images and widgets in addition to text.
The precursor to GUIs was invented by researchers at the Stanford Research Institute (led by Doug Engelbart) with the development and use of text-based hyperlinks manipulated with a mouse for the On-Line System.
The "direct manipulation interface" term is usually not presented as an acronym.

 2.1 - Introduction to DesignWorkshop
The power and flexibility of DesignWorkshop are based on the direct manipulation of 3D objects in three-dimensional space.
This is possible because the total interface including noun-verb selection syntax, direct graphic manipulation of objects, and a minimalist iconic command set allows the designer to produce graphic results with a small set of fairly general functions.
To allow 3D direct manipulation, interaction is based on a three-dimensional crosshair, easily controlled by the standard mouse.

 Graphical user interface - Wikipedia, the free encyclopedia
A graphical user interface (or GUI, often pronounced "gooey") is a method of interacting with a computer through direct manipulation of graphical images and widgets in addition to text.
They developed use of text-based hyperlinks manipulated with a mouse for the On-Line System.
The concept of hyperlinks was further refined and extended to graphics by researchers at Xerox PARC, who went beyond text-based hyperlinks and used GUIs as the primary interface for the Xerox Alto computer.
