CPM-GOMS
CPM-GOMS is a variation of the GOMS technique in human computer interaction. CPM-GOMS stands for two things: ''Cognitive Perceptual Motor'' and the project planning technique '' Critical Path Method'' (from which it borrows some elements). Overview CPM-GOMS was developed in 1988 by Bonnie John, a former student of Allen Newell. Unlike the other GOMS variations, CPM-GOMS does not assume that the user's interaction is a serial process, and hence can model multitasking behavior that can be exhibited by experienced users. The technique is also based directly on the model human processor - a simplified model of human responses. Evaluators begin a CPM-GOMS analysis in the same way they would a CMN-GOMS analysis. However, when the tasks are broken down just to the level where they are still perceptual or motor, the evaluator applies techniques from the model human processor. The tasks are first joined together serially and then examined to see which actions can be overlapped so t ...

GOMS
GOMS is a specialized human information processor model for human-computer interaction observation that describes a user's cognitive structure on four components. In the book ''The Psychology of Human Computer Interaction''. written in 1983 by Stuart K. Card, Thomas P. Moran and Allen Newell, the authors introduce: "a set of Goals, a set of Operators, a set of Methods for achieving the goals, and a set of Selections rules for choosing among competing methods for goals." GOMS is a widely used method by usability specialists for computer system designers because it produces quantitative and qualitative predictions of how people will use a proposed system. Overview A GOMS model is composed of methods that are used to achieve specific goals. These methods are then composed of operators at the lowest level. The operators are specific steps that a user performs and are assigned a specific execution time. If a goal can be achieved by more than one method, then selection rules are used to ...

CMN-GOMS
CMN-GOMS stands for Card, Moran and Newell GOMS. CMN-GOMS is the original version of the GOMS technique in human computer interaction. It takes the name after its creators Stuart Card, Thomas P. Moran and Allen Newell who first described GOMS in their 1983 book ''The Psychology of Human Computer Interaction''. Overview This technique requires a strict goal-method-operation-selection rules structure. The structure is rigid enough that the evaluator represents the tasks in a pseudo-code format (no formal syntax is dictated). It also provides a guide for how to formulate selection rules. This method can also be used to estimate the load the task places on the user. For instance, examining the number of levels down the task-tree that a goal branch is can be used to estimate the memory demand the task places on the system. The process must remember information about all of the levels above the current branch. This technique is more flexible than the Keystroke-Level Model (KLM) b ...

NGOMSL
NGOMSL (Natural GOMS Language) is a variation of the GOMS technique in human computer interaction. Overview Natural GOMS Language technique was developed by David Kieras in 1988. The motivation was to make GOMS/CCT ( cognitive complexity theory) simple to use, and still keep the power and flexibility of standard GOMS. This was necessary because GOMS did not have very well defined semantics. This lack of definition meant that two equally competent evaluators could do evaluations on the same system and come up with very different results. Kieras's result was the development of high-level (natural language) syntax for GOMS representation with directions for doing a GOMS evaluation. The recipe is referred to as a "top-down, breadth-first" expansion. The user's high-level goals are unfolded until only operators remain. Generally operators are considered to be keystroke-level operations, but that is not a rigid requirement. Since NGOMSL is based on CCT, it has certain properties that ...

Human Computer Interaction
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically modern huma ...

Bonnie E
Bonnie, is a Scottish given name and is sometimes used as a descriptive reference, as in the Scottish folk song, My Bonnie Lies over the Ocean. It comes from the Scots language word "bonnie" (pretty, attractive), or the French bonne (good). That is in turn derived from the Latin word "bonus" (good). The name can also be used as a pet form of Bonita. People named Bonnie Women * Bonnie Bartlett (born 1929), American actress * Bonnie Bedelia (born 1948), American actress * Bonnie Bernstein (born 1970), American sportscaster * Bonnie Bianco (born 1963), American singer and actress * Bonny Blair (born 1964), retired American speedskater * Bonnie Bramlett (born 1944), American singer and sometime actress * Bonnie Crombie (born 1960), Canadian politician, formerly Member of the Canadian Parliament * Bonnie Curtis (born 1966), American film producer * Bonnie Dasse (born 1959), retired American track and field athlete * Bonnie Dobson (born 1940), Canadian folk music songwriter, singer, ...

Allen Newell
Allen Newell (March 19, 1927 – July 19, 1992) was a researcher in computer science and cognitive psychology at the RAND Corporation and at Carnegie Mellon University’s School of Computer Science, Tepper School of Business, and Department of Psychology. He contributed to the Information Processing Language (1956) and two of the earliest AI programs, the Logic Theory Machine (1956) and the General Problem Solver (1957) (with Herbert A. Simon). He was awarded the ACM's A.M. Turing Award along with Herbert A. Simon in 1975 for their basic contributions to artificial intelligence and the psychology of human cognition. Early studies Newell completed his Bachelor's degree in physics from Stanford in 1949. He was a graduate student at Princeton University from 1949–1950, where he did mathematics. Due to his early exposure to an unknown field known as game theory and the experiences from the study of mathematics, he was convinced that he would prefer a combination of exper ...

Model Human Processor
Human processor model or MHP (Model Human Processor) is a cognitive modeling method developed by Stuart K. Card, Thomas P. Moran, & Allen Newell (1983) used to calculate how long it takes to perform a certain task. Other cognitive modeling methods include parallel design, GOMS, and keystroke-level model (KLM). Cognitive modeling is one way to evaluate the usability of a product. This method uses experimental times to calculate cognitive and motor processing time. The value of the human processor model is that it allows a system designer to predict the performance with respect to time it takes a person to complete a task without performing experiments. Other modeling methods include inspection methods, inquiry methods, prototyping methods, and testing methods. The standard definition for MHP is: The MHP draws an analogy between the processing and storage areas of a computer, with the perceptual, motor, cognitive and memory areas of the computer user. The human processor model ...
