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 d ...

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 ...

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 KLM (human computer interaction ...

Human Information Processor Model
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard Gong
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", " Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish.

Ergonomics
Human factors and ergonomics (commonly referred to as human factors) is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Four primary goals of human factors learning are to reduce human error, increase productivity, and enhance safety, system availability, and comfort with a specific focus on the interaction between the human and the engineered system. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to the four primary goals above. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its cognitive abilit ...

Verizon New England
Verizon New England, Inc. is a Bell Operating Company that serves most of Massachusetts and all of Rhode Island. It was formerly New England Telephone and Telegraph Company, more commonly known as New England Telephone, which for seven decades served most of the New England area of the United States as a part of the original AT&T. New England Telephone's coverage area included Maine, New Hampshire, and Vermont as well as Massachusetts and Rhode Island, but Verizon sold off service in the northern three states, which as of 2020 are served by Consolidated Communications. After the Bell System divestiture, New England Telephone merged with New York Telephone to form NYNEX in 1984. NYNEX was acquired by Bell Atlantic in 1997. In 2000, Bell Atlantic bought GTE and changed its own name to Verizon. New England Telephone was then renamed Verizon New England. History New England Telephone & Telegraph Company (N.E.T.&T.
