The Importance Of A GOMS Analysis

Task 1
1.1) GOMS is currently a famous and longer lasting of a big number of cognitive task investigation methods. It specializes on the cognitive processes required to achieve a particular goal by using a particular device. It comprises of goals, operators, methods and selection rules. A GOMS analysis also shares with HTA the must to describe, organise, and give a structure of tasks, subtasks and actions in a hierarchical way.

Firstly, the goals of the enterprise are of course to make a profit. The introduction of a point of sale system is to make life easier for the employers, the system they are using makes use of creating

Therefore we need to use a metaphor to describe the new domain in terms of something that is familiar to us. Then, after a while, the metaphorical use of a certain term becomes ingrained in the language to such a vast extent that people would generally forget it was a metaphor. Paths and maps are thought of as metaphors contributing to the design of interactions. Therefore, different metaphors will lead to different designs. But the metaphors are not meant to suggest that an interface to a certain product looks the same like the metaphorical item, the main idea is to think about activities in a variety of different ways. • Reimer, Jeremy (5 May 2005).

A desert can be intimidating or beautiful but has fewer landmarks. The night sky has a different sort of space. To the human eye, it looks like clusters and patterns that are big. The open sea encourages a division between depth and surface.

2.2)
A design language consists of the following:
• A set of designing elements such as the use of style and colour and different types of buttons and other widgets.
• Principles of composition. (laws of putting them together)
• A collection of qualifying situations – different contexts and how they affect the laws.
A design language means that people need to learn a limited amount of designing elements and for them to cope with a big variety of situations. A design language is literally how designers build sense into objects, enabling people to understand what things to do and make distinctions between the different types of objects.
Designing interactions
This is critical to the design of interactive systems. The conceptual design must be independent of a functioning as possible. The move from the conceptual to a physical design needs designers to assign functions and knowledge to people or devices and create
