Main article: Mechanics Mechanics is, in the most general sense, the study of forces and their effect upon matter. Typically, engineering mechanics is used to analyze and predict the acceleration and deformation both elastic and plastic of objects under known forces also called loads or stresses. Subdisciplines of mechanics include Statics , the study of non-moving bodies under known loads, how forces affect static bodies Dynamics the study of how forces affect moving bodies. Dynamics includes kinematics about movement, velocity, and acceleration and kinetics about forces and resulting accelerations. Mechanics of materials , the study of how different materials deform under various types of stress Fluid mechanics , the study of how fluids react to forces  Kinematics , the study of the motion of bodies objects and systems groups of objects , while ignoring the forces that cause the motion.
Can be used at any point in the design process, as it is largely dependent on the exact questions to be pursued, and the structure of the group. Can be extremely costly.
Iterative design: Also known as prototyping, the iterative design process seeks to involve users at several stages of design, in order to correct problems as they emerge.
As prototypes emerge from the design process, these are subjected to other forms of analysis as outlined in this article, and the results are then taken and incorporated into the new design.
Trends amongst users are analyzed, and products redesigned. This can become a costly process, and needs to be done as soon as possible in the design process before designs become too concrete. Meta-analysis: A supplementary technique used to examine a wide body of already existing data or literature in order to derive trends or form hypotheses in order to aid design decisions. As part of a literature survey, a meta-analysis can be performed in order to discern a collective trend from individual variables.
Subjects-in-tandem: Two subjects are asked to work concurrently on a series of tasks while vocalizing their analytical observations.
The technique is also known as "Co-Discovery" as participants tend to feed off of each other's comments to generate a richer set of observations than is often possible with the participants separately.
This is observed by the researcher, and can be used to discover usability difficulties. This process is usually recorded. Surveys and Questionnaires: A commonly used technique outside of Human Factors as well, surveys and questionnaires have an advantage in that they can be administered to a large group of people for relatively low cost, enabling the researcher to gain a large amount of data.
Those who actually respond are in effect self-selecting as well, widening the gap between the sample and the population further. Task analysis: A process with roots in activity theory, task analysis is a way of systematically describing human interaction with a system or process to understand how to match the demands of the system or process to human capabilities.
The complexity of this process is generally proportional to the complexity of the task being analyzed, and so can vary in cost and time involvement. It is a qualitative and observational process.
Best used early in the design process. Think aloud protocol: Also known as "concurrent verbal protocol", this is the process of asking a user to execute a series of tasks or use technology, while continuously verbalizing their thoughts so that a researcher can gain insights as to the users' analytical process.
Can be useful for finding design flaws that do not affect task performance, but may have a negative cognitive affect on the user. Also useful for utilizing experts in order to better understand procedural knowledge of the task in question. Less expensive than focus groups, but tends to be more specific and subjective.
User analysis: This process is based around designing for the attributes of the intended user or operator, establishing the characteristics that define them, creating a persona for the user. Best done at the outset of the design process, a user analysis will attempt to predict the most common users, and the characteristics that they would be assumed to have in common. This can be problematic if the design concept does not match the actual user, or if the identified are too vague to make clear design decisions from.
This process is, however, usually quite inexpensive, and commonly used. Based upon the Wizard of Oz experiment, this technique involves an operator who remotely controls the operation of a device in order to imitate the response of an actual computer program.
It has the advantage of producing a highly changeable set of reactions, but can be quite costly and difficult to undertake. Methods Analysis is the process of studying the tasks a worker completes using a step-by-step investigation. Each task in broken down into smaller steps until each motion the worker performs is described. Doing so enables you to see exactly where repetitive or straining tasks occur. Time studies determine the time required for a worker to complete each task. Time studies are often used to analyze cyclical jobs.
They are considered "event based" studies because time measurements are triggered by the occurrence of predetermined events. Work sampling is a method in which the job is sampled at random intervals to determine the proportion of total time spent on a particular task. It provides insight into how often workers are performing tasks which might cause strain on their bodies.
Predetermined time systems are methods for analyzing the time spent by workers on a particular task. Read as much as you can. This can be fiction, non-fiction, newspaper articles; in short anything that interests you.
While reading , you would surely encounter new words. I would suggest maintaining a diary of the word meanings: very useful. Trust me!
This can be in the form of Radio programmes, T. While you listen, you sub-consciously pick the language up, an added bonus to simple entertainment.
A mirror comes to your rescue. Stand in front of a mirror, choose any topic of your choice and speak anything you feel like , for a few minutes. This would boost your conversation skills tremendously and your confidence too, undoubtedly… Remember… While you speak, you are the only speaker and the sole listener.
