Naturalistic Observation

Primary Reference Resource

Loucopoulos L and V Karakostas (1995) System Requirements Engineering. McGraw Hill Foreign.

Summary description

Observational strategies involve an investigator observing users because they work and taking notes on the activity which will takes place. Observation may be possibly direct, where the investigator is in fact present through the task, or perhaps indirect, the place that the task can be viewed by simply some other means such as through use of a video camera.

Standard Application Areas

Useful early in specs for obtaining qualitative info.

This approach is an alternative (non-involving) edition of Contextual Inquiry. It is useful for studying currently carried out tasks and processes. It has been extensively advocated in the past.

Rewards

Allows the observer to view what users actually do in context. Immediate observation permits the detective to focus attention on certain areas of fascination. Indirect remark captures activity that would or else have gone unrecorded or unnoticed.

Limitations

Noticing can be obtrusive and topics may change their behavior due to the occurrence of an observer. Co operation of users is vital and so the interpersonal skills of the viewer are important. Records and online video tape should be analyzed by note-taker which can be time consuming and prevents the work being separation for analysis by a number of individuals. If incidents or behaviors which happen at capricious intervals are of interest, this sort of observation could become extremely time-consuming.

Cost of work with

Analysis normally takes 5 to 7 occasions the amount of period spent documenting events unless a substantial amount of evaluation is done in real-time, during off-peak occasions. Indirect declaration requires access to audio visual recording and playback tools.

Costs of Acquisition

Observers require training and practice in order to take accurate and complete notes. Suitability for requirements engineering in Telematics:

Some spouse experience (SINTEF, NPL, HFRG, NOMOS). Technique widely used in industry by HCI consultants, and lightweight video products are well-known.

How to get this Widely written about in the literature.

Detailed information of technique

Naturalistic Statement as a field method requires the following steps:

1 . Set up objectives and information requirements.

If the coverage take breadth or in depth? It is extremely important at this point to find out what to you suppose will happen to the end-product of this procedure, and therefore to tailor the complete process towards the requirements of these who will get the results.

2 . Gain contacts and especially all their co-operation with all the process of Naturalistic Observation that you intend to accomplish establish the days, places, and people who will be discovered. Note that in some countries, legislation may forbid you from taking online video films of individuals without all their explicit written consent.

several. Decide on it technique you will use.

Will you rely on hand-written paperwork (traditional), sound, or video and music records? Note that the more full your record, the for a longer time it takes to investigate. It is helpful to be able to produce some kind of first-cut analysis during observation

four. Analyse, sum it up, and survey in relation to the objectives set out at the start.

Observation since an approach within a laboratory environment is instantiated quite specifically using the Laboratory Based Observation approach. A variation of single user statement is two-user observation in which pairs of users will be invited to work together and the above method is performed on the set. One of the users in two-user observation might be a member with the design group, and this is particularly useful in circumstances where there may be an unstable model.

Summary description

This is a technique for studying consumer behaviour in the laboratory, and could be used at practically virtually any stage inside the development procedure when there exists a representation in the software that users may interact with. The book by Rubin is cited on account of its clearness of annotation, but this approach is written about in many sources. J Nielsen advocates an approach he phone calls discount simplicity engineering.

Typical App Areas

These kinds of approaches may be used at any level in the process, though discount usability engineering takes on the existence of a prototype that could stand by itself.

Rewards

The method is visible as a great.

Naturalistic Declaration

Primary Reference Source

Summary description

Observational strategies involve an investigator observing users as they work and taking notes around the activity which takes place. Declaration may be both direct, where investigator is really present throughout the task, or indirect, where the task is usually viewed simply by some other means such as through use of a video camera.

Standard Application Areas

Useful early on in specs for obtaining qualitative data.

This process is another solution (non-involving) version of Contextual Inquiry. It is useful for studying currently performed tasks and processes. It has been extensively strongly suggested in the past.

Benefits

Allows the observer to see what users actually do in context. Immediate observation enables the examiner to focus interest on certain areas of curiosity. Indirect declaration captures activity that would in any other case have gone unrecorded or undetected.

Limitations

Watching can be obtrusive and themes may alter their behavior due to the presence of an observer. Co operation of users is vital therefore, the interpersonal expertise of the viewer are important. Notes and online video tape need to be analyzed by note-taker which can be time consuming and prevents the job being decide to part for analysis by a number of individuals. If incidents or behaviors which happen at unforeseen intervals are of interest, these kinds of observation could become extremely time consuming.

Cost of make use of

Analysis normally takes 5 to 7 instances the amount of period spent saving events unless a substantial amount of examination is done in real-time, during off-peak moments. Indirect statement requires usage of audio image recording and playback products.

Costs of Acquisition

Experts require training and practice in order to consider accurate and notes. Suitability for requirements engineering in Telematics:

Some partner experience (SINTEF, NPL, HFRG, NOMOS). Approach widely used in industry simply by HCI consultants, and portable video kits are well-liked.

How to get that Widely recorded in the materials.

Detailed information of approach

Naturalistic Statement as a field method involves the following actions:

1 . Create objectives and information requirements.

If the coverage maintain breadth or in depth? It is very important at this time to find out what to you suppose will happen to the end-product of this procedure, and therefore to tailor the entire process towards the requirements of those who will obtain the results.

installment payments on your Gain associates and especially all their co-operation while using process of Naturalistic Observation that you intend to execute establish the times, places, and people who will be observed. Note that in some countries, the law may prohibit you from taking video films of folks without their particular explicit created consent.

3. Decide on the recording technique you are going to use.

Will you depend on hand-written remarks (traditional), sound, or video and audio tracks records? Remember that the more finish your record, the longer it takes to assess. It is helpful to be able to produce some kind of first-cut analysis during observation

some. Analyse, sum up, and survey in relation to the objectives placed at the start.

Observation while an approach within a laboratory environment is instantiated quite specifically using the Clinical Based Statement approach. A variation of sole user declaration is two-user observation wherever pairs of users are invited to work together plus the above process is completed on the pair. One of the users in two-user observation could possibly be a member in the design staff, and this is particularly useful in conditions where there might be an unstable modele.

Summary explanation

Observational methods involve a great investigator looking at users as they work and taking notes within the activity which takes place. Declaration may be both direct, the place that the investigator is in fact present throughout the task, or indirect, the place that the task is definitely viewed by simply some other means such as through use of a video camera.

Standard Application Areas

Useful early in specs for obtaining qualitative data.

This method is an alternative (non-involving) edition of Contextual Inquiry. It is useful for studying currently executed tasks and processes. It is often extensively strongly suggested in the past.

Rewards

Allows the observer to look at what users actually do in context. Direct observation permits the investigator to focus interest on particular areas of fascination. Indirect declaration captures activity that would normally have gone unrecorded or undetected.

Limitations

Noticing can be obtrusive and themes may adjust their behavior due to the presence of an observer. Co procedure of users is vital so the interpersonal expertise of the observer are important. Remarks and video tape should be analyzed by the note-taker that can be time consuming and prevents the job being seperated for research by a number of individuals. If occasions or behaviors which take place at capricious intervals are of interest, this sort of observation may become extremely labor intensive.

Cost of make use of

Analysis typically takes 5 to 7 instances the amount of time spent documenting events except if a substantial amount of research is done in real-time, during off-peak moments. Indirect remark requires use of audio aesthetic recording and playback equipment.

Costs of Acquisition

Observers require schooling and practice in order to consider accurate and notes. Appropriateness for requirements engineering in Telematics:

Some spouse experience (SINTEF, NPL, HFRG, NOMOS). Technique widely used in industry simply by HCI consultants, and lightweight video sets are popular.

How to get it Widely documented in the literary works.

Detailed information of technique

Naturalistic Statement as a field method entails the following measures:

1 . Create objectives and information requirements.

Should the coverage have breadth or in depth? It is rather important at this point to find out what to you suppose will happen to the end-product of this method, and therefore to tailor the whole process for the requirements of people who will obtain the results.

2 . Gain associates and especially their particular co-operation together with the process of Naturalistic Observation that you just intend to accomplish establish the times, places, and those who will be observed. Note that in some countries, the law may forbid you by taking online video films of men and women without all their explicit written consent.

3. Decide on it technique you are going to use.

Will you rely on hand-written remarks (traditional), audio tracks, or video and audio records? Remember that the more total your record, the for a longer time it takes to assess. It is helpful to be able to make some kind of first-cut analysis during observation

some. Analyse, sum up, and statement in relation to the objectives placed at the start.

Observation as an approach within a laboratory setting is instantiated quite particularly using the Lab Based Declaration approach. A variation of sole user statement is two-user observation where pairs of users will be invited to work together as well as the above procedure is accomplished on the set. One of the users in two-user observation might be a member from the design crew, and this is very useful in situations where there could possibly be an unstable model.
