Studio 10 - Applying Qualitative Usability Methods

Coding Ethnographic Data

"Coding is an important technique in qualitative research such as anthropology, ethnography and other observer and participant-observer methods."

When we are given Ethnograpic data to code are overall main objective to find meaningful 'chunks' of data and condense them down to a size that can be easily interpretated, without the need to filter through extensive amounts of data each time. As we condense the data into smaller pieces we can begin to apply a coding scheme to the discussion i.e.

Agent: "London is a good starting point" GIVE_INFO.LOC

Customer: "Sounds good, but what country is that in?" ASK_Q.LOC

Agent: "Before we get started we'll need to discuss flights" GIVE_INF.FLIGHT

There coding schemes are used to describe what the utterances are doing. So to explain further; if you look are the above example you will note that after the agent has mentioned "London is a good starting point" we are then present with the coding (give_info.loc) which is basically telling us that the agent is giving the customer information about a location. On the next line we can tell by using the coding that the customer is then asking a question (Q) about the location (.loc).

I have taken a brief instance of a discussion from a video about a travel agency and created a transcript of what had been discussed and I have then applied coding to create the following:

Agent: "the only way I could get you to South Africa is that you'd have to go with Singapore Airlines"
Coding: GIVE_INFO.FLIGHT

Customer: "ok that's great"
Coding: ANS_INFO.FLIGHT

Agent: "that would actually go from Perth to Singapore and then across to South Africa"
Coding: GIVE_INFO.LOC

Customer: "I'd be quite happy to do that"
Coding: ANS_INFO.FLIGHT

Agent: "the only thing is a lot of these fares are based on mileage. Now most of them will give you 29,000 miles"
Coding: GIVE_INFO.COST

The graph (displayed above) displays the amount of times that the utterance types; Flight, Loc (Location) and Cost appear during the discussion transcript mentioned earlier. The objective of this graph is to conduct research into finding out what is the most common occuring theme from the earlier transcripts.


As you can see from the graph that 3 out of the 5 utterances related to and concerned Flight which translates to 60% of the selected data. These findings go on to show that when booking a holiday the main discussion takes place around Flights with Locations and Cost coming in at a joint second. So we can see now that one of the main problems, when trying to sell holidays to the general public the most important area they will be concerned with 70% of the time is the Flight and its corresponding information. Of course it is easy to identify what the main problem is but moving on to finding a solution provides an entirely different problem in itself; so the holiday sales person will need to link in all other information (location, cost etc) under the umbrella of Flights and its information to provide the customer with enough data that will promote the holiday to them and thus making a sale.


In conlusion; the above discussion was the form of a quantitative analysis on qualitative data and what we have discussed here is the ability of integrating both, qualitative and quantitative data together which provided us with results showing what one of the problems is concerning selling holidays.




Studio 6 - Identifying Research Activities and Methods

Source: http://www.cogentcomputing.org/~john_h/DIS06.pdf

Research activity 1:

This area had curators being asked what sort of information they would divulge to the visitors whilst they were giving a tour. Given a large map which incorporated models of buildings that the curators shared they were asked to discuss the information that they knew about specific parts of the house and explain.

I believe this research activity is used as Qualitative data because the information requested was required in order to find out what type of information the curators give out whilst conducting a guided tour and the information was taken by an un-structured discussion. This type of information will be helpful towards the research because the discussion can be recorded via audio or video and be used and re-used for the content of the system.

Research activity 2:

Researchers were taken on a guided tour whilst a second researcher followed the tour using a camcorder to record the tour.

I believe that this type of research activity comes under both Quantitative and Qualitative data as a mix; mainly because, it allowed the researchers to gain an idea of what specific content were mentioned frequently and what content was only briefly mentioned throughout.

This type of research activity can also be used to help backup the previous research activity (above) as it was recorded as well. Also this research activity can be used as content for the system.

Research activity 3:

This next research activity involved the researchers taking the curators a video of Ambient Wood before taking them on a walk around the house using audio clips to be played back to the curators, so that they could understand what it would be like to be a visitor to the house and how the tour would also sound to the visitor.

This research activity is a Quantitative data research because the curators were asked to take a vote on:

  • Their voices being used in the system
  • Like/Dislike the organisation of the transcripts

This therefore means that there will be a number of people for each case to be presentated using the researchers statistical results. The research activity also allows the researchers to make a more informed decision on how to improve and further develop the current system.

Research activity 4

School children were used in this research activity, where they were sent around the Chawton House with a mobile device that allowed the school children to complete the scenario given to them by the researchers.

The school children were told to complete a number of different tasks that required them to use the mobile device and also to interact with the Chawton House as well. The research method used within this research activity is a mixture of Quantitative and Qualitative data methods.

Throughout the Chawton House Project the school children gave feedback to the researchers about what they thought of the system (this feedback would then be used to develop potential stories). Also throughout the project the researchers watched the school children and how they interacted with the system/house and then they were interviewed at the fourth phase of the Chawton House Project workshop. As like all of the previous research activities this one also helped to further develop and improve the system.
