•Cultural differences in category formation-The proposition

•Research Methodology-Material-Experiment of card sorting- Probe sort-Tool for analysis

•Analysis techniques-Edit distance-probesort-Neighborhood

•Result of Experimental Session- Edit distance of Universal card sort 1, 2, 3-Edit distance from prespective probe sorts-Comparison of Universal sort and local sort

•Summary•Practical importance

Research Goal

‘‘To investigate people’s information structure in Denmark and China and measure the difference in the information structure of categories in Chinese and Danish cultural groups’’

DDM

Cultural differences in category formation

•Western cultures group objects together based on shared object attributes.

•Eastern Culteres group objects together based on shared relationships

DDM

The proposition

Categories form the basis of information architectures in software applications

• Organization of menus in WindowsTM interfaces,

• Links in websites,

• File directories,

Analysis Techniques

Edit distanceBased on Distance function or distance metric ( Rudin, 1976), calculate

the distance between two set of points.

‘‘Minimum number of operations need to convert one card into another card ’’(Deibel et al, 2005)

Analysis Techniques

Sort A Sort B

A1 = {1, 2, 3, 4} B1 = {1, 2, 3 }

A2 = {5, 6,7} B2 = {4, 5, 6}

A3 = {8, 9, 10} B3 = {7, 8, 9}

A4 = { } B4 = { 10 }

Application of Edit Distance

Neighborhoods’’The d-neighborhood of sort S is defined to be set of all sorts with

distance of at most d of S’’

(Deibel et al, 2005)

Probes’’A probe sort is a sort s pecifically constructed by the researcher to

represent a sort criterion of interest’’

(Deibel et al, 2005)

Summary

• More Variability in Chinese subjects as compare to Danish subjects

• Greater use of "other“ category in Chinese users

• More chinese used holistic categories as compare to danish users.

• Chinese subjects take holistic view of category and puts more object in one category.

• Method of usability testing, which involve less number of subjects, can be used to test usability of information.

• Foreground color of data and information is important for Danish subjects.

• Usability of colors in information structure largely depends on target audience preference because Chinese subjects identified red color more than Danish subjects

DDM

Practical Importance of this study and similar work

• For designers

Going to design for two countries

• Usability testers Testing internationally in different countries
