Emergent smartphone users' dataset

Data is cleaned. All inconsistencies and erroneous records have been removed. These two datasets are used to see how the composition of the contact-book of emergent users differ from those of traditional users in aspects like its size, prevalence use of special symbols, the proportion of dialed contacts through the phone-book, and percentage of unintelligible contact names, etc. Aggregated data for 30 emergent users and 30 traditional users is provided in the form of CSV files to replicate the data analysis results. To reproduce the graphs for usability analysis, R scripts are also provided in the same repository. These scripts contain the required data vectors. These graphs show the efficiency, effectiveness, and satisfaction of emergent users on conventional contact-book interfaces.
