Users impressions about visualization techniques in social networks context

Abstract

This paper introduces a study to analyse the users impressions about different visualization techniques. To achieve this, we used the Spot tool, which provides a set of different visualization techniques to users with information retrieved from Twitter. This study was conducted with a sample of 7 Twitter users who have never used this tool before. We collected their impressions and interactions with the system on each visualization technique available. When running a qualitative analysis of the data gathered, an interesting set of results were found. Advantages and disadvantages for each visualization technique introduced were found by all users. This led us to a discussion on where each kind of those techniques would be better introduced or used.
