Abstract

Touch-based tablet devices are starting to be used frequently in meetings and places of discussion. However, are tablets really ideal as discussion tools? Or do they actually obstruct communication? To answer these questions, this paper quantitatively compares discussion processes involving paper, an iPad2, and a laptop PC. We performed an experiment where 12 groups of two participants each (24 participants in total) worked collaboratively by referring to documents and using paper, an iPad2, or a laptop PC as presentation media. We observed verbal and non-verbal interaction between participants. First, we investigated the total amount of speech between two participants and found they spoke more when using paper than when using the electronic media. Next, we observed that participants used more demonstrative pronouns when using paper than when using the iPad2 but used more demonstrative pronouns when using the iPad2 than when using the laptop PC. Also, they made more eye contact when using paper than when using the other media. These results suggest that tablets may not currently be the best media to use when ideas should be actively exchanged, sensitivity is required toward other participants in the discussion, or work progress needs to be shared.
