Acknowledgments

We would like to thank the following people for their help: 

Dr. Ben Shneiderman, for guiding our project, making invaluable and useful comments and suggestions, and making this project a well designed and well executed one.. 

Our subjects, for their participation in our study despite the very long experiment time and their useful comments about the advantages and drawbacks of both data entry methods.

Our reviewers Semion Bezrukov, David Bowler, Sarani Mukherji, and Wayne Christopher Williams, for their useful suggestions.
