title = "Modified control-response ratio for move and rotation operations on a large multi-touch interface",
abstract = "This study focused on the effect of the control-response ratio (C/R ratio) of a multi-touch interface for move and rotation operations. The experiments were conducted to collect data on user performance and subjective evaluation to analyze the effects of five levels of the C/R ratio. Forty-five participants, 15 male and 30 female, were given tasks to complete. The results showed that in overall operations, subjective satisfaction was highest with the C/R ratio 1/1, but in the usability analysis among the C/R ratios 1/1, 1/2, and 2/1, there was no significant difference. Specific operations that analyzed the effects of the C/R ratio showed in the move operations the best C/R ratio was located between 1/1 and 1/2, and in the rotation operations, the difference among the C/R ratios 2/1, 1/1, and 1/2 was not significant. The best C/R ratio might be located among the three values. The results show that on a mid-size multi-touch screen, a modified C/R ratio may help users in pan and rotation operations to improve performance and satisfaction.",
