A Study on the C/R Ratio of Direct-Operation Multi-touch Interface
Multi-touch interface is becoming an important part of consumer information products. Interface design should have more in-depth understanding to achieve better human-computer interaction. This study investigates the multi-touch interface’s control/response ratio (C/R ratio) with rotation and moving tasks to understand the effects on participant’s performance and satisfaction. The results showed that the better C/R ratio is not the same for efficiency of different operating tasks. And the user satisfaction was affected by previous experience of the participants.
