This study aims to examine the effects of a touchscreen device (iPad in this study) on students' learning compared to a desktop PC in terms of tactile vision. The participants were 56 undergraduate students: 24 studied using a desktop PC (mouse-based interaction) and the others studied using a touchscreen device (touch-based interaction) about the human heart through interactive images. MANOVA results revealed a significant main effect for the device type. Three follow-up ANOVAs revealed that the students in the touch-based interaction condition significantly outperformed those in the mouse-based condition in terms of the identification test, but there were no statistical differences in terms of factual and conceptual knowledge acquisition. This study reveals that the touchscreen users engage with the screen, which improves their understanding of the objects.
