Tactile feedback has been widely used in smartphones in recent years. To explore the factors impacting the user experience of smartphone tactile feedback, the current study tested three aspects of these factors: the intensity of vibration (weak, moderate and strong), feedback times (once or twice) and the interval between two vibrations (100 ms, 230 ms, 370 ms and 500 ms). Twenty-six participants evaluated their tactile experience after finishing each touch task under different conditions on a model phone with three gestures. The results showed that satisfaction with tactile feedback increased along with the increasing intensity of vibration. However, such tactile satisfaction decreased as the interval between two vibrations increased. There was a significant interaction between the intensity and interval of vibrations. The results of the current study can provide guidance for product design in the related field of touchscreen products. © 2019, Springer Nature Switzerland AG.
