| Outline of Final Research Achievements |
In this study, the design requirements of the haptics interface using the pulling illusion were clarified to achieve novel displays for mobile and wearable devices. When strong and weak stimuli are applied sequentially, the user perceives the former; however, they do not clearly perceive the latter. Therefore, the pulling illusion is induced using vibrations with asymmetric acceleration. However, the effect of the illusion has not been evaluated for scenarios where the acceleration profiles of asymmetric vibrations are marginally changed. Therefore, a vibrator that can provide flexible control for the asymmetric vibrations was developed. Using this vibrator, the characteristics of the illusion were clarified by ergonomics experiments. In addition to the findings obtained through ergonomics experiments, an academic survey determined the design requirements for the haptic interface. Finally, based on the obtained design requirements, modules to experience the illusion were developed.
