Abstract: We proposed a ferro-fluid based tactile display, which is lightweight and portable, but can replicate convincing contact orientation and texture information. Numerous studies have been conducted to develop tactile displays for providing convincing tactile feedback. However, most of the displays were limited in portability and restricted to delivering either texture information with vibrational cues or contact orientation with force feedback. To the best of our knowledge, the proposed tactile display is the first wearable tactile display which can deliver texture information together with contact orientation, and still be lightweight and portable. Introducing ferro-fluid allows minimizing the moving actuator components and also eliminates any counter reactive force on the fingernail of the user which may distort the tactile sensation otherwise. The demo will showcase ferro-fluid based tactile display for curvature discrimination and texture cues.
