3D Printed Tactile Illusions and Demonstrations

Appreciating a sensory illusion requires first hand experience with the stimulus. While visual and auditory illusions can be rendered using commonly available hardware, hap-tic illusions often require dedicated mechanical systems. This work introduces a series of haptic illusions and demonstrations that can be fabricated using any FDM 3D printer and assembled by hand. This is a step forward in increasing the accessibility of tactile illusions for educational purposes.
