Generating Haptic Sensations over Spherical Surface

Abstract

<p>Haptic imagery, the imagining of haptic sensations in the mind, makes use of and extends human vision. Thus, enabling a better understanding of multi-dimensional sensorimotor information by strengthening space exploration with “seeing by touch." Testing this concept was performed on a spherical surface to optimize the way of generating localized haptic signals and their propagation across the curved surface to generate dynamic movements of perceivable peak vibrations. Through testing of several spherical structure prototypes, it was found that offset actuations can dynamically amplify vibrations at specific locations. A pilot study was followed to understand the impact of haptic stimulation on viewers of video content in a passive VR environment. Results showed a correlation between heart rate and the presented content; complimenting the technical data recorded.</p>
