Abstract
We propose a haptic scanner that records vibrotactile and pressure stimulations as audio signals. Most of exiting the haptic sensors sense physical properties of real objects. However, haptic sensation is an integration of a considerable amount of sensory information and therefore, these methods require complex algorithms for converting properties to haptic stimulations. To simplify recreating haptic stimulations, we use recorded vibration sounds as the vibrotactile stimulations. Additionally, we sense contact forces by observing the amplitude modulations caused by change of resistance. Audio signals are preferable for record, edit and share. Especially, our proposed method can use haptic information as general stereo audio signal. Therefore, users can introduce haptic information to a variety of existing media and design new haptic media easily.
