In our previous research, we introduced a technique for creating a natural tracing sensation. This was achieved by touching a rotating a small disk, the size of a fingertip. This approach is advantageous due to its compact design and the use of the physical sliding of objects. However, its limitation lies in its inability to represent multiple textures, limited to the surface material of the rotating disk. In contrast, numerous studies have explored varying textures through vibration. Consequently, we explored the potential of simulating diverse textures by merging this vibrational texture representation with the tracing sensation produced by the rotation of the disk. Based on this concept, we developed a system that provides stimulation through both disk rotation and vibration. Our system utilizes the same actuator for both rotating and vibrating the disk. We carried out an experiment to assess how realistic the generated stimulus feels, comparing it to the sensation of tracing an actual 1D grating plate. The findings indicated that we can realistically replicate multiple textures with varying degrees of roughness. Furthermore, our results showed that in many instances, the difference between the bump spacing and the vibration frequency had minimal impact on the perceived realism.

摘要

In our previous research, we introduced a technique for creating a natural tracing sensation. This was achieved by touching a rotating a small disk, the size of a fingertip. This approach is advantageous due to its compact design and the use of the physical sliding of objects. However, its limitation lies in its inability to represent multiple textures, limited to the surface material of the rotating disk. In contrast, numerous studies have explored varying textures through vibration. Consequently, we explored the potential of simulating diverse textures by merging this vibrational texture representation with the tracing sensation produced by the rotation of the disk. Based on this concept, we developed a system that provides stimulation through both disk rotation and vibration. Our system utilizes the same actuator for both rotating and vibrating the disk. We carried out an experiment to assess how realistic the generated stimulus feels, comparing it to the sensation of tracing an actual 1D grating plate. The findings indicated that we can realistically replicate multiple textures with varying degrees of roughness. Furthermore, our results showed that in many instances, the difference between the bump spacing and the vibration frequency had minimal impact on the perceived realism.
