Outline of Final Research Achievements

The information about an object is built by different sensory modalities that converge somewhere in the human brain to form representations that are invariant to the input modality. To develop a high quality surface machining system, the following researches were implemented: 1) Investigation of interactions between haptic and visual perceptions of fine surface texture. 2) Development of MRI-compatible tactile and visual stimuli presentation system. 3) Investigation of brain activations related to cross-modal interactions of haptic-visual texture matching. 4) Discussion of functional asymmetry processing of haptic-visual roughness information transformation. 5) Development of a database including material and surface qualities physical parameter and brain activation patterns.
