| Outline of Final Research Achievements |
Visual attraction of various wood products would play an important role to evaluate positive or negative impacts on psychological and/or physiological conditions of observers. We prepared various lumber samples altered contrast of grain patterns, lumber surfaces with gloss shifting, wooden floor patterns, and full-size wooden walls with relatively simple designs. We calculated image characteristics of the samples using our original methods, and measured psychological and physiological responses of the observers who saw the samples freely. Our image analyses effectively and precisely revealed contrast changes in the surfaces of the samples. The image characteristics well corresponded to the results of sensory evaluations by the observers. We confirmed that the observers' cognitive responses were affected by the contrast variations of surface features and were also affected by the arrangement of wooden elements in the floor and wooden members in the wall.
