Information about the product value acquired through the five senses is important and if a new factor can be added to a product; it would lead to the differentiation of such a product from other similar products; as well as would improve the value of such a product. This research was aimed at investigating how the evaluation of objects is impacted by the hardness of an object as determined by the tactile sense. This investigation was carried out using silicone rubber and involved examining how the findings can be applied to the differentiation of product values. The investigation indicated that the results of sensitivity evaluation of a product depend on the hardness of silicone rubber and that the hardness values can be distinguished if they vary by at least five degrees. However; it was also found that once the hardness exceeds 60 degrees; it becomes harder to distinguish between the hardness values. Furthermore; when experiments on the application of silicone rubber to push switches were performed; sensitivity evaluation for the products was simultaneously performed; and the evaluation results indicated that the distinction between hardness values became more sensitive by the use of silicone rubber.
