This report focuses on a surface analysis system used to measure mechanically physical properties of tissue surfaces and the impact that these surface properties have on human perceived softness. Previous studies on passive and active touch provide important information related to human tactile sensitivity. Passive touch relies on vibrotactile stimulation of the finger tip by moving a probe against a stationary skin surface.
Active touch involves tactile exploration of an object.
Active touch stipulates that the person involved in the sensitivity study has control over the touching process. Standard test procedures enhance the MSSA system operation by dictating the hardware default settings and sample fixturing. The design of FITS was based on active touch studies as much as possible. Human subjective data were gathered on all selected tissue samples Simple and multiple regression analysis was performed using the human data.
