Analysis of Physical Friction Characteristics about Handwrite Feeling—Rough and Smooth

Writing was an important factor in human society since long time ago. And previous studies indicate many consumers evaluate pens in handwriting feeling above all other factors when they select recently pens. The fact they work always grabbed in hands considered, the emotional design of writing tools is essential. However, the feeling such as handwriting feelings is gradually disappearing due to the development of mobile devices. So we thought that the need for an engineering approach. The technology of the sense of touch belongs to the technology of the sensibility field, but it is positively necessary to objectify the sense of touch in order to develop new technologies or products by expressing this numerically and applying it to engineering. In order to objectify the sense of touch, the variables (the pressure, temperature, texture of material, etc.) of the friction when the stylus pen first touches the surface of the object should be digitized. And static and dynamic friction models should be established and the variables that affect the friction behavior should be organized. This study investigated the handwriting feeling of various writing tools and attempted to use it for the development of new mobile devices in the future through physical friction test. This study investigated the handwriting feeling of various writing tools and attempted to use it for the development of future mobile devices through physical friction test. Using developed model which can explain how the experimental parameters and emotional user experience, developer can design their product which can give user expected emotional sensibility.
