| Outline of Final Research Achievements |
The friction characteristics of an index finger slid on a molecular-layer-coated surface was investigated using the laboratory-made tribometer that can measure friction force, normal load, and positional information simultaneously. Both a normal load and a speed dependencies of friction coefficient was represented as one approximated curve surfaces. Besides, the shear strength decreased with increasing film thickness on the Si surface, indicating that the surface state is a dominant factor in determining the friction characteristics of the finger.
As for a correlation between a response time of touch panel display and the mechanical data of the finger slid on the display, the delay of the response time probably induced the heavy feeling of the subjects, and this could be brought about a change to the mechanical data of the finger manipulation such as sliding speed.
