Relationship between Surface Property and Operability of Tablet Terminal with Touch-Sensitive Screen

Intuitively operated touch-sensitive screens are becoming more prevalent in our daily lives. Particularly, the rapidly growing demand for tablets, which are beginning to be used in the educational and medical environments, is said to be leading the market. However, it has been pointed out that it is hard to slide a finger easily on the tablet screen when operating the device, making it difficult to use the device. The present study investigates the relationship between the surface property of a tablet touch-sensitive screen and the easiness of sliding a finger on the screen, and evaluates the influence of the surface property on the operability based on the experimental results.
