Abstract

Provided to approximate the sensation of actually writing on a writing medium when using a pen-type input device. An information processing system is configured to detect the speed and direction of movement of the pen tip of a pen-type input device on an operable surface as contact parameters, to calculate a feedback level corresponding to the current time based on a predetermined equation using the velocity at the current time for a case of a non-reversed state where the direction is not reversed between a predetermined time previous to the current time and the current time, to calculate the feedback level based on an equation into which the velocity at the current time is substituted as zero for a case of a reversed state where the direction is reversed between the predetermined time previous to the current time and the current time, and to drive a haptic reproduction unit in the pen-type input device based on the calculated feedback level.
