1. An electronic apparatus comprising:
- a touchscreen display; and
a display controller configured to display, on the touchscreen display, a locus of first contact input detected on the touchscreen display, wherein;
the display controller is configured to draw a first line corresponding to the locus of the first contact input, and to draw a second line, based on a prediction based on a first position of the first contact input, andthe display controller is configured to display the second line in addition to the first line on the touchscreen display for a first duration of time,wherein the display controller is configured to adjust a length of the second line in accordance with a difference between an angle of a first vector and an angle of a second vector, the first vector obtained from the first position and a second position where second contact input is detected before the first position, the second vector obtained from the first position and a third position where third contact input is detected before the first position and after the second position.

Abstract
According to one embodiment, an electronic apparatus includes a touchscreen display and a display controller. The display controller is configured to display, on the touchscreen display, a locus of first contact input detected on the touchscreen display. The display controller is configured to draw a first line corresponding to the locus of the first contact input, and to draw a second line, based on a prediction based on a first position of the first contact input. The display controller is configured to display the second line in addition to the first line on the touchscreen display for a first duration of time.
