1. An information display device, comprising:
a display unit configured to display information in a scroll region, which is provided in at least a part of a screen of the display unit, while scrolling the information;
an acceleration sensor configured to detect an acceleration applied to the information display device; and
a control unit configured to control a scroll speed, at which the information is scrolled in the scroll region, based on the acceleration detected by the acceleration sensor,
wherein upon a determination, based on the acceleration detected by the acceleration sensor, that a user of the information display device is walking, the control unit is configured to
decelerate the scroll speed, and
continue to scroll the information at the decelerated scroll speed which is greater than zero,
wherein upon a determination, based on the acceleration detected by the acceleration sensor, that the user of the information display device stops, the control unit is configured to accelerate the scroll speed, and
wherein the accelerated scroll speed upon the determination that the user stops is faster than the decelerated scroll speed upon the determination that the user is walking.
