Information display device

摘要

An information display device includes: an image display unit that displays an image according to an orientation of a display screen; a terminal posture detection unit that detects a posture of the device using an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor; and a display direction determination unit that determines whether or not the posture of the device changes, and determines the orientation of the display screen. In the case where the display screen is substantially horizontal and the posture of the device changes, the orientation of the display screen is determined so that, when the device moves by a predetermined angle or more with respect to the orientation (reference orientation) of the display screen before the determination of the posture change, a side of the device at the predetermined angle or more from the reference orientation corresponds to the top of the display screen.

主权项

1. An information display device comprising:
a processor; and a non-transitory memory having stored thereon executable instructions, which when executed, cause the processor to perform:
displaying an image according to an orientation of a display screen of the information display device, the display screen having a plurality of sides constituting edges of the display screen, the orientation being an orientation where a first side of the display screen among the plurality of sides corresponds to a top of the display screen;detecting a posture of the information display device based on information obtained by an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor;detecting a centrifugal force direction based on information obtained by the acceleration sensor; anddetermining whether or not the posture of the information display device changes, and determining the orientation of the display screen, wherein in the case where (i) the display screen is in a substantially horizontal state, (ii) the posture of the information display device is determined to have changed, and (iii) the information display device moves by a predetermined angle or more with respect to a reference orientation which is the orientation of the display screen before the posture of the information display device is determined to have changed, the orientation of the display screen is determined so that a side of the information display device corresponds to the top of the display screen, the side of the information display device corresponding to a second side of the display screen different from the first side of the display screen in a direction of the predetermined angle or more from the reference orientation, wherein in the case where (i) the display screen is in the substantially horizontal state, (ii) the centrifugal force direction is detected, and (iii) the posture of the information display device is determined to have changed, the orientation of the display screen is determined so that a side of the information display device farthest in the detected centrifugal force direction corresponds to the top of the display screen, and wherein the image is displayed according to the determined orientation of the display screen such that a top of the image corresponds to the top of the display screen.
