Method for viewing a presentation document in a mobile device and a system thereof
View Patent ↗Provided are a method for viewing a presentation document in a mobile device and a system thereof. The method includes the steps of: determining an orientation of screen according to a sensing signal from a gravity sensor; displaying slide thumbnails of the presentation document at the lower part of the screen in a horizontal arrangement when the screen orientation is portrait; and displaying the slide thumbnails of the presentation document at the left part or the right part of the screen in a vertical arrangement when the screen direction is landscape. When a user opens a presentation document, the method for viewing a presentation document in a mobile device according to the present invention switches display mode of slide thumbnails in the presentation document automatically according to the screen orientation sensed by a gravity sensor, thereby being able to display the slide thumbnails in a more suitable manner according to different screen orientations, and facilitating the viewing and operation of the presentation by a user. The display manner in the method of the present invention better conforms to the psychological expectation of users, and can result in a better user experience.
1. A method for viewing a presentation document in a mobile device, characterized in that the method comprises the steps of:
determining an orientation of a screen according to a sensing signal from a gravity sensor;
displaying thumbnails of slides in the presentation document at lower part of the screen in a horizontal arrangement when the orientation of the screen is portrait; and
displaying the thumbnails of the slides in the presentation document at left part or right part of the screen in a vertical arrangement when the orientation of the screen is landscape;
wherein switching mode of a slide on focus is set as left/right sliding switching when the orientation of the screen is portrait; and the switching mode of the slide on focus is set as up/down sliding switching when the orientation of the screen is landscape, so that displaying of a slide main body is not blocked when sliding switching is performed;
wherein display mode of the slide on focus is switched to a portrait mode when the orientation of the screen is portrait; and the display mode of the slide on focus is switched to a landscape mode when the orientation of the screen is landscape.
2. A system for viewing a presentation document in a mobile device, characterized in that the system comprises:
an orientation sensing module, which is used to determine an orientation of a screen according to a sensing signal from a gravity sensor;
a thumbnail display switching module, which is used to display thumbnails of slides in the presentation document at lower part of the screen in a horizontal arrangement when the orientation of the screen is portrait; and to display the thumbnails of the slides in the presentation document at left part or right part of the screen in a vertical arrangement when the orientation of the screen is landscape; and
a sliding switching module for the slides, which is used to set switching mode of a slide on focus as left/right sliding switching when the orientation of the screen is portrait; and to set the switching mode of the slide on focus as up/down sliding switching when the orientation of the screen is landscape, so that displaying of a slide main body is not blocked when sliding switching is performed;
the system further comprises a display mode switching module, which is used to switch display mode of the slide on focus to a portrait mode when the orientation of the screen is portrait; and to switch the display mode of the slide on focus to a landscape mode when the orientation of the screen is landscape.
