PORTABLE ELECTRONIC DEVICES AND METHODS OF USING THE SAME

Description

FIELD

The present disclosure generally relates to consumer electronics, and more particularly to portable electronic devices and methods of using the portable electronic devices.

BACKGROUND

Portable electronic devices in current market usually include a rectangular display screen, and these portable electronic devices display information in two different orientations: a landscape view mode where the width of the screen display is greater than the height of the screen display, and a portrait view mode where the height of the screen display is greater than the width of the screen display. People generally prefer to view information on the display screen in landscape mode especially for displaying images and/or videos. When the display screen shows an article, it shows more characters in each line than the portrait mode. Many portable electronic devices such as smartphones, tablet computers, or electronic readers have an ability to allow user to select the display orientation by turning the display screen from one mode to another. However, most of these portable electronic devices include an accelerometer to detect the turnings and automatically adjusting the orientation of the display screen. Such automatic adjustments work well when a user is in upright position. When the user turns the display screen sideways when the user is laying down in horizontal position, such automatic adjustments will not work well, and will not maintain the landscape view mode unless the user locks the display screen orientation. As we all know there are options on digital display devices such as an iPad, or Microsoft Surface, where user can lock the orientation of the display screen as landscape view. However, once you lock into a landscape view, there are always two possibilities because the landscape view can be displayed in upright landscape view or upside-down landscape view, therefore, the user has to orient him/herself to see the upright landscape view. It is desirable to develop a display orientation control mechanism to set the default display mode into the landscape view mode based not on direction of gravity, but on the more natural observation of the orientation of the user's head.

Therefore, a heretofore unaddressed need still exists in the art to address the aforementioned deficiencies and inadequacies.

SUMMARY

In one aspect, the present disclosure relates to a portable electronic device. In certain embodiments, the portable electronic device includes: a set of display event detection sensors, a display orientation control module, and a display screen. The set of display event detection sensors is used for detecting one or more display events on the display screen of the portable electronic device. The display orientation control module sets an orientation of a display screen of the portable electronic device to always maintain a landscape view of a display on the portable electronic device for the user when at least one display event is detected by the set of display event detection sensors. The display orientation control module includes a processor, and a non-volatile memory. The non-volatile memory stores an operating system and a display orientation control application. The display orientation control application includes: an event detection module and a display module. When the display orientation control application is executed by the processor, the display orientation control application causes the processor to perform:

- detecting, by the set of display event detection sensors, an orientation of the user's face, and
- setting, when at least one of the set of display event detection sensors detects at least one display event, by the display module the orientation of the display screen of the portable electronic device to the landscape view on the portable electronic device to ensure an upright landscape view is displayed according to the orientation of the user's face detected. When the portable electronic device is positioned horizontally or tilted in an angle relative to user's face, a top edge of the landscape view of the display aligns with the user's face. When the portable electronic device is positioned vertically relative to user's face, the right edge of the landscape view of the display aligns with the user's face.

In certain embodiments, the portable electronic device includes: a lightweight, electrically-powered electronic device functionally capable of communications, data processing and data utility.

In certain embodiments, the portable electronic device may also include an image enhancement device.

In another aspect, the present disclosure relates to a method of using a portable electronic device. In certain embodiments, the method includes: installing a display orientation control application having an event detection module and a display module on the portable electronic device, starting the display orientation control application, and connecting a set of display event detection sensors to the event detection module to detect one or more display events. In certain embodiments, the method also includes: detecting, by the set of display event detection sensors, an orientation of the user's face, setting, when at least one of the set of display event detection sensors detects at least one display event, by the display module, the orientation of the display screen of the portable electronic device to the landscape view on the portable electronic device to ensure an upright landscape view is displayed according to the orientation of the user's face detected. When the portable electronic device is positioned horizontally or tilted in an angle relative to user's face, a top edge of the landscape view of the display aligns with the user's face. When the portable electronic device is positioned vertically relative to user's face, the right edge of the landscape view of the display aligns with the user's face.
