     DETAILED DESCRIPTION 
     In embodiments presented herein there are disclosed methods for controlling display of portable computing devices and to portable computing devices controlling an output presented on a visual display 
     Referring now to the drawings, and more particularly to  FIG. 1 , there is shown a block diagram of a portable computing device  10  for controlling an output  14  presented on a visual display  12 . The portable computing device  10  includes a visual display  12  presenting an output  14  and a detector  26  for detecting an orientation of the portable computing device  10 . The detector  26  may comprise an accelerometer. The orientation may be one of a portrait mode  16  and a landscape mode  18  or one of a substantially horizontal mode and a substantially vertical mode. The portable computing device  10  also includes a processing device  28  which is in communication with the visual display  12  and the detector  26 . The portable computing device  10  further includes a memory  30  for storing instructions which cause the processing device  28 : to detect the orientation of the portable computing device  10  as being one of the portrait mode  16  and the landscape mode  18 ; in the portrait mode  16 , to present a text content  20  on the visual display  12 , the text content  20  substantially comprising text data, the text content  20  further comprising a visual content  24  indicator  22  indicative of the existence of visual content  24  comprising at least one of graphics data, photo data and video data; in the presence of the visual indicator, to rotate the portable computing device  10  to the landscape mode  18 ; and in the landscape mode  18 , to present the visual content  24  on the visual display  12 . 
     Typical examples of a portable computing device  10  include electronic readers, smartphones, tablets, phablets and, more widely, may also refer to cell phones, portable music players and other handheld electronic devices. However, given the pace of technological advancements in this field, the terms “portable computing device” may embrace new technologies that do not exist now but in which the method described herein can be implemented as in existing portable computing devices. These new portable computing devices should be considered as possible variants of the portable computing device  10  described herein. 
     The memory  30  for storing instructions can be an optical memory, a magnetic memory, or other types of memories known in computer engineering to store instructions and data. The instructions stored on the memory usually include routines, programs, objects, components, data structures, etc., that perform particular tasks or implement particular abstract data types and cause other parts of the computing environment to interact (communication, data exchange) together. 
     The processing device  28  is an electronic device configured for performing calculations, executing tasks with respect to the instructions that are received and more generally, perform logical operations. 
     The visual display  12  for presenting an output  14  may comprise what is commonly called a screen. The screen can be of various types depending on the underlying technology. Some types of screen include emitting light (smartphones, tablets) whereas others do not (such as readers). Many portable devices comprise a touch-sensitive screen, although the method described herein can be implemented in a device in which this feature is absent. 
     The processing device  28 , the memory  30 , the detector  26  and the visual display  12  can be operatively connected through a system bus or any other type of communication channel known in computer engineering to transmit electric, magnetic or optical information between the components of a computing device. In an embodiment, one (or more) component is external to the portable computing device  10  and communicates with the other components using an electrical connection or a wireless communication. For example, the memory  30  may be a flash memory which is external to the portable electronic device  10  but electrically connected thereto. 
     The detector  26  is configured for detecting an orientation of the portable computing device  10 . In most prior art devices, when the orientation is detected as being mostly vertical, the visual display  12  a mode called portrait mode. Similarly, when the orientation is detected as being mostly horizontal, the visual display  12  a mode called landscape mode. This aims to present information (text data, pictures, etc.) in an orientation that is more comfortable for the user in both cases. In that sense, an orientation of the portable computing device may be considered as corresponding to a given display mode (portrait/substantially vertical and landscape/substantially horizontal). 
     In an embodiment of the present invention, when the orientation corresponds to a first display mode (which can be portrait, landscape, substantially vertical or substantially horizontal), instructions on the memory  30  are sent to present a text content  20  on the visual display  12 , the text content  20  substantially comprising text data, the text content  20  further comprising a visual content indicator  22  which indicates that visual content  24  exists. When the portable electronic device is sufficiently rotated so that the detected orientation corresponds to a second display mode (preferably the mode which is complementary to the first display mode, for example for passing from the portrait to the landscape mode), the change of orientation triggers the display of the visual content  24  on the visual display  12 , in accordance with instructions stored on the memory  30  which are sent to perform this task. Whereas prior art devices display the same text data in two orientations as the display mode changes, an embodiment of the portable electronic device  10  displays text data (comprising a visual indicator  22 ) in an orientation and the visual content  24  that corresponds to the visual indicator  22  in the other orientation. Various exemplary representations of the visual display  12  are illustrated in  FIGS. 4-37  and described below. 
     According to an embodiment, the text content  20  (comprising text data and visual content indicators  22 ) and the visual content  24  are both already downloaded and stored on the memory  30 . Therefore, upon a rotation of the portable electronic device  10  in the presence of a visual content indicator  22 , when loading the visual content which is to be displayed in the recently changed orientation, no network connection is required. It means that no internet connection is needed to download the visual content, since it is already pre-downloaded on the memory  30  of the portable computing device  10 . This feature allows the display of the visual content  24  when no connection with a communication network is established, like in the metro, in underground facilities, in remote places or simply when the user of the portable computing device has no internet package with a network provider. Of course, if a network connection is available, new content can be downloaded. 
     According to another embodiment and referring now to  FIG. 2 , there is shown a method  100  for controlling the output  14  presented on a visual display  12  of a portable computing device  10 . The method  100  includes a step  102  of detecting the orientation of the portable computing device  10  as being one of a portrait mode  16  and a landscape mode  18  and the step  104  of, in the portrait mode  16 , presenting a text content  20  on the visual display  12 , the text content  20  substantially comprising text data, the text content  20  further comprising a visual content indicator  22  indicative of the existence of visual content  24  comprising at least one of graphics data, photo data and video data. The method  100  also includes the step  106  of, in the presence of the visual indicator  22 , rotating the portable computing device  10  to the landscape mode  18 ; and the step  108  of, in the landscape mode  18 , presenting the visual content  24  on the visual display  12 . As mentioned above in reference with  FIG. 1 , the portrait mode  16  and landscape mode  18  may be interchanged, or may also be replaced by modes that are substantially vertical and substantially horizontal. 
     According to another embodiment and referring now to  FIG. 3 , there is shown a schematic illustration of the system  200  for controlling the output  14  presented on a visual display  12  of a portable computing device  10 .
