Although terminologies used in the present specification are selected from general terminologies used currently and widely in consideration of functions, they may be changed in accordance with intentions of technicians engaged in the corresponding fields, customs, advents of new technologies and the like. Occasionally, some terminologies may be arbitrarily selected by the applicant(s). In this case, the meanings of the arbitrarily selected terminologies shall be described in the corresponding part of the detailed description of the specification. Therefore, terminologies used in the present specification need to be construed based on the substantial meanings of the corresponding terminologies and the overall matters disclosed in the present specification rather than construed as simple names of the terminologies.
In the present specification, a portable device may include at least one selected from the group consisting of a smartphone, a smart pad, a music player, a tablet computer, and a note book. In the present specification, a portable device may be able to include a display area in the front and the side of the portable device, respectively.
FIG. 1 is a diagram of a portable device according to one embodiment of the present specification. The portable device 10 can be held by a hand of a user or put on a different object 11. As shown in FIG. 1, a state that a front of the portable device is laid in a manner of facing upwards or a display area positioned in the front of the portable device is facing the user can be defined as a first state of the portable device. The portable device may include a first display area 12 in the front and may include a second display area 13 in the side of the portable device. In this case, the first display area 12 may be able to include a wider display area compared to the second display area 13.
The portable device may be able to include the first display area 12 and the second display area 13 distinguished by at least one edge of the portable device as shown in the top of FIG. 1. An internal angle between the first display area 12 and the second display area 13 may have a value greater than 90 degrees and less than 180 degrees. As a different embodiment, the portable device may be able to include a second display area 13 in a form of a curved surface connected to the first display area 12 as shown in the bottom of FIG. 1. The second display area 13 can be positioned at the side of the portable device in a manner of being connected to the first display area 12 without a boundary line.
In case that a notification is generated, the portable device 10 may be able to display a content of the notification in at least one of the first display area 12 and the second display area 13. The portable device may be able to display a detail content of the notification in the first display area and a summary content 14 of the notification in the second display area 13. The portable device may be able to display the detail content of the notification in the second display area as well. In this case, the portable device may be able to provide the detail content of the notification to the user in a manner of scrolling the content displayed in the second display area. The operation of displaying the content by scrolling performed by the portable device shall be described in FIG. 5 and FIG. 6.
FIG. 2 is a diagram of a portable device providing a reflection image according to one embodiment of the present specification. The portable device 10 may be laid on an object 11 in a manner of being upside down. As shown in the top of FIG. 2, a state that a front of the portable device is laid in a manner of facing downwards or a display area positioned in the front of the portable device is not facing the user can be defined as a second state of the portable device. The portable device may be able to temporarily maintain the first display area 12 as an inactive state in the second state. The portable device may be able to display the content of the notification using the second display area 13. The second display area of the portable device is positioned at the side of the portable device and an internal angle between the first display area 12 and the second display area 13 may have a value greater than 90 degrees and less than 180 degrees. Hence, the content displayed in the second display area can be reflected in the object 11 by the portable device. In this case, if the portable device maintains the content displayed in the second display area as it is in the first state, a first reflection image 21 reflected in the object may indicate a result that a left and right of the content are reversed. The first reflection image 21 reflected in the object 11 can be checked by a vision of the user as of a state that the left and right of the content are reversed.
The portable device may be able to display the content displayed in the second display area in the first state by reversing the left and the right of the content in the second state as shown in the bottom of FIG. 2. The left-right reversed content is reflected in the object 11 by the portable device and the portable device may be then able to provide it to the user. By doing this, the user may be able to check a second reflection image 22, which is reflected in the object and not reversed the left and the right of the content, with the vision of the user. As mentioned in the foregoing description, the portable device senses a state of the portable device and may be then able to provide the content of a notification to the user using a content displayed in the second display area in the first state and using a reflection image, which is generated by reflecting a content displayed in the second display area in a surrounding object, in the second state.
FIG. 3 is a diagram of an operating method of a portable device using a reflection image according to one embodiment of the present specification. The portable device may be able to detect a control input 32 controlling a second reflection image 31 in the second state as shown in the top of FIG. 3. The portable device may be able to detect the control input controlling the reflection image 31 using a sensor unit. In this case, the control input may include at least one selected from the group consisting of a touch input by a hand of a user, a voice input, and a gesture input. The portable device may be able to detect the control input using at least one selected from the group consisting of a proximity sensor, a light sensor, a microphone, and a camera included in the sensor unit.
The portable device may be able to display the detail content of the notification in response to the control input 32 controlling the second reflection image 31. As described in the bottom of FIG. 2, the portable device may be able to display the detail content of the notification in a manner of reversing the left and right of the detail content of the notification. The left-right reversed detail content, which is displayed in the second display area, can be reflected in the object 11 by the portable device as a third reflection image 33. By doing this, the user checks the third reflection image 33 with vision and may be then able to identify the detail content of the notification. And, as a different embodiment, the portable device may be able to display a next content or delete a content currently displayed in response to the control input.
FIG. 4 is a diagram of a method of displaying a content according to a state of a portable device according to one embodiment of the present specification. FIG. 4 indicates a side view of the portable device. Referring to the top of FIG. 4, the portable device in the first state may be able to display the content of the notification in the second display area 13 without reversing the left and right of the content of the notification or reversing the top and bottom of the content of the notification. An image displayed by the portable device in the first state can be defined as a first image 41.
The portable device may be able to detect that the portable device is upside down as shown in FIG. 2. The portable device may be able to sense that a state of the portable device corresponds to the second state using a sensor unit. If the portable device in the second state maintains the first image displayed in the second display area 13 in the first state as it is, the content of the notification can be identified by the user as a second image 42, which is the image reversed the top and bottom and the left and right of the first image, as shown in the middle of FIG. 4. If the second image 42 displayed in the second display area 13 is reflected in the object by the portable device, the user may be able to check the first reflection image 21 of FIG. 2 with a vision. Since the first reflection image corresponds to a state that the left and right of the content of the notification is reversed, it is difficult for the user to check the content of the notification via the first reflection image.
The portable device may be able to display a third image 43 in the second display area 13 in a manner of reversing the left and right of the content of the notification in the second state. The third image 43 can be reflected in the object by the portable device. The second reflection image 22, which is the third image 43 reflected in the object, can be displayed as shown in the bottom of FIG. 2. In particular, the second reflection image 22 can be identified by the user similar to a case that the portable device in the first state displays the first image 41 in the second display area. In particular, the portable device may be able to provide the user with the content of the notification, which is not reversed the top and bottom or the left and right of the content of the notification, irrespective of the first state and the second state. In particular, the portable device in the second state may be able to provide the user with the content, which is not reversed the top and bottom or the left and right of the content, in a manner of reversing the left and right of content of the notification and then reflecting it in the object.
FIG. 5 is a diagram of a method of determining a scroll direction of a content according to one embodiment of the present specification. FIG. 5 indicates a side view of the portable device. Referring to the top of FIG. 5, the portable device in the first state may be able to display the content of the notification in the second display area 13 without reversing the left and right or the top and bottom of the content of the notification. By doing this, a user may be able to identify the content of the notification in the second display area of the portable device. An image displayed by the portable device in the first state can be defined as a first image 51. In case that a whole content of the notification cannot be displayed in the second display area 13 at one time, the portable device may be able to display a part of the content in the second display area 13 as the first image 51. The portable device may be able to display the whole content of the notification in a manner of scrolling the first image 51 displayed in the second display area 13. Referring to the top of FIG. 5, the portable device may be able to display the whole content of the notification in a manner of scrolling the displayed first image in a first direction 52.
In this case, the first direction can be determined in response to a direction to which a user reads a text. For instance, if a displayed content corresponds to an English text, the portable device may be able to display the whole content of the notification in a manner of scrolling the first image 51 in a left direction.
The portable device may be able to detect that the portable device is upside down as shown in FIG. 2. The portable device may be able to sense that a state of the portable device corresponds to the second state using a sensor unit. As shown in the middle of FIG. 5, a second image 53 displayed in the portable device in the second state can be identified by the user as an image that the left and right and the top and bottom of the first image is reversed. If the second image displayed in the second display area 13 is reflected in the object by the portable device, as described in FIG. 2, the user may be able to check the first reflection image 21 with vision. Since the first reflection image 21 corresponds to a state that the left and right of the content of the notification is reversed, it is difficult for the user to check the content of the notification via the first reflection image 21. In particular, the first reflection image 21 has a low visibility.
And, the portable device may be able to scroll the second image 53. As shown in the middle of FIG. 5, if the portable device in the second state maintains the first scroll direction 52, the user may be able to identify that the content moves to a second scroll direction 54 since the portable device is in the second state, which corresponds to a state that the portable device is upside down. The second scroll direction can be an opposite direction to the first scroll direction 52, which scrolls the content displayed in the first state. Since the second scroll direction is applied to the first reflection image 21, even in case that the user looks at the first reflection image 21, the first reflection image 21 can be scrolled in the opposite direction of the first scroll direction 52. Hence, the user may feel uncomfortable when the user reads a text, since the direction of reading the text has changed. In order to solve the inconvenience, the portable device may be able to change a method of displaying an image and a scroll direction in the second state.
The portable device may be able to display a third image 55 in the second display area 13 in the second state in a manner of reversing the left and right of the content of the notification. The third image can be reflected in the object by the portable device. As shown in the bottom of FIG. 2, the second reflection image, which is the third image 55 reflected in the object, can be identified by the user similar to a case that the portable device in the first state displays the first image in the second display area. In particular, the portable device may be able to provide the user with the content of the notification, which is not reversed the top and bottom or the left and right of the content of the notification, irrespective of the first state and the second state. In particular, the portable device in the second state may be able to provide the user with the content, which is not reversed the top and bottom or the left and right of the content, in a manner of reversing the left and right of the content of the notification and then reflecting it in the object. And, the portable device may be able to scroll the third image 55 in a third scroll direction 56 in the second state. By doing this, the portable device may be able to provide to the user with a content scrolled in the same direction of the first scroll direction 52 scrolling the content displayed in the first state. In this case, the third scroll direction 56 recognized by the user may be identical to the first scroll direction 52. Yet, since the state of the portable device in the first state and the state of the portable device in the second state are different from each other, the second scroll direction 54 for the portable device may be opposite to the first scroll direction 52. Hence, the user may be able to read the naturally scrolled content, since the direction of reading the text has not changed.
As mentioned in the foregoing description, the portable device in the second state may be able to provide to the user with the content of not reversed the left and right or the top and bottom of the content in a manner of reversing the left and right of the content of the notification and then reflecting it in the object. And, the portable device may be able to enable the user to naturally read the reflected content in a manner of changing the scroll direction of the displayed content.
FIG. 6 is a diagram of a method of determining a scroll direction of content according to a different embodiment of the present specification. FIG. 6 indicates a side view of the portable device. Referring to the top of FIG. 6, the portable device in the first state may be able to display the content of the notification in the second display area 13 without any reversing. By doing this, a user may be able to identify the content of the notification in the second display area of the portable device. An image displayed by the portable device in the first state can be defined as a first image 61. In case that a whole content of the notification cannot be displayed in the second display area 13 at one time, the portable device may be able to display a part of the content in the second display area 13 as the first image 61. The portable device may be able to display the whole content of the notification in a manner of scrolling the first image 61 displayed in the second display area 13. Referring to the top of FIG. 6, the portable device may be able to display the whole content of the notification in a manner of scrolling the displayed first image in a first direction 62, which is upward.
The portable device may be able to detect that the portable device is upside down as shown in FIG. 2. The portable device may be able to sense that a state of the portable device corresponds to the second state using a sensor unit. As shown in the middle of FIG. 6, a second image 63 displayed in the portable device in the second state can be identified by the user as an image that the left and right and the top and bottom of the first image is reversed. If the second image 63 displayed in the second display area 13 is reflected in the object by the portable device, as described in FIG. 2, the user may be able to check the first reflection image 21 with vision. Since the first reflection image 21 corresponds to a state that the left and right of the content of the notification is reversed, it is difficult for the user to check the content of the notification via the first reflection image 21. In particular, the first reflection image 21 has a low visibility.
And, the portable device may be able to scroll the second image 63. As shown in the middle of FIG. 6, the user may be able to look at the second image 63 displayed in the second display unit 13. In this case, if the portable device in the second state maintains the first scroll direction 62, the user may be able to identify that the second image 63 moves to a second scroll direction 64 since the portable device is in the second state, which corresponds to a state that the portable device is upside down. The second scroll direction 64 can be an opposite direction to the first scroll direction 62, which scrolls the content displayed in the first state. Yet, if the user looks at the first reflection image 21, the first reflection image 21 can be scrolled in the first scroll direction 62. Since the first reflection image 21 is the result of reflection of the second image 63, both the first scroll direction 62 scrolling the first image in the first state and the scroll direction scrolling the first reflection image 21 in the second state can be identified by the user identically. Hence, the portable device may be able to maintain the scroll direction of images.
The portable device may be able to display a third image 65 in the second display area 13 in the second state in a manner of reversing the left and right of the content of the notification. The third image can be reflected in the object by the portable device. As shown in the bottom of FIG. 2, the second reflection image 22, which is the third image 65 reflected in the object, can be identified by the user similar to a case that the portable device in the first state displays the first image 61 in the second display area. In particular, the portable device may be able to provide the user with the content of the notification, which is not reversed the top and bottom or the left and right of the content of the notification, irrespective of the first state and the second state. In particular, the portable device in the second state may be able to provide the user with the content, which is not reversed the top and bottom or the left and right of the content, in a manner of reversing the left and right of the content of the notification and then reflecting it in the object. And, the portable device may be able to scroll the third image 65 in a third scroll direction 66 in the second state. By maintaining the first scroll direction 62 scrolling the content displayed in the first state in the second state as well, the portable device may be able to provide to the user with the content capable of being scrolled in the same scroll direction. Hence, the user may be able to read the naturally scrolled content, since the direction of reading a text has not changed.
As mentioned in the foregoing description, the portable device in the second state may be able to provide to the user with the content of not reversed the left and right or the top and bottom of the content in a manner of reversing the left and right of the content of the notification and then reflecting it in the object. And, the portable device may be able to enable the user to naturally read the reflected content in a manner of maintaining the scroll direction of the displayed content.
As mentioned earlier in FIG. 5 and FIG. 6, the portable device may be able to provide a reflection image in a manner of reversing the left and right of the displayed content and then reflecting it in the object. And, the portable device may be able to provide content to the user by changing a scroll direction according to whether the scroll direction of a displayed content is left-right or top-bottom. In particular, in case that the content is scrolled in left or right direction in the first state, the portable device may be able to change the scroll direction of the content to the opposite direction in the second state. And, in case that the content is scrolled in upwards or downwards in the first state, the portable device may be able to maintain the scroll direction of the content in the second state.
FIG. 7 is a diagram of a displaying position for a content of a portable device according to one embodiment of the present specification. The portable device may be able to control the position of the content displayed in the second display area according to the state of the portable device.
The top of FIG. 7 may indicate a method of displaying the content of the portable device in the first state. The portable device 10 may be able to include the first display area 12 and the second display area 13. The display area of the portable device can be divided into the first display area 12 and the second display area 13 by a boundary line 70.
The portable device may be able to display a content 71 displayed in the second display area 13 at the position near the boundary line 70 in the first state. In case that the portable device is in the first state, a line of vision of a user may be positioned at the front of the portable device. In case that the user gazes at the portable device in front of the portable device, sub areas included in the second display area 13 and situated at the side of the portable device 10 may have different visibilities, respectively. In particular, as shown in the top of FIG. 7, if the second display area 13 of the portable device is a curved surface, a first area near the boundary line 70 may have relatively high visibility compared to other areas among the second display area 13. On the contrary, an area far from the boundary line 70 may have low visibility. Hence, the portable device displays the content 71 to be displayed in the second display area 13 in the first sub area near the boundary line 70 in the first state and may be able to enhance the visibility of the content 71.
The bottom of FIG. 7 may indicate a method of displaying the content of the portable device in the second state. As mentioned earlier in FIG. 4 to FIG. 6, the portable device 10 may be able to display a left-right reversed content 72 in the second display area in the second state. In particular, the portable device may be able to control the content displayed in the second display area to enable a reflection image to be seen as a normal position.
The portable device may be able to display the content 72 displayed in the second display area 13 in a position apart from the boundary line 70 as much as a first distance in the second state. In case that the portable device is in the second state, as shown in FIG. 7, a user may be able to gaze at a reflection image 73, which is a result from reflecting the content displayed in the second display area in an object 11. In this case, the object 11 may corresponds to a floor on which the portable device is laid. In case that the user gazes upon the reflection image 73 reflected in the object 11, the reflection images of the sub areas, which are included in the second display area 13 situated at the side of the portable device 10, may have different visibilities, respectively.
As shown in the bottom of FIG. 7, if the second display area 13 of the portable device is a curved surface, a sub area near the boundary line 70 may have relatively low visibility compared to other areas in the second display area 13. In particular, since a first sub area near the boundary line 70 in the second display area has a very short distance from the floor, it is difficult for a user to check a reflected image. On the contrary, a second sub area apart from the boundary line 70 as much as the first distance in the second display area may have relatively high visibility. Hence, the portable device displays the content 72 to be displayed in the second display area 13 in the second sub area apart from the boundary line 70 as much as the first distance and may be able to enhance the visibility of the reflected image 73.
If the second display area 13 corresponds to a curved surface, the portable device may be able to control the first distance according to curvature. The portable device may be able to configure a sub area forming an angle with a floor in a prescribed range in the second display area 13 as a second sub area. And, when a content is displayed in the second display area, the portable device may be able to display the content in a manner of compensating for a visual distortion due to the curvature of the curved surface of the second display area.

The second display area can be positioned in the first display area in a manner of being contiguous or connected. The second display area may have a form of a flat or a curved surface. The second display area can be used for a sub display area.
The sensor unit 102 may be able to sense a state of the portable device. The sensor unit may be able to sense the state of the portable device using at least one selected from the group consisting of a proximity sensor, a light sensor, a gravity sensor, and a gyro sensor. The sensor unit 102 may be able to sense a state that a front of the portable device is laid in a manner of facing upwards or a display area positioned in the front of the portable device is facing a user as a first state of the portable device. And the sensor unit 102 may be able to sense a state that a front of the portable device is laid in a manner of facing downwards or a display area positioned in the front of the portable device is not facing the user as a second state of the portable device. The sensor unit may be able to deliver the information on the sensed state to the controller.
And, the sensor unit 102 may be able to detect a control input controlling a reflection image. In this case, In this case, the control input may include at least one selected from the group consisting of a touch input by a hand of a user, a voice input, and a gesture input. The sensor unit may be able to detect the control input using at least one selected from the group consisting of a proximity sensor, a light sensor, a microphone, and a camera.

In case that a sensed state corresponds to the first state, the portable device may be able to display the content of the notification in the first display area or the second display area of the display unit [S30]. If the information on the sensed state corresponds to the first state, the portable device may be able to display the content of the notification in the first display area or the second display area of the display unit. The portable device may be able to display a part of content of the notification or a whole content of the notification. In case of displaying the whole content, the portable device may be able to display the whole content in the first display area. In case of displaying a part of content, the portable device may be able to display a part of the content in the second display area. A user may be able to identify the displayed content of the notification by gazing upon the display area of the portable device.
In case that a sensed state corresponds to the second state, the portable device may be able to display the content of the notification in the second display area of the display unit in a manner of reversing the left and right of the content of the notification [S40]. The portable device may be able to reverse the left and right of the content displayed in the second display area in the second state. As described in FIG. 2 and FIG. 4, in case that the portable device is in the second state, instead of gazing upon the display area of the portable device, a user may be able to gaze at a reflection image, which is reflected in a different object by the portable device. In this case, the reflection image reflected in a different object in the second state that the front of the portable device is facing downwards can be identified to a user as a left-right reversed image. Hence, the portable device may be able to display the content of the notification in the second display area in the second state in a manner of reversing the left and right of the content of the notification.
FIG. 10 is a flowchart of a method of controlling a portable device according to a different embodiment of the present specification. The portable device may be able to detect a notification [S110]. The portable device may be able to detect incoming call reception, e-mail reception, message reception, schedule notification, and other alarm generation situation as the notification.
The portable device may be able to sense a state of the portable device using a sensor unit [S120]. As described in FIG. 8, the portable device may be able to sense whether the portable device is in the first state or the second state using the sensor unit. The portable device may be able to sense a state that a front of the portable device is laid in a manner of facing upwards or a display area positioned in the front of the portable device is facing the user as a first state of the portable device. And, the portable device may be able to sense a state that a front of the portable device is laid in a manner of facing downwards or a display area positioned in the front of the portable device is not facing the user as a second state of the portable device.
The portable device may be able to judge the state of the sensed portable device [S130]. The portable device may differently operate according to whether the sensed state is the first state or the second state.
In case that the sensed state corresponds to the first state, the portable device may be able to display the content of the notification in the first display area or the second display area of the display unit [S140]. The portable device may be able to display a summary content of the notification in the first display area. And, the portable device may be able to display detail content of the notification in the second display area. A user may be able to identify the content of the notification displayed in the first display area or the second display area with a vision.
In case that the sensed state corresponds to the second state, the portable device may be able to sense attribute of an object on which the portable device is laid [S150]. As described in FIG. 8, the attribute of the object may include at least one selected from the group consisting of a texture of the object, color, and reflexibility of a surface of the object. In the following description, the reflexibility among the attributes of the object is described with an example. The portable device may be able to sense the reflexibility of the object on which the portable device is laid. The portable device may be able to provide a reflection image reflected in the object to a user in the second state. Hence, the portable device may be able to check whether the visibility of the reflection image is secured in a manner of sensing the reflexibility of the object.
The portable device may be able to judge whether the reflexibility among the attributes of the object is greater than a first reflexibility [S160]. The portable device may operate differently depending on a case that the reflexibility of the object is greater than the first reflexibility or a case that the reflexibility of the object is less than the first reflexibility. In this case, the first reflexibility may mean a minimum reflexibility securing the visibility of the reflection image reflected in the object.
In case that the reflexibility of the object is greater than the first reflexibility, the portable display may be able to display the content of the notification in the second display area in a manner of reversing the left and right of the content of the notification [S170]. If it is judged that the visibility of the reflection image is secured, as described in FIG. 2, the portable device may be able to display the content of the notification in the second display area in a manner of reversing the left and right of the content of the notification. The portable device may be able to provide the content of the notification displayed in a manner of being reversed the left and right of the content to a user by reflecting it in the object. The user may be able to identify the reflection image with vision. Consequently, the user may be able to check the reflection image identical to the content of the notification displayed in the first state.
In case that the reflexibility of the object is less than the first reflexibility, the portable device may be able to generate an alarm [S180]. If it is judged that the visibility of the reflection image is not secured, the portable device may be able to generate an alarm. If the reflexibility of the object corresponds to a value not securing visibility, a reflection image hardly delivers information to a user. Hence, instead of displaying the content of the notification, the portable device generates an alarm. In this case, the alarm may include sound, vibration, and flashing a lamp.
As mentioned in the foregoing description, the portable device may be able to control the content of the notification to be displayed by sensing the state of the portable device. In particular, in case that the portable device is in the second state, visibility and readability of the content can be enhanced by displaying the content in the second display area in a manner of reversing the left and right of the content.
