FIG. 1 is a schematic view showing a user who watches an electronic device 100 for providing content according to a user's posture according to an exemplary embodiment.
According to an exemplary embodiment, the electronic device 100 may provide content to a user 110 and may control the content according to a posture of the user 110 who watches the content.
For example, the electronic device 100 may capture an image of the user 110, and when the posture of the user 110 in the image is acceptable, the electronic device 100 normally provides content. On the other hand, in an exemplary embodiment, when the posture of the user 110 is unacceptable, the electronic device 100 may distort the content change the content by controlling a content providing screen.
Here, the content providing screen or a content reproduction screen refers to controlling of content reproduction.
FIG. 2 is a schematic flow chart showing a content providing method according to an exemplary embodiment.
First, the electronic device 100 reproduces content (operation S210).
Here, the content is information provided to a user, and may include, for example, a video, a static image, or an audio signal. In addition, for example, the electronic device 100 may reproduce content such as a movie.
Next, the electronic device 100 generates an image by capturing a picture of the user 110 (operation S220).
Next, the electronic device 100 obtains information regarding a viewing posture from the image of the user (operation S230).
The information regarding the viewing posture is information obtained from a shape of the user 110 in the image. The information regarding the viewing posture may include, for example, a silhouette of the user 110, a skeleton, a shoulder line, and a neck line of the user 110, symmetric information, a position of eyes of the user 110, a depth of the image, and a distance between the electronic device 100 and the user 110.
Next, the electronic device 100 determines whether a posture of the user 110 is acceptable based on the information regarding the viewing posture (operation S240).
According to an exemplary embodiment, the shoulder line of the user 110 may be compared with a predetermined reference line. When an angle between the shoulder line of the user 110 and the reference line is equal to or more than a predetermined angle, it may be determined that the posture of the user 110 is unacceptable.
According to another exemplary embodiment, the electronic device 100 may transmit the image generated in operation S220 to a communication terminal 680 as shown in FIG. 6, which is communicatively connected to the electronic device 100. A user of the communication terminal 680 which receives the image from the electronic device 100 may input information regarding a reference posture to the communication terminal 680. For example, the user of the communication terminal 680 may input an outline of his or her desired posture as the reference posture. The communication terminal 680 may transfer the input information regarding the reference posture to the electronic device 100. In operation 240, the electronic device 100 may compare the information regarding the viewing posture obtained from the shape of the user 110 in the image generated in operation S220 with the reference posture to control the content reproduction screen. For example, when the information regarding the viewing posture does not correspond to the outline of the posture, i.e., the reference posture, received through the communication terminal 680, an image on the content reproduction screen may be distorted so that the content may not be normally provided. Therefore, it is possible to induce a correct posture of the user 110 by providing undistorted content only when the user 110 has the reference posture that is input to the communication terminal 680.
When the user's posture is determined to be unacceptable, the electronic device 100 controls the content reproduction screen (operation S250).
In this case, the electronic device 100 may control the content reproduction screen to assist the user 110 to correct his or her current posture into an acceptable posture.
FIG. 3 is a detailed flow chart showing the content providing method according to an exemplary embodiment.
First, the electronic device 100 reproduces content (operation S310).
The content to be reproduced may include image content such as a movie.
In addition, as shown in FIG. 10, the content to be reproduced may be content for assessing health of the user.
Next, the electronic device 100 generates an image by capturing a picture of the user 110 (operation S320).
Next, information regarding a viewing posture of the user is obtained from the image of the user (operation S330).
Here, according to an exemplary embodiment, the information regarding the viewing posture may include information regarding a skeleton of the user which is obtained from the image of the user.
Next, the electronic device 100 determines whether a posture of the user 110 is acceptable based on the information regarding a viewing posture (operation S340).
The information regarding the viewing posture may include information regarding the skeleton of the user. The information regarding the skeleton of the user may include information regarding an angle of a joint, an alignment of a shoulder skeleton, and the like.
In addition, according to an exemplary embodiment, information regarding the viewing posture may include a position of the eyes, a posture of an upper body, a shoulder line, a neck line, and symmetric information of a user's face obtained from the image of the user.
According to an exemplary embodiment, the electronic device 100 compares the information regarding the skeleton of the user, which is included in the information regarding the viewing posture, with reference information, and may determine whether the posture of the user 110 is acceptable according to the comparison result.
In addition, according to another exemplary embodiment, the electronic device 100 may determine whether the user's posture is inclined based on the position of the eyes, the posture of the upper body, the shoulder line, the neck line, the symmetric information of the user's face, and the like. When the user's posture is inclined at an angle that is equal or more than a reference value, the electronic device 100 may determine that the user's posture is not acceptable.
In addition, according to an exemplary embodiment, when the electronic device 100 determines that the user's posture is not acceptable, the electronic device 100 may transmit the image obtained by capturing an image of the user to the communication terminal 680.
For example, when the electronic device 100 determines that a posture of a child who views content is not acceptable, the electronic device 100 may transmit an image obtained by capturing a picture of the child to a predetermined communication terminal of a parent of the child to allow the parent to correct a viewing posture of the child.
Next, when the electronic device 100 determines that the user's posture is not acceptable, the electronic device 100 controls an image on the content reproduction screen which is reproduced in S310 (operation S350).
In an exemplary embodiment, the image on the content reproduction screen may be distorted. For example, the electronic device 100 may output an image on the screen in which at least one of a definition, a resolution, a color tone, a chroma, and a brightness is changed, or an image layout is changed, or an image form is modified.
According to an exemplary embodiment, the electronic device 100 may output an image on the content reproduction screen of which resolution is changed as shown in FIG. 9B from that of a content reproduction screen as shown in FIG. 9A.
According to another exemplary embodiment, the electronic device 100 may output an image layout changed as shown in FIG. 9C from that of the content reproduction screen as shown in FIG. 9A.
In addition, the electronic device 100 may interrupt display of the image on the reproduction screen.
In addition, the electronic device 100 may generate a notification message to be output to the content reproduction screen.
According to an exemplary embodiment, the electronic device 100 may output the notification message as shown in FIG. 9D.
In addition, the content reproduction screen may be divided into a plurality of regions, and the content reproduction screen and the image obtained by capturing the user may be output to each of the regions.
According to an exemplary embodiment, when the user's posture is determined to be unacceptable while the image on the content reproduction screen as shown in FIG. 9A is output, the content reproduction screen may be divided as shown in FIG. 9E. The image on the content reproduction screen and the image obtained by capturing the user may be output to each of the regions.
Next, when the reproduction of content is not finished (operation S360), the electronic device 100 may capture the image of the user again (operation S320).
When the user's posture is determined to be acceptable in operation S340, original content that is reproduced in operation S310 is reproduced (operation S355).
For example, when a distorted image on the content reproduction screen is output in operation S350 and the user's posture became acceptable, the original undistorted content reproduced before the distortion may be reproduced in operation S355.
In another example, when the content reproduction screen interrupts displaying content in operation S350, the content may be again reproduced on the reproduction screen in operation 355.
In still another example, when the notification message is displayed on the content reproduction screen in operation S350, the notification message may be removed from the content reproduction screen in operation 355.
In still another example, when the content reproduction screen is divided into a plurality of regions and the image on the content reproduction screen and the image obtained by capturing the user are output to each of the regions in operation S350, the image on the content reproduction screen may be output to an entire screen in operation 355.
Next, when the reproduction of the content is completed, the content providing method ends (operation S360).
FIG. 4 is a flow chart showing a method of providing content for health assessment by using accumulated information regarding a viewing posture according to an exemplary embodiment.
First, the electronic device 100 may accumulate the information regarding the viewing posture which is obtained in operation S330 and store the information.
In addition, the electronic device 100 may calculate a statistical value with respect to the accumulated information regarding the viewing posture.
For example, the electronic device 100 may calculate the number of receiving of information regarding the viewing posture that is determined to be unacceptable by using the accumulated information regarding the viewing posture. In other words, the electronic device 100 may calculate the number of receiving of information regarding the viewing posture that is determined to be unacceptable from the accumulated information regarding the viewing posture during a predetermined period of time, e.g., one hour.
In another example, the electronic device 100 may obtain a statistic about whether the posture is not acceptable by determining which body part such as a shoulder or a waist is not in a correct posture by using the accumulated information regarding a viewing posture. In other words, it is possible to classify information regarding a viewing posture that is determined to be unacceptable depending on whether an unacceptable viewing posture is due to, for example, an inclined shoulder, a waist posture, or a neck posture and calculate the number of information regarding a viewing posture according to the classification.
Next, the electronic device 100 may output the information regarding a viewing posture which is accumulated and stored (operation S420).
For example, it is possible to output to a screen the information regarding a viewing posture that is accumulated and stored in a form of a table.
Accordingly, the electronic device 100 may provide content, e.g., content for health assessment, according to the information regarding a viewing posture which is accumulated and stored.
According to an exemplary embodiment, when the number of information regarding a viewing posture that is determined to be unacceptable is equal to or higher than a predetermined value, the content for health assessment may be provided.
For example, when the number of information regarding a viewing posture that is determined to be unacceptable during the content reproduction is equal to or higher than 10, it is possible to instruct the user to adopt a specific posture as shown in FIG. 10, and an image of the user in the new posture is captured, thereby providing the content for assessing the user's health.
Here, according to an exemplary embodiment, it is possible to allow the user to select content to be reproduced from a list of contents for health assessment, or the contents for health assessment may be immediately reproduced.
FIG. 5 is a flow chart showing a method of providing posture correcting content according to an exemplary embodiment.
First, the electronic device 100 obtains information regarding a user's posture (operation S510).
Here, the content for assessing the user's health may be reproduced during operation 510.
For example, as shown in FIG. 10, the information regarding a user's posture may be obtained by suggesting the user to adopt a specific posture and by capturing an image of the user in the suggested posture. In other words, the posture of the user in the image is compared with the reference posture, and information such as flexibility, the alignment of a shoulder line, and a degree of bending in a spine of the user may be obtained according to the comparison result.
In addition, according to an exemplary embodiment, the electronic device 100 may obtain gesture or voice information of the user as additional information, and may obtain information regarding a user's posture based on the information regarding a viewing posture and the additional information.
For example, as shown in FIG. 10, the information regarding a user's posture may include a posture that is difficult for the user to adopt determined by using, as additional information, a sound that the user produces when the user adopts a specific posture.
Next, the electronic device 100 may provide a posture correcting content according to the information regarding a user's posture (operation S520). For example, the electronic device 100 may compare the information regarding a user's posture with reference information. According to the comparison result, for example, when a user's waist posture is determined to be unacceptable, a posture correcting content with respect to the user's waist may be reproduced.
According to an exemplary embodiment, it is possible to allow the user to select the posture correcting content to be reproduced from a list of posture correcting contents, or the posture correcting content may be immediately reproduced.
Next, the electronic device 100 may transmit the posture correcting content to another electronic device so that the user 110 may receive the posture correcting content through another electronic device (operation S530).
For example, it is possible to allow the user to receive the posture correcting content from a TV through a tablet PC.
