The first embodiment is as follows: please refer to fig. 1-7, which illustrate an interactive display device for a screen, comprising a display screen 10, a signal emitting module, a viewing angle sensing module 20, a distance sensing module 30, and a control module.
The display screen 10 is rectangular and at least one piece in number, the display interface of the display screen 10 is virtually divided into a plurality of display partitions with basic sizes, and a plurality of display contents are released on the display screen 10; each of the delivered content is delivered based on at least one of the display partitions.
The signal emitting module uses infrared glasses as shown in fig. 13-15 in the present application; a plurality of infrared emitters are distributed around the frame of the infrared glasses; the emitting directions of the infrared emitters on each side of the mirror frame are different, and only one of the infrared emitters on each frame is started each time; infrared rays emitted by the infrared emitters of the upper frame face the upper side, infrared rays emitted by the infrared emitters of the lower frame face the lower side, infrared rays emitted by the infrared emitter of the left frame face the left side, and infrared rays emitted by the infrared emitter of the right frame face the right side; the emission angle of each infrared emitter is different; the infrared emitters of the upper frame and the infrared emitters of the lower frame form a vertical emission group, and the range of the infrared emission angle of the vertical emission group is shown in fig. 14; the infrared emitter of the left frame and the infrared emitter of the right frame form a transverse emission group, and the range of the infrared emission angle of the transverse emission group is shown in fig. 15; it should be noted that an infrared glasses product with a plurality of controllable infrared emission angles belongs to the prior art, and refer to a medical infrared glasses with patent number CN 201821791880.9; therefore, the specific structure of the infrared glasses is not described in detail in the present application; in the present application, the plurality of infrared emitters on each side are activated one at a time to map four light spots on the plane of the display screen 10, and the four light spots form a virtual cross line with two perpendicular lines, as shown in fig. 1; the center of the cross line is regarded as the sight focus of the screen viewer.
The visual angle sensing module 20 is an infrared receiving screen formed by combining a plurality of infrared receivers, the infrared receiving screen is distributed on the periphery of the rectangular display screen 10 and is in seamless fit with the periphery of the display screen 10, and an infrared receiving surface of the infrared receiving screen and a display interface of the display screen 10 are located on the same plane; the cross line mapped by the infrared glasses is mapped on the plane; the infrared receiving screen is virtually divided into a plurality of induction subareas, each induction subarea corresponds to one display subarea, and the display subareas corresponding to the induction subareas are display subareas positioned on the peripheral edge of the display screen; in the present embodiment, the display screen 10 is virtually divided into four basic display partitions with the same structure and size, as shown in fig. 2; the infrared receiving screen is virtually divided into four basic induction subareas with the same structure and size, and the induction subareas are positioned outside the display screen 10, as shown in fig. 2; in the present application, the distances from each light spot of the cross connecting line to the center are all consistent and are regarded as a, the basic display partition is a square, the side length is regarded as b, and the length size relationship between a and b is as follows: b is more than a and less than 2b; in addition, the width of the sensing subarea is more than twice a, so that when the sight focus of a viewer is positioned in the display screen, the sight focus is always within the range surrounded by the sensing subareas.
The distance sensing module 30 is a plurality of sensors located on the ground, the sensors may be force sensors, light sensors, etc., and the sensors are used for sensing the distance and angle of the viewer relative to the display screen 10; the distance sensing module covers a screen viewing range in front of the display screen 10 and divides the screen according to the distance relative to the display screen 10; it should be noted that the control module determines that the display screen 10 has the viewer and the infrared emitter is activated only when the viewer is within the sensing range of the sensor.
The control module comprises a central controller, and the central controller is used for receiving and controlling the specifically started infrared emitter in the infrared glasses according to the sensing signal of the sensor of the distance sensing module 30; the size of a virtual cross connecting line formed by light spots mapped on the plane of the display interface after the infrared emitter emits infrared rays is controlled in the sight direction of a screen viewer, so that the size of the cross connecting line projected on the display interface by the infrared rays emitted from farther away is prevented from being larger; the control module determines the position of the sight focus of the screen viewer on the display screen 10 according to the specifically triggered basic induction subarea; the control module controls the display screens to adjust the number of display partitions occupied by any display content and transfer the released content among the display screens.
When the visual focus of the viewer is located at the center of the basic display partition located at the upper left corner of the display screen 10, as shown in fig. 2, the light spot located at the upper side and the light spot located at the left side in the cross-shaped connection line are both mapped in the corresponding basic sensing partition of the basic display partition located at the upper left corner, and the light spot located at the right side and the light spot located at the lower side in the cross-shaped connection line are both mapped in the display screen 10, so that two light spots of the four light spots trigger the basic sensing partition, and the triggered basic sensing partitions are the same;
when the visual focus of the viewer moves from the position shown in fig. 2 to the lower right corner of the basic display partition located at the upper left corner of the display screen 10, as shown in fig. 3, if the central controller controls to replace the activated infrared emitter, and the angle of infrared emission is more outside, the unqualified state shown in fig. 3 is exhibited; an acceptable state should be a light spot on the lower side within the display screen 10, rather than in the underlying sensing sub-area on the lower side, because b < a < 2b, the width of the sensing sub-area is more than twice a.
When only one person is present for the screen viewer and the focal point of the line of sight of the screen viewer is located in a certain basic display partition, taking the basic display partition located at the lower left corner as an example, as shown in fig. 5, the content of the display partition is enlarged to the full screen of the display screen 10, and if the display content needs to enter the link content to view the specific content, the display screen 10 displays the link-entered content.
When the number of screen viewers is multiple, the focus of the line of sight of the screen viewers is located in some two basic display partitions, and the number of the screen viewers corresponding to the two basic display partitions is the same, taking the basic display partitions located at the lower left corner and the upper right corner as an example, as shown in fig. 6, the contents of the two display partitions are all enlarged in the same proportion until the two display partitions are expanded to be full of the display screen 10, and if the display content needs to enter the link content to watch the specific content, the display screen 10 displays the content entering the link.
When the number of screen viewers is multiple, the focus of the line of sight of the screen viewers is located in some two basic display partitions, and the number of screen viewers corresponding to the two basic display partitions is different, taking the basic display partitions located at the lower left corner and the upper right corner as an example, as shown in fig. 7, the released content of the display partition at the lower left corner with the large number of screen viewers is amplified to be full of the full screen, and the released content of the display partition at the upper right corner with the small number of other screen viewers is transferred to another display screen 10 relatively far away from the screen viewers for releasing.
The second concrete embodiment: on the basis of the first embodiment, please refer to an interactive display device for screens shown in fig. 8-9, in order to further subdivide the display interface of the display screen 10, when the number of the basic display partitions is greater than four, the display screen 10 is divided into nine basic display partitions in the present embodiment; as shown in fig. 8, the base display section located at the center of the display screen 10 is without the corresponding base sensing section; the basic display subareas positioned at the outer edge of the display screen 10 are provided with corresponding basic induction subareas, wherein the occupied area of the corresponding basic induction subareas of the basic display subareas positioned at the corners is larger than that of the corresponding basic induction subareas of the basic display subareas positioned at the waist;
when two light spots exist in the same basic induction partition at the same time, the sight focus is judged to be in the basic display partition positioned at the corner, and the specific basic induction partition positioned can be judged according to the position of the triggered basic induction partition;
when only one basic sensing partition is triggered and only one light spot exists in the basic sensing partition, as shown in fig. 8, it is determined that the sight line focus is located in the basic display partition located at the waist, and specifically, which basic sensing partition is located can be determined according to the position of the triggered basic sensing partition;
when two different basic induction subareas are triggered and only one light spot exists in each of the two basic induction subareas, judging that the sight line focus is in the basic induction subarea and is not in the display interface of the display screen 10;
when no basic sensing partition is triggered, as shown in fig. 9, the sight focus is determined to be located in the basic display partition in the middle;
it should be noted that, since there are a plurality of presentations displayed on the display screen 10, and at least one of the presentations should be of interest to the viewer, the probability that the viewer's gaze focus is located in the sensing area or outside the sensing area is very small after standing on the sensor, and in this embodiment, the applicant considers such a small probability event.
And when the basic display subarea is only one display subarea occupied by the released content, the central controller takes the whole released content as an object to expand the enlarged display area.
The third concrete embodiment: referring to the interactive display device for screen in fig. 10, the distance sensing module 30 is configured to perform partitioning in a direction (longitudinal direction) away from the display screen 10 and in a direction (transverse direction) parallel to the display screen 10, in addition to partitioning in a direction (longitudinal direction) away from the display screen 10; as shown in fig. 10, the sensing range of the distance sensing module 30 is divided into nine regions in the present embodiment; in the longitudinal direction, the farther the viewer is from the display screen 10, the closer the angle of infrared emission is to the longitudinal direction; in the transverse direction, the farther the viewer is from the center of the display screen 10, the closer the angle of infrared emission approaches the transverse direction; the projection size of the infrared glasses on the plane of the display interface is consistent no matter where the screen viewer is located in the sensing range.
The fourth concrete embodiment: on the basis of the second or third embodiment, please refer to fig. 11-12, in which the size of the display partition is proportional to the size of the cross-connecting line, i.e. the larger the range of the display partition is divided, the larger the size of the corresponding cross-connecting line is, so as to ensure that the relationship between the length of a and the length of b is: b < a < 2b, and the width of the induction subarea is more than twice a.
In order to further subdivide the display interface of the display screen 10, the number of the basic display partitions may be greater than nine, taking the basic display partition as a 5 × 5 array as an example, as shown in fig. 11, the basic display partition without the corresponding basic sensing partition has nine located in the middle; therefore, when only embodiment two or three is applied, when the viewer is within the sensing range and no basic sensing section is triggered by infrared rays, the central controller cannot determine which of the nine basic display sections the focus of the line of sight is located; the embodiment discloses a method for determining the sight focus of a screen viewer under the condition, which comprises the following steps:
s10, combining a plurality of basic display subareas to enlarge the size of each display subarea by one level, as shown in FIG. 12, combining four basic display subareas into a new display subarea in the embodiment, and adjusting the started infrared emitter by the control module to enlarge the size of a mapping result mapped on a plane where the display screen is located by one level, namely, the size of the mapping result corresponds to the size of the new display subarea;
s20, detecting whether any induction partition is triggered by a light spot; if not, indicating that the sight focus is positioned in the original basic display partition at the middle part, and circulating the step S10; if yes, the sight line focus is positioned in a new display partition, and the sight line focus of the screen viewer is judged to be positioned in the newly expanded display partition range, and step S30 is carried out;
and S30, eliminating the original basic display subareas with the corresponding induction subareas in the new large display subareas, and reducing the range of the sight focus of the viewer to the range of the original basic display subareas without the corresponding induction subareas in the new display subareas.
And when the basic display subarea is only one display subarea occupied by the released content, the central controller takes the whole released content as an object to expand the enlarged display area.
It should be noted that, the method described in this embodiment is also applicable to the determination of the visual focus position in the state where the basic display partition is further subdivided.
The fifth concrete example: on the basis of any one of the first to fourth specific embodiments, when the number of screen viewers is multiple and the number of screen viewers corresponding to different released contents is inconsistent, the attention degree of the released contents is graded, and the higher the attention degree of the released contents is, the larger the display area of the display screen is occupied; when the released content needs to enter the link content to watch the specific content, displaying the corresponding link content by each concerned released content; when the attention of the highest-level released content exceeds the attention of the next-highest-level released content by at least two levels, the control module controls the highest-level released content to fill the full screen of the display screen, the rest released content is transferred to a second display screen for display, and the occupied area ratio of each released content on the second display screen is consistent with the attention ratio of each released content.
