The embodiment of the present invention is described in detail below with reference to the accompanying drawings, and the embodiment of the present invention provides a projection method, which can be applied to automatic adjustment of a projection direction and projection content according to an operation gesture of a user, and does not require the user to manually operate a projection device to perform operations such as steering, and has the characteristics of convenience in operation and simple structure.
Fig. 1 is a schematic flow chart of a projection method according to an embodiment of the invention. The projection method in the embodiment of the invention may include:
sensing an operation gesture of a user on the projection interface;
based on the operation gesture, adjusting a projection orientation and/or projection content.
In the embodiment of the present invention, the projection method may be applied to an electronic device with a projection function, where the electronic device may project content displayed thereon, and a projection module of the electronic device that performs a projection operation may automatically perform a transition of a projection direction, so as to change a projection direction, or may also change projection content thereof. For example, the electronic device in the embodiment of the present invention may be a mobile phone, an arbitrary computer device, or a projector.
When the projection operation is performed, the projection module of the electronic device may project the display content of the electronic device, or may project the received image. In the following embodiments of the present invention, the interface projected by the projection content is collectively referred to as a projection interface. In the embodiment of the invention, the electronic device may sense an operation of a user in the projection interface, such as a touch, a slide, a click, and the like on the display content on the projection interface, or a slide, a touch, and the like in the projection interface. After the operation gesture is detected, projection control may be correspondingly performed, such as adjusting the projection orientation, or adjusting the projection content.
Specifically, the sensing an operation gesture of a user in the embodiment of the present invention may include: the method comprises at least one of sensing a touch operation of a user on the projection interface, sensing a position of the operation gesture on the projection interface, and sensing a spatial orientation of the operation gesture.
For example, in the embodiment of the present invention, the projection content in the projection interface may be an operation interface currently displayed by the electronic device, and the operation interface includes an identifier such as an application icon, and a user may directly perform a touch operation on the identifier on the projection interface, such as a click operation and a long-time press operation, or the user may also perform a preset gesture on the projection interface, such as a sliding operation. The electronic device can be provided with a gesture sensing module, the gesture sensing module can sense the gesture operation of the user on the projection interface, and the electronic device generates a corresponding control instruction based on the gesture operation sensed by the gesture sensing module so as to execute the corresponding control operation. Or, the projection content in the projection interface according to the embodiment of the present invention may also be an image file received by the electronic device or the projection module, and the user may perform operations such as sliding on the projection interface.
When the gesture sensing module senses that the touch operation is clicking the corresponding application identifier, a first instruction for starting the application program can be generated, the application program corresponding to the identifier is executed at the moment, and at least an operation interface of the application program is displayed on a projection interface (or a display interface of the electronic device); if sensing that a certain mark is pressed for a long time, generating a second instruction for deleting the icon mark so as to execute the operation of deleting the application program corresponding to the mark, wherein at least the mark is deleted on the projection interface; or when the sensed touch operation is a sliding operation along the first direction on the projection interface, a third instruction for adjusting the display page may be generated, such as displaying a next page of the current page, or displaying the next page of the current page by clockwise rotating the current page by a preset angle along the first direction. Alternatively, the gesture operation may be a gesture operation in a space, and the gesture sensing module may also sense the gesture operation in the space and correspondingly perform the transformation of the projection direction or the content.
How to adjust the projection orientation or the projection content according to the embodiment of the present invention will be described in detail below. As shown in fig. 2, a flowchart illustrating a method for adjusting a projection orientation and/or projection content based on the operation gesture according to an embodiment of the present invention includes:
judging whether the operation gesture is a touch operation aiming at an application icon on a projection interface;
if yes, based on the touch operation, corresponding operation is executed on the application icon, and an operation result corresponding to the touch operation is displayed at the same time.
That is, when an application icon of an application program of the electronic device is displayed on the projection interface, the application program may be controlled based on a touch operation on the projection interface. And if the application icon is clicked, the execution of the application program is triggered, and at the moment, the application interface of the application program can be displayed on the projection interface. And deleting the application program if the application icon is pressed for a long time within the preset time, and deleting the application icon on the projection interface. The transition of the projection content can be performed by the above.
Further, in the embodiment of the present invention, when the operation result corresponding to the touch operation is displayed, the projection orientation may be adjusted according to a preset rule, for example, the projection module is rotated according to a preset angle to adjust to a new projection orientation, and at this time, the operation result may be displayed in the projection interface in the new projection orientation. By the configuration, user experience can be improved, the change of the current page of the user is prompted, and meanwhile, use interest can be increased. In addition, before the projection orientation is adjusted, the current projection interface can be saved and associated with the current projection orientation, so that when the projection orientation is adjusted, the projection interface corresponding to the projection interface can be displayed.
As shown in fig. 3, a schematic flowchart of a method for adjusting a projection orientation and/or projection content based on the operation gesture according to another embodiment of the present invention includes:
judging whether the operation gesture is a preset gesture or not;
if yes, the current projection content of the first interface is switched to the projection content of the second interface.
As described above, the gesture sensing module in the embodiment of the present invention may sense an operation gesture on the projection interface or on the space of the projection orientation, and the electronic device may adjust the projection orientation or the projection content based on the operation gesture.
For example, when the gesture sensing module senses that the operation gesture is a sliding operation in the first direction, the electronic device adjusts the display content on the current projection interface to the display content of the next page, that is, switches the projection content of the current first interface to the projection content of the second interface (the projection content of the next page). Or, when the gesture sensing module senses that the operation gesture is a sliding operation in the second direction, the electronic device adjusts the display content on the current projection interface to the display content of the previous page, that is, the projection content of the current first interface is switched to the projection content of the second interface (the projection content of the previous page). Wherein the first direction and the second direction are different directions, such as opposite directions. In the embodiment of the present invention, the projection module may encode the content of the page to be projected, may determine the current projection content based on the encoding, and may increase or decrease the encoding correspondingly when the sliding operation is sensed, so as to determine the projection content of the previous page or the next page.
Specifically, in the embodiment of the present invention, the electronic device may include a plurality of main operation interfaces, for example, three main operation interfaces, where the electronic device may encode the plurality of main operation interfaces to generate encoded identifiers corresponding to the operation interfaces, and an order of each encoded identifier corresponds to an order of the main operation interfaces. When a sliding gesture in a first direction is detected on the projection interface, projecting the operation interface of the next code identifier after the code identifier corresponding to the current projection content as new projection content; when the sliding gesture in the second direction is detected on the projection interface, the operation interface of the last code identifier before the code identifier corresponding to the current projection content is used as new projection content to be projected, so that the projection content of the projection interface is correspondingly adjusted.
In addition, when the received images are projected in the embodiment of the present invention, the received images may be encoded to generate encoded identifiers corresponding to the images, and an order of the encoded identifiers corresponds to an order of the images. When a sliding gesture in a first direction is detected on a projection interface, projecting an image of a next coding identifier after a coding identifier corresponding to an image of the current projection content as new projection content; when a sliding gesture in the second direction is detected on the projection interface, the image of the previous coding identifier before the coding identifier corresponding to the image of the current projection content is projected as new projection content, so that the corresponding adjustment of the projection content of the projection interface is realized.
Further, in the embodiment of the present invention, when the current projection content of the first interface is switched to the projection content of the second interface, the projection orientation may be adjusted according to a preset rule, for example, the projection module is rotated according to a preset angle to adjust to a new projection orientation, and at this time, the projection content of the second interface may be displayed in the projection interface in the new projection orientation. By the configuration, user experience can be improved, the change of the current page of the user is prompted, and meanwhile, use interest can be increased. In addition, before the projection orientation is adjusted, the current projection interface can be saved and associated with the current projection orientation, so that when the projection orientation is adjusted, the projection interface corresponding to the projection interface can be displayed.
In addition, in the embodiment of the invention, the gesture operation track can be displayed based on handwriting and touch operation of a user on the projection interface. In other words, the user can perform operations such as drawing and writing on the projection interface and display the results of the operations on the projection interface in real time.
In addition, as shown in fig. 4, a flowchart illustrating a method for adjusting a projection orientation and/or projection content based on the operation gesture according to another embodiment of the present invention is provided, where the method includes:
judging whether the position of the operation gesture is at the boundary of a projection interface;
if so, the projection orientation is adjusted based on the boundary.
In an embodiment of the present invention, the electronic device may determine a position where the gesture sensing module senses the operation gesture, for example, determine a current position of the gesture operation through an image obtained by the gesture sensing operation module, and adjust the projection orientation and the projection content according to a preset criterion when it is determined that the position of the operation gesture is at the boundary of the projection interface.
The projection interface in the embodiment of the invention can be matched with a screen interface of the electronic equipment, and if the projection interface can be constructed to be a quadrangle, the projection interface also has four boundaries, namely an upper boundary, a lower boundary, a left boundary and a right boundary, as with a display interface of the equipment. Alternatively, in other embodiments, the projection interface may be circular or other shapes. Regardless of the shape of the projection interface, the projection orientation may be controlled to be adjusted when the position of the operation gesture is determined to be on the boundary, or when the position of the operation gesture is maintained on the boundary for a preset time.
For example, in one embodiment, a user may perform a handwriting operation or a touch operation such as writing, drawing, and the like on the projection interface, and when the touch operation reaches any boundary of the projection interface, or reaches the any boundary and is maintained for a preset time, the projection orientation may be adjusted according to a preset criterion.
In this embodiment of the present invention, adjusting the projection orientation according to the preset criterion and based on the determined boundary may include:
determining a location of the boundary;
adjusting the current first projection orientation to a second projection orientation based on the direction corresponding to the position of the boundary;
and projecting the projection content according to the second projection direction.
When the projection interface is in a shape other than a quadrangle, the position of the boundary where the gesture operation is currently located may be determined to be one of the upper boundary, the lower boundary, the left boundary, or the right boundary. For example, the boundary position may be determined based on a coordinate system established in the projection interface, and the x-axis of the transverse coordinate axis and the y-axis of the longitudinal coordinate axis may be established with the center of the projection interface as the center of the coordinate system. Wherein the positive x-axis direction refers to the right boundary, the negative x-axis direction refers to the left boundary, the positive y-axis direction refers to the upper boundary, and the negative x-axis direction refers to the lower boundary. When an included angle between a connecting line between the boundary position and the center of the gesture operation and the positive direction of the x axis is within a preset angle, the boundary position of the gesture is a right boundary. And when the included angle between the connecting line between the boundary position and the center of the gesture operation and the positive direction of the y axis is within a preset angle, the boundary position of the gesture is an upper boundary. And when the included angle between the connecting line between the boundary position and the center of the gesture operation and the opposite direction of the x axis is within a preset angle, the boundary position of the gesture is a left boundary. And when the included angle between the connecting line between the boundary position and the center of the gesture operation and the reverse direction of the y axis is within a preset angle, the boundary position of the gesture is a lower boundary. The preset angle is less than 45 degrees.
Based on the above, the boundary position where the current gesture operation is clearly determined, and after the boundary position is determined, the projection orientation and the projection content may be further adjusted according to the preset criteria. In the embodiment of the invention, the projection orientation can be adjusted by rotating the corresponding boundary direction by a preset angle based on the determined boundary where the gesture operation is located.
For example, when the gesture operation is performed at the upper boundary position of the projection interface, or at the upper boundary position and is maintained for a preset time, the projection module may adjust the projection orientation thereof upward by a preset angle, such as 45 degrees, so as to form a new projection interface based on the new projection orientation. Or, when the gesture operation is performed at the lower boundary position of the projection interface, or at the lower boundary position and is maintained for the preset time, the projection module may adjust the projection orientation of the projection module downward by a preset angle, for example, 45 degrees, so as to form a new projection interface based on the new projection orientation. Or when the gesture operation is performed at the upper boundary position of the projection interface or at the upper boundary position and is kept for the preset time, the projection module can adjust the projection direction of the projection module upwards by a preset angle, such as 45 degrees, so as to form a new projection interface based on the new projection direction. Or, when the gesture operation is performed at the left boundary position of the projection interface, or at the left boundary position and is maintained for a preset time, the projection module may adjust the projection orientation thereof to the left by a preset angle, such as 90 degrees, so as to form a new projection interface based on the new projection orientation. When the gesture operation is performed at the right boundary position of the projection interface or at the right boundary position and is kept for the preset time, the projection module can adjust the projection direction of the projection module to the right by a preset angle, such as 90 degrees, so as to form a new projection interface based on the new projection direction. The preset angle in the embodiment of the present invention may be any angle greater than 0 degree and less than or equal to 90 degrees, and may specifically be configured correspondingly according to requirements.
Furthermore, after the projection direction of the head of the projection module is adjusted to a new projection direction, the projection content can be adjusted according to a preset criterion. Wherein, the current projection orientation can be used as a first projection orientation, the new projection orientation is used as a second projection orientation, and then projecting the projection content according to the second projection orientation comprises:
switching the first projection content of the first projection orientation to project according to the second projection orientation; or obtaining second projection content corresponding to the second projection orientation; projecting the second projection content according to the second projection orientation; wherein the second projection content corresponding to the second projection orientation is different from the first projection content corresponding to the first projection orientation.
When the projection orientation is adjusted, the projection content in the current first projection orientation can be displayed on the new second projection orientation, that is, the projection orientation is changed, and the projection content is not changed. For example, when a meeting is opened, the projection content can be adjusted to a suitable angle for the participants to watch in the above mode without moving the projector, and the method has the characteristic of convenience in operation.
In addition, when the electronic device performs the projection operation, preset projection content may be allocated to each projection orientation, and after the projection orientation is adjusted, the projection content corresponding to the new second projection orientation may be displayed on the projection interface, that is, as the projection orientation changes, the projection content also changes correspondingly. For example, the operation interface of the electronic device can be switched by the above configuration, which is equivalent to sliding the operation interface of the electronic device to realize the viewing of the previous page or the next page. Based on the configuration, the projection direction and the projection content can be automatically changed without manually operating the electronic equipment by a user, and the user experience is better.
In addition, in the embodiment of the present invention, adjusting the projection orientation according to the preset criterion may further include rotating the projection module at a constant speed according to a preset speed to change the projection interface at a constant speed, that is, to implement 360-degree constant rotation of the projection interface. Further, the electronic device can form the projection content obtained in advance into an image of 360 degrees, each angle corresponds to the preset projection content, and when the projection direction rotates to the corresponding angle, the image corresponding to the angle is displayed, so that the automatic expansion of the image is realized, and the effect of viewing agility is achieved.
Furthermore, the electronic device in the embodiment of the present invention may also be applied to the field of virtual display, and the electronic device may detect the first object, and adjust the projection orientation according to a preset angle when the position of the first object is located at the boundary of the current projection interface, and simultaneously adjust the projection content corresponding to the projection orientation. For example, the first object may be a small train, the content displayed on the projection interface includes a fire lane, when the first object is located at a position where the boundary of the projection interface is located on the fire lane, the projection orientation may be adjusted, for example, rotated at a constant speed according to the above configuration, and the first object also travels according to a preset route, which may be matched with the adjustment of the projection orientation. For example, the travel line of the first object may be a travel line of a fire lane, so that a viewing effect that the first object always travels on the fire lane in the projection interface can be obtained, and a combination of virtual and real is realized.
Through the configuration, on one hand, the projection of the electronic equipment can be realized, and meanwhile, the change of the projection content can be executed based on the operation gesture on the projected projection interface, or the projection direction can be changed, or the projection direction or the projection content can be changed at the same time; on the other hand, through gesture operation, the projection content can be switched without operating the electronic equipment, and better user experience is achieved.

And if the application icon is clicked, the execution of the application program is triggered, and at the moment, the application interface of the application program can be displayed on the projection interface. And deleting the application program if the application icon is pressed for a long time within the preset time, and deleting the application icon on the projection interface. The transition of the projection content can be performed by the above.
Further, the projection module 2 may also adjust the projection orientation according to a preset rule when displaying the operation result corresponding to the touch operation, for example, rotate the projection module according to a preset angle to adjust to a new projection orientation, and at this time, may display the operation result to the projection interface in the new projection orientation. By the configuration, user experience can be improved, the change of the current page of the user is prompted, and meanwhile, use interest can be increased. In addition, before the projection module 2 adjusts the projection orientation, the current projection interface can be saved and associated with the current projection orientation, so that when the projection orientation is adjusted, the projection interface corresponding to the projection interface can be displayed.
In another embodiment of the present invention, the adjusting the projection orientation and/or the projection content by the projection module 2 based on the operation gesture may include:
judging whether the operation gesture is a preset gesture or not;
if yes, the current projection content of the first interface is switched to the projection content of the second interface.
As described above, the gesture sensing module in the embodiment of the present invention may sense an operation gesture on the projection interface or on the space of the projection orientation, and the electronic device may adjust the projection orientation or the projection content based on the operation gesture.
For example, when the gesture sensing module senses that the operation gesture is a sliding operation in the first direction, the projection module 2 may adjust the display content on the current projection interface to the display content of the next page, that is, switch the projection content of the current first interface to the projection content of the second interface (the projection content of the next page). Or, when the gesture sensing module senses that the operation gesture is a sliding operation in the second direction, the electronic device adjusts the display content on the current projection interface to the display content of the previous page, that is, the projection content of the current first interface is switched to the projection content of the second interface (the projection content of the previous page). Wherein the first direction and the second direction are different directions, such as opposite directions. In the embodiment of the present invention, the projection module may encode the content of the page to be projected, may determine the current projection content based on the encoding, and may increase or decrease the encoding correspondingly when the sliding operation is sensed, so as to determine the projection content of the previous page or the next page.
Specifically, the electronic device in the embodiment of the present invention may include a plurality of main operation interfaces, for example, 3 operation interfaces, wherein the projection module 2 may encode the plurality of main operation interfaces to generate encoded identifiers corresponding to the operation interfaces, and the sequence of the encoded identifiers corresponds to the sequence of the main operation interfaces. When a sliding gesture in a first direction is detected on the projection interface, the projection module 2 may project an operation interface of a next code identifier after the code identifier corresponding to the current projection content as new projection content; when the sliding gesture in the second direction is detected on the projection interface, the operation interface of the last code identifier before the code identifier corresponding to the current projection content is used as new projection content to be projected, so that the projection content of the projection interface is correspondingly adjusted.
In addition, when the projection module 2 projects the received images, the received images may be encoded to generate encoded identifiers corresponding to the images, and an order of the encoded identifiers corresponds to an order of the images. When a sliding gesture in a first direction is detected on a projection interface, projecting an image of a next coding identifier after a coding identifier corresponding to an image of the current projection content as new projection content; when a sliding gesture in the second direction is detected on the projection interface, the image of the previous coding identifier before the coding identifier corresponding to the image of the current projection content is projected as new projection content, so that the corresponding adjustment of the projection content of the projection interface is realized.
Further, the projection module 2 according to the embodiment of the present invention may also adjust the projection orientation according to a preset rule when the current projection content of the first interface is switched to the projection content of the second interface, for example, rotate the projection module according to a preset angle to adjust to a new projection orientation, and at this time, display the projection content of the second interface to the projection interface in the new projection orientation. By the configuration, user experience can be improved, the change of the current page of the user is prompted, and meanwhile, use interest can be increased. In addition, before the projection orientation is adjusted, the current projection interface can be saved and associated with the current projection orientation, so that when the projection orientation is adjusted, the projection interface corresponding to the projection interface can be displayed.
In addition, in the embodiment of the invention, the gesture operation track can be displayed based on handwriting and touch operation of a user on the projection interface. In other words, the user can perform operations such as drawing and writing on the projection interface and display the results of the operations on the projection interface in real time.
In addition, as another embodiment of the present invention, the adjusting the projection orientation and/or the projection content by the projection module 2 based on the operation gesture may further include:
judging whether the position of the operation gesture is at the boundary of a projection interface;
if so, the projection orientation is adjusted based on the boundary.
In the embodiment of the present invention, the projection module 2 may determine the position of the operation gesture sensed by the gesture sensing module, for example, determine the current position of the gesture operation through the image acquired by the gesture sensing operation module, and adjust the projection direction and the projection content according to a preset criterion when it is determined that the position of the operation gesture is at the boundary of the projection interface.
The projection interface in the embodiment of the invention can be matched with a screen interface of the electronic equipment, and if the projection interface can be constructed to be a quadrangle, the projection interface also has four boundaries, namely an upper boundary, a lower boundary, a left boundary and a right boundary, as with a display interface of the equipment. Alternatively, in other embodiments, the projection interface may be circular or other shapes. Regardless of the shape of the projection interface, the projection orientation may be controlled to be adjusted when the position of the operation gesture is determined to be on the boundary, or when the position of the operation gesture is maintained on the boundary for a preset time.
In an embodiment, a user may perform handwriting or touch operations such as writing and drawing on the projection interface, and when the projection module 2 determines that the touch operation reaches any boundary of the projection interface, or reaches the any boundary and keeps a preset time, the projection direction may be adjusted according to a preset criterion.
In this embodiment of the present invention, adjusting the projection orientation according to the preset criterion and based on the determined boundary may include:
determining a location of the boundary;
adjusting the current first projection orientation to a second projection orientation based on the direction corresponding to the position of the boundary;
and projecting the projection content according to the second projection direction.
The position of the boundary where the gesture operation is located, such as the upper boundary, the lower boundary, the left boundary, or the right boundary, is determined through the image acquired by the sensing module 3, and when the projection interface is in a shape other than a quadrilateral, the position of the boundary where the gesture operation is currently located may be determined as one of the upper boundary, the lower boundary, the left boundary, or the right boundary. For example, the boundary position may be determined based on a coordinate system established in the projection interface, and the x-axis of the transverse coordinate axis and the y-axis of the longitudinal coordinate axis may be established with the center of the projection interface as the center of the coordinate system. Wherein the positive x-axis direction refers to the right boundary, the negative x-axis direction refers to the left boundary, the positive y-axis direction refers to the upper boundary, and the negative x-axis direction refers to the lower boundary. When an included angle between a connecting line between the boundary position and the center of the gesture operation and the positive direction of the x axis is within a preset angle, the boundary position of the gesture is a right boundary. And when the included angle between the connecting line between the boundary position and the center of the gesture operation and the positive direction of the y axis is within a preset angle, the boundary position of the gesture is an upper boundary. And when the included angle between the connecting line between the boundary position and the center of the gesture operation and the opposite direction of the x axis is within a preset angle, the boundary position of the gesture is a left boundary. And when the included angle between the connecting line between the boundary position and the center of the gesture operation and the reverse direction of the y axis is within a preset angle, the boundary position of the gesture is a lower boundary. The preset angle is less than 45 degrees.
Based on the above, the boundary position where the current gesture operation is clearly determined, and after the boundary position is determined, the projection module 2 may further adjust the projection direction and the projection content according to the preset criterion. In the embodiment of the invention, the projection orientation can be adjusted by rotating the corresponding boundary direction by a preset angle based on the determined boundary where the gesture operation is located.
For example, when the gesture operation is performed at the upper boundary position of the projection interface, or at the upper boundary position and is maintained for a preset time, the projection module 2 may adjust the projection orientation thereof by a preset angle upward, such as 45 degrees, so as to form a new projection interface based on the new projection orientation. Alternatively, when the gesture operation is performed at the lower boundary position of the projection interface, or at the lower boundary position and is maintained for the preset time, the projection module 2 may adjust the projection orientation thereof downward by a preset angle, for example, 45 degrees, so as to form a new projection interface based on the new projection orientation. Alternatively, when the gesture operation is performed at the upper boundary position of the projection interface, or at the upper boundary position and is maintained for the preset time, the projection module 2 may adjust the projection orientation thereof by a preset angle, such as 45 degrees, upwards to form a new projection interface based on the new projection orientation. Alternatively, when the gesture operation is performed at the left boundary position of the projection interface, or at the left boundary position and is maintained for a preset time, the projection module 2 may adjust the projection orientation thereof to the left by a preset angle, such as 90 degrees, so as to form a new projection interface based on the new projection orientation. When the gesture operation is performed at the right boundary position of the projection interface or at the right boundary position and is kept for the preset time, the projection module can adjust the projection direction of the projection module to the right by a preset angle, such as 90 degrees, so as to form a new projection interface based on the new projection direction. The preset angle in the embodiment of the present invention may be any angle greater than 0 degree and less than or equal to 90 degrees, and may specifically be configured correspondingly according to requirements.
Further, after the head projection direction of the projection module 2 is adjusted to a new projection direction, the projection content can be adjusted according to a preset criterion. Wherein, the current projection orientation can be used as a first projection orientation, the new projection orientation is used as a second projection orientation, and then projecting the projection content according to the second projection orientation comprises:
switching the first projection content of the first projection orientation to project according to the second projection orientation; or obtaining second projection content corresponding to the second projection orientation; projecting the second projection content according to the second projection orientation; wherein the second projection content corresponding to the second projection orientation is different from the first projection content corresponding to the first projection orientation.
When the projection orientation is adjusted, the projection content in the current first projection orientation can be displayed on the new second projection orientation, that is, the projection orientation is changed, and the projection content is not changed. For example, when a meeting is opened, the projection content can be adjusted to a suitable angle for the participants to watch in the above mode without moving the projector, and the method has the characteristic of convenience in operation.
In addition, when the projection module 2 performs the projection operation, it may allocate a preset projection content to each projection orientation, and after the projection orientation is adjusted, it may also display the projection content corresponding to the new second projection orientation on the projection interface, that is, along with the change of the projection orientation, the projection content is also changed correspondingly. For example, the operation interface of the electronic device can be switched by the above configuration, which is equivalent to sliding the operation interface of the electronic device to realize the viewing of the previous page or the next page. Based on the configuration, the projection direction and the projection content can be automatically changed without manually operating the electronic equipment by a user, and the user experience is better.
In addition, in the embodiment of the present invention, adjusting the projection orientation according to the preset criterion may further include rotating the projection module at a constant speed according to a preset speed to change the projection interface at a constant speed, that is, to implement 360-degree constant rotation of the projection interface. Further, the electronic device can form the projection content obtained in advance into an image of 360 degrees, each angle corresponds to the preset projection content, and when the projection direction rotates to the corresponding angle, the image corresponding to the angle is displayed, so that the automatic expansion of the image is realized, and the effect of viewing agility is achieved.
Furthermore, the electronic device in the embodiment of the present invention may also be applied to the field of virtual display, and the electronic device may detect the first object, and adjust the projection orientation according to a preset angle when the position of the first object is located at the boundary of the current projection interface, and simultaneously adjust the projection content corresponding to the projection orientation. For example, the first object may be a small train, the content displayed on the projection interface includes a fire lane, when the first object is located at a position where the boundary of the projection interface is located on the fire lane, the projection orientation may be adjusted, for example, rotated at a constant speed according to the above configuration, and the first object also travels according to a preset route, which may be matched with the adjustment of the projection orientation. For example, the travel line of the first object may be a travel line of a fire lane, so that a viewing effect that the first object always travels on the fire lane in the projection interface can be obtained, and a combination of virtual and real is realized.
Through the configuration, on one hand, the projection of the electronic equipment can be realized, and meanwhile, the change of the projection content can be executed based on the operation gesture on the projected projection interface, or the projection direction can be changed, or the projection direction or the projection content can be changed at the same time; on the other hand, through gesture operation, the projection content can be switched without operating the electronic equipment, and better user experience is achieved.
