Referring to fig. 1, fig. 1 is a schematic view of a viewing angle field of a user of an MR system, in which a gray background part is a viewing angle field range of the user, and in the viewing angle field range of the user, after entering a main interface, the user wears smart glasses to move in a real space, the main interface changes along with the change of the viewing angle of the user, and when the spatial position of the main interface remains unchanged, the main interface position is easily lost in the viewing angle of the user.
Accordingly, the present application provides an object display method, referring to fig. 2, where fig. 2 is a flowchart of the object display method, and mainly includes the following steps:
step S10, displaying at least one target object within the target space range; the target space range is at least one preset space range in the space range of the field angle of the user.
In the step, at least one space range is constructed in the space of the user field angle by using the user field angle of the glasses equipment as a target space range, and at least one target object is displayed in the target space range; for a target spatial range, having a certain spatial coordinate range, a target object may refer to all objects that need to be displayed in space, such as interfaces, icons, etc., and a target object may be a two-dimensional or three-dimensional object.
In one embodiment, the target object may be a partial image or an entire image in the display object; the target space range can be a plurality of independent spaces or a single space; the reverse movement includes at least a direction movement with a component opposite to the overrun direction.
Specifically, taking a main interface of a two-dimensional MR system as an example, referring to fig. 3, fig. 3 is a schematic diagram of a target object, where the target object may be an entire image of the main interface or may be an image of a certain portion of the main interface (e.g., a dashed frame portion in the drawing), a target space range may be a plurality of independent spaces or a single space, and a plurality of independent spaces may be constructed in the space. For the reverse movement, as shown in fig. 4, fig. 4 is a schematic diagram of the reverse movement, which at least includes the direction movement with the component opposite to the over direction, that is, the included angle with the over direction of the original movement is greater than plus or minus 90 °, so that at least the target object has the opposite direction movement to avoid further exceeding the target space range.
As an application example, after a user starts entry into the HOME interface of the MR system, or after the user presses a HOME page (HOME) key to swap out the HOME interface, for example, the HOME interface is displayed at a specified position within the user's field angle range. As shown in fig. 5, fig. 5 is a schematic diagram of a display position of a main interface in an initial state, the main interface is firstly displayed, and the main interface is placed at the center of a field angle of a user; the distance between the main interface and the user is then set. Initially, the main interface may be displayed at the center of the field angle range of the user, and meanwhile, the normal vector of the main interface is set to point to the user position, and the distance between the main interface and the user is set to be 2.3 meters.
Step S20, detecting the real-time position of the target object during the display process.
In this step, by detecting the real-time position of the display target object in real time during the movement, it is determined whether or not the predetermined display range is exceeded. When the intelligent glasses move, if the user wears the intelligent glasses to move in a real space, the main interface changes along with the change of the visual angle of the user, if the user wears the intelligent glasses to rotate the head, whether the position of the detection point exceeds the coverage range corresponding to the detection area or not is judged, and if the position of the detection point exceeds the coverage range, the adjustment processing of the next step is executed.
In one embodiment, for the method of detection, a reference point may be selected on the target object by whether the reference point is outside a predetermined display range.
For example, taking the main interface as an example, a detection point followed by the main interface may be selected on the main interface, then a detection area followed by the main interface is selected as a display area within a user field angle range, and the main interface is controlled to follow within a certain range by selecting the detection point and the detection area and detecting the detection point.
In one scheme, a plurality of reference points of the main interface can be selected on the main interface, and then the reference points are set as detection points followed by the main interface; the reference point may be set as the center point of the main interface or as four edge vertices of the main interface. In another scheme, a coverage area with a specific shape can be selected in the middle of the user field angle range according to the shape size of the main interface, and the coverage area is set as a detection area followed by the main interface; the coverage area of the specific shape may be set as a rectangular area in the middle within the user field angle range; in addition, the coverage area may be set according to actual requirements, or may be set to have other irregular shapes.
Referring to fig. 6, fig. 6 is a diagram showing an example of a main interface, assuming that the center point of the main interface is selected as the detection point O, and a rectangular ABCD is selected as the detection area within the field angle range of the user.
Referring to fig. 7, fig. 7 is another exemplary illustration of the main interface display, assuming that four edge vertices of the main interface are selected as the detecting points M, N, J, K, and a rectangular ABCD is selected as the detecting area within the field angle range of the user.
And step S30, when the target object exceeds the target space range, moving the target object reversely to display the target object in the corresponding target space range.
In the step, through judgment of the detection points, when the detection points exceed the coverage range, the main interface moves towards the direction of entering the detection area until the detection points enter the coverage range, so that the main interface is limited in a certain range, and the user is prevented from losing the position of the main interface.
Several embodiments of the technical solution of the present application are explained below with reference to the drawings.
Taking the central point of the main interface as the detection point O and the rectangle ABCD as the detection area as an example, referring to fig. 8, fig. 8 is a flowchart of the main interface following of an embodiment, which includes the following steps:
s801, detecting head 3DoF movement of the user;
s802, judging whether the detection point O exceeds the range of the rectangle ABCD; if yes, executing s803, otherwise executing s 805;
s803, the main interface moves to the direction of the access rectangle ABCD;
s804, judging whether the detection point O enters the rectangle ABCD, if so, executing s805, otherwise, returning to s 803;
s805, the home interface stops following the move.
In the above moving process, referring to fig. 9, fig. 9 is a schematic diagram of the detection point not exceeding the detection area, and the detection point O follows the left side AD of the rectangular ABCD and does not exceed the coverage of the rectangular ABCD, which is also the range in which the user can focus. Referring to fig. 10, fig. 10 is a schematic diagram of the detection point exceeding detection area, where the detection point O follows the left side AD of the rectangle ABCD and exceeds the coverage of the rectangle ABCD, and at this time, the control main interface moves toward the entering rectangle ABCD until the detection point O enters the coverage of the rectangle ABCD.
The technical scheme of the application can be applied to an MR system with 6DOF degrees of freedom, when the head of a user moves by 3DoF, the main interface moves and displays along with the user, and the focusing state of the main interface can be continuously kept after the user calls the main interface. Meanwhile, the frequent movement of the main interface when the head of the user slightly shakes is avoided.
In an embodiment, as shown in fig. 11, fig. 11 is a schematic diagram of opening a new application window, after adjusting the display position of the main interface, and after a user opens a new application window on the main interface, closing the display of the main interface, and displaying the application window at the center position of the current field angle of the user, so that the user can quickly focus on the new application window.

and the adjusting module 30 is configured to, when the target object exceeds the target space range, move the target object in a reverse direction, so that the target object is displayed in the corresponding target space range.
