Embodiment one:
referring to fig. 1-3, fig. 1 is a flowchart of a method for controlling a content output position of a mobile terminal in a VR headset according to an embodiment of the present invention, fig. 2 is a schematic diagram of a mobile terminal being worn in a receiving means of the VR headset according to an embodiment of the present invention, and fig. 3 is a schematic diagram of a probe mounting position according to an embodiment of the present invention, in which a probe is disposed in a receiving box of the VR headset, and the position of the probe is associated with a center line of an optical system of the VR headset. When the smart phone is placed in the accommodating device in the VR headset, the probe can be in contact with the touch screen of the smart phone, so that the mobile terminal can recognize the position information of the probe. In practical application, the mobile terminal may be a smart phone, a tablet computer, MP4, MP5, etc., and the VR headset may be a VR helmet, etc.
As shown in fig. 1, the method includes:
in step S110, the position of the probe on the touch screen of the mobile terminal is detected.
In order to accurately detect the position information of the probe on the touch screen of the mobile terminal, in one embodiment of the invention, a point at the lower left corner of the touch screen of the mobile terminal is taken as an origin, the horizontal direction in which the bottom edge of the touch screen of the mobile terminal is positioned is taken as an x-axis, the vertical direction in which the left side of the touch screen of the mobile terminal is positioned is taken as a y-axis, a two-dimensional rectangular coordinate system is established, and when the mobile terminal is placed in a containing box of VR headset, the x-axis coordinate of the probe in the two-dimensional coordinate system is identified; and detecting the position of the probe on the touch screen of the mobile terminal according to the identified x-axis coordinate of the probe.
In one embodiment of the present invention, the number of probes may be one or more. The following are examples of the method of setting the number of probes to one, two and three:
when the number of probes is one, the probes are disposed at positions where the center line of the optical system of the VR headset is located.
And (II) when the number of the probes is two, as shown in fig. 3, two probes are arranged in the accommodating device of the VR headset according to a preset distance (for example, 80 mm), and the position centers of the two probes are coincident with the central line of the optical system of the VR headset.
And (III) when the number of the probes is three, setting a first probe at the center of a containing device of the VR headset (the center of an optical system corresponding to the VR headset), and setting the other two probes with the first probe as the center according to a preset distance (for example, 80 mm).
In summary, when the number of probes is an odd number, a first probe is arranged in the accommodating device of the VR headset corresponding to the center of the optical system of the VR headset, and the rest probes are symmetrically arranged with the first probe as the center according to a preset distance; when the number of the probes is even, the probes are symmetrically arranged in the accommodating device of the VR head-mounted device by taking the central line of the optical system of the VR head-mounted device as the center according to a preset distance; the purpose that the position deviation between the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset can be calculated only by identifying the position coordinates of the probe is achieved. In practical applications, the number of probes may be set according to practical situations.
In step S120, a positional deviation between a center line of the touch screen of the mobile terminal and a center line of an optical system of the VR headset is calculated according to a position of the probe on the touch screen of the mobile terminal.
In order to accurately calculate the position deviation between the center line of the touch screen of the mobile terminal and the center line of the optical system of the VR headset, the position deviation can be eliminated better. The following list the probe for one, two and three position deviation calculation method:
when the number of probes is one, a method for calculating a positional deviation between a center line of a touch panel of a mobile terminal and a center line of an optical system of a VR headset.
Setting a first preset value N (55 mm), wherein the first preset value N is a position parameter when the central line of a touch screen of the mobile terminal is overlapped with the central line of an optical system of the VR headset when the mobile terminal is installed at the optimal position in the VR headset. Note that N is the position where the center line of the optical system of the pre-stored VR headset is located. The coordinate of the identified probe is X 0 The calculation formula of the position deviation of the screen center line of the mobile terminal and the center line of the VR headset optical system is Deltax=N-X 0 ；
And (II) a position deviation calculating method of the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR head-mounted device when the number of the probes is two.
According to the formula Δx= (x 1 +x 2 -a)/2 calculating a positional deviation of a center line of a touch screen of the mobile terminal from a center line of an optical system of the VR headset, wherein x1 and x2 are x-axis coordinates of two probes, and a is a length of the touch screen of the mobile terminal;
and (III) in the case that the number of the probes is three, a position deviation calculating method of the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset.
Detecting the position coordinate of the intermediate probe as X 0 The position coordinates of the other two probes are x1 and x2 respectively, a first position deviation is calculated according to a pre-stored first preset value N, and a calculation formula of the first position deviation is deltax 1 ＝N-X 0 The method comprises the steps of carrying out a first treatment on the surface of the Calculating a second position deviation according to the length a of the touch screen of the mobile terminal, wherein a calculation formula of the second position deviation is deltax 2 ＝(x 1 +x 2 -a)/2. And calculating the position deviation of the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset according to the first position deviation and the second position deviation. The calculation formula is as follows
After calculating the position deviation between the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset through any deviation calculation method, if Deltax is positive, judging that the position where the mobile terminal is placed is deviated from the right side of the VR headset, and controlling the output position of VR content to move leftwards or sending a prompt for leftwards moving the mobile terminal to a user; if Deltax is negative, the position where the mobile terminal is placed is judged to be deviated from the left side of the VR headset, the output position of VR content is controlled to move rightwards or the mobile terminal is prompted to rightwards to a user, so that the effect that the output position of the VR content of the mobile terminal in an optical system of the VR headset can be automatically adjusted, the user can be instructed to manually adjust in a voice or text prompt information mode, the output position of the VR content provided by the mobile terminal in the VR headset is enabled to be optimal, and the visual experience of the user is improved.
In step S130, the output position of the VR content provided by the mobile terminal in the optical system of the VR headset is controlled according to the position deviation.
Because the mobile terminal automatically adjusts the output position of the VR content to have a certain range, when the deviation between the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset exceeds the range, the mobile terminal cannot automatically adjust the output position of the VR content, and an information prompt mechanism is established to solve the problem.
In one embodiment of the present invention, after calculating the position deviation between the center line of the touch screen of the mobile terminal and the center line of the optical system of the VR headset, the deviation is compared with a preset value (for example, 1 mm), if the deviation is greater than the preset value, it is indicated that the software installed on the mobile terminal cannot adjust the output position of the VR content to optimize the user's visual experience, and in this case, the mobile terminal sends the user with a voice or text prompt message, which is the direction and distance of the mobile terminal that needs to be moved when the position deviation is eliminated. And if the deviation is smaller than the preset value, automatically adjusting the output position of the VR content on the touch screen of the mobile terminal. It should be further described that, when the user performs manual adjustment according to the prompt information, the mobile terminal detects the position information of the probe in real time and calculates the position deviation between the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset, and continuously compares the position deviation with a preset value (for example, 1 mm), if the deviation is still greater than the preset value, the mobile terminal continuously sends the prompt information to the user; if the deviation is smaller than a preset value after manual adjustment by the user, the mobile terminal automatically adjusts the output position of the VR content on the touch screen of the mobile terminal. That is, if the user does not directly adjust the mobile terminal to the optimal wearing position, but the position deviation is within the automatic adjustment range of the mobile terminal after the user manually adjusts, the mobile terminal will automatically adjust the output position of the VR content on the touch screen of the mobile terminal, so that the visual experience of the user is optimal.
In summary, according to the technical scheme provided by the invention, the probe is arranged in the accommodating device of the VR headset, and the position of the probe is associated with the central line of the optical system of the VR headset; when the mobile terminal is placed in the accommodating device of the VR headset, the probe is contacted with the touch screen of the mobile terminal, so that the mobile terminal can accurately acquire the position information of the probe; the mobile terminal is utilized to detect the position information of the probe on the touch screen of the mobile terminal, so that the purpose that the position deviation between the central line of the touch screen of the mobile terminal and the central line of the optical system of the VR headset can be calculated as long as the position information of the probe is obtained is achieved; and controlling the output position of the VR content provided by the mobile terminal in the optical system of the VR headset according to the position deviation. By adopting the technical scheme, the output position of the VR content provided by the mobile terminal in the VR head-mounted device is optimal, and the visual experience of a user is improved.
In order to make the scheme clear and clear, a specific example will be explained below. Taking two probes arranged in a box of a VR headset as an example, a 5.0 inch mobile terminal with 1080p screen resolution is placed in the VR headset, the length and width of the mobile terminal are 110 millimeters (mm) and 62mm, respectively, fig. 4 is a schematic diagram of two-dimensional coordinates established by a touch screen of the mobile terminal according to one embodiment of the invention, such asAs shown in fig. 4, a two-dimensional coordinate system is established for the touch screen of the entire mobile terminal by taking the point of the lower left corner of the touch screen of the mobile terminal as the origin, and the X and Y axes are equally divided into 100 levels, each level representing the value obtained by dividing the length and width dimensions of the mobile phone by 100, that is, the minimum resolution level on the X axis is 1.1mm and the minimum resolution level on the Y axis is 0.62mm; when the mobile terminal is put into the accommodating box of the VR headset, the software installed on the mobile terminal can respectively detect the coordinates of the two probes on the X axis, which are respectively X 1 ，x 2 (as shown in fig. 5). After identifying the X-axis coordinates of the two probes, the formula is: Δx= (x 1 +x 2 -110)/2 calculate the position deviation; after the mobile terminal software calculates the DeltaX, if DeltaX is positive, judging that the position where the mobile terminal is placed is deviated from the right side of VR headset equipment, and controlling the output position of VR content to move leftwards or sending a prompt for moving the mobile terminal leftwards to a user; if Deltax is negative, judging that the position where the mobile terminal is placed is deviated from the left side of the VR headset, controlling the output position of the VR content to move rightwards or prompting a user to move the mobile terminal rightwards, so that the central line of the touch screen of the mobile terminal corresponds to the central line of the optical system of the VR headset, the output position of the VR content provided by the mobile terminal in the VR headset is optimal, and the visual experience of the user is improved.
