The pressure detecting assembly 12 includes a housing 121 and a plurality of pressure detecting units 122, and the plurality of pressure detecting units 122 may be disposed outside the housing 121. For example, the plurality of pressure detecting units 122 may also be embedded on the side wall of the housing 121, and the sensing surface of the pressure detecting unit faces the outside of the housing. Wherein, a plurality of pressure detection unit 122 set up in different position, the response face of arbitrary pressure detection unit 122 is towards the outside of casing, like this, in the in-process that the user experienced wear display device, the position of interactive equipment changes along with user's gesture, when the interactive equipment takes place to remove, the interactive equipment takes place relative movement with the ambient air, in the moving direction of interactive equipment, the air produces pressure for interactive equipment, based on this, can respond to the change of the air pressure of different directions around the interactive equipment according to a plurality of pressure detection unit on the interactive equipment, with the moving direction of confirming interactive equipment according to the change of a plurality of pressure detection unit's pressure signal, and then can generate the motion trail of interactive equipment.
Here, the sensing surface of the pressure detection unit is an action surface for sensing pressure. The pressure detecting unit 122 may be a pressure sensor. Optionally, the pressure sensor is a relatively high sensitivity pressure sensor.
In this embodiment, the pressure detection unit may be provided at different positions of the housing according to the structure of the housing. The following examples are given by way of illustration.
In one embodiment, as shown in fig. 1, the housing 121 is a ball shape, and the plurality of pressure detecting units 122 are distributed along the center of the ball of the housing 121 in a central symmetry manner. For example, as shown in fig. 1, the pressure detecting assembly 12 may be provided at an upper end of the apparatus body 11. The pressure detecting assembly 12 includes a housing 121 and a plurality of pressure detecting units 122, the housing 121 may be spherical, and the plurality of pressure detecting units 122 may be disposed outside the spherical housing 121. For example, the plurality of pressure detecting units 122 may also be embedded on the side wall of the housing 121, and the sensing surface of the pressure detecting unit faces the outside of the housing. The plurality of pressure detection units 122 are disposed in different orientations, and a sensing surface of any one of the pressure detection units 122 faces the outside of the housing.
In one embodiment, the housing is a polyhedron and the plurality of pressure sensing cells are located on different sides of the housing. Illustratively, the casing of the interaction device is a cuboid, and at least one pressure detection unit is arranged on each side surface of the casing. Illustratively, the housing of the interaction device is a regular hexahedron, the interaction device includes six pressure detection units, and the six pressure detection units are respectively disposed on six side surfaces of the housing.
In this embodiment, the pressure detection assembly may include a plurality of pressure detection units, the number of the pressure detection units may be set according to practical experience, and the greater the number of the pressure detection units, the higher the detection accuracy of the pressure detection assembly. For example, 4 pressure detection cells, 6 pressure detection cells, or 8 pressure detection cells. The following examples are given by way of illustration.
In an alternative embodiment, the pressure detecting assembly 12 includes four pressure detecting units, including a first pressure detecting unit, a second pressure detecting unit, a third pressure detecting unit and a fourth pressure detecting unit; the first pressure detection unit and the second pressure detection unit are arranged along a first direction, and the sensing directions of the first pressure detection unit and the second pressure detection unit are opposite; the third pressure detection unit and the fourth pressure detection unit are arranged along a second direction, and the sensing directions of the third pressure detection unit and the fourth pressure detection unit are opposite; the first direction is different from the second direction.
In this embodiment, taking the case of the interactive device as a ball as an example, the pressure detection assembly 12 includes a case and four pressure detection units. A two-dimensional coordinate system is established by taking the spherical center of the shell as an origin, wherein the first direction is the X direction, and the second direction is the Y direction. The first pressure detection unit and the second pressure detection unit are arranged along a first direction, and the first pressure detection unit and the second pressure detection unit are opposite in direction. The third pressure detection unit and the fourth pressure detection unit are arranged along the second direction, and the directions of the third pressure detection unit and the fourth pressure detection unit are opposite. That is to say, when the interactive device is placed vertically, the first pressure detection unit and the second pressure detection unit are respectively arranged at the left side and the right side of the shell, and the third pressure detection unit and the fourth pressure detection unit are respectively arranged at the front side and the rear side of the shell. Therefore, when the interactive device moves in the process that the user uses the interactive device, the interactive device moves relative to the ambient air, pressure is generated on the interactive device by the air in the moving direction of the interactive device, based on the pressure, the moving direction of the interactive device is determined according to the change of the pressure signals of the pressure detection units on the interactive device, and then the motion track of the interactive device can be generated according to the moving direction of the interactive device.
For example, when the interactive device moves to the left, the pressure value of the pressure signal of the first pressure detection unit increases, while the pressure values of the pressure signals of the other pressure detection units are substantially unchanged in magnitude, and at this time, according to the setting position of the first pressure detection unit, it can be determined that the interactive device moves to the left. Then, according to the moving direction of the interactive device at each moment, the motion trail of the interactive device can be generated.
For example, when the interactive device moves to the left front, the pressure values of the pressure signals of the first pressure detection unit located on the left side and the third pressure detection unit located on the front side increase, while the magnitude of the pressure values of the pressure signals of the other pressure detection units is basically unchanged, and at this time, according to the setting positions of the first pressure detection unit and the third pressure detection unit, it can be determined that the interactive device moves to the left front. Then, according to the moving direction of the interactive device at each moment, the motion trail of the interactive device can be generated.
In another alternative embodiment, as shown in fig. 1 and 2, the pressure detecting assembly 12 includes six pressure detecting units including a first pressure detecting unit 122a, a second pressure detecting unit 122b, a third pressure detecting unit 122c, a fourth pressure detecting unit 122d, a fifth pressure detecting unit 122e, and a sixth pressure detecting unit 122 f; the first pressure detecting unit 122a and the second pressure detecting unit 122b are arranged along a first direction, and sensing directions of the first pressure detecting unit 122a and the second pressure detecting unit 122b are opposite; the third pressure detecting unit 122c and the fourth pressure detecting unit 122d are disposed along the second direction, and sensing directions of the third pressure detecting unit 122c and the fourth pressure detecting unit 122d are opposite; the fifth pressure detecting unit 122e and the sixth pressure detecting unit 122f are arranged along a third direction, and the sensing directions of the fifth pressure detecting unit 122e and the sixth pressure detecting unit 122f are opposite; the first direction, the second direction and the third direction are vertical to each other.
In this embodiment, continuing to take the case of the interactive device as a ball-type example, as shown in fig. 1 and 2, the pressure detection assembly 12 includes a case 121 and six pressure detection units. A three-dimensional coordinate system is established with the center of the sphere of the housing 121 as the origin, the first direction being the X direction, the second direction being the Y direction, and the third direction being the Z direction. The first and second pressure detecting units 122a and 122b are disposed in a first direction, and the first and second pressure detecting units 122a and 122b are oriented oppositely. The third and fourth pressure detecting units 122c and 122d are disposed in the second direction, and the third and fourth pressure detecting units 122c and 122d are oriented in opposite directions. The fifth and sixth pressure detecting units 122e and 122f are disposed in the second direction, and the fifth and sixth pressure detecting units 122e and 122f are oriented oppositely. That is, when the interactive apparatus is vertically placed, the first pressure detecting unit 122a and the second pressure detecting unit 122b are respectively disposed at left and right sides of the housing 121, the third pressure detecting unit 122c and the fourth pressure detecting unit 122d are respectively disposed at front and rear sides of the housing 121, and the fifth pressure detecting unit 122e and the sixth pressure detecting unit 122f are respectively disposed at upper and lower sides of the housing 121. Therefore, when the interactive equipment moves in the process of using the interactive equipment by a user, the interactive equipment moves relative to the ambient air, the air generates pressure for the interactive equipment in the moving direction of the interactive equipment, the moving direction of the interactive equipment is determined according to the change of pressure signals of a plurality of pressure detection units on the interactive equipment based on the pressure, and then the motion track of the interactive equipment can be generated according to the moving direction of the interactive equipment.
For example, when the interactive device moves to the right, the pressure value of the pressure signal of the second pressure detecting unit 122b increases, while the magnitudes of the pressure values of the pressure signals of the other pressure detecting units are substantially unchanged, and at this time, according to the setting position of the second pressure detecting unit 122b, it can be determined that the interactive device moves to the right. Then, according to the moving direction of the interactive device at each moment, the motion trail of the interactive device can be generated.
Also for example, when the interactive apparatus moves to the upper left, the pressure values of the pressure signals of the first pressure detecting unit 122a located at the left side and the fifth pressure detecting unit 122e located at the upper side increase, while the magnitude of the pressure values of the pressure signals of the other pressure detecting units is substantially unchanged, and at this time, according to the setting positions of the first pressure detecting unit 122a and the fifth pressure detecting unit 122e, it can be determined that the interactive apparatus moves to the upper left. Then, according to the moving direction of the interactive device at each moment, the motion trail of the interactive device can be generated.
In this embodiment, the pressure detection assembly includes six pressure detection units, and changes of air pressure in different directions can be sensed through the six pressure detection units, so that the moving direction of the interactive device can be determined, and the detection accuracy can be improved.
In yet another alternative embodiment, the pressure detecting assembly 12 includes at least two first pressure detecting units, at least two second pressure detecting units, at least two third pressure detecting units, at least two fourth pressure detecting units, at least two fifth pressure detecting units, and at least two sixth pressure detecting units; the first pressure detection unit and the second pressure detection unit are arranged along a first direction, and the sensing directions of the first pressure detection unit and the second pressure detection unit are opposite; the third pressure detection unit and the fourth pressure detection unit are arranged along a second direction, and the sensing directions of the third pressure detection unit and the fourth pressure detection unit are opposite; the fifth pressure detection unit and the sixth pressure detection unit are arranged along a third direction, and the sensing directions of the fifth pressure detection unit and the sixth pressure detection unit are opposite; the first direction, the second direction and the third direction are vertical to each other. Therefore, for the same induction direction, a plurality of pressure detection units are arranged, whether the interactive equipment moves towards the direction or not is determined according to the plurality of pressure detection units, and the detection accuracy can be further improved.

Step S4220, determining a target pressure detection unit according to the pressure signal output by each pressure detection unit, wherein the target pressure detection unit is a pressure detection unit in which a pressure value of the pressure signal is greater than a preset first threshold value.
The first threshold may reflect the pressure of ambient air on the interactive device. When the pressure value of the pressure signal of the pressure detection unit is greater than the first threshold, it is described that the pressure generated by the ambient air is applied to the sensing surface corresponding to the pressure detection unit, that is, the interaction device and the air around the sensing direction of the pressure detection unit move relatively, and it can be determined that the interaction device moves towards the sensing direction of the pressure detection unit. When the pressure value of the pressure signal of the pressure detection is smaller than or equal to the first threshold, it is described that the sensing surface corresponding to the pressure detection unit is not subjected to the pressure generated by the ambient air, that is, the interactive device and the air around the sensing direction of the pressure detection unit do not move relatively, and it can be determined that the interactive device does not move towards the sensing direction of the pressure detection unit. It should be noted that the first threshold may be set by a person skilled in the art according to practical experience or simulation test results, and the embodiment of the present disclosure is not limited thereto.

Here, it should be noted that one or more target pressure detection units may be provided.

Taking the example of the interactive apparatus shown in fig. 1, the interactive apparatus includes six pressure detection units, i.e., a first pressure detection unit 122a, a second pressure detection unit 122b, a third pressure detection unit 122c, a fourth pressure detection unit 122d, a fifth pressure detection unit 122e, and a sixth pressure detection unit 122 f. In the process of using the head-mounted display device, pressure signals output by the first pressure detection unit 122a, the second pressure detection unit 122b, the third pressure detection unit 122c, the fourth pressure detection unit 122d, the fifth pressure detection unit 122e, and the sixth pressure detection unit 122f are acquired, respectively.

For example, the pressure value of the pressure signal of the second pressure detecting unit 122b is greater than the preset first threshold value, and the pressure values of the pressure signals of the other pressure detecting units are not greater than the preset first threshold value, that is, the second pressure detecting unit 122b is the target pressure detecting unit. At this time, since the second pressure detecting unit 122b is disposed at the right side of the interactive apparatus, and the sensing surface of the second pressure detecting unit 122b faces the right side of the interactive apparatus, based on this, it can be determined that the right air of the interactive apparatus generates an acting force on the interactive apparatus, and thus it can be determined that the interactive apparatus moves rightward. It should be noted here that the orientation and the installation position of the sensing surface of the pressure detection unit are determined relative to the coordinate system of the interaction device. In general, during the virtual reality experience of the user using the interactive device, the front of the interactive device faces the user, the first pressure detecting unit 122a is located on the left side of the interactive device, and the sensing surface of the first pressure detecting unit 122a faces the left side of the interactive device, and is used for sensing a change in air pressure from the left side of the interactive device. The second pressure detecting unit 122b is located at the right side of the interactive apparatus, and the sensing surface of the second pressure detecting unit 122b faces the right side of the interactive apparatus for sensing a change in air pressure from the right side of the interactive apparatus.
Also for example, the pressure values of the pressure signals of the first pressure detecting unit 122a located on the left side and the fifth pressure detecting unit 122e located on the upper side are greater than a preset first threshold value, and the pressure values of the pressure signals of the other pressure detecting units are not greater than the preset first threshold value, that is, the first pressure detecting unit 122a and the fifth pressure detecting unit 122e are target pressure detecting units. At this time, it can be determined that the interactive apparatus moves to the upper left due to the orientation and the arrangement orientation of the sensing surfaces of the first pressure detecting unit 122a and the fifth pressure detecting unit 122 e. It should be noted here that the orientation and the installation position of the sensing surface of the pressure detection unit are determined relative to the coordinate system of the interaction device. In general, during the virtual reality experience of the user using the interactive device, the front of the interactive device faces the user, the first pressure detecting unit 122a is located on the left side of the interactive device, and the sensing surface of the first pressure detecting unit 122a faces the left side of the interactive device, and is used for sensing a change in air pressure from the left side of the interactive device. The fifth pressure detecting unit 122e is located on the upper side of the interactive device, and the sensing surface of the fifth pressure detecting unit 122e faces the upper side of the interactive device and is used for sensing the change of the air pressure from the upper side of the interactive device.
