Step 104: providing a blank touch feeling to a preset position by driving a target ultrasonic transmitter under the condition that the action of the equipment wearing part meets a preset condition;
wherein the target ultrasonic emitter comprises one or more ultrasonic emitters of a plurality of ultrasonic emitters arranged on the wearing belt body; the preset positions include, but are not limited to, the equipment wearing part of an operator, the finger pointing position and the gesture volatilizing position, namely, the space positions outside the equipment wearing part and the equipment wearing part can be provided with a space touch sense through the target ultrasonic transmitter.
In the embodiment of the application, when the equipment wearing part of the operator wears the above-mentioned spaced touch equipment and makes actions, by acquiring the actions of the equipment wearing part of the operator and the position of the equipment wearing part, then judging the acquired actions of the equipment wearing part, and under the condition that the actions of the equipment wearing part meet the preset conditions, driving the target ultrasonic transmitter, which comprises one or more ultrasonic transmitters in a plurality of ultrasonic transmitters arranged on the wearing belt body, to provide spaced touch to the preset position, and because the blocked positions of different actions are different, driving the target ultrasonic transmitter arranged on the wearing belt body of the spaced touch equipment which is not blocked is selected so as to provide accurate spaced touch for the equipment wearing part of the operator.
For example, the space touch sensing device may be a hand strap that is wearable from the root of a finger to the palm, so that an operator does not need to hold the hand strap, and when the finger is bent, the ultrasonic transmitter of the virtual reality device and the terminal device may be blocked and cannot act on the abdomen, palm and other parts of the finger, and then the ultrasonic transmitter on the space touch sensing device may transmit ultrasonic waves to the abdomen, palm and other parts of the finger, so as to provide space touch for the operator.
In addition, fig. 3 shows a schematic structural diagram of a flexible circuit board of a space-apart touch sensing device according to an embodiment of the present application, and as shown in fig. 3, the flexible circuit board 30 is provided with a power module 31, a gyroscope 32, a processor 33, a sensor 34, a wireless lan/bluetooth module 35, and an ultrasonic driving module 36. Wherein the power module 31 is used for connecting with a power supply of the spaced touch sensing device; the gyroscope 32 and the sensor 34 are used for detecting the movement strength of the equipment wearing part of the operator, such as speed, acceleration and azimuth when the equipment wearing part moves; the processor 33 is configured to process the detected movement intensity of the wearable device to obtain information that can instruct the operation of the ultrasonic driving module 36; the wireless lan/bluetooth module 25 is configured to perform communication connection with a virtual reality device, a terminal device, etc.; the ultrasonic driving module 26 is used for driving the ultrasonic emitter to make the ultrasonic emitter emit ultrasonic waves.
In one implementation, the act of acquiring the device wearing part of the operator in step 102 may include the following steps:
step 1021: decomposing the action of the equipment wearing part through a processor to obtain an inscribed plane and/or an circumscribed plane of the equipment wearing part in the action;
for example, the finger abdomen will bend toward the palm center during the space-saving hand holding operation, and at this time, the inscribed plane includes the planes of the finger abdomen and palm center of each section, and the circumscribed plane includes the planes of the finger back and hand back of each section.
Step 1022: and calculating the included angle between the inscribed plane and/or the circumscribed plane and the plane of the negative transverse axis of the display of the terminal equipment.
Wherein the processor is disposed on at least one of: the flexible circuit board of the spaced touch sensing device, the Virtual Reality device, and the terminal device, the Virtual Reality device may include Virtual Reality (VR) glasses and a head-mounted Virtual Reality device.
In the embodiment of the application, the processor can be arranged on the flexible circuit board, the virtual reality device and the terminal device of the spaced touch sensing device through the various inscribed planes and/or circumscribed planes obtained by decomposing the actions of the processor on the wearing part of the device, namely, the processor which is suitable for the current situation can be selected for decomposing the actions of the wearing part of the device through the actual use situation, then the included angle between the tangential planes and the plane on which the negative transverse axis of the display of the terminal device is positioned is calculated, so that the relation between the actions of the wearing part of the device and the display of the terminal device is measured through the included angle, and further the ultrasonic transmitter can be indicated to transmit ultrasonic waves through judging whether the included angle meets the preset condition or not, thereby providing the spaced touch sensing for the wearing part of the device.
In one implementation manner, the target ultrasonic transmitter further includes one or more ultrasonic transmitters of a plurality of ultrasonic transmitters disposed on the terminal device, and further includes one or more ultrasonic transmitters of a plurality of ultrasonic transmitters disposed on the virtual reality device; the step 104 may include:
(1) Under the condition that the included angle between the inscribed plane and the plane of the negative transverse axis of the display of the terminal equipment is larger than a preset threshold value, providing a blank touch to the preset position by driving an ultrasonic transmitter of the blank touch equipment;
for example, the finger abdomen will bend towards the palm centre of the palm in the spaced-apart hand holding action, the threshold value is set to 90 degrees, when the included angle between the inscribed plane of hand and the plane of the negative-going transverse axis of the display of the terminal equipment is greater than 90 degrees, the inscribed plane of finger abdomen and palm centre of the palm is in the position that the ultrasonic transmitter of the terminal equipment can not act on, and the ultrasonic transmitter of the spaced-apart touch equipment worn on the wearing part of the equipment can act on, so the ultrasonic transmitter of the drive spaced-apart touch equipment provides spaced-apart touch for the wearing part of the equipment.
(2) And under the condition that the included angle between the inscribed plane and the plane of the negative transverse axis of the display of the terminal equipment is smaller than or equal to the preset threshold value, providing a space touch sense for the preset position by driving the ultrasonic transmitter of the terminal equipment.
For example, the palm is isolated, the threshold is set to 90 degrees, at this time, the palm center faces the display of the terminal device, the angle between the inscribed plane where the palm center is located and the plane where the negative transverse axis of the display of the terminal device is located is smaller than or equal to 90 degrees, and the ultrasonic transmitter of the terminal device can act on the palm center, so that the ultrasonic transmitter of the terminal device is driven to provide an isolated touch for the wearing part of the device.
(3) Under the condition that the included angle between the circumscribed plane and the plane of the negative transverse axis of the display of the terminal equipment is larger than the preset threshold value, providing a space-apart touch sense to the preset position by driving the ultrasonic transmitter of the terminal equipment;
for example, the space-saving handshake action sets the threshold to 90 degrees, and when the angle between the circumscribed plane of the back of the hand and the plane of the negative transverse axis of the display of the terminal equipment is greater than 90 degrees, the back of the hand faces the display of the terminal equipment at the moment, and the ultrasonic transmitter of the terminal equipment can act on the back of the hand, so that the ultrasonic transmitter of the terminal equipment is driven to provide space-saving touch feeling for the wearing part of the equipment.
(4) And under the condition that the included angle between the circumscribed plane and the plane of the negative transverse axis of the display of the terminal equipment is smaller than or equal to the preset threshold value, providing a space touch sense for the preset position by driving the ultrasonic transmitter of the virtual reality equipment.
For example, when the finger is massaged at intervals, the threshold value is set to be 90 degrees, when the finger web faces the display of the terminal equipment and the finger back faces the opposite direction of the display of the terminal equipment, when the virtual finger massages the finger, the included angle between the circumscribed plane of the finger back and the plane of the negative transverse axis of the display of the terminal equipment is smaller than or equal to 90 degrees, the ultrasonic transmitter of the terminal equipment cannot act on the finger back, and therefore the ultrasonic transmitter of the virtual reality equipment is driven to provide an interval touch feeling for the wearing part of the equipment.
In the embodiment of the application, the target device for providing the space touch feeling for the device wearing part is determined by judging the preset condition met by the included angle between the decomposed internal tangent plane and/or external tangent plane of the action of the device wearing part and the plane of the negative transverse axis of the display of the terminal device, and the space touch feeling is provided for the device wearing part by driving the target ultrasonic transmitter arranged on the target device.
In one implementation manner, in a case where the motion of the wearable device meets the preset condition, the method for providing the blank touch feeling before providing the blank touch feeling to the preset position by driving the target ultrasonic transmitter may further include: according to the action of the equipment wearing part, determining a part for providing a space touch for the equipment wearing part; wherein the site comprises the inscribed plane and/or the circumscribed plane.
In the embodiment of the application, because of different actions of the wearing part of the device, whether a blank touch is required to be provided for each part of the wearing part of the device is required to be determined, and before judging whether the actions of the wearing part of the device meet the preset conditions, the part providing the blank touch for the wearing part of the device can be determined by driving the ultrasonic transmitter at the position to provide the blank touch for the wearing part of the device.
For example, the space-isolation palm only needs to provide space-isolation touch on the inscribed plane where the palm of the opponent is located; the finger back of the hand, the circumscribed plane where the hand back is located, and the inscribed plane where the finger abdomen and palm center are located are all required to provide a space touch feeling, wherein the touch feeling also needs to be adjusted timely according to different handshake degrees.
In one implementation manner, the providing the space-apart touch feeling to the preset position by driving the target ultrasonic transmitter may include: the ultrasonic driving module is used for driving the target ultrasonic transmitter to transmit ultrasonic signals to the preset position, wherein the ultrasonic driving module is arranged at least one of the following: the flexible circuit board of the space touch sensing device, the virtual reality device and the terminal device are used for providing space touch sensing to a preset position through the target ultrasonic transmitter.
In one implementation, referring to fig. 3, a gyroscope and a sensor are disposed in the flexible circuit board; before the above-mentioned providing the spaced touch feeling to the preset position by driving the target ultrasonic transmitter, the method may further include the steps of:
step 1041: acquiring the motion acceleration of the motion of the equipment wearing part through a sensor and a gyroscope which are arranged on the flexible circuit board;
wherein, the energy intensity of the ultrasonic signal is controlled by the motion acceleration of the motion of the equipment wearing part.
Step 1042: and determining the energy intensity of the ultrasonic signal by the processor according to the corresponding relation between the motion acceleration and the energy intensity of the ultrasonic signal.
The corresponding relation between the motion acceleration and the energy intensity of the ultrasonic signal can be that when the acceleration is a, the energy intensity of the ultrasonic signal is 1s; when the acceleration is 2a, the energy intensity of the ultrasonic signal is 1.5s.
In the embodiment of the application, after the position providing the space touch feeling for the equipment wearing part and the equipment providing the space touch feeling for the equipment wearing part are determined, the energy intensity of the ultrasonic signal emitted by the equipment wearing part is determined through the corresponding relation between the acceleration of the action of the equipment wearing part and the energy intensity of the ultrasonic signal, so that the perception effect of the space touch feeling is enhanced.
