The present invention provides smart glasses, which may be AR glasses or VR glasses, and the following embodiments of the present invention are described by taking AR glasses as an example. AR technology is a special way of observing the real world, either directly or through a video device such as a camera, using computer generated content such as still images, audio or video to augment the visual effects of the real world. The appearance style of current AR product is various, has glasses, the head shows, and is dull and stereotyped etc, and wherein the form of AR glasses is similar simple glasses, wears the convenience, compares the head and shows lighter weight more, is accepted by the user more easily, and consequently, the AR glasses have become the best mode that the user experienced the AR. AR glasses require the user to see the real world, present an augmented effect to the real world, can enable the integration of virtual and real world, and then enable human interaction with the augmented real world. Also, AR glasses require both hands of the user to interact with these digital objects. Due to the development of smart phones, users are used to navigate screen contents through a series of strokes, slides or similar actions, and therefore, most AR glasses place a sliding touch key at a suitable position to implement control signal input to operate an AR device, but the touch configuration of the current AR glasses usually includes a capacitive film area, which may cause the smart glasses to be easily touched by mistake, and thus inconvenience is brought to the users.
In order to solve the above problems, referring to fig. 1 to 5, the present invention provides smart glasses including:
a housing 100, a touch area 110 being provided on the housing 100;
the capacitance diaphragm 11 is arranged on the inner side surface of the shell and is arranged corresponding to the touch area; the capacitance diaphragm 11 is used for generating a corresponding touch detection signal when the touch area is touched and operated by a user;
a piezoelectric sheet 21 disposed on a side of the capacitive diaphragm 11 away from the housing 100 to form a stacked structure with the touch area and the capacitive diaphragm 11, wherein the piezoelectric sheet 21 is configured to generate a corresponding pressing detection signal when the touch area is pressed by a user;
an insulating sheet 40 interposed between the capacitive diaphragm 11 and the piezoelectric sheet 21;
the main controller 30 is electrically connected to the capacitive diaphragm 11 and the piezoelectric sheet 21, and the main controller 30 is configured to determine that a current user touch operation is an effective operation when receiving the touch detection signal and the press detection signal at the same time, and enter a user input mode to generate a corresponding smart glasses control strategy according to the received touch detection signal.
In this embodiment, the intelligent glasses include frame, lens, glasses leg, component parts such as functional device before the glasses, and casing 100 can be the casing 100 of glasses leg, and this casing 100 is formed with at least one holding chamber, and casing 100 can set up to different shape, size according to the difference of glasses type, and this casing 100 can have preceding shell and backshell and enclose to close and be formed with the holding chamber that supplies installation such as control terminal main control board, battery. The casing 100 may further be provided with mounting positions or through holes for mounting keys, a microphone, a speaker, sound, and pickup, and the front casing and the rear casing may be fixed by means of fasteners, etc.
The housing 100 is provided with a touch area 110, and the touch area 110 can be touched and pressed by a user, so that the capacitive diaphragm 11 and the piezoelectric sheet 21 provided in the touch area 110 can sense the operation of the user. It will be appreciated that the human tissue is saturated with conductive electrolyte beneath the skin, so that when the skin comes into contact with the capacitive diaphragm 11, the capacitive diaphragm 11 will generate an electrical signal. Based on this, when the smart glasses are in operation, the capacitive diaphragm 11 can be used to detect whether a user's skin, such as a finger, a palm, a back of a hand, etc., is in contact with the touch area 110, and the capacitive diaphragm 11 detects a change in a capacitive parameter, such as a dielectric constant and a capacitance of a capacitive film, caused by the user's skin contacting the touch area 110, and converts the change into a voltage signal, i.e., a touch detection signal, and sends the voltage signal to the main controller 30 in the smart glasses, so that the main controller 30 can detect whether the capacitive diaphragm 11 is in contact with the skin, and further determine whether the user touches the smart glasses. For example, if capacitive diaphragm 11 does not generate an electrical signal, it may be determined that the user's skin is not touching touch area 110.
In this embodiment, the piezoelectric sheet 21 deforms when the user presses the touch area 110, and generates voltage signals with different magnitudes according to different forces applied by the user on the housing 100. The piezoelectric sheet drive IC22 may perform signal processing, such as amplification, analog-to-digital conversion, and the like, on the voltage signal generated by the piezoelectric sheet 21, and output the processed voltage signal to the main controller 30.
In this embodiment, the capacitor diaphragm 11 may be implemented by adhering a plastic film to a metal plate, and a thin metal layer is plated on a surface of the film contacting the metal plate, and the film may be charged with charges to form an electrode plate of the variable capacitor. When a human body approaches the mobile terminal, the capacitance diaphragm 11 and the human body form a coupling capacitor, the capacitance diaphragm 11 is charged with charges, and the human body tissue below the human body skin is filled with conductive electrolyte, so that when the human body approaches the capacitance diaphragm 11 of the mobile terminal, a charge polarization phenomenon is generated in the coupling capacitor, charges with opposite polarities and equal sizes are generated on the upper surface and the lower surface of the capacitor, and the charge amount is inversely proportional to the approaching distance of the human body. When the human skin touches the touch area 110, the positive and negative polarities of the charges change accordingly.
Specifically, when a human body approaches, the distance between the capacitive diaphragm 11 and the human body changes, that is, the distance between two plates of the capacitor changes, and as can be seen from electrostatics, for a parallel plate capacitor, the following relationship is given:
C=ε·S/L （1）
wherein epsilon is the dielectric constant, S is the area of two polar plates in the capacitor formed by the capacitor diaphragm 11 and the human body, and L is the distance between the human body and the capacitor diaphragm 11, as can be seen from the formula (1), the capacity of the capacitor is in direct proportion to the dielectric constant of the medium, in direct proportion to the area of the two polar plates, and in inverse proportion to the distance between the two polar plates.
In addition, when a capacitor is charged with Q charge, the two plates of the capacitor will form a certain voltage, which has the following relationship:
C=Q/V （2）
wherein, Q is the charged quantity of the capacitor formed by the human body and the capacitor diaphragm 11, namely the charge, the charge is fixed in one capacitor, when the touch of the human body can change the distance between the two polar plates of the capacitor, the dielectric constant, as can be known from the formula (1), the change of the dielectric constant must generate a change of Δ C, as can be further known from the formula (2), because of the change of Δ C, a change of Δ V can be generated.
Referring to fig. 2, fig. 2 shows a laminated structure a in which the touch area 110, the capacitive diaphragm 11, the insulating sheet 40, and the piezoelectric sheet 21 are laminated in this order. It can be understood that when the user presses the touch area 110, the voltage signals generated by the capacitive diaphragm 11 and the piezoelectric sheet 21 need to be received at the same time, that is, one action needs to generate two detection signals, so that the capacitive diaphragm 11 and the piezoelectric sheet 21 need to be stacked, and both are devices for generating analog signals. For this reason, the two are required to be isolated to reduce mutual interference between the two. In this embodiment, the insulation sheet 40 may be implemented by a PC-isolation diaphragm, and the insulation sheet 40 is used for insulating the capacitor diaphragm 11 from the piezoelectric sheet 21
It can be understood that when the user touches the touch area 110 unconsciously, the control signal input is not needed to be realized, and when the user touches the smart glasses, the capacitive diaphragm 11 also senses the touch of the user and generates an electrical signal, so that the main controller 30 determines that the user needs to control the smart glasses by mistake, and then triggers by mistake, which brings inconvenience to the user.
For this reason, the present embodiment is further provided with the piezoelectric sheet 21, the piezoelectric sheet 21 is provided in the touch area 110 together with the capacitive diaphragm 11, and the user can press the touch area 110 while contacting the touch area 110. The piezoelectric sheet 21 is provided with a piezoelectric sheet 21 or a piezoelectric sensor, etc., when a user presses any position of the touch area 110, the piezoelectric sheet 21 can detect the change of the force of the touch area 110, the piezoelectric sheet 21 converts the detected force change into a voltage signal, if the voltage signal exceeds a certain threshold, it means that the magnitude of the pressing force exceeds a certain threshold, the main controller 30 receives the voltage signal converted by the piezoelectric sheet 21, and determines whether the pressing force is effective or not according to the magnitude of a preset threshold. By the arrangement, when a user needs to operate the smart glasses, the user firstly presses any position of the touch area 110, and the touch area 110 is also contacted when the user presses, so that when the pressure applied to the touch area 110 by the user reaches a certain threshold value, the capacitive diaphragm 11 and the piezoelectric sheet 21 can be simultaneously sensed, the capacitive diaphragm 11 outputs a touch detection signal, and the piezoelectric sheet 21 also outputs a press detection signal.
The main controller 30 may be a central processing unit in the smart glasses, or may be a microprocessor specially used for inputting a user control signal, and the microprocessor may process, compare, and analyze the piezoelectric patch 21 and the voltage signal output by the piezoelectric patch 21 to determine whether the user touches the touch area 110 or presses the touch area 110. In this embodiment, the main controller 30 may indicate whether the touch detection signal and/or the press detection signal is received according to the received voltage signal. For example, if the pressure applied to the touch area 110 by the user reaches a certain threshold, it indicates that the press detection signal is received, if the pressure applied to the touch area 110 by the user does not reach the certain threshold, it indicates that the press detection signal is not received, and similarly, if the capacitance change applied to the touch area 110 by the user reaches the certain threshold, it indicates that the touch detection signal is received, and if the capacitance change applied to the touch area 110 by the user does not reach the certain threshold, it indicates that the touch detection signal is not received. The threshold value can be adjusted according to application requirements, and the sensitivity of the user in the process of operating the intelligent glasses can be adjusted by adjusting the threshold value, so that the user does not need to limit the operation.
The main controller 30 determines whether the user needs to operate the smart glasses according to the voltage signals output by the capacitive diaphragm 11 and the piezoelectric sheet 21, and when the user operates the touch area 110, if the main controller 30 can receive the touch detection signal and the press detection signal at the same time, it indicates that the current operation of the user is effective press, and determines that the signal input is effective according to the working condition of the smart glasses. At this time, the main controller 30 enters the user input mode, and will continue to receive the capacitive diaphragm 11 to sense the touch operation of the user and generate a corresponding touch detection signal, after entering the user input mode, the user can navigate the screen content by sliding, tapping or the like, such as turning pages during reading, zooming in and out the image, fast forwarding and rewinding during video playing, increasing and decreasing the volume, and so on. When entering the user input mode, the user can input the control signal through touch operation, and in the working process of the whole system, the false trigger determination is only performed when the pressing is detected for the first time, and if the finger does not leave the touch area 110, the second false trigger detection is not required, that is, the second pressing is not required to enter the user input mode. When entering the user input mode, the input of the control signal may also be realized by a pressing operation, or a combination of a touch operation and a pressing operation. For example, a sliding contact touch area 110, a single finger tap, a two finger tap, and the like.
The capacitive diaphragm 11 is arranged to generate a corresponding touch detection signal when the touch area 110 is touched by a user, and the piezoelectric sheet 21 is arranged to generate a corresponding press detection signal to the main controller 30 when the touch area 110 is pressed by the user, so that the main controller 30 determines that the current user touch operation is an effective operation when the touch detection signal and the press detection signal are simultaneously received, and enters a user input mode to generate a corresponding smart glasses control strategy according to the received touch detection signal. The invention can solve the problem of false triggering of the intelligent glasses.
Referring to fig. 1 to 5, in an embodiment, the main controller 30 is further configured to determine that a current user touch operation is an invalid operation and maintain a current control policy of the smart glasses when the touch detection signal is received and the press detection signal is not received.
In this embodiment, if the main controller 30 only receives the touch detection signal generated by the capacitive diaphragm 11, it may be that a user unintentionally touches the touch area 110, and the smart glasses do not really need to be operated, at this time, the capacitive diaphragm 11 senses the touch of the user and generates an electrical signal, and because the main board controller does not receive the voltage signal output by the capacitive diaphragm 11, or the voltage signal converted by the piezoelectric patch 21 is smaller than a preset threshold, at this time, the voltage signal sent by the capacitive diaphragm 11 is determined to be an invalid signal, and at this time, the main board controller does not perform any function processing, determines that the current touch operation of the user is an invalid operation, and maintains the current control strategy of the smart glasses, so that the smart glasses maintain the current working state.
Referring to fig. 1 to 5, in one embodiment, a piezoelectric sheet driving IC22 is disposed in series between the piezoelectric sheet 21 and the main controller 30.
In this embodiment, the number of the piezoelectric sheets 21 is plural, and the plural piezoelectric sheets 21 are disposed at intervals on the inner side surface of the casing 100; each of the piezoelectric sheets 21 is configured to detect a pressure change of the piezoelectric sheet 21 when the touch area 110 is operated by a user, convert the detected pressure change into a corresponding pressure detection signal, and output the corresponding pressure detection signal to the main controller 30, so as to trigger the main controller 30 to enter a user input mode when receiving the touch detection signal and simultaneously receiving a pressure detection signal output by any of the piezoelectric sheets 21.

For this purpose, referring to fig. 1 to 5, in an embodiment, the main controller 30 is further configured to drive the piezoelectric sheet 21 to operate after entering the user input mode, so as to generate vibration feedback to the touch area 110 corresponding to the user touch operation.
In this embodiment, in the user input mode, when a user touches the touch area 110, the capacitive diaphragm 11 outputs a touch detection signal along with an action of the user, for example, sliding the touch area 110, and the touch detection signal can locate the user action area, for example, generating a plane coordinate, and the main controller 30 can generate a corresponding control strategy according to the touch detection signal, and simultaneously drive the piezoelectric sheet 21 to generate a pressure in a direction toward the skin of the user, and act on the skin of the user through the housing 100, so as to generate a vibration feedback to the touch area 110 corresponding to the user when the user touches the touch area, and according to whether the vibration feedback is present, the user can know whether the current touch operation is successful.

In this embodiment, whether the touch detection signal and/or the press detection signal is received may be indicated according to the received voltage signal. For example, when the pressure applied to the touch area by the user reaches a certain threshold, it indicates that the press detection signal is received, and when the pressure applied to the touch area by the user does not reach the certain threshold, it indicates that the press detection signal is not received. The threshold value can be adjusted according to application requirements, and the sensitivity of the user in the process of operating the intelligent glasses can be adjusted by adjusting the threshold value, so that the method is not limited.
