Referring to fig. 3 and fig. 4 together, fig. 3 is a schematic view of an application scenario provided in an embodiment of the present application, and fig. 4 is a schematic view of an equivalent circuit of a skin provided in the embodiment of the present application. The control method of the touch screen comprises the following steps:
in step S101, when a touch instruction is received, a touch point position is acquired.
As shown in fig. 3, when a user performs a touch operation on a touch screen, a touch instruction may be generated according to the touch operation, and the specific touch operation may include pressing a function key, pressing a combination function key, clicking the touch screen, double-clicking the touch screen, long-pressing the touch screen, performing a sliding operation on the touch screen, and the like. For example, when the touch operation is a single-click touch screen, the touch point position of a single-click point of a user is obtained; or when the touch operation is a sliding operation, acquiring the positions of partial touch points of the sliding operation, such as acquiring the positions of two touch points of a starting touch point and an ending touch point of the sliding operation.
In step S102, a corresponding target touch area is determined according to the touch point position.
And determining the coordinate position of the touch point in the touch screen according to the position of the touch point, and determining a corresponding target touch area according to the coordinate position. For example, the touch screen is divided into a plurality of touch areas, and the positions of the corresponding target touch areas are determined according to the coordinate positions of four points, as shown in fig. 3, the nth target touch area 112 is formed by four points a, B, C, and D, where the coordinate of the point a is (x 1, y 1), the coordinate of the point B is (x 2, y 2), the coordinate of the point C is (x 3, y 3), the coordinate of the point D is (x 4, y 4), and when the touch point position (x 4, y 4) is located in the nth target touch area, it can be determined that the target touch area position corresponding to the touch point is the nth target touch area 112.
In step S103, when the target touch area is located in the first touch area, the touch electrode is controlled to output a corresponding electrical stimulation signal.
And when the target touch area is positioned in the first touch area, controlling the touch electrode to output a corresponding electric stimulation signal. For example, the target touch area is an nth target touch area 112, and as can be seen from fig. 3, the nth target touch area 112 is located in the first touch area 110, so that the touch electrode of the nth target touch area 112 is controlled to output a corresponding electrical stimulation signal. The electrical stimulation signal is used for stimulating the skin of the user to enable the user to generate touch feeling.
In particular, the sense of touch is a basic human sense. Human skin senses the sense of touch are mainly obtained through four types of tactile receptors, which are respectively: meissner's corpuscle, merkel's disk, pacinian corpuscle, and Ruffini's ending, four tactile receptors are located below the epidermis layer, the base of the epidermis, the deep and subcutaneous tissues of the dermis layer, and the dermis layer and joints, respectively. The four sensors are distributed in the human skin unevenly, and sense the external temperature, humidity and vibration, and sense the deformation, stretching, activity and other information of the skin. The four sensors have different sensing ranges and are influenced by electric touch sense.
The inventor finds out through a large number of experiments that the current is directly used for stimulating receptors/nerve fiber bundles under the skin, the action potential of nerve fiber is triggered and is conducted to the sensory nerve center of the brain, the operator is enabled to generate the contact consciousness, and therefore the touch reappearance is achieved. The equivalent circuit of the skin is shown in fig. 4, where the equivalent circuit of the skin comprises the conductance Gm of the neural membrane, the capacitance Cm, and the conductance Ga of the medium inside the nerve, etc. When a current I passes through the skin surface, a potential distribution is generated on the skin surface, and the potential distribution Ψ generates a membrane current Im along the nerve axon, so as to further cause a voltage difference Vm on a membrane, namely, the stimulation of the nerve changes the voltage difference Vm of the nerve membrane by changing the external membrane potential Ψ. When the voltage difference Vm of the neural membrane reaches a certain threshold value, i.e., the current is large enough, the tactile receptors in the nerve endings are finally stimulated, and then the electric stimulation sensation is generated in the central nervous system.
In some embodiments, different types of electrical stimulation signals can be set according to the current magnitude of the electrical stimulation signals, for example, the current magnitude of a first preset electrical stimulation signal is a first level, the current magnitude of a second preset electrical stimulation signal is a second level, the current magnitude of a third preset electrical stimulation signal is a third level, the level magnitude can be in direct proportion to the current magnitude, the level magnitude can also be in inverse proportion to the current, each different level corresponds to a different control type of a touch instruction, when a finger of a user contacts a screen, the user is given electrical stimulation through a determined target touch electrode, and in order to enable the user to feel touch feeling brought by the electrical stimulation of different levels more clearly, the user can distinguish different touch instructions according to different touch feeling.
In some embodiments, different types of electrical stimulation signals can be set according to the frequency of the electrical stimulation signals for stimulating the user, each frequency range can correspond to one preset electrical stimulation signal, for example, when the stimulation frequency is 0.4-100HZ, the electrical stimulation signals can enable the user to generate a pressure feeling, when the stimulation frequency is 10-200HZ, the preset electrical stimulation signals can enable the user to generate itching and contact feelings, when the stimulation frequency is 40-800HZ, the preset electrical stimulation signals can enable the user to generate vibration and itching feelings, when the stimulation frequency is 740-1500HZ, the preset electrical stimulation signals can enable the user to generate vibration and feelings of micro-anesthesia, and each stimulation frequency range can be divided in detail to give more touch feelings to the user.
In some embodiments, different types of the electrical stimulation signals can be set according to combinations of the time length, the current and the frequency of the electrical stimulation signals, any two combinations or three combinations of the time length, the current and the frequency of the electrical stimulation signals can generate different touch sensations, and different combinations of the electrical stimulation signals can correspond to different touch instructions.
In view of the above, in the control method of the touch screen provided in the embodiment of the present application, when a touch instruction is received, a position of a touch point is obtained; determining a corresponding target touch area according to the position of the touch point; and when the target touch area is positioned in the first touch area, controlling the touch electrode to output a corresponding electrical stimulation signal. When a touch instruction positioned in a first touch area is received, the touch electrode of the first touch area is controlled to output a corresponding electrical stimulation signal, so that a user generates a corresponding electrical stimulation touch sense, and the diversity of touch sensing is increased.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a touch screen assembly according to an embodiment of the present disclosure. The touch screen assembly 200 includes a touch screen 10, touch electrodes 11, an insulating medium 420, a plate electrode 430, and a vibration unit 460, where the vibration unit 460 is disposed on an inner surface of the touch screen 10, the plate electrode 430 is disposed on an outer surface of the touch screen 10, the insulating medium 420 is disposed on an outer surface of the plate electrode 430, the touch electrodes 11 are disposed on an outer surface of the insulating medium 420, and the first voltage driving module 410 is formed by combining the touch electrodes and the insulating medium.
The touch surface of the touch screen 10 may be formed by a touch electrode array formed by using an ITO transparent material, which is covered on the touch screen 10, and the touch electrode array is formed by using the ITO transparent material, which is an electrode array formed by the touch electrodes 11 in the figure.
The touch electrode 11 directly stimulates the receptor/nerve fiber bundle under the skin with current to trigger the action potential of nerve fiber, which is conducted to the sensory nerve center of brain to make the operator generate the contact consciousness, thereby realizing the touch reappearance.
In an ideal flat model, conductive plates are on both sides and an insulating medium 420 is in the middle. When an electric field is present across the plate, the insulating medium 420 is subjected to electrostatic forces. The flat plate model may have a width, a length, and a height.
Neglecting edge effects, the capacitance is defined by:
the electrical energy between the two plate electrodes 430 is:
according to the virtual work principle, the electrostatic force between the two plate electrodes 430 is:
where ε is the dielectric constant of the insulator medium, A is the area of the conductor above the insulator, d is the thickness of the insulator medium, and V is the voltage difference between the two conducting layers. The friction force is equal to the coefficient of friction multiplied by the pressure. Thus, the frictional force can be varied by varying the electrostatic force of the finger skin.
In practical use, a finger can be equivalent to the flat plate electrode 430 on the touch surface of the screen, and the friction force between the finger and the touch area can be changed by using the same principle, so that the touch sense is realized. The air squeeze film effect is the result of mutual influence of the viscosity and the compressibility of air molecules, and an alternating electric signal is applied to one of the surfaces which are relatively parallel to generate forced vibration. When the operator's finger is located above the forced vibration support screen, air molecules between the two are periodically squeezed due to the high-frequency vibration of the vibration unit 460 below the screen, and the air molecules cannot escape in time in a vibration cycle, so that high-pressure air with a certain thickness is generated between the finger and the touch surface of the screen. Thereby changing the coefficient of friction of the touch area. The friction coefficient is adjusted by controlling different vibration frequencies, so that different tactile sensations are generated.
Referring to fig. 5 and fig. 6 together, fig. 6 is another schematic flow chart of a control method of a touch screen according to an embodiment of the present disclosure. The screen control method comprises the following steps:
in step S201, when a touch instruction is received, a touch point position is acquired.
When a user performs a touch operation on the touch screen, a touch instruction may be generated according to the touch operation, the specific touch operation may include pressing a function key, pressing a combination function key, clicking the touch screen, double-clicking the touch screen, long-pressing the touch screen, performing a sliding operation on the touch screen, and the like, and when the electronic device receives the touch instruction, a touch point position of the touch operation is obtained. For example, when the touch operation is a single-click touch screen, the touch point position of a single-click point of a user is obtained; or when the touch operation is a sliding operation, acquiring the positions of partial touch points of the sliding operation, such as acquiring the positions of two touch points of a starting touch point and an ending touch point of the sliding operation.
In step S202, a corresponding target touch area is determined according to the touch point position.
And determining the coordinate position of the touch point in the touch screen according to the position of the touch point, and determining a corresponding target touch area according to the coordinate position. For example, the touch screen is divided into a plurality of touch areas, and the positions of the corresponding target touch areas are determined according to the coordinate positions of four points, as shown in fig. 3, the nth target touch area 112 is formed by four points a, B, C, and D, where the coordinate of the point a is (x 1, y 1), the coordinate of the point B is (x 2, y 2), the coordinate of the point C is (x 3, y 3), the coordinate of the point D is (x 4, y 4), and when the touch point position (x 4, y 4) is located in the nth target touch area, it can be determined that the target touch area position corresponding to the touch point is the nth target touch area 112.
In step S203, when the target touch area is located in the first touch area, the touch electrode is controlled to output a corresponding electrical stimulation signal.
And when the target touch area is positioned in the first touch area, controlling the touch electrode to output a corresponding electric stimulation signal. For example, the target touch area is an nth target touch area 112, as shown in fig. 3, the nth target touch area 112 is located in the first touch area 110, and thus, the touch electrode of the nth target touch area 112 is controlled to output a corresponding electrical stimulation signal. The electrical stimulation signal is used for stimulating the skin of the user to enable the user to generate touch feeling.
In step S204, a manipulation type of the touch instruction is acquired.
The control type of the touch instruction is obtained, and the specific control type of the touch instruction may be to open a certain application, close a certain application, enter or exit a certain interface, complete input of characters, select related content, or the like.
In step S205, the vibration unit is controlled to vibrate at a corresponding vibration frequency according to the manipulation type.
The vibration unit is controlled to vibrate at the corresponding vibration frequency according to the control type. For example, when the manipulation type is to start an application, the corresponding first vibration frequency is 600-1000HZ, when the manipulation type is to close an application, the corresponding second vibration frequency is 500-9000HZ, when the manipulation type is to enter or exit an interface, the corresponding third vibration frequency is 10-200HZ, or when the manipulation type is to complete the input of characters or select related contents, the corresponding fourth vibration frequency is 0.4-200HZ, and the like.
The touch screen comprises a touch area, a vibration unit, a high-pressure air film and an air compression film, wherein the vibration unit is arranged below the touch area of the touch screen, the high-frequency vibration of the vibration unit enables air molecules between a finger and the touch area to generate an extrusion aggregation phenomenon, the high-pressure air film is formed, an air compression film effect is generated, the air compression film effect is a result of mutual influence of viscosity and compressibility of the air molecules, and an alternating electric signal is applied to one surface which is parallel to the surface to enable the surface to generate forced vibration. When the fingers of an operator are positioned above the support flat plate forced to vibrate, air molecules between the two are periodically extruded due to the high-frequency vibration of the flat plate, and the air molecules cannot escape in time in vibration circulation, so that high-pressure air with a certain thickness is generated between the two surfaces. And then changing the friction coefficient of the touch area, adjusting the friction coefficient by controlling different vibration frequencies, and further generating different tactile sensations, specifically, changing the friction coefficient of the touch area corresponding to the vibration unit by changing the vibration frequency of the vibration unit.
In step S206, a corresponding electrical stimulation touch sensation is generated according to the combination of the touch electrode output corresponding electrical stimulation signal and the corresponding vibration frequency of the vibration unit.
And generating corresponding electrical stimulation touch feeling according to the combination of the electrical stimulation signal output by the touch electrode and the corresponding vibration frequency of the vibration unit. For example, when the manipulation type is to start an application, a first electrical stimulation touch sensation, which can cause a user to generate a vibration and itch sensation, is generated according to a first preset stimulation signal and a corresponding first vibration frequency. When the control type is to close a certain application, a second electrical stimulation touch sense is generated according to a second preset stimulation signal and a corresponding second vibration frequency, and the second electrical stimulation touch sense can also enable a user to generate vibration and itching feeling. And when the manipulation type is entering or exiting a certain interface, generating a third electrical stimulation touch feeling according to a third preset stimulation signal and a corresponding third vibration frequency, wherein the third electrical stimulation touch feeling can enable a user to generate itching and contact feelings. Or when the control type is that the input of characters is finished or related contents are selected, generating a fourth electrical stimulation touch feeling according to a fourth preset stimulation signal and a corresponding fourth vibration frequency, wherein the fourth electrical stimulation touch feeling can enable a user to generate a slight pressure feeling and the like. Different electrical stimulation touch senses are generated by combining different electrical stimulation signals output by the touch electrodes and different vibration frequencies of the vibration units, so that users have different touch senses under different control types, and the diversity of touch senses is increased.
In view of the above, in the control method of the touch screen provided in the embodiment of the present application, when a touch instruction is received, a position of a touch point is obtained; determining a corresponding target touch area according to the position of the touch point; and when the target touch area is positioned in the first touch area, controlling the touch electrode to output a corresponding electrical stimulation signal. When a touch instruction positioned in a first touch area is received, the touch electrode in the first touch area is controlled to output a corresponding electrical stimulation signal, and a corresponding electrical stimulation touch sense is generated according to the combination of the corresponding electrical stimulation signal output by the touch electrode and the corresponding vibration frequency of the vibration unit, so that a user can feel the corresponding touch sense, and the diversity of touch sensing is increased.
Referring to fig. 7, fig. 7 is a schematic flowchart of another flow chart of a control method of a touch screen according to an embodiment of the present application, where the control method of the touch screen specifically includes the following steps:
in step S301, when a touch instruction is received, a touch point position is acquired.
When a user performs a touch operation on the touch screen, a touch instruction may be generated according to the touch operation, the specific touch operation may include pressing a function key, pressing a combination function key, clicking the touch screen, double-clicking the touch screen, long-pressing the touch screen, performing a sliding operation on the touch screen, and the like, and when the electronic device receives the touch instruction, a touch point position of the touch operation is obtained. For example, when the touch operation is a single-click touch screen, the touch point position of a single-click point of a user is obtained; or when the touch operation is a sliding operation, acquiring the positions of partial touch points of the sliding operation, such as acquiring the positions of two touch points of a starting touch point and an ending touch point of the sliding operation.
In step S302, a corresponding target touch area is determined according to the touch point position.
And determining the coordinate position of the touch point in the touch screen according to the position of the touch point, and determining a corresponding target touch area according to the coordinate position. For example, the touch screen is divided into a plurality of touch areas, and the positions of the corresponding target touch areas are determined according to the coordinate positions of four points, as shown in fig. 3, the nth target touch area 112 is formed by four points a, B, C, and D, where the coordinate of the point a is (x 1, y 1), the coordinate of the point B is (x 2, y 2), the coordinate of the point C is (x 3, y 3), the coordinate of the point D is (x 4, y 4), and when the touch point position (x 4, y 4) is located in the nth target touch area, it can be determined that the target touch area position corresponding to the touch point is the nth target touch area 112.
In step S303, when the target touch area is located in the first touch area, a manipulation type of the touch instruction is acquired.
And when the target touch area is located in the first touch area, acquiring the control type of the touch instruction. For example, the target touch area is an nth target touch area 112, and as can be seen from fig. 3, if the nth target touch area 112 is located in the first touch area 110, the manipulation type of the touch instruction is obtained.
