The tactile sensation enhancing mechanism, the electronic device and the tactile sensation enhancing method provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic cross-sectional view of a haptic enhancement unit according to an embodiment of the present application along a first direction; fig. 2 is a schematic cross-sectional view of a haptic enhancement unit provided in an embodiment of the present application along a second direction. The first direction may be a direction perpendicular to the bottom of the receiving groove 11, and the second direction may be a direction parallel to the bottom of the receiving groove 11. The tactile sensation enhancing mechanism provided by the embodiment of the present application includes a control unit (not shown) and a tactile sensation enhancing unit 100.

As shown in fig. 1 and 2, the tactile sensation enhancing unit 100 includes: the magnetic device comprises a main body part 1, a magnetic fluid 2, a flexible packaging layer 3 and a magnetic part 4.

Wherein, the main body part 1 is provided with a containing groove 11, the magnetic fluid 2 is contained in the containing groove 11, and the flexible packaging layer 3 seals the notch of the containing groove 11; the magnetic member 4 is arranged in the containing groove 11, and the magnetic member 4 is arranged on the side wall of the containing groove 11 or on the bottom edge of the containing groove 11;

the control unit is used for adjusting the magnetic field of the magnetic fluid 2 acted by the magnetic part 4, so that the magnetic fluid 2 pushes the flexible packaging layer 3 to deform under the action of the magnetic field.

In an alternative embodiment, the magnetic member 4 may include an exciting coil, so that the magnitude and direction of the magnetic field generated by the magnetic member 4 can be changed by adjusting the magnitude and direction of the current flowing through the exciting coil. Of course, in the implementation, the magnetic member 4 may be any device capable of generating a magnetic field, and for convenience of description, in the embodiment of the present application, the magnetic member 4 includes an excitation coil as an example, and is not specifically limited herein.

In addition, the flexible packaging layer 3 can be a flexible film (e.g. polyimide film) so as to be able to deform following the displacement of the magnetic fluid 2, such as: as shown in fig. 3, when the magnetic fluid 2 gathers to the center of the receiving groove 11, the central region of the flexible sealing layer 3 is pushed out of the receiving groove 11 by the magnetic fluid 2, thereby forming a convex structure.

It should be noted that, in one embodiment, the magnetic member 4 may be disposed on a sidewall of the receiving slot 11, for example: assuming that the magnetic member 4 includes a coil, the coil may have a strip-shaped structure and extend along the sidewall of the accommodating slot 11, or a groove may be formed on the sidewall of the accommodating slot 11 to accommodate the coil therein. Like this, can follow the side direction drive magnetic current body 2 removal of accepting groove 11, need not to set up the coil in the tank bottom below or notch top of accepting groove 11, be favorable to simplifying the structure of sense of touch reinforcing mechanism to reduce its occupation space, and under the condition of establishing the sense of touch reinforcing mechanism subsides in flexible display below, this sense of touch reinforcing mechanism subsides and establishes the flexible display that also can promote the top and take place deformation.

In an embodiment, the magnetic member 4 may also be disposed at the bottom edge of the receiving slot 11, and the structure and principle of the magnetic member 4 are similar to those of the embodiment in which the magnetic member 4 may be disposed at the side wall of the receiving slot 11, except that in this embodiment, the magnetic member 4 may also be disposed against the bottom of the receiving slot 11 and located at the edge of the bottom of the receiving slot close to the side wall of the receiving slot 11, so that when the magnetic member 4 generates a magnetic field, an acting force of the magnetic field on the magnetic fluid 2 in the first direction can be promoted, and the first direction is a direction perpendicular to the bottom of the receiving slot 11, so as to promote the protrusion amount of the magnetic fluid 2 pushing the flexible encapsulation layer 3, which is beneficial to promoting the tactile experience.

In the embodiment of the application, the magnetic member 4 can generate a magnetic field to push the magnetic fluid 2 to move, and the magnetic fluid 2 is limited in the accommodating groove 11, so that when the magnetic fluid 2 moves, the flexible packaging layer 3 for closing the notch of the accommodating groove 11 is pushed to deform, so that the flexible packaging layer 3 protrudes out of the plane where the flexible packaging layer 3 is located to form a protrusion for tactile perception, and thus, a user can perceive the deformation of the flexible packaging layer 3 through touch, so as to realize tactile feedback. In addition, in this application embodiment, the control unit can control magnetic part 4 to adjust the magnetic field that magnetic part 4 produced, like this, under the magnetic field that magnetic part 4 produced changes, the atress of magnetic fluid 2 also can change, thereby adjusts the deformation that flexible encapsulation layer 3 took place, can promote the tactile feedback effect that has the electronic equipment of sense of touch reinforcing mechanism.

Optionally, the magnetic member 4 includes a coil, the control unit is located outside the accommodating slot 11, a through hole 40 is formed in the main body portion 1, and the coil is electrically connected to the control unit through the through hole 40.

In the present embodiment, the control unit is provided outside the housing tank 11, for example: a wiring layer 5 is provided one level below the main body portion 1, and a line of the control unit can be provided on this wiring layer 5. In this case, since the coil is disposed in the housing groove 11, it is necessary to provide a through hole 40 in the main body 1 so that the circuit of the control unit can be connected to the coil after passing through the through hole 40.

Of course, in implementation, the control unit may be disposed in the storage tank 11, and is not limited in particular.

Optionally, the control unit is configured to adjust at least one of a magnitude and a direction of the magnetic field generated by the magnetic member 4;

and/or the presence of a gas in the gas,

the main body 1 is made of a magnetic material.

In one embodiment, the protruding degree of the protruding structure formed on the flexible packaging layer 3 can be changed by adjusting the magnitude of the magnetic field generated by the magnetic member 4, and in addition, the shape of the protruding structure formed on the flexible packaging layer 3 can be changed by adjusting the direction of the magnetic field generated by the magnetic member 4.

In this way, by adjusting at least one of the magnitude and the direction of the magnetic field generated by the magnetic member 4, the sense of touch of the user to the haptic enhancement content formed by the haptic enhancement mechanism can be changed, so that the same haptic enhancement mechanism can generate different senses of touch, and the haptic feedback effect of the haptic enhancement mechanism is improved.

In one embodiment, the main body 1 is made of a magnetic isolation material, so that a plurality of haptic enhancement units 100 can be arranged in parallel, and magnetic field interference between different haptic enhancement units 100 is isolated by the magnetic isolation material, thereby improving the haptic feedback effect of the haptic enhancement mechanism.

Optionally, the tactile sensation enhancing mechanism comprises at least two tactile enhancing units 100;

the at least two tactile sensation enhancing units 100 are arranged in a matrix, and the main body 1 is made of soft magnetic material.

When at least two haptic enhancement units 100 are arranged in a matrix, the main body portions 1 of any two adjacent haptic enhancement units 100 are arranged side by side, and the main body portions 1 are made of a soft magnetic material, so that the direction of the magnetic field between any two adjacent haptic enhancement units 100 can be twisted by the soft magnetic material, thereby reducing magnetic field interference between the haptic enhancement units 100 and magnetic field interference outside the main body portion 1.

In an embodiment, the soft magnetic material may be a zinc-manganese alloy, a chromium-zirconium alloy, or the like, which may twist the direction of the magnetic field to shield the internal environment of the housing groove 11, so that the magnetic fields generated by the exciting coils between the haptic reinforcing units 100 do not interfere with each other, and may change the structural adaptation of the internal of the main body 1 to resist the influence of the magnetic field outside the main body 1, so that the induced magnetic field generated by the external circuit does not interfere with the magnetic fluid 2 in the housing groove 11.

Alternatively, as shown in fig. 2, the magnetic member 4 includes a first coil 411 and a second coil 412, and the first coil 411 and the second coil 412 are disposed at two adjacent sides of the accommodating slot 11.

In this embodiment, the first coil 411 and the second coil 412 are respectively disposed on two adjacent sides of the accommodating slot 11, and in operation, the control unit may control the first coil 411 to be energized and the second coil 412 to be not energized, or control the first coil 411 to be not energized and the second coil 412 to be energized, or control both the first coil 411 and the second coil 412 to be energized, so as to realize that the haptic enhancement unit 100 forms different forms of haptic enhancement contents on the flexible packaging layer 3. For example: when the first coil 411 is electrified and the second coil 412 is not electrified, a convex structure is formed on the flexible packaging layer 3 close to the first coil 411; when the first coil 411 is not electrified and the second coil 412 is electrified, a convex structure is formed on the flexible packaging layer 3 on one side close to the second coil 412; when the first coil 411 and the second coil 412 are both powered on, a convex structure is formed at the corner of the flexible packaging layer 3 close to the space between the first coil 411 and the second coil 412, so that different tactile senses can be fed back to a user through different forms of tactile sense enhancement contents, and the tactile feedback effect of the tactile sense enhancement mechanism is improved.

Of course, in an implementation, the magnetic member 4 may also include two coils disposed oppositely. Alternatively, as shown in fig. 2, the magnetic member 4 includes a first coil 411 and a third coil 413, and the first coil 411 and the third coil 413 are disposed on two sides of the accommodating cavity 11 opposite to each other.

In this embodiment, by controlling the energization of one or both of the first coil 411 and the third coil 413 which are oppositely arranged, the shape and/or the position of the protruding structure formed on the flexible encapsulating layer 3 can be adjusted to improve the haptic feedback effect of the haptic enhancement mechanism, which will not be described herein again.

It should be noted that, in implementation, the magnetic member 4 may include two coils disposed oppositely and two coils disposed adjacently.

Optionally, the receiving slot 11 has a rectangular structure, the magnetic element 4 includes a first coil 411, a second coil 412, a third coil 413, and a fourth coil 414, and the first coil 411, the second coil 412, the third coil 413, and the fourth coil 414 are respectively disposed around the receiving slot 11 (for example, the first coil 411, the second coil 412, the third coil 413, and the fourth coil 414 are respectively disposed on 4 sidewalls of the receiving slot 11, or respectively disposed at 4 edges of the bottom of the receiving slot 11);

the first coil 411, the second coil 412, the third coil 413 and the fourth coil 414 are enclosed to form a deformation area 20, and the control unit controls at least one of the first coil 411, the second coil 412, the third coil 413 and the fourth coil 414 to generate a magnetic field, so that the magnetic fluid 2 in the deformation area 20 is deformed to push the flexible packaging layer 3 to deform.

In this embodiment, the first coil 411, the second coil 412, the third coil 413 and the fourth coil 414 are disposed end to end, and each coil is disposed parallel to one side of the accommodating slot 11 to form a deformation region 20 in the accommodating slot 11, wherein the magnetic fluid 2 is located in the deformation region 20, so that the magnetic fluid 2 can be driven to deform in various structures in the deformation region 20 by magnetic fields generated by 4 coils surrounding the magnetic fluid 2.

For example: as shown in fig. 4a, the control unit controls the first coil 411, the second coil 412, the third coil 413 and the fourth coil 414 to be simultaneously electrified, so that the magnetic fluid 2 is gathered at the center of the deformation zone 20; or

As shown in fig. 4b, the control unit controls the first coil 411, the second coil 412 and the third coil 413 to be energized simultaneously, and the fourth coil 414 to be de-energized, so that the magnetic fluid 2 is gathered at the edges of the deformation zone 20 close to the first coil 411, the second coil 412 and the third coil 413, and the volume of the magnetic fluid 2 is gradually increased in a direction away from the fourth coil 414; or

As shown in fig. 4c, the control unit controls the first coil 411 and the second coil 412 to be simultaneously energized, and the third coil 413 and the fourth coil 414 to be simultaneously de-energized, so that the magnetic fluid 2 is gathered at one corner of the deformation zone 20, and one corner of the deformation zone 20 is located between the first coil 411 and the second coil 412; or

As shown in fig. 4b, the control unit controls the first coil 411 to be energized, and the second coil 412, the third coil 413 and the fourth coil 414 to be de-energized simultaneously, so that the magnetic fluid 2 is gathered in the deformation region 20 near the edge of the first coil 411.

In practice, the above-mentioned manner of adjusting the operation mode of the magnetic member 4 by activating the coils (411 to 414) at different positions may be combined with the manner of adjusting the current magnitude and current direction of the coils (411 to 414) to realize the operation mode of the magnetic member 4.

The current direction of the coil is adjusted, so that the magnetic field direction of the magnetic part 4 can be changed, the stress direction of the magnetic fluid 2 is adjusted, and the position of the convex structure formed on the flexible packaging layer 3 can be changed; by adjusting the current of the coil, the magnetic field intensity of the magnetic part 4 can be changed, so that the stress of the magnetic fluid 2 is adjusted, and the protruding degree of the protruding structure formed on the flexible packaging layer 3 can be changed. Based on the change of the position and the protruding degree of the protruding structure, different tactile feedback can be realized.

In this embodiment, assuming that the receiving groove 11 has a rectangular frame structure, 4 sides of the receiving groove 11 may be respectively provided with one excitation coil, so that 4 excitation coils may be disposed around the magnetic fluid 2, and by activating part of the excitation coils, the operation mode of the haptic enhancement unit 100 may be switched. In implementation, the control unit may individually control the current magnitude and/or the current direction of each excitation coil 41 to control the touch enhancement unit 100 to switch between multiple working modes, wherein different touch senses can be generated by touching the touch enhancement unit 100 in different working modes, so as to form rich touch sense combinations, and meet the requirements of different application scenarios, thereby improving the performance of touch enhancement feedback.

Optionally, as shown in fig. 5, the haptic enhancement mechanism includes at least two haptic enhancement units 100, the main body portion 1 is made of a magnetic isolation material, and the main body portion 1 separates the at least two haptic enhancement units 100;

the control unit controls the energizing of the coil within each haptic enhancement unit 100 of the at least two haptic enhancement units 100, respectively.

In this embodiment, the control unit may control each haptic enhancement unit 100 individually, i.e. the same control unit may control different haptic enhancement units 100 in different operation modes, for example: controlling one of the haptic enhancement units 100 in the first operation mode and controlling the other haptic enhancement unit 100 in the second operation mode allows more accurate haptic feedback to be achieved by the plurality of haptic enhancement units 100 cooperating with each other.

Optionally, the magnetic element 4 comprises at least two coils (e.g. a first coil 411, a second coil 412, a third coil 413, and a fourth coil 414) arranged at intervals;

the touch enhancement unit 100 comprises N working modes, wherein the N working modes correspond to N coil working groups one by one, each coil working group comprises at least one electrified coil, and N is a positive integer;

the control unit is configured to activate a coil working group corresponding to a target working mode in the haptic enhancement unit 100, so that the haptic enhancement unit 100 works in the target working mode.

In this embodiment, the excitation coils 41 may be grouped, wherein each coil work group may include at least one energized coil. Thus, by associating the coil working groups with the working modes one by one, the control module only needs to activate the coil working group corresponding to the target working mode when controlling the haptic enhancement unit 100 to work in the target working mode.

Alternatively, as shown in fig. 2 for example, the operation mode of the haptic enhancement unit 100 may include the following modes:

the first mode is as follows: if the activated coil is used to generate a magnetic field for attracting the magnetic fluid 2, as shown in fig. 4a, when 4 coils (the first coil 411, the second coil 412, the third coil 413, and the fourth coil 414) are activated, the magnetic fluid 2 can be caused to flow toward the middle region of the housing tub 11.

And a second mode: when 3 coils (such as the first coil 411, the second coil 412 and the third coil 413) are activated, the magnetic fluid 2 can tend to form a U-shaped protruding structure as shown in fig. 4b, and it should be noted that, as shown in fig. 4b as an example, in the implementation, the control unit can also switch the non-activated coil to be the second coil 412 located at the upper side of the accommodating groove 11, the third coil 413 located at the right side of the accommodating groove 11 or the fourth coil 414 located at the lower side of the accommodating groove 11, so as to rotate the orientation of the U-shaped protruding structure formed by the magnetic fluid 2 by 90 °. That is, the second mode may specifically include 4 modes, which are not described in detail herein.

And a third mode: when only 2 adjacent coils (such as the first coil 411 and the second coil 412) are activated, the magnetic fluid 2 can tend to form a convex structure gathered at the top corner of the housing slot 11 as shown in fig. 4c, and it should be noted that, as shown in fig. 4c as an example, in implementation, the control unit can also switch the inactivated coils to be the second coil 412 and the third coil 413, the third coil 413 and the fourth coil 414 or the fourth coil 414 and the first coil 411 so as to make the convex structure formed by the magnetic fluid 2 rotate by 90 °. That is, the mode three may specifically include 4 types, which are not described in detail herein.

And a fourth mode: when only 1 coil (for example, the first coil 411) is activated, the magnetic fluid 2 can tend to form a protrusion structure gathered along one side of the receiving slot 11 as shown in fig. 4d, and it should be noted that, as shown in fig. 4d as an example, in the implementation, the control unit can also switch the activated coil to be the second coil 412, the third coil 413 or the fourth coil 414, so as to rotate the protrusion structure formed by the magnetic fluid 2 by 90 °. That is, the mode four may specifically include 4 types, which are not described in detail herein.

In summary, in the case that the magnetic member 4 includes 4 coils, the haptic enhancing unit 100 may have 13 operation modes. Of course, in practice, the haptic enhancement unit may include more (e.g., control coil generating a magnetic field that repels the magnetic fluid 2, etc.) or fewer modes of operation based on the adjustment of the control logic. In addition, in the implementation, the shape of the accommodating groove 11 is not limited to a quadrangle, but may be a pentagon, a hexagon, and the like, and the number of coils included in each accommodating groove 11 may also be adjusted, for example: one, 2, 3, 4, 5, 6, etc., the operation mode of the haptic enhancement unit 100 may be changed accordingly based on the shape of the receiving groove 11 and the adjustment of the number of coils included in each receiving groove 11, and is not limited in detail herein.

Optionally, as shown in fig. 1, the tactile sensation enhancing unit 100 may further include a wiring layer 5, the wiring layer 5 is disposed below the main body portion 1 (i.e. on the side away from the notch of the receiving slot 11), in an implementation, a circuit may be disposed on the wiring layer 5, so that the connection of the through hole 40 penetrating through the bottom of the receiving slot 11 can electrically connect each coil in the magnetic member 4 with the circuit on the wiring layer 5, and thus each coil can be electrically connected with the control unit, the power supply and the like through the wiring layer 5.

In one embodiment, the touch enhancement unit 100 may be disposed below the flexible display 200, so that when the upper surface of the touch enhancement unit 100 is deformed, the flexible display 200 attached to the flexible packaging layer 3 is deformed accordingly. In this way, a tactile sensation enhancement mechanism may be integrated on the display screen for tactile sensation enhancement feedback with the display screen.

In an implementation, the flexible display screen 200 may be a touch display screen, so that when a user touches the flexible display screen 200 to obtain a haptic feedback, the touch display screen may further obtain a position touched by the user, so as to determine a haptic enhancement content touched by the user, and form a haptic enhancement unit of the haptic enhancement content or a display content corresponding to the haptic enhancement content, so as to obtain a touch operation performed by the user, thereby implementing the corresponding haptic feedback. For example: under the condition that the touch display screen displays the characters, the touch enhancement mechanism can form corresponding braille in the position of each character, a user touches the braille to read, the electronic equipment can obtain the position touched by the user, and therefore the reading speed of the user is obtained, and therefore matching of character switching and the reading speed of the user is facilitated, or the braille formed by the touch enhancement mechanism is timely switched when the user reads the tail of the characters.

In practical applications, in addition to disposing the tactile sensation enhancing mechanism below the flexible display screen, the display screen and the tactile sensation enhancing mechanism may be disposed in different areas on the electronic device, so that the user performs visual feedback through the display screen and performs tactile feedback through the tactile sensation enhancing mechanism, which is not limited in this respect.

The embodiment of the present application further provides a tactile sensation enhancing method, which may be applied to the electronic device provided in the previous embodiment, and as shown in fig. 6, the tactile sensation enhancing method may include the following steps:

601, acquiring target work modes of a target touch enhancement unit and the target touch enhancement unit by a control unit;

step 602, the control unit controls the target tactile sensation enhancement units to work in the respective corresponding target work modes to form tactile sensation enhancement contents on the flexible packaging layer.

In an implementation, the control unit may determine the target operation mode of each of the target haptic sensation enhancing unit and the target haptic sensation enhancing unit according to the haptic feedback requirement, wherein the target haptic sensation enhancing unit may include one haptic sensation enhancing unit or at least two haptic sensation enhancing units, and when the target haptic sensation enhancing unit includes at least two haptic sensation enhancing units, the target operation mode of each haptic sensation enhancing unit may be the same or different.

In this way, when the control unit controls the target tactile sensation enhancing units to work in the corresponding target work modes, the haptic enhancement content for meeting the haptic feedback requirement can be formed through the haptic enhancement mechanism, such as: a three-dimensional icon is formed at a designated position, a section of braille is formed at a designated position, and the like.

Alternatively, the display screen and the tactile sensation enhancing mechanism of the electronic device may share one control unit, for example: the processor of the electronic device is shared, and the processor can also determine an area needing touch enhancement according to information such as display content of the display screen, user configuration and the like, determine respective target working modes of the touch enhancement units in the area needing touch enhancement, and control the touch enhancement units in the area needing touch enhancement to work according to the respective target working modes so as to realize corresponding touch feedback.

As an alternative embodiment, the control unit obtains the respective target operation modes of the target tactile sensation enhancing unit and the target tactile sensation enhancing unit, and includes:

the control unit acquires first information including: the display content of the flexible display screen and the display position of the display content;

the control unit determines a target touch sense enhancement unit and a target working mode of the target touch sense enhancement unit according to the first information, wherein the position of the target touch sense enhancement unit corresponds to the display position, and the target working mode of the target touch sense enhancement unit corresponds to the display content.

In an implementation, the content displayed on the flexible display screen may be any content such as characters, pictures, icons and the like, and after the control unit determines the respective target operating modes of the target tactile sensation enhancing unit and the target tactile sensation enhancing unit according to the first information, the control unit may control the target tactile sensation enhancing unit to operate in the respective target operating modes to form tactile sensation enhancing content such as braille corresponding to the characters, relief drawings corresponding to the pictures, and tactile sensations corresponding to the icons, so that the user may communicate the content displayed on the flexible display screen to the user in a tactile feedback manner by touching the tactile sensation enhancing content. For example: as shown in fig. 7, when the display content is the picture verification code, the electronic device may recognize the verification code in the picture and form braille of the verification code by means of tactile feedback.

It is worth mentioning that, in the related art, when the part of visually impaired consumers use the mobile phone to input the verification code in the scene as shown in fig. 7, the input assistance function of the mobile phone is required. The current mainstream auxiliary means are as follows: the function of assisting the user to input the correct verification code is achieved by means of enlarging fonts, adding voice assistants and the like, such as: the intelligent voice assistant automatically broadcasts the identification content by identifying the picture so as to guide the user to input correct information and complete the identity verification action.

For another example: in the verification scenario of the graph + position alignment class shown in fig. 8, the user is required to drag the slider to the designated area to complete the puzzle, and at this time, the voice assistant in the related art cannot effectively guide the user to complete the related operations. In the embodiment of the present application, the most familiar tactile manner of the visually impaired user can be used to assist the user in performing corresponding operations, such as: specific tactile feedback is formed on the slider and the designated area respectively, so that a user can know the positions of the slider and the designated area according to the assistance of tactile sense, and the slider is dragged to the designated area.

In this embodiment, the control unit is capable of forming a tactile sensation enhancement content corresponding to the display content at a corresponding position of the tactile sensation enhancement mechanism according to the display content of the flexible display screen and the display position of the display content to assist a user in recognizing the content displayed on the flexible display screen through tactile sensation and/or assist the user in operating the electronic device through tactile sensation.

In an embodiment, the target tactile sensation enhancing unit may be a tactile sensation enhancing unit directly facing a display position where a character is displayed. Of course, in the case where the number of the target tactile sensation enhancing units is small, the target tactile sensation enhancing units may display different braille characters by turns, for example: the target tactile sensation enhancing unit may include all the tactile sensation enhancing units in the tactile sensation enhancing mechanism by dividing a piece of text into M sections, M being an integer greater than 1, so that the target tactile sensation enhancing unit may round-stream the braille of each piece of text M times.

In the implementation, identification information (such as position information) of the touch sense enhancement units touched by the user can be acquired, when the user reads the braille formed by the target touch sense enhancement units in sequence, the speed of reading the braille by the user can be determined according to the change of the touch sense enhancement units touched by the user, and the speed of reading the braille by the user is matched according to the change; or determining whether the user reads the last braille according to the change of the touch sense enhancing unit touched by the user, thereby controlling the target touch sense enhancing unit to form the next section of braille when the user reads the last braille.

Optionally, the display content includes a preset icon;

the control unit determines a target touch enhancement unit according to the display position of the preset icon;

and the control unit determines respective target working modes of the target touch enhancement units according to the types of the preset icons.

In this embodiment, different tactile sense enhancement modes may be configured for different icons, so that when a certain icon is displayed on the display screen or a certain icon is displayed, the tactile sense enhancement unit for forming the tactile feedback of the icon can be determined according to the display position of each icon, for example: the tactile feedback of an icon is formed using a tactile sensation enhancing unit directly below the display position of the icon. Furthermore, the operation mode of the haptic enhancement unit forming the haptic feedback of each icon may also be determined according to the configured haptic enhancement mode of the icon.

For example: assume that the buttons of the music playing function are displayed on the display screen: play button, pause button, next song button. A first tactile key may be formed at the position where the play button is displayed by controlling the tactile sensation enhancing unit corresponding to the position where the play button is displayed to operate in the first operating mode; controlling the touch enhancement unit corresponding to the position where the pause button is displayed to work in a second working mode so as to form a second touch key at the position where the pause button is displayed; and controlling the touch enhancement unit corresponding to the position where the next song button is displayed to work in a third working mode so as to form a third touch key at the position where the next song button is displayed, so that the user can distinguish the function or type of each key through the touch of each key, thereby executing corresponding operation.

Optionally, the preset icon may further be associated with a respective key sound effect, a vibration mode, and the like, so that when the user touches the preset icon, the electronic device sends the key sound effect associated with the preset icon, or generates vibration associated with the preset icon, and an effect of prompting whether the actual operation of the user is matched with the operation that the user wants to execute or not through sound effect or vibration can be achieved, thereby improving user experience.

In implementation, in the process of touching the display screen by the user to obtain the tactile sensation, the user may close the touch function (for example, pressing a hardware button on the side or touching the display screen with two fingers) to close the touch function, and after the user has obtained the tactile feedback content, open the touch function to perform the touch operation, so that the probability of the occurrence of the wrong touch operation in the process of touching the display screen by the user to obtain the tactile sensation may be reduced.
