Description

Technical Field

[0001] The present invention relates to the technical field of tactile simulation and reproduction, and in particular to a device and method for reproducing the tactile sensation of casual shoes and an online shopping method based on the tactile sensation reproduction. Background Art

[0002] The practical value of casual shoes is primarily evaluated based on three aspects: fit, material comfort, and aesthetics. With online shopping becoming the primary shopping method, consumers are increasingly demanding an enhanced online shopping experience. They are no longer satisfied with simply visually assessing the fit of casual shoes. There is an urgent need to utilize another form of human perception—tactile perception—to enable remote tactile interaction with products. Virtual reality (VR)-based tactile reproduction devices have become a research focus. VR is an emerging technology that uses computer computing and graphics processing to create simulation models and build three-dimensional virtual spaces. This allows for real-time 3D graphics generation, closely simulating real-world objects and environments. Users can interact with virtual objects in 3D space, experiencing an immersive experience. Using VR-based tactile reproduction devices, consumers can remotely perceive the tactile characteristics of products, enabling a more comprehensive understanding of product characteristics and enhancing the online shopping experience. Therefore, research on VR-based tactile reproduction devices is of great significance.

[0003] The national standard GB / T32436-2015 stipulates the shoe last fit evaluation method, including the test last requirements and the shoe last fit evaluation system, which mainly stipulates and calibrates the length, width, circumference and last body size of the main parts of the shoe last. At present, the main methods for reproducing the tactile sensation of objects at home and abroad include vibration method, electrostatic force method, air pressure film method, and multi-integration method. The vibration method reproduces the tactile sensation of objects by changing the amplitude and frequency of the vibration element. The amplitude and frequency correspond to the reproduction elements of the tactile sensation, namely the texture height and the element spacing, respectively. However, the reproduced tactile texture is relatively simple and mostly reproduces the rough feeling; the air pressure film method drives the drivers placed parallel to the tactile panel to vibrate at high frequency to form a layer of air pressure film between the finger and the tactile interaction panel, thereby reducing the friction coefficient between the finger and the tactile interaction panel to achieve tactile reproduction, but the reproduced tactile sensation is relatively vague; the electrostatic force method forms a flat capacitor structure through sliding between the human body and the contact surface. The conductive material inside the finger will induce an electric charge opposite to the AC signal, and the reproduced tactile sensation is adjusted by controlling the transient voltage of the AC signal applied by the electrode plate, but the stimulation range is small.

[0018] The second solution of the present invention is to provide a method for reproducing the touch of casual shoes. Based on the above-mentioned casual shoe touch reproduction device, the method is characterized in that the touch reproduction can achieve the reproduction of soft touch, rebound touch, elastic touch and refreshing touch, and specifically includes the following steps:

[0019] Step 1: Based on the known outer dimensions of the casual shoe, the softness, rebound, and freshness characteristics of the fabric, the movement distances of the piezoelectric inertial displacement stages required to reproduce the tightness and elasticity are set; the current intensity of the first electromagnetic device when reproducing the softness; the initial height of the lifting mechanism and the current intensity flowing through the second electromagnetic device when reproducing the rebound; and the air intake volume of the air source compression pump, the air extraction volume of the air source vacuum pump, and the current intensity flowing through the temperature-regulating fiber layer when reproducing the freshness.

[0020] Step 2: Turn on the power supply and supply power to the outside to drive the piezoelectric inertial displacement stage to adjust the position of each group of soft feeling reproduction matrix, and splice the set casual shoe outline with the soft feeling reproduction matrix, shape memory polymer film a and polyurethane rubber transition layer, adjust the initial height of each group of rebound feeling reproduction matrix through the lifting mechanism, form the casual shoe sole with the rebound feeling reproduction matrix and shape memory polymer film b, and form the reproduced casual shoe with the casual shoe outline and the casual shoe sole, and supply power to the first electromagnetic device, the second electromagnetic device and the conductive fiber through the monitor to generate a magnetic field change of corresponding intensity, and supply power to the air intake source compression pump and the air exhaust source vacuum pump through the flow controller to exchange the gas inside the casual shoe outline, and supply power to the temperature regulating fiber layer through the monitor to adjust the pore size of the temperature regulating fiber layer;

[0021] Step 3: The user puts his foot into the reproduced casual shoes, and each set of limiting rubber tubes gives the foot force tactile feedback to reproduce the sense of tightness; at the same time, the foot contacts the surface of the soft feeling reproduction matrix. As the foot continues to be inserted into the reproduced casual shoes, the contact area and contact force between the foot and the soft feeling reproduction matrix continue to increase, and the magnetorheological fluid a encapsulated in the interlayer formed by the neoprene membrane and the silicone shoe mold grid sleeve is squeezed outward, and the magnetic field intensity it is subjected to continues to increase, thereby changing the yield strength of the magnetorheological fluid a, and the dynamically changing soft feeling can be felt through the soft feeling reproduction matrix; the rebound tactile feeling is composed of the rebound feeling reproduction matrix, the elastic polymer The composite honeycomb and lifting mechanism are comprehensively reproduced. By controlling the current intensity flowing through the second electromagnetic device, the magnetic field strength generated by the coil is changed to adjust the yield strength of the magnetorheological fluid B in the neoprene tube. This works in conjunction with the height-adjustable lifting mechanism below the limit frame to reproduce different degrees of rebound feeling. The refreshing feeling is comprehensively reproduced by the air intake source compression pump, the air exhaust source vacuum pump, and the temperature-regulating fiber layer. The air intake volume of the air intake source compression pump and the air exhaust volume of the air exhaust source vacuum pump are controlled by a flow controller. The pore size of the temperature-regulating fiber layer is adjusted by controlling the current intensity flowing through the temperature-regulating fiber layer to reproduce the refreshing feeling of casual shoes.

[0022] Step 4: Monitor the changes in the pressure values collected by the thin film pressure sensor, and compare whether the tightness characteristic values provided by each group of limit rubber tubes at each position are consistent with the actual tightness characteristic values. If not, adjust the several groups of piezoelectric inertial displacement stages with errors to reposition them until the error between the reproduced tightness and the actual tightness is eliminated; use a monitor to monitor the average value of the change rate of the conductive fiber resistance value, and compare the softness characteristic value corresponding to the value with the softness characteristic value to be reproduced. If not, change the magnetic field strength generated by the first electromagnetic device until the error between the reproduced softness and the actual softness is eliminated; monitor the change rate of the pressure value collected by the pressure sensor, and compare the response value corresponding to the value. Whether the elastic feeling characteristic value is consistent with the real rebound feeling characteristic value; if not, change the current intensity flowing through the second electromagnetic device, thereby changing the magnetic field intensity generated by the coil, and at the same time adjust the initial height of each group of rebound feeling reproduction substrates through the lifting mechanism until the error between the reproduced rebound feeling and the real rebound feeling is eliminated; monitor the temperature measured by the temperature sensor and the reproduced internal and external pressure difference of the casual shoes measured by the two-way gas pressure sensor, and compare the corresponding refreshing feeling characteristic value with the refreshing feeling characteristic value to be reproduced. If not, change the air intake volume of the air source compression pump, the air extraction volume of the air source vacuum pump, and the current intensity flowing through the temperature regulating fiber layer until the error between the reproduced refreshing feeling and the real refreshing feeling is eliminated;

[0023] Through the real-time feedback and correction of the above touch control parameters, the comprehensive reproduction of the touch of casual shoes is achieved, and the dynamic reproduction of softness, elasticity, rebound and freshness with feedback and correction is achieved.

[0024] Optionally, the characteristic values of the tightness, softness, rebound and freshness are obtained by testing a casual shoe touch quantification device, and the relationship between the characteristic value of the tightness and the position of the limiting rubber tube is established through calculation or simulation, the relationship between the characteristic value of the softness and the current intensity passing through the first electromagnetic device is established, the relationship between the characteristic value of the rebound and the current intensity flowing through the second electromagnetic device and the initial height of the rebound reproduction matrix is established, and the relationship between the characteristic value of the freshness and the air intake of the air source compression pump, the air exhaust volume of the air source vacuum pump and the current intensity flowing through the temperature regulating fiber layer is established.

[0025] The third solution of the present invention is to provide a method for online shopping of casual shoes based on tactile reproduction, marking the characteristic values of tightness, softness, rebound and freshness on the online shopping interface, and the user performs tactile reproduction of the various tactile characteristic values based on the above-mentioned tactile reproduction device and the tactile reproduction method described in claims 8-9 to assist in the selection and decision-making of casual shoes; the various tactile characteristic values are simultaneously transmitted to the virtual reality system, and casual shoes corresponding to the various tactile characteristic values are constructed in the virtual reality environment. Through the tactile reproduction device and the virtual reality system, the touch and vision are simultaneously reproduced to the user, allowing the user to try on the casual shoes when shopping online and experience the on-site tactile and visual perception.

[0026] Compared with the existing technology, the present invention has the following advantages: by using the present invention, people can actively perceive the real sense of tightness, rebound, softness and freshness through the interaction of the reproduction device and virtual reality, rather than judging the touch of casual shoes through vision and object characteristics. The present invention can also realize remote perception of touch and be used to assist decision-making in online shopping. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the initial height of each group of rebound feeling reproduction substrates 19 is adjusted by the lifting mechanism 17 until the error between the reproduced rebound feeling and the actual rebound feeling is eliminated. The temperature change rate of the temperature sensor 37 and the air pressure difference between the inside and outside of the shoe measured by the bidirectional gas pressure sensor 8 are monitored, and the corresponding refreshing feeling characteristic value is compared with the refreshing feeling characteristic value to be reproduced. If they are inconsistent, the air intake volume 6 of the air source compression pump, the air extraction volume of the air source vacuum pump 7, and the current intensity flowing through the temperature-regulating fiber layer 39 are changed until the error between the reproduced refreshing feeling and the actual refreshing feeling is eliminated. Through the real-time feedback and correction of the above tactile control parameters, the comprehensive reproduction of the object's tactile feeling is achieved.

[0037] The present invention is further described below with reference to a specific embodiment.

[0038] Five typical samples with known tactile characteristic values were selected. The current intensity I1 passing through the first electromagnetic device required to reproduce their softness was calculated from the softness characteristic values. The current intensity I2 passing through the second electromagnetic device required to reproduce their rebound feeling and the initial height H of the elastic polymer honeycomb body were calculated from the rebound feeling characteristic values. The current intensity I3 passing through the temperature-regulating fiber layer required to reproduce their refreshing feeling and the air flow rate difference Q between the air intake volume of the air source compression pump and the air exhaust volume of the air exhaust source vacuum pump were calculated from the freshness characteristic values. The displacement D of the piezoelectric inertial displacement stage required to reproduce their looseness and tightness was calculated from the tightness characteristic values. The tactile characteristic values and control parameters of the samples are shown in Table 1.

[0040]

[0041] Turn on the power supply and supply power to the piezoelectric inertial displacement stage through the monitor, driving the limit rubber tube to move to the set position and adjust the outline size of the reproduced sports shoes. The power supply also supplies power to the lifting mechanism, driving the screw and the rebound sense reproduction base to rise and fall, simulating the streamline of the casual shoe sole. At the same time, the power supply provides the calculated current to each component through the monitor, so that each touch reproduction component produces a specified intensity of magnetic field change, surface state change, air flow change and temperature change. Then the user inserts the foot into the inner cavity of the shoe, and each sensor collects data and compares the reproduced tactile characteristic value with the real tactile characteristic value to see if it is consistent. If not, the control parameters are corrected and monitoring continues until the error between the reproduced tactile feeling felt by the user and the real tactile feeling is eliminated. After the feeling is completed, turn off the power and a simulation and reproduction is completed.

[0042] The above description is merely a description of preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in the specific structure are permitted. In short, all variations made within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
