In some instances, well-known methods, schemes, elements and circuits have not been described in detail in order to emphasize the principles of the present application.

[0031] Figure 1 The structure diagram of the key for assisting the visually impaired person is shown. The key for assisting the visually impaired person according to the embodiment of the present application is used for the intelligent POS terminal, and comprises a base 100, a limiting piece 200 and a movable key 300. The base 100 has a connected state and a separated state. In the connected state, the base 100 is connected to the touch screen of the intelligent POS terminal. In the separated state, the base 100 is separated from the touch screen of the intelligent POS terminal. The limiting piece 200 is arranged on the base 100 according to a preset position. The movable key 300 is movably connected to the limiting piece 200. The movable key 300 comprises a clamping piece 310 and a physical key 320. In the use state, the limiting piece 200 and the clamping piece 310 are connected in cooperation, and the physical key 320 corresponds to the virtual key of the touch screen.

[0032] Specifically, the base 100 is connected to the touch screen of the intelligent POS terminal, and the visually impaired person can determine the key position through the sense of touch. The base 100 is movably connected to the touch screen, so that the visually impaired person can select whether to use the physical key 320 according to the need. The visually impaired person can easily switch the use mode in different environments or needs. The limiting piece 200 can ensure that the movable key 300 is in the correct position, provide reliable feedback, avoid misoperation and improve the accuracy of input. The physical existence of the movable key 300 can provide tactile feedback for the visually impaired person, helping the visually impaired person to better identify the touched key. Through the cooperation of the clamping piece 310 and the limiting piece 200, the visually impaired person can clearly perceive the position of each key. For different types of intelligent POS terminals, only corresponding adjustment according to the layout of the touch screen of the terminal is needed.

[0033] In some embodiments, the side of the base 100 away from the limiting piece 200 is provided with anti-slip material. The anti-slip material can effectively increase the friction between the base 100 and the touch screen, preventing the keyboard from sliding due to improper force during input. The anti-slip material has good wear resistance and durability, and can withstand long-term use without being easily worn out, ensuring the effectiveness and reliability of the keyboard in long-term use. In addition, the anti-slip material has the characteristics of easy cleaning, so that the visually impaired person can more conveniently maintain the cleanliness of the equipment during use, reducing the maintenance cost.

[0034] In some embodiments, the anti-slip material is silicone. The surface texture and elasticity of silicone make it have excellent friction when in contact with various surfaces, effectively preventing the keyboard from slipping during use, ensuring the stability of visually impaired people when inputting. Silicone has good wear resistance and can withstand long-term use without being easily damaged. In addition, silicone material has good waterproof and anti-fouling performance, making it easier for visually impaired people to clean and maintain the keyboard and keep it hygienic.

[0035] Figure 2 A structural schematic diagram of the movable key 300 of the embodiment of the present application is shown. In some embodiments, the clamping piece 310 includes a plug block 311 and a plurality of protrusions 312 uniformly distributed on the outer peripheral surface of the plug block 311 with the axis of the plug block 311 as the center. The plug block 311 provides a stable connection point, and the plug block 311 is made of high-strength material to ensure that it will not deform or be damaged during insertion and removal, thereby maintaining the reliability of the connection. The plurality of protrusions 312 are uniformly distributed on the outer peripheral surface of the plug block 311 to increase the friction and gripping force. During use, the protrusions 312 can effectively prevent the plug block 311 from slipping or loosening in the connection component, thereby ensuring the firmness of the connection.

[0036] In other embodiments, the protrusions 312 form a certain gap between the plug block 311 and the connection component, making it more smooth for visually impaired people during insertion and removal, which not only improves the operational convenience of visually impaired people, but also reduces the occurrence of misinsertion or jamming. The plug block 311 and the protrusions 312 are made of wear-resistant and impact-resistant materials to ensure the performance stability during long-term use.

[0037] In some embodiments, the cross section of the plug block 311 is circular, and the surface of the protrusion 312 connecting the plug block 311 is in close contact with the outer peripheral surface of the plug block 311. The circular structure can disperse stress when the plug block 311 is stressed, avoiding local stress concentration, thereby improving the overall durability and service life. The circular shape makes it easier to align and insert the plug block 311 during connection, which helps to simplify the operation process. The surface of the protrusion 312 connecting the plug block 311 is in close contact with the outer peripheral surface of the plug block 311, increasing the contact area and thereby improving the friction and stability of the connection. The presence of the protrusion 312 provides additional gripping force during connection, which can effectively prevent loosening caused by vibration or external force, thereby ensuring the safety of the connection.

[0038] In some embodiments, the limiting piece 200 is provided with a groove 210 matched with the shape of the clamping piece 310. In the use state, the plug-in block 311 and the protrusion 312 of the movable key 300 extend into the groove 210. The shape of the groove 210 is matched with the plug-in block 311 and the protrusion 312, which can realize accurate fitting and ensure that the two can be firmly combined when connected, avoiding loosening or displacement and preventing accidental falling or deviation during use. In the use state, the movable key 300 is combined with the groove 210, which helps the visually impaired to operate. Through the combined design of the movable key 300 and the groove 210, the visually impaired can easily complete the insertion and extraction action during use. The plug-in block 311 and the protrusion 312 form a stable connection in the groove 210, effectively improving the shock resistance and impact resistance of the overall structure.

[0039] In other embodiments, the clamping piece 310 and the limiting piece 200 can also adopt other limiting and matching modes, such as magnetic attraction, as long as the connection effect of the two can be realized, which will not be described in detail here.

[0040] In some embodiments, the movable key 300 further includes a connecting plate 330, and the clamping piece 310 and the physical key 320 are respectively arranged on opposite sides of the connecting plate 330. The use of the connecting plate 330 can enhance the stability of the overall structure and ensure that the clamping piece 310 and the physical key 320 do not interfere with each other during operation. The clamping piece 310 and the physical key 320 are arranged on the two sides of the connecting plate 330, so that the visually impaired can use different gestures or fingers more naturally during operation. The arrangement of the physical key 320 and the clamping piece 310 makes each function area more clear, and the visually impaired can easily identify the keys of different functions, thereby reducing the risk of misoperation.

[0041] In some embodiments, the physical key 320 is a protrusion 312 arranged on the connecting plate 330. The protrusion 312 of the physical key 320 is more prominent than the flat button, and the visually impaired can more easily identify and locate when touching. The protrusion 312 of the physical key 320 can effectively reduce the possibility of accidental touch, especially during device use, the visually impaired accidentally touch other areas, and it is not easy to accidentally activate.

[0042] In some embodiments, the movable key 300 in the use state, the physical key 320 one-to-one corresponds to the virtual key of the touch screen. The movable key includes a plurality of physical keys, and each physical key one-to-one corresponds to the virtual key of the touch screen. The visually impaired can directly operate through the physical key 320, which improves the operation efficiency.

[0043] In some other embodiments, the physical keys 320 can be configured to support multiple operation modes, such as short press, long press or combination press, to achieve multiple function control of the virtual keys, enhancing the flexibility of the device.

[0044] In some embodiments, the physical keys 320 block includes at least one of the following: a number key; or, a confirmation key; or, a back key. The number key is used to input numerical information, including keys from 0 to 9. The confirmation key is used to confirm the selection or input of the visually impaired person, to submit information, complete settings or perform specific operations. The visually impaired person can press the confirmation key to ensure that their input is accepted and processed. The back key allows the visually impaired person to easily return to the previous interface or undo the operation. By integrating these different types of keys together, the physical keys 320 block can meet multiple operation needs, improving the overall function of the device. The explicit function of each key enables the visually impaired person to intuitively understand how to operate the device, reducing the learning cost.
