Device with braille display function and secure transaction system including it

technical field

The invention belongs to the technical field of safe transactions, and relates to a device with Braille display function and a safe transaction system including the same.

Background technique

Electro-tactile technology senses touch by sending digital information in the form of electric shocks. An electro-tactile panel formed by a conductive matrix is laid under the key device housing or screen, which can send electric shocks to simulate finger pressure. The pixels used by each node are similar to the pixels of a digital picture, which can be dynamically changed so that people can perceive the information that needs to be confirmed.

Now electrotactile technology has been applied in many fields, such as mobile phones and so on. However, there are no related products for displaying braille that blind people can recognize on safety devices such as keys that require information confirmation and wearable devices.

Contents of the invention

The primary purpose of the present invention is to provide a device with Braille display function, so as to solve the technical problem that traditional security products cannot be used by blind people.

To achieve this purpose, the present invention provides a device with a Braille display function, the device with a Braille display function includes a PCB board, an electric tactile panel welded on the PCB board, and a main control chip,

Under the control of the main control chip, the electro-tactile panel displays braille that can be recognized by the blind, so that the blind can read the information carried by the braille and instruct the blind to operate.

Further, the device with Braille display function also includes a security chip welded on the PCB, and the security chip encrypts the information carried by the Braille under the control of the main control chip and sends it to on the electrotactile panel.

Further, the components welded on the PCB board are connected to each other through wiring between the PCB boards, and information is transmitted and shared according to the bus.

Further, the Braille that the blind can recognize is to apply a voltage to each contact of the electro-tactile panel according to the compiling rules of Braille, so as to combine into a Braille voltage stimulus that the blind can feel, so that the blind can feel Different current information received.

Further, the information carried by the Braille is transaction-related information.

Further, the transaction-related information is transaction card number and/or transaction amount information.

The second purpose of the present invention is to provide a safe transaction system suitable for the blind, so as to solve the technical problem that the traditional safe transaction system cannot be used by the blind.

To achieve this purpose, the present invention provides a safe transaction system suitable for the blind, which includes the aforementioned device with Braille display function and a transaction-capable device connected with the device by wire or wirelessly.

Further, the wired connection is a USB connection.

Further, the wireless connection method is Bluetooth connection or WIFI connection.

Further, the said device that can be traded is a personal computer (including a desktop computer, a notebook computer), a smart phone or a tablet computer.

The technical effect of the present invention is that, by using the device with Braille display function and the secure transaction system including the device of the present invention, it is convenient for blind people to conduct transactions more safely. The device with Braille display function of the present invention is a safe, convenient, fast and beautiful electric tactile panel material, a safety product for blind people, it is simple, convenient and easy to design, can be designed into various shapes, and the cost is relatively low Low cost, easy to produce, and can solve the problem that traditional security products cannot be used by blind people.

detailed description

The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1-2, the exemplary device with Braille display function of the present invention is a key security product based on electrotactile technology, including an electrotactile panel 1, a main control chip 2, a security chip 3, and a PCB board 4. Wherein the electrotactile panel 1 , the main control chip 2 and the security chip 3 are all welded on the PCB 4 . They are connected to each other through three wires on the PCB board, and information is transmitted and shared according to the bus.

Under the control of the main control chip 2, the electro-tactile panel 1 displays braille that the blind can recognize, so that the blind can read the information carried by the braille (such as transaction-related information including transaction card number and transaction amount information), and instruct the blind to operate.

The security chip 3 encrypts the information carried in Braille under the control of the main control chip 2 and sends it to the electrotactile panel 1 .

The Braille that the blind can recognize is to apply a voltage to each contact of the electrotactile panel 1 according to the compilation rules of the Braille, so as to combine the Braille voltage stimulation that the blind can feel, and then make the different current information that the blind can feel.

The exemplary safe transaction system suitable for the blind of the present invention includes the aforementioned exemplary device with Braille display function of the present invention and a wired connection (such as USB connection) or a wireless connection (such as Bluetooth connection or WIFI connection) with the device. A personal computer (either a desktop computer or a laptop).

The safe transaction system applicable to the blind of the present invention carries out the principle of safe transaction as follows:

After the device with Braille display function of the present invention is connected with peripheral devices such as a computer, the device with Braille display function will interact with the software in the computer. When the software in the computer needs to transmit information (such as transaction card number, amount, etc.) Compile the rules to apply voltage, so as to form the Braille voltage stimulation that the blind can feel, so that the blind can feel the Braille composed of different currents on the electrotactile panel 1, so that the blind can read the same as normal people in the device with Braille display function important information. These important information are sent to the electric touch panel 1 after being encrypted by the security chip 3 . Since there is no sound etc. in this way, it is also very safe from a security point of view. Only the person concerned can feel the current change on the electric tactile panel 1 and read the specific information, and it will help the person to move safely in various environments. Use security products so that security products can truly protect the interests of blind users.
