For users to input data, it also includes keyboard input and output programs controlled by keyboard input. The key data classifier 132 determines whether the key is a long key or a short key according to the key state of the monitoring keyboard 131. When a key on the keyboard 131 is pressed or released, the keyboard 131 sends the key number (or key position) and the information of the pressed or released to the key data classifier 132, and the key data classifier 132 records the occurrence Time, and then use the difference between the time when the same button is pressed and released to get the duration of the button being pressed, and compare it with a preset threshold. If the duration of the button is longer than the threshold, it is a long button. Otherwise it is short. 13 and FIG. 14 respectively add a key data splitter 117, a voice unit 118 and a pre-recorded voice 120 to the keyboard key position unit 11 of FIG. 2 and FIG. 3, respectively, and the key data splitter 117 and voice respectively The unit 118, the key data converter 114, and the key data classifier 132 are electrically connected. The voice unit 118 is electrically connected with the pre-recorded voice 120. The key data shunt 117 receives the keyboard 131 from the key data classifier 132. The information of the number (or key position) of the pressed key and the key classification will convert the original input data converted from the key number by the key position data converter 114 to different processing methods according to the key classification. For long keys, The actual input data is set as the original input data after the conversion, and for the short key, the converted original input data is sent to the voice unit 118 for voice playback to inform the user of the character represented by the key yuan. The voice unit 118 is mainly used to receive the converted original input data and play the pre-recorded voice 120 of the original input data. The pre-recorded voice 120 is a set of voices recorded for each character represented by each key for The voice unit 118 plays a single character, and the voice unit 118 searches for the voice of the character of the original input data from the pre-recorded voice 120 and plays it. FIG. 16 is the execution flow of the embodiment of FIG. 13. First, step S402, the user presses a key on the keyboard 131 for input, and assigns the number (or key position) of the key and the information pressed or released to the key data classification. Device 132, step S403 determines the classification of the key by the key data classifier 132, and passes the key classification and key position of the key to the key data splitter 117, and then in step S404, the key data sorter 117 first receives the received key The bit string is transferred to the key data converter 114 to input the data and receive the converted data. In step S405, the key data shunt 117 determines whether the key is classified as a long key or a short key. If it is a short key, the key is converted. The input data is sent to the voice unit 118, and the corresponding character voice in the pre-recorded voice 120 is played. If the key is long, the actual input data is set as the converted input data. The functions of the long key and the short key are also interchangeable. For example, when the user presses a key with a long key, the voice of that key is played, and when the user presses a key with a short key, the A character represented by a key is used as a key input for the device.

In step S503, the user presses a key on the keyboard 131. The key number (or key position) and the information of pressing or releasing are given to the key data classifier 132. In step S504, the key data classifier 132 determines the classification of the key, and classifies the key and key of the key. The bits are transferred to the button data splitter 117, and then the step S505 button data splitter 117 first passes the received key string to the key data converter 114 to convert the input data and receive the converted data, and step S506 is the key data shunt 117 to determine whether the key is classified as a long key or a short key. If the key is short, the converted input data is sent to the voice unit 118, and the voice of the corresponding character in the pre-recorded voice 120 is played. If the key is long, the actual input data is set as the converted data. Enter information. The functions of the long key and the short key are also interchangeable. For example, when the user presses a key with a long key, the voice of that key is played, and when the user presses a key with a short key, the A character represented by a key is used as a key input for the device. Step S502 can also be executed after step S504. The architectures of Figures 13 and 14 are also suitable for generating keyboard key patterns in a random manner. First, a random key generator needs to be added, and all characters to appear on the keys for input are set in the random key generator. Memory, the random key generator generates, for each key, a corresponding character in a random but non-repeating manner from the memory of all the characters that are to appear on the key for input. The keyboard key patterns in the custom keyboard key pattern 121 and the pattern group 112 can be generated randomly.

The present invention can also use NFC (Near Field Communication) and RFID (Radio Frequency IDentification) technologies to improve the convenience of data input. Figures 18 and 20 are technologies for adding NFC with the framework of Figures 2 and 13, respectively. The NFC reader 115 and a style writer 116 are electrically connected to the NFC reader 115 and the custom keyboard key style 121, respectively.

An anti-peeping input device includes a keyboard key position unit (11) and an input unit (13). The input unit (13) includes a keyboard (131) and a key data classifier (132). The keyboard (131) is A key is not marked with a keyboard, touch interface, or input interface with keys that is associated with or sufficiently reminiscent of any character, symbol, or pattern of the character represented by the key. The key data classifier (132) is used to monitor the key press and release status of the keyboard (131). It is mainly based on the key status obtained by monitoring the keyboard (131) to determine whether the key is a long key or a short key. The key pattern unit (11) mainly converts the key string input by the input unit (13) into the input data according to the keyboard key pattern selected by the user, which includes a custom keyboard key pattern (121), One-key data converter (114), one-key data shunt (117), one voice unit (118), and one pre-recorded voice (120); the custom keyboard key style (121) is a set that can be used by the user Set keyboard key styles that can also be generated randomly; key positions The material converter (114) converts the key string or single-key key input by the input unit (13) into the actual input data according to the custom keyboard key style (121); the key data shunt (117) is Receives the key number and key classification information of the keyboard (131) from the key data classifier (132), and then passes the key number to the key data converter (114), and then receives the key position according to the custom keyboard The original input data converted by the pattern (121) will be processed differently according to the key classification. If it is a long key, the actual input data is set to be converted by the key data converter (114) from the number of the key. The original input data, if it is a short key, the previously converted original input data is sent to the voice unit (118) for voice playback; the functions of the aforementioned long and short keys can also be swapped; the voice unit (118) mainly In order to receive the converted original input data and play the corresponding character voice of the original input data in the pre-recorded voice (120); the pre-recorded voice (120) is a set of recordings for each character represented by each key voice. An anti-peeping input method includes the following steps. Step 1: The user does not mark any character, symbol, or pattern associated with the character represented by the key on the key or sufficient to remind others of the character represented by the key. Press the keys on the keyboard, touch interface or keyboard (131) with key input interface for input, and give the key number (or key position) and the information pressed or released to the key data classifier (132); Step 2: Determine the classification of the key for the key data classifier (132), and give the key classification and key position of the key to the key data shunt (117); Step 3: The key data shunt (117) The received key string is passed to the key data converter (114) to be converted into the input data and the converted data is received. Step 4: The key data shunt (117) determines whether the key is classified as a long key or a short key. If it is a short button, the converted input data is sent to the voice unit (118), and the corresponding character voice in the pre-recorded voice (120) is played, and if it is a long button, the actual input data is set. Input data for conversion Of the long and short keys and the function keys can also be replaced.
