The host provided by the embodiment of the invention can be an electronic product such as a notebook computer, a smart phone, a PAD (PAD application) and a desktop computer, and can realize communication with the keyboard device through Bluetooth on the electronic product or through wireless or wired networks such as WIFI (wireless fidelity), 2G/3G/4G/5G/local area network and the like; the communication module can be a wireless or wired network module such as Bluetooth or 2G/3G/4G/5G/LAN, or other communication modes known to those skilled in the art; if both left-handed and right-handed keyboard input devices are provided, they are preferably mirror images in terms of structure or method of use by the user; the detection module may be or include an ultrasonic sensor, an infrared sensor, a gyroscope, a bending sensor, and the like, and may be or include a detection method such as pressure or temperature. The present invention is not particularly limited thereto.
In one embodiment, as shown in FIG. 1, when the detection module detects that a finger of the user is at point A, i.e. the distance from point A to the point of the hand at O is (0, x)1]When the range is within, the detection result is 1; when the detection module detects that the finger of the user is at the point B, namely the distance from the point B to the point O on the hand is (x)1，x2]When the range is within, the detection result is a value of 2; when the detection module detects that the finger of the user is at the point C, namely the distance from the point C to the point O on the hand is larger than x2The detection result is a value of 3; if the finger of the user is at the point D and the detection module fails to detect, the detection result is a value of 4, which indicates that the finger is at the point DDoes not participate in inputting the literal symbol. In this case, the values 1, 2, 3, and 4 are different detection results, but only the values 1, 2, and 3 participate in inputting the text symbols, and the text symbols participating in inputting are generally not the same.
In an embodiment, as shown in fig. 2, when the detection module detects that the value of the ring finger position of the user is 3, i.e. corresponds to g in the graph (e.g. the value corresponds to ch when the value is 2, and corresponds to j when the value is 2), if the values of other fingers are all 4, the processor processes the ring finger position into g according to a preset rule, and sends the processing result to the host through the communication module, so as to realize the input of (the corresponding chinese character of) the text symbol g; when the detection module detects that the value of the ring finger position of the user is 3, namely g in the corresponding graph, and simultaneously detects that the value of the index finger position of the user is 2, namely ua in the corresponding graph, and the values of other fingers are 4, the processor processes the result to gua according to a preset rule, and sends the processing result to the host through the communication module, so as to realize the input of (the corresponding Chinese character of) the character symbol gua; when the detection module detects that the value of the ring finger position of the user is 3, namely g in the corresponding graph, and simultaneously detects that the value of the index finger position of the user is 2, namely ua in the corresponding graph, and also detects that the value of the index finger position of the user is 2, namely-ng in the corresponding graph, and the values of other fingers are 4, the processor processes the ring finger position into the guang according to the preset rule, and sends the processing result to the host through the communication module, so that the input of (the corresponding Chinese character of) the character symbol guang is realized.
It is emphasized that in one embodiment, the value of the thumb or index finger may also be derived from the distance from at least two positions to the thumb or index finger, as shown in fig. 3, and the value of 2, which corresponds to-ng in the graph, is detected and finally determined for the position of the index finger of the user, which may be determined from the distance from three positions on the hand to the index finger. In addition, the distance can be calculated by referring to the included angle formed by at least two distances. The final result of the judgment may occur in the distance judgment module or in the processor, which is not limited in the present application.
As can be seen from the above explanation of fig. 1, 2, and 3, by detecting the distance between at least one position on the finger and the finger of the user, it is determined which fingers of the user are to participate in inputting the text symbols, and it is determined which symbols are to participate in inputting, so that the processing is performed according to the preset rule to realize the inputting of the text symbols.
Similarly, the detection modules of the above embodiments may also be used to detect the bending degree of several fingers of the user, so as to determine the character symbol to be implemented according to different values.
The above embodiments may also combine the functions of distance detection and bending degree detection to make more effective determination.
Optionally, in the keyboard device provided in the embodiment of the present invention, the detection module is configured to detect a touch and/or a movement between a plurality of fingers of a user and at least one position on a hand, and specifically, when the detection module detects that the plurality of fingers have the touch and/or the movement, the detection module determines whether a relative change of a displacement of the fingers within a certain time threshold is within a certain threshold range, so as to finally determine the touch and/or the movement between the fingers and the certain position on the hand.
As shown in FIG. 1, when the detection module detects that a certain finger of the user bends to the point A and the relative change of the finger displacement is within a certain threshold range (such as ≦ 5mm) within a certain time threshold (such as within 50 milliseconds), the distance from the point A to the point O on the hand is determined to be (0, x)1]Within the range, the detection result is a value of 1; when the detection module detects that the finger of the user bends to the point B and the relative change of the finger displacement is within a certain threshold range within a certain time threshold, the distance from the point B to the position of an O point on the hand is judged to be (x)1，x2]Within the range, the detection result is a value of 2; when the detection module detects that the finger of the user is bent to point C andwhen the relative change of the finger displacement is within a certain threshold range within a certain time threshold, judging that the distance from the point C to the point O on the hand is larger than x2The detection result is a value of 3; if the finger of the user bends to the point D and the detection module fails to detect, the detection result is a value of 4, which indicates that the finger does not participate in inputting the text symbol. Therefore, the accuracy of distance judgment can be improved.
Optionally, the detection module may be further configured to detect whether the user's finger has a touch action, and send a detection result to the processor. At this time, the processor can finally judge the distance between the finger and a certain position on the hand by combining other detection results sent by the detection module at the same time, so that the detection results are processed according to a budget rule, and the processing results are sent to the host through the communication module, so that the input of character symbols is realized.
The device can also comprise a plurality of touch pads for detecting the distance and/or the moving distance of the fingers of the user and sending the detection result to the processor. The touch pad can be used for measuring the distance and/or the moving distance when fingers touch, sense light, sense heat and the like on the touch pad, and the soft and hard media, the shape and the form of the touch pad are not limited.

detecting the distance and/or the moving distance between a plurality of fingers of the user and at least one position on the hand, and/or detecting the bending degree of the plurality of fingers of the user to obtain a detection result;
receiving the detection result and processing according to a budget rule;
sending the processing result to the host to realize the input of the character symbol;
the preset rule is that all the detection results are used for composing letters or syllables of a certain language at a certain time, or a part of the detection results are used for composing consonants/initials of a certain language at a certain time, and the other part of the detection results are used for composing vowels/finals of the language, so that the characters of the language are input.
Optionally, in the above method, "detecting a distance and/or a moving distance between a plurality of fingers of the user and at least one position on the hand" may specifically be that, when a touch and/or a displacement motion of the plurality of fingers is detected, it is determined whether a relative change of a displacement of the fingers within a certain time threshold is within a certain threshold range, so as to finally determine a distance between the fingers and a certain position on the hand.
