Problems solved by technology

However, for the existing virtual keyboard, only the physical keys of the traditional keyboard are virtualized, and the layout and key size design of the virtual keyboard still inherits the traditional keyboard, which is basically fixed after its production, and the customizability is low.
Due to the different hand sizes and typing habits of different users, this type of virtual keyboard does not make good use of the characteristics of no physical buttons, and the use experience in reality is not good and the efficiency is low.

Embodiment 1

[0065] An information input method based on the relative displacement of the fingers, the mapping rule is the mapping between the letter keys of the QWERTY full keyboard and the displacement of the fingers, such as figure 1 shown, including the following steps:

[0066] (1) Key position initialization: Touch the touch panel with fingers of both hands or one hand, the sensor senses the touch point, transmits the initial position information of the touch point to the processor, and the processor assigns the preset initial mapping key position;

[0067] (2) Button recognition: the sensor senses the displacement information of the finger at the initial position and transmits the displacement information to the processor, and the processor compares the displacement information with the preset threshold to determine the button information, and the processor transmits the identified button information to the host ;

[0068] (3) Input mode switching: switch the input mode through cus...

Embodiment 2

[0081] Based on Embodiment 1, using the present invention, the end point of one displacement can be made the starting point of the next displacement, that is, after a displacement operation, instead of choosing to return to the initial position, the button represented by the end position of this displacement As a new starting position button, and automatically call its corresponding mapping rules, it can optimize the operation of continuous button input. Take the continuous input of three letters of YHU as an example, the steps are as follows:

[0082] . Same as the steps in Example 1 .

[0083] . On the full QWERTY keyboard, the three letters of YHU are the input content of the right index finger. Therefore, after the right index finger completes the displacement operation of the Y key input in Example 1, you can choose not to return to the initial position immediately, and trigger Y at this time. The contact position of the key input will be regarded as a temporary di...

Embodiment 3

[0088] For users with incomplete or disabled limbs, taking single-finger operation as an example, the system defaults this finger as the right index finger.

[0089] When it is in the index finger mode, slide to the right. If the sliding distance is less than threshold 1, it will be recognized as switching to middle finger mode. If the sliding distance is greater than threshold 1 and less than threshold 2, it will be recognized as switching to ring finger mode. If the sliding distance is greater than threshold 2 and less than threshold 3, it will be recognized as switching to ring finger mode. It is recognized as switching to the pinky mode; sliding to the left is recognized as switching to the thumb mode.

[0090]Similarly, when it is in the middle finger mode, slide to the right, and the sliding distance is less than the threshold 1, it is recognized as switching to the ring finger mode, and the sliding distance is greater than the threshold 1 and less than the threshold 2, i...

Abstract

The invention provides an information input method based in fingering identification. The method comprises the following steps: I, input initialization: trigging a fingering identification device by alimb, wherein the fingering identification device distributes a preset mapping rule; II, fingering identification: identifying a limb fingering by means of the fingering identification device and transmitting the fingering information to a host computer; and III, input mode switching: switching the input modes by means of the limb fingering or other limb operations. A device by adopting the method comprises the fingering identification device, the host computer and a power supply, wherein the fingering identification device is provided with a sensor and a processor, and the sensor is connected to the processor; the sensor senses the initial position of the limb and the shift of the limb; the processor receiving the initial position information of the sensor distributes the pre-set mappingrule, and the processor receives and identifies the limb shift information of the sensor and transmits the same to the host computer. The method and device provided by the invention have the advantage of button input in any position of a specified input region, is more intelligent and rapid to use anytime and anywhere, and enhances the satisfaction and comfort level of the user.

Description

technical field [0001] The invention relates to the technical field of virtual keyboards, in particular to an information input method and device based on fingering recognition mainly suitable for touch typists. Background technique [0002] In the existing traditional physical keyboard, the keys occupy an absolute position in the physical space, and the user clicks and presses the space. In fact, there is no logical or physical connection between the input of information and the operation behavior of an object at an absolute position in space, that is, the traditional keyboard operation method has a high degree of information redundancy. Moreover, the number of keys and the key layout of the physical keyboard are basically fixed after its production, and the customizability is low, and the cost of customizing the key layout is high. [0003] In order to overcome the shortcomings of traditional ordinary keyboards that are bulky and inconvenient to carry, virtual keyboards e...
