Embodiment 1

[0076] see Figure 4 , Figure 4 It is a schematic flowchart of a dictation proficiency evaluation method disclosed in an embodiment of the present invention. in, Figure 4The described method for assessing dictation proficiency can be applied to the wearable device described above. As described above, the wearable device includes a smart host, the smart host is provided with a camera module on the opposite top side and bottom side respectively, and the smart host can be rotated to realize simultaneous adjustment of the two camera modules shooting direction. Such as Figure 4 As shown, the dictation proficiency assessment method may include the following steps:

[0077] 401. When playing the dictation content, the smart host controls any shooting module to shoot moving images of writing objects located in the writing area.

[0078] In the embodiment of the present invention, according to the foregoing, the wearer of the wearable device can adjust the angle of the smart h...

Embodiment 2

[0089] see Figure 5 , Figure 5 It is a schematic flowchart of another dictation proficiency evaluation method disclosed in the embodiment of the present invention. Such as Figure 5 As shown, the dictation proficiency assessment method may include the following steps:

[0090] 501. The smart host detects whether the wearing limb of the wearable device is the limb holding the pen. If yes, end this process. If not, go to step 502.

[0091] In the embodiment of the present invention, if the wearable device is worn on the limb holding the pen, the distance between the camera module and the writing object is relatively small, coupled with the limitation of the viewing range of the camera module, it is difficult to recognize the moving track of the writing object through the image; otherwise , if the wearable device is worn on another limb, the distance between the camera module and the writing object is more appropriate, and the moving track of the writing object can be recogn...

Embodiment 3

[0115] see Image 6 , Image 6 It is a schematic structural diagram of another wearable device disclosed in the embodiment of the present invention. Such as Image 6 As shown, the wearable device includes a smart host, and the opposite top and bottom sides of the smart host are respectively provided with a shooting module, and the smart host can be rotated to realize simultaneous adjustment of the shooting directions of the two shooting modules; as shown in FIG. Image 6 As shown, the smart host can include:

[0116] The control unit 601 is used to control any shooting module to shoot moving images of writing objects located in the writing area when the smart host plays the dictation content;

[0117] In the embodiment of the present invention, the writing object can be a hand or a pen holding a pen, which is not limited in this embodiment of the present invention;

[0118] The first detection unit 602 is used to track the moving track of the writing object according to th...

Abstract

A method for evaluating proficiency in dictation and a wearable device. The method is applied to a wearable device including a smart host. The opposite top and bottom sides of the smart host are respectively provided with a camera module. The smart host can be rotated to Realize simultaneous adjustment of shooting directions of two shooting modules, the method includes: when the smart host is playing dictation content, controlling any one shooting module to shoot moving images of writing objects located in the writing area; according to the above moving images, tracking Writing the moving track of the object; identifying pause points in the moving track, and determining part of the dictation content corresponding to the above-mentioned pause point played by the smart host as unskilled dictation content. By implementing the embodiment of the present invention, it is possible to identify the moving track of the writing object through the image, thereby identifying possible pauses in the writing process of the user, and then evaluating the user's proficiency in dictation content.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a dictation proficiency evaluation method and a wearable device. Background technique [0002] Dictation training is a kind of practice method that children often use when learning a language. At present, there are some electronic devices (such as tutoring machines, smart watches, etc.) that can assist children in dictation training on the market. These electronic devices can replace teachers or parents to read dictation content, so that children can practice dictation anytime and anywhere. [0003] However, in practice, it has been found that most of these electronic devices can only read out words mechanically, making it difficult for parents or teachers to observe children's performance in the dictation training process, making it difficult to evaluate children's proficiency in dictation content based on children's performance . Contents of the invention [0004]...
