Description

Technical Field

[0001] This utility model relates to the technical field of hand operation training tools for special education, specifically a hand positioning and guiding device for mouse operation training in special education. Background Technology

[0002] In information technology teaching scenarios for students with moderate to severe intellectual disabilities and accompanying physical disabilities, the mouse, as a core input device, directly impacts students' learning outcomes and class participation due to its ease of use. However, existing traditional mouse designs do not consider the specific physiological needs of these students, exhibiting significant technical shortcomings. On the one hand, these students generally have problems with abnormal muscle tone and weak motor coordination. Traditional mice do not have a hand fixation and guidance structure, which makes students hold them unsteadily and their hands tremble during operation. This leads to inaccurate cursor positioning and makes it impossible to efficiently complete basic operations such as clicking and dragging. On the other hand, traditional mouse buttons lack protective design, making it easy for students to accidentally press them due to unintentional touches. Furthermore, the lack of a suitable support structure can lead to wrist and finger muscle fatigue after prolonged use, further reducing operational efficiency.

[0003] Therefore, there is an urgent need for a mouse that can address the physiological characteristics of these students and solve the problem that existing mice cannot meet the needs of information technology courses for special groups. By using this specially designed mouse operation training hand positioning guide device with a guiding and protective structure, the stability of students' hand grip is improved, the cursor positioning is more accurate, the frequency of operation errors is reduced, and the degree of operation fatigue is reduced. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hand positioning and guidance device for mouse operation training in special education, so as to solve the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a hand positioning and guidance device for mouse operation training in special education, including a wrist rest, a guide cover, a button guide limiting plate, and a finger rest. The wrist rest has a guide cover at its arc-shaped front end. The guide cover has a button guide limiting plate located on the right side of the front center of the guide cover, which guides and ensures that the student's index and middle fingers are separated, ensuring that the right index finger controls the left mouse button and scroll wheel, and the middle finger controls the right mouse button. The front end of the wrist rest extends forward along either the left or right side of the guide cover to support the student's little finger and ring finger. The other side of the finger rest bends upward and extends to form a limiting baffle, which forms a semi-enclosed limiting structure for the little finger and ring finger, making the mouse grip more enveloping and helping the student hold the mouse for easy movement. The wrist rest, guide cover, button guide limit plate, finger rest, and limit baffle are integrally molded to form a mouse operation hand positioning guide structure; the bottom surface of the mouse operation hand positioning guide structure is detachably set on the mouse body through a connecting block.

[0006] Preferably, the guide cover is designed as an arc-shaped back shell structure that fits the back of the mouse body; the back of the guide cover is up to 14mm higher than the upper surface of the button in the mouse body, which is used to consciously raise the student's fingers by raising the back of the guide cover, while helping the student understand and raise the base of the finger, and preventing accidental pressing of the finger.

[0007] Preferably, the inner wall of the guide cover is provided with an integrated connecting block.

[0008] Preferably, the inner wall of the guide cover is provided with an integrated support block near the front end, and the bottom of the support block abuts against the upper surface of the mouse body 7 to support the raised guide cover.

[0009] Preferably, the wrist rest is located directly behind the mouse body to help the student's wrist and mouse keep in a straight line. While supporting the student's wrist, it can effectively help the student counteract hand tremors, thereby improving the student's control and accuracy in moving the mouse.

[0010] The beneficial effects of this utility model are as follows: The hand positioning and guidance device for special education mouse operation training integrates a finger button guidance structure, a wrist support guidance structure, a finger support limiting and protective structure, and an arc-shaped back shell grip guidance structure into one unit. It can effectively help students fix their finger positions, correct their grip posture, and effectively help students counteract hand tremors by supporting their wrists. This improves the grip stability of students' hands and the operational stability of mouse movement, thereby improving the accuracy of cursor positioning, reducing the frequency of operational errors, solving the problem that existing mice cannot meet the needs of special groups in information technology courses, reducing operational fatigue, and improving the learning effect of information technology courses.
