Embodiment Construction
[0040] In order to illustrate the embodiments and technical solutions of the present invention more clearly, the technical solutions of the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0041] Mathematics and other science subjects often require students to be able to master the use of auxiliary tools such as a half-circle ruler. However, when subject assignments are digitized, if students still use ordinary half-circle rulers to complete homework, there will be many difficulties. For example: when students are required to use a stylus to draw a right-angled triangle of a specif...

The present invention discloses an electronic semicircle ruler system and a working method thereof, and a component part of an electric semicircle ruler system. The system comprises an electromagnetism semicircle ruler and an electronic semicircle ruler and an electronic terminal; the electronic semicircle ruler includes a semicircular part, electromagnetism points are respectively arranged at two vertexes of the diameter of the part and are called as vertex electromagnetism points, and an electromagnetism point is arranged at the midpoint of the semicircle of the semicircular part and is called as a midpoint electromagnetism point; the electronic terminal is configured to induct the electromagnetism points of the electromagnetism semicircle ruler and determine the electronic semicircle ruler of the electromagnetism semicircle ruler with respect to the coordinate system of the electronic semicircle ruler system according to the position information of the electromagnetism points.
Description
technical field [0001] The invention relates to the technical field of educational informationization, in particular to an electronic semicircular ruler system, its working method and components. Background technique [0002] With the continuous development of education informatization, more and more schools have established information-based teaching systems. Usually, this type of teaching system includes three parts: a server (referred to as the server), a teacher client (referred to as the teacher) and a student client (referred to as the student), and they cooperate with each other to complete the teaching process in an informationized manner. Especially with the development of network technology and mobile terminal technology, more and more information-based teaching aids have been introduced into the classroom. [0003] The introduction of these auxiliary equipment has changed the traditional teaching mode. For example, the way teachers assign subject homework to stu...
