Abstract
The utility model provides a wireless sensing marking pen. At present, a teacher only can point at a power point (PPT) by using a stick or an infrared device when making a PPT presentation by using a computer and a projector, and cannot intuitively make and mark key points for students. The wireless sensing marking pen comprises a wireless sensing end, a connecting rod, a handheld end, a switch end, a switch, a wireless receiving end and a universal serial bus (USB) interface, wherein the wireless sensing end is nested with the connecting rod, and can be contracted into the connecting rod; the connecting rod is nested with the handheld end, and can be contracted into the handheld end; the handheld end is connected with the switch end; the switch is arranged in the center of the handheld end, and is connected with the wireless sensing end; and the wireless sensing end is connected with the wireless receiving end through radio waves. The teacher can conveniently and intuitively mark the key points for the students at any time in a class, so that PPT teaching quality is improved.
Description
Technical field
The utility model relates to the laser pen field, relates in particular to a kind of wireless sensing bow pen.
Background technology
Along with the development of computing machine and multimedia technology, lantern slide (PPT) technology is more and more universal, has replaced gradually blackboard.But.The teacher can only give directions with wooden stick or infrared ray on PPT when utilizing computer and projector to say PPT usually at present, can not propose main points to the student intuitively, marks emphasis.
The utility model content
The purpose of this utility model is the deficiency for existing laser pen, and a kind of wireless sensing bow pen is provided, so that the teacher is saying class hour with PPT, can rule at PPT at any time, improves the quality that the PPT pattern is given a lesson.To achieve these goals, technical solution adopted in the utility model is, a kind of wireless sensing bow pen, comprise wireless sensing end, connecting link, handheld terminal, switch terminals, switch, wireless interface receiving end, USB interface, wherein, the wireless sensing end is connected with connecting link is nested, and the wireless sensing end can take in the connecting link; Connecting link is connected with handheld terminal is nested, and connecting link can take in handheld terminal; Handheld terminal is connected with switch terminals; Switch is installed on the center of handheld terminal, and switch is connected with the wireless sensing end; The length summation of wireless sensing end, connecting link, handheld terminal, switch terminals is between 1-2 rice; The wireless sensing end is connected by radiowave with the wireless interface receiving end; USB interface is connected with computing machine.
A kind of wireless sensing bow pen that the utility model provides, when the lecturer wants when projection screen is rule, press the switch of switch terminals, the wireless sensing end can calculate the position of pen, give computing machine signal feedback by wireless interface receiving end and USB interface, computing machine sends mobile cursor or other corresponding instruction according to the signal of feedback.When the wireless sensing end when projection screen is rule, the wireless sensing end is experienced pressure, signal sends to computing machine, computing machine sends instruction and moves cursor and draw black line at the PPT file, projects on the screen, realizes the function of line.Can be at any time when the utility model makes things convenient for the teacher at school, mark emphasis to the classmate more intuitively, improve the quality that PPT gives a lesson.
