Description

A kind of lantern slide remote control pen crossed

Technical field

This patent, which is related to educating demonstration equipment field, especially one kind, can cross lantern slide remote control pen.

Background technology

Nowadays, lantern slide remote control pen has been widely used in the multimedia presentation systems such as meeting, teaching, by magic lantern Piece remote control pen, speaker may exit off manipulates lantern slide around computer, so as to preferably interactive with audience；In tradition In the case of, for people when being taught or being given a lecture using lantern slide, lantern slide remote control pen cannot directly transfer the picture in lantern slide Function is labeled, it usually needs is gone in face of computer and is operated using mouse, often drags slow lecture speed in this way, beat The rhythm of broken lecture；Existing lantern slide remote control pen interactive system generally requires additional addition image and adopts there are still many defects Collect hardware, such as：Interactive lantern slide systematic research is mainly based upon using optical system in screen both at home and abroad at present Laser point be identified and synchronized again with computer mouse position, such as 104615283 A of Patent No. CN, a kind of remote control The method that pen interaction method is announced, hardware device needed for this scheme is more, if being carried out in occasions such as current school, meeting rooms Installation, then the manpower and materials cost needed for installation and replacement hardware is excessively high.

Invention content

The purpose of this patent is to provide a kind of lantern slide remote control pen crossed in view of the deficiencies of the prior art, in addition to Except the due part of lantern slide remote control pen, it is also in pen container and is connected to sensor assembly and message processing module, to true Determine the position of laser point on the screen, laser point and scribing line pointer can be made to connect by lower switch, final realize can be The target directly crossed using paintbrush function on lantern slide.

To achieve the above object, this patent uses following technical scheme.

A kind of lantern slide remote control pen crossed, it is characterized in that by：Laser designator（1）, power on light（2）, paintbrush Display lamp（3）, pen container（4）, page up key（5）, middle key（6）, Page Down key（7）, paintbrush switch（8）, power switch （9）, can be inserted into computer USB interface receiver（10）, 2.4G radio filmslides be remotely controlled pen module（Module has been embedded in remote control hair Emitter etc.）（11）, connecting line（12）, battery case（13）, sensor assembly（14）, message processing module（15）, projection screen （16）, initialization points（17）Composition；Sensor assembly is fastened in pen container, prevents sensor assembly from opposite transport occurring in pen container Data precision that is dynamic and influencing acquisition, the receiver that remote control pen passes through 2.4G wireless technologys and pluggable computer USB interface（10） Connection, as depicted in figs. 1 and 2；Laser designator（1）, power on light（2）, pen container（4）, page up key（5）, middle key （6）, Page Down key（7）, power switch（9）, can be inserted into computer USB interface receiver（10）, connecting line（12）And battery Box（13）It can regard the shared part of all lantern slide remote control pens as, and paintbrush display lamp（3）, paintbrush switch（8）Sensor die Block（14）And message processing module（15）It is the structure of invention content, this part body is parallel to the lantern slide of other types In the mechanism of remote control pen；2.4G radio filmslides are remotely controlled pen module（Module has been embedded in remote control transmitter etc.）（11）This portion The type according to other lantern slide remote control pens of separation structure is different, can be substituted for the lantern slide remote control pen module of other types, Its structure may be different.

Before every use, lantern slide remote control pen has the one side of laser lamp to be vertically close to projection screen（16）The lower-left arm of angle The initialization points of edge（17）On, and power switch is pressed, initialization is completed, lantern slide remote control pen is just with initialization points（17）For sky Between coordinate origin establish space coordinates, sensor assembly（14）Where measuring sensor assembly in this space coordinates The spatial position of point and lantern slide remote control pen and three angle data of space coordinates, these data can be used for calculating laser point and exist Projection screen（16）On position, as shown in Figure 3.

Sensor assembly in lantern slide remote control pen（14）GY953 or MPU9250 sensor assemblies can be used, they are all carried 3-axis acceleration sensor, three-axis gyroscope, three axle magnetometer, the data that they are directly exported generally have an ohm angle, three axis to add The initial data of velocity sensor, three-axis gyroscope and three axle magnetometer, the output of quaternary number, the also included sensor calibrations of GY953 Order, because there is magnetometer, can make course angle not drift about；The initial data that GY953 is obtained can be in message processing module（15）It is complete At following conversion regime：

Acceleration transducer（g）=acceleration initial data/16383；

Gyro sensor（Degrees second）=gyro raw data/16.4；

Magnetic field sensor（uT）=magnetic field initial data/6.7；

By sensor assembly obtain data by calculating can obtain sensor assembly point spatial position and Lantern slide remote control pen and three angle data of space coordinates, this just entirely defines lantern slide remote control pen in space coordinates Position and posture then can calculate the coordinate position of laser point on the projection screen by these data, meanwhile, Computer mouse position is synchronized with laser spot position；When paintbrush function to be enabled, paintbrush switch is clicked（8）, open Animation function moves laser spot position, projection screen by lantern slide remote control pen at this time（14）Laser point rail can be followed automatically Mark setting-out.

The advantageous effect of this patent is：

1. convenient for users to marks such as circle, pictures by lantern slide remote control pen on lantern slide during speech or teaching Note can use the multimedia efficient and continuity of speech or teaching process good in this way；

2. hardware device is simple, powerful, easy to operate, strong applicability；

3. being relative to the advantages of existing optical identification scheme：Sensor assembly gathered data is relied primarily on, therefore is had Have that equipment is small, simple installation, the advantages such as hardware cost is low.
