Cameramen often have a hard time filming class teaching. Passionate teachers speak with exaggerating gestures and walk along the platform, showing different PPT slides and asking questions. To accurately reproduce the teaching process, cameramen have to adjust the camera constantly to track the teacher’s movements, switch from the camera to VGA screen image, and give the answering students close-up shots in time. When the class is over, the cameraman would be totally worn out and the courseware video may not be in the best quality, and the biggest trouble is that with one or more cameramen around during the class, neither the teacher nor the students can focus on the regular teaching and learning process. Requiring no technicians, PowerCreator Graphic Position System makes sure that all the camera movements be done automatically.

PowerCreator Graphic Position System consists of two subsystems: Teacher tracking system and student positioning system. Teacher tracking system automatically calculates out the positions of teachers on the platform and informs the teacher camera to rotate; student positioning system automatically identifies the location of standing students and informs the student camera to give close-up shots.

Compared to similar products in the market, one of the most important features of PowerCreator Graphic Position System is that it will not loose the target, even when the teacher is running on the platform.

The traditional recording system has difficulty in filming students for the students need to press a trigger like a button, or a handy microphone, or a pressure sensor to instruct the camera, which greatly interrupts the normal teaching and learning process. Once the Graphic Position System is installed, no extra operation is required for teacher and students. As long as the student stands up, the system will recognize the movement and instruct the camera.

Infrared technology-based products are vulnerable to sunlight, heat sources and other factors, and ultrasonic technology-based products are harmful to human body for prolonged use. Graphic Position System adopts the image-recognition technology which is not easily affected by external factors and causes no harm to teachers and students.

Graphic Position System can work with just two (or more) cameras, one for the teacher and the other for the students.
