Usage example of Handwriting Extraction in the classroom
User benefits
Using the Handwriting Extraction application (REA-L0100) makes it possible to extract
text and drawings from the white board or blackboard for real-time output as video.
Extracted text and drawings are displayed on top of the footage of the lecturer,
making it possible for the class to always view both the lecturer and what is written on
the board. Students can catch every detail of the lecturer’s face, gestures, and
explanations, simultaneously viewing both the lecturer as they speak and the content
on the board, which is usually hidden as it is being written. This leads to greater
understanding of and satisfaction with lectures. The system improves real-time video
viewing quality in large classrooms and remote classes, and makes it possible to easily
create appealing lecture content.
Features
Extract text and images from a white board or blackboard so that they are visible in front of the lecturer.
Adjustable transparency of the image of the teacher standing in front of the white board or blackboard.
The contents written on the board can be saved in JPEG format using the one-shot log function.
Streaming distribution is supported, in addition to HDMI output.
Can be used together with the PTZ Auto Tracking (REA-L0200) function by connecting two cameras.*
Supports extraction from a wide horizontal board or a raised board, and zoom display of the image
around the teacher.*
* Update the firmware to v4.00 or later before use.
