SCREENS Project
Basic functions of the SCREENS system
Screen transfer
The most important function of the SCREENS system is to transfer the teacher's screen image
to the students' screens. This function needs only one push of button. But it is also possible to
transfer any screen to any single workstation, group of workstations or the entire class. The
advantage of this system over a data projector is that the students can see all the details of the
instructed software in daylight, from anywhere in the classroom. The system also allows the
instructor to follow students’ progress from their own displays. To this end, the new
digital standard for flat panel displays (DVI) provides a significantly improved image resolution
and quality over the analogue display connector (VGA), which is becoming obsolete.
Scan
The teacher can scan student screens one by one or automatically in his/her own monitor. This
helps the teacher better to follow student’s progress during the lesson.
Remote control/Blackboard
Another useful function is that the instructor can take control over the USB-keyboard and the
USB-mouse of the computer he/she has selected. This feature enables the instructor at his/her
own computer to guide a student when it is needed. Blackboard feature makes it possible that
all other students can follow the quiding. Remote control also enables a teacher to prepare software
and files for all computers at the same time remotely before the lesson on his/her own computer.
Blank screens
The teacher can blank student screens if the teacher want to have attention preventing students
to work in their own workstations.
Info Screen/Call
The teacher can transfer his/her or anybody else's screen "for information". The student has so
possibility by the table unit switch between his/her own screen and the screen sent "for information".
The table unit gives also possibility to send a help call to the teacher.
Groups
The teacher can divide the class into groups as he/she wants and show each group the operation selected.
Data projector on/off
By one push of button in the User Panel, the teacher can switch the data projector on or off.
