Equipment in the classroom
The Split Screen icon divides the computer screen into two images: the one on the left is the latest snapshot taken (or the latest snapshot chosen from the pull-out tab), and the image on the right is the live video from the visualiser's camera.
The snapshot (or “still image”) has this control under it:
The slider bar allows you to zoom in and out of the still image. There are three buttons to the right of the slider bar:
- leftmost button, “1:1”: makes the image to be displayed at maximum zoom
- second button: zooms the image all the way out
- third button is a toggle: click to display the still image over the whole screen; click again to shrink it back and show the split screen again.
Notice there is a vertical line between the two images. Drag the line left or right with the mouse to adjust the sizes of the two images relative to the whole screen
