Afterglow makes it possible to use the laser pointer as a drawing tool allowing the user to draw directly on the screen. During a presentation it is possible to draw a line to emphasize a specific point and also to use the screen as a digital white board. Afterglow allows the user to change the color and thickness of the pen as well as type of pen giving the user more creative control over their drawings. The various pens such as the “Marker Pen” or the brush style “Samurai Pen” gives the user the ability to change the style to suit different situations.
