Providing enhanced presentation capabilities using a pointer implement. In an embodiment, a user operates a key on a pointer implement to cause the pointer implement to capture the display image on a screen and send the captured image frame to a digital processing system. The digital processing system examines the image frame to determine the location of a beam spot caused by the pointer implement, which can be used as a basis for several user features. For example, a user may cause the digital processing system to draw a line on the screen or use the pointer implement as a mouse as well.
