Abstract: Method and apparatus for presenting audio and visual information to an audience by streaming, broadcast, live and recording presentations including a generally transparent pane having one end disposed proximate an end of a reflective pane to form an apex with an acute angle. In use an imaging device is disposed between the generally transparent pane and the reflective pane and oriented to image a reflection of the generally transparent pane off of the reflective pane. In operation a lecturer positions themselves in front of the generally transparent pane and performs an audio and visual presentation by writing written material on the surface of the generally transparent pane facing the lecturer. The imaging device, imaging a reflection of the generally transparent pane off the reflective pane, images a left-to-right reversal of the writing on the generally transparent pane thereby rendering it readable by a viewer.
Abstract: Method and apparatus for presenting audio and visual information to an audience by streaming, broadcast, live and recording presentations including a generally planar display screen, a light source directing light towards the display screen, a video camera oriented towards the display screen so as to image a lecturer through the display screen and a filter disposed between the display screen and the video camera. In one embodiment the light source emits light in predominately blue wavelengths and the filter blocks at least 85% of light at approximately the same wavelengths. Visual information may then be beneficially written by a lecturer on the display screen using a fluorescent marker pen. In operation an image output of the video camera is reversed in left-to-right orientation so that visual image information written by a lecturer onto the display screen is reversed from an orientation of this information viewed through the display screen.
