The Captiva Touch Light Curtain works in combination with Christie® Captiva Series’ built-in camera to allow users to interact with the image on the screen when used in front projection mode. Depending on the screen material, the audience can either use their fingers or a soft-tipped stylus (included). The Captiva Touch module quickly installs inside the edges of the white board or on the wall above the image. Requires installation of utility software and a USB connection between the source of the image and the projector.
