vTouch, an interactive whiteboard module compatible with ViewSonic LightStream® short-throw projectors*, offers educators an easy-to-use interactive projection solution. This USB powered module attaches easily to projectors and screens. With advanced laser curtain technology and auto-touch calibration, vTouch provides intuitive multi-touch capability. Support for up to 10 multi-touch users allows multiple students and/or instructors to work collaboratively in the classroom using their fingers or the included IR (Infrared) stylus. The bundled annotation software lets users write and draw on projected images, including office files and web pages. Teachers can also record their annotation steps and save these to share with students. Much more than a teaching aid, PJ-vTouch-10S immerses students in the learning process while enhancing interactivity and efficiency in the classroom environment. * Optional bundled with LightStream® short throw projector: PJD5353LS, PJD5553LWS, PJD6352LS, PJD6552LWS
