The Optoma ML Concept is a powerful standalone LED projector designed for the educational market. It incorporates a media player, a Microsoft Office viewer, and built-in speakers. The use of a touchpad simplifies the physical interface of the device. Settings and tuners are now appearing on the projected digital interface. Moreover, the touchpad and the MS Office viewer allow the teachers to project and to control presentations without the need of a mouse and a computer. They can simply save the lessons on a USB stick or a SD card, and they are ready to go. Wireless projections are also possible from any device equipped with a WiFi connexion (mobile phone, tablet, PC/Mac).
