Presentation remote features an easy-to-use design to eliminate the need to install any software. Virtual laser pointer, marker pen, and black/white screen modes are already built-in for quick, simple use. Virtual laser pointer and pen can be seen on multiple PowerPoint presentation screens simultaneously to ensure that everyone in the room and on the call can see the pointer. Intuitive controls include a larger concave forward button and smaller convex back button positioned next to each other as you would expect to find on a keyboard. This helps ensure that the buttons are easy to find simply by touch, even in a dark auditorium. Remote is perfect for conference rooms and auditoriums with more than one display screen, or online meetings with remote audiences using web meeting tools such as WebEx, GoToMeeting, Skype and join.me. Presentation remote is compatible with PowerPoint 2010 or later on Windows and PowerPoint version 16.09 or later on macOS.
