Η company Dell has built a touch screen capable of standing as a blackboard in a school or conference room.
Forget the blackboards in the classroom. OR Dell released an 70-inch touchscreen, the C7017T model, designed to replace interactive boards in schools and meeting rooms.
The device has a resolution of 1080p and can receive commands and from the ten fingers of a user but also from two special pennies. It's much more compact than Microsoft's 84-inch Surface Hub
Η price hers is $5000 and is probably high enough for a typical public school budget.
