High-definition blackboard

摘要

A high-definition blackboard comprises a tablet-style computer as large as a standard classroom blackboard or dry-erase board, with Universal Service Bus (USB) ports, touch-screen capability, WiFi connectivity to the Internet, an internal disc drive which accommodates DVDs and CD-ROMs, speakers, and a webcam. A multi-purpose pen is provided which may be used as a laser pointer and a wireless mouse, and also serves as a pen for drawing or writing on the visual display of the device, in a manner similar to a conventional blackboard or dry-erase board. Due to the touch-screen capability, the user's bare hand will erase marks made with the pen. The pen may be used to access a digital keyboard which is displayed on the visual display, and may be used to access the Internet or operate conventional programs such as Microsoft® Word®. E-mails may be accessed, typed, and sent, and databases may be accessed, using the digital keyboard.
