Abstract: Link pencils, pens, or other writing utensils provide an improved method of discretely signaling special needs students in a class room setting. The invention utilizes radio frequency communication by using a transmitting device located inside of a writing utensil pencil that talks to a receiving device located inside a separate writing utensil. Once installed, there is no visible way to distinguish the modified pencils from ordinary pencils. The pencil containing the transmitting device is used by an instructor. The pencil containing the receiving device, which in some embodiments may be a transceiver such as a Bluetooth™ transceiver but without input to transmit a user controlled signal, is meant to be used by a student. When the instructor pushes down on the eraser or end of the writing utensil containing the transmitting device, the device containing the receiving device vibrates or emits light. This signals the student to pay attention.
