Abstract: A wireless hands-free pointer system includes a wearable unit and a base station. The wearable unit includes a head-mountable portion and a neck-mountable portion. The head-mountable portion includes an inertial measurement unit to detect movements of the head of a wearer. The neck-mountable portion includes a power supply, a microcontroller, and a wireless transmitter module and is formed to allow wearing by draping it about a wearer's neck to rest on their shoulders. The head-mountable portion is electrically coupled to the neck-mountable portion to receive power from the power supply. The head-mountable portion is also communicatively coupled to the neck-mountable portion to transmit detected movements of the head of a wearer to the microcontroller for determining position data for transmission to the base station using the wireless transmitter module. The base includes a wireless receiver module to receiving position data and can communicate the position data to a processing unit.
