Summary:Methods for uplink-based zero activation force are performed by systems and devices. A touch instrument interfaces with a touch device, and includes antennas that receive communication signals from the touch device. The touch instrument also includes a processing circuit that is electrically coupled to the antennas. The processing circuit determines an orientation of the touch instrument with respect to the touch device. A distance between the touch device and the touch instrument is then determined based on the orientation and a communication signal from the touch device received by the antennas, and an activation command is generated when the distance indicates a touch/contact. The activation command, transmitted to the touch device, causes the touch device to perform an inking operation. When the distance determined indicates a hover, and not touching/contact, a deactivation command is generated. Distance is also determined based on touch instrument orientation.
