摘要:
A device includes a tip, a sensor, memory and a circuit. The tip is sensitive to contact pressure. The sensor detects the contact pressure. Memory stores at least one pre-defined first threshold and a pre-defined second threshold on the contact pressure. The first threshold defines tip state as one of a pen-up and a pen-down. Pressures below the first threshold defines pen-up and pressures above the first threshold define pen-down. The second threshold is below the first threshold. The circuit transmits in a hover transmission mode based on detecting pressures below the second threshold, switches to an writing transmission mode based on detecting a pressure at or above the second threshold and terminates the writing transmission mode based on detecting the pen-up status for a first pre-defined period. The writing transmission mode frame rate is higher than a hover transmission mode frame rate.
