Title:
アクティブスタイラスとセンサコントローラとの間の双方向通信に供される方法およびアクティブスタイラス
Document Type and Number:
Japanese Patent JP7271770
Kind Code:
B2
Abstract:
A method is provided to interface an active stylus with a sensor controller, wherein the sensor controller is coupled to a sensor configured to receive input from the active stylus. In the method the sensor controller defines data frames consisting of more than one time slot usable for receiving packets from the stylus. The active stylus transmits, in response to a request from the sensor controller, a signal including stylus capability information. The sensor controller determines, based on the stylus capability information, a downlink time slot allocation for use by the active stylus to transmit packets to the sensor controller. The sensor controller transmits the downlink time slot allocation to the active stylus.
