Abstract
A method for identifying an error in a tip status indication from a stylus includes detecting input from a stylus with a digitizer sensor via an electrostatic (ES) wireless communication channel established between said stylus and said digitizer sensor. An indication of a tip status is received from the stylus, indicating whether the tip status is in hover or touch. The tip status is verified based on input detected with the digitizer sensor. When an error is identified in the tip status indication, a notification of the error is sent.
Claims20
A method comprising:
- detecting input from a stylus with a digitizer sensor via an electrostatic (ES) wireless communication channel established between said stylus and said digitizer sensor;
- receiving an indication of a tip status from the stylus, wherein the tip status is hover or touch;
- verifying the tip status based on the input detected with the digitizer sensor;
- identifying an error in the indication based on the verifying;
- and
- sending a notification of the error.
3 more elements
A device comprising:
- a digitizer sensor configured to detect input from a stylus;
- and
- a circuit configured to execute code instructions for:
- receiving an indication of a tip status from the stylus, wherein the tip status is hover or touch;
- verifying the tip status based on input detected by said digitizer sensor;
- identifying an error in the indication based on the verifying;
- and
- sending a notification of the error.
5 more elements
A stylus comprising:
- a tip status detector adapted to detect a tip status of said stylus, wherein the tip status is hover or touch;
- a modem associated with said tip status detector, adapted to modulate a signal with said tip status and to demodulate a received wireless signal to obtain a notification of an error in tip status;
- and
- a calibrator associated with said modem and said tip status detector, adapted to recalibrate said tip in response to said notification.
