Microsoft patents smarter pen data sending to save battery
Microsoft has been granted a patent for a system that predicts how a digital pen will move before the data is sent to the computer. Instead of sending every tiny movement, the system only sends updates when the actual pen position differs significantly from the predicted path, reducing the amount of data transferred.
In the filing’s own words
Predictive reporting of digital inking data is disclosed herein. An inking input predictor is employed on both a digitizer and a host computer. Reports are sent when the error between a predicted and an actual report exceeds a threshold. The predictive reporting of inking data reduces the number of reports sent by the digitizer to the host computer. Predictions may be made by prediction models, such as polynomial regression, Fourier series, and/or user-defined models. Models may be selected based on one or more conditions, providing adaptability to different input data types and user requirements.
What exactly they claim (claim 1)
1. A system, comprising: a digitizer configured to generate inking data representative of detected input operations performed in a user input area displayed by a host computing device; and a predictive reporter comprising: a predictor configured to generate inking data representative of predicted input operations predicted to be performed in the user input area based at least on inking data generated by the digitizer representative of previously detected input operations in the user input area; a detector configured to determine an error between the inking data representative of a detected input operation and the inking data representative of a predicted input operation; and a report generator configured to provide a report associated with the detected input operation to the host computing device in response to the error exceeding a threshold, wherein the threshold is adjustable based on a power condition of the host computing device.
