Classification of touch input as being unintended or intended
First Claim
1. A device comprising:
- a touch surface configured to receive a plurality of inputs;
one or more processors communicatively coupled to the touch surface; and
memory storing instructions that, when executed by the one or more processors, configure the one or more processors to;
implement a first classifier configured to evaluate information associated with a first input and a second input to determine;
whether the second input corresponds to an intended touch input or an unintended touch input; and
an inter-arrival distance between a first position at which the first input arrives at the touch surface and a second position at which the second input arrives at the touch surface; and
based at least on the first classifier being unable to determine whether the second input corresponds to an intended touch input or an unintended touch input, implement at least one subsequent classifier configured to evaluate additional information to determine whether the second input corresponds to an intended touch input or an unintended touch input, wherein the additional information evaluated is associated with movement of the first input relative to movement of the second input.

Abstract
The techniques described herein implement a classification process to evaluate information associated with a tool input (e.g., from an input tool such as a pen or a stylus) and a user touch input (e.g., from a finger or a palm of a hand) to determine whether the user touch input is an intended or an unintended touch input. The information evaluated may be associated with an arrival of the tool input relative to an arrival of the user touch input. The information evaluated may also be associated with a movement of the tool input relative to a movement of the user touch input. In various implementations, the techniques may calculate an evaluation score and compare the evaluation score to a confidence classification threshold. If a confident classification cannot be achieved, the techniques further the classification process as more information associated with the inputs is received.
