Abstract
This publication describes techniques for classification of user input using system contextual information for grip suppression on a mobile device (e.g., smartphone). In an example technique, a classification threshold is determined based on contextual information related to a current state of the mobile device and a heatmap is used to determine spatial features (e.g., amplitude, shape, size) relating to a user input on a touch panel of the mobile device. Based on a combination of the classification threshold and the spatial features, the user input is classified as intentional or unintentional. Using the techniques, unintentional user input, for example, those resulting from the user’s grip on the mobile device, may be filtered out while intentional user input is accepted as valid.
