Abstract
A method can include determining that a measured distance, of an object in contact with a touchscreen, from a sensor included in the touchscreen, is less than or equal to a first distance and equal to or greater than a second distance, based on determining that the measured distance of the object from the sensor is less than or equal to the first distance and equal to or greater than the second distance, providing haptic feedback as a function of the measured distance, the haptic feedback being greater for smaller measured distances; determining that the measured distance is less than the second distance; and in response to determining that the measured distance is less than the second distance, decreasing the haptic feedback.
