Abstract
A computing device includes a housing and a display assembly having a screen. The housing at least partially circumvents the screen so that the screen is viewable and a set of touch sensors are provided with the display assembly. A processor is provided within the housing to detect a plurality of interactions with the set of touch sensors. The processor further determines, based on the plurality of interactions, a presence of extraneous objects on a surface of the screen of the display assembly. More specifically, the processor may determine that the screen is wet if three or more interactions are detected, concurrently, via the set of touch sensors and/or a contact duration associated with each of the plurality of interactions exceeds a threshold duration.
