Various aspects of the present disclosure generally relate to control of a user device under a wet condition. In some aspects, a user device may determine whether the user device is operating under a wet condition; select, based at least in part on whether the user device is operating under the wet condition, a set of input components to control the user device, wherein the set of input components is selected from a plurality of different sets of input components; and configure a user interface of the user device according to the set of input components. Numerous other aspects are provided.

Control of a user device under wet conditions

An apparatus configured to determine an approximate position of an object utilizing mutual-capacitance sensing capabilities during a first mode of operation and determining one or more attributes of the object utilizing self-capacitance sensing capabilities during a second mode of operation is disclosed. The apparatus includes a touch panel controller configured to operatively couple to a touch panel sensor. The touch panel sensor includes a plurality of drive electrodes and at least one sense electrode. A plurality of nodes are formed at the intersections of the plurality of drive electrodes and the at least one sense electrode. The touch panel controller is configured to determine an approximate position of an object performing a touch event over the touch panel sensor during the first mode of operation and to determine one or more attributes of the object during the second mode of operation.

Touch panel sensor having dual-mode capacitive sensing for detecting an object

A capacitive touch panel is tested for the presence or absence of short and open circuits in drive and sense lines without the use of a tool that touches the surface of the panel. During a first stage of testing, drive lines of the touch panel are sequentially driven while the remaining drive lines are floated. Sense lines are read to indicate whether a driven drive line is shorted to an adjacent drive line, an open circuit, or coupled to a sense line that is an open circuit. During a second stage of testing, drive lines are driven while alternate sense lines are floated or enabled. The signals on the enabled sense lines are acquired to indicate whether the enabled sense lines are shorted to adjacent sense lines. This second stage can be repeated, switching the roles of the sense lines, to determine the locations of short and/or open circuits.
