Wearable devices can be generally characterized as body-worn and/or body-associated devices. Capacitive sensing approaches find use in wearable devices as a means of user input. Typically, a surface, such as an enclosure or housing, of the wearable device is made touch-sensitive via capacitive sensing for purposes of receiving user input.
The use of a large, touch-sensitive casing, however, minimizes the space available on the surface/exterior of the device to accommodate other aspects of device operation, such as, for example, an antenna. Antennas are a typical feature/requirement of wearable devices for wireless communication with external devices. While one solution could be to internalize the antenna into the body of the device, a conductive housing can substantially block/hinder the wireless signal from the antenna.
There is hence an unmet need to improve use of the conductive housing of a wearable device for different aspects of device operation.

In some embodiments, by selectively providing the first circuit 120A and the second circuit 120B access to the housing, the housing 110 can be alternately employed for capacitive touch input and for radio frequency transmission and/or reception. In some embodiments, by operating the housing 110 in the first configuration, the housing 110 can be employed as a capacitive touch circuit.
