In particular embodiments, an apparatus includes a single electrode configured to passively receive a charge displacement and a change in characteristics of electromagnetic signals in an environment. The apparatus further includes a touch sensor, coupled to the single electrode, configured to detect a first input based on the charge displacement, and a second input based on the change in characteristics of electromagnetic signals in the environment.

Interaction sensing

In particular embodiments, an apparatus includes an insulator coupled to one or more electrodes that are configured to passively sense charge displacement or a change in characteristics of electromagnetic signals in an environment.

In particular embodiments, a method includes receiving a signal from an electrode of a touch sensor that senses a charge displacement, based on the signal, in order to detect the contact or separation. The method further includes detecting a contact or separation input to the touch sensor.

The touch sensor is a touch sensor that senses changes in characteristics of the electromagnetic signal in an environment in order to detect the contact or the proximity.
