Systems and methods for providing localized tactile output and systems and methods for obtaining localized physical characteristic information are disclosed. An electronic device can include a friction transducer configured to augment and/or detect friction between a surface of an electronic device and an object in contact with that electronic device. The electronic device may also include a force transducer configured to detect the force with which an object contacts a display. The force transducer may also provide mechanical output. The electronic device can also include a thermal transducer to augment and/or detect the temperature of various locations on a display.
