Multi-transducer tactile user interface for electronic devices

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.
