Abstract
A system includes a flexible display configured to display an image and a sensor connected to the flexible display. The sensor is configured to sense an amount of flexure of the flexible display. A haptic output device is connected to the flexible display and is configured to change a resistance to movement of a first portion of the flexible display relative to a second portion of the flexible display upon receipt of a haptic control signal. The system includes a processor in signal communication with the flexible display, the sensor and the haptic output device. The processor is configured to receive an output signal from the sensor based on the amount of flexure and generate the haptic control signal based on the output signal from the sensor.
