  • Patent number: 10048758
    Abstract: A flexible device includes a bendable-foldable display that has bendable flaps connected by a hinge. The display has sensors for detecting a folding characteristic between the at least two flaps and for detecting a bending characteristic in at least one flap. The display has a haptic system with haptic output devices, where the haptic system receives input from the sensors indicating deformation of the bendable-foldable display device. A flexible device also includes bendable, foldable, or rollable displays that have sensors and actuators to augment user interaction with the device. Based on one or more measurements provided by the input, the haptic system interprets the input to determine deformation characteristics of the bendable-foldable display device. The haptic system generates haptic feedback based on the deformation characteristics.

  • Patent number: 10037081
    Abstract: Systems and methods for haptic fiddling are disclosed. In one embodiment, a sensor signal indicating an interaction with an electronic device is received by the electronic device. In response to receiving the sensor signal, the electronic device may output an output signal. The output signal may be output to a display, a haptic output device, an audio device, and/or another output device. The output signal can correspond to a modality. After outputting the output signal, another sensor signal indicating another interaction with the electronic device may be received by the electronic device. This interaction may be associated with the previously-received interaction. In response to receiving this interaction, the electronic device may output another output signal to the same output device(s) and/or different output device(s). The second output signal may correspond to one or more different modalities than the previous output signal.
