Abstract: A method to correct a haptic output, the method including sending, at a device, a reference tactile signal to a haptic actuator and recording, using a sensor associated with the haptic actuator, an output signal from the haptic actuator. This output signal could be provided, along with the reference tactile signal to an engine at the device, which could be used to determine regions of perceptual distortion from the output signal and the reference tactile signal. Specifically, a perceptual similarity measure could be determined which could be used to generate an adapted signal to reduce and equalize the perceptual distortion, where the adapted signal could be provided to the haptic actuator to control adaptation or equalization of distortions.

Abstract: There is described a method performed by a computing device having first and second touch-sensitive user interfaces. According to this method, when a user input is applied to one of the first and second user interfaces, the computing device detects the user input and determines a force applied by the user input and a type of the user input. The computing device then determines whether to perform a function such as whether to display a virtual trackpad or a virtual keyboard, based on the force, the type of the user input, and a determination whether the user input is applied to a selected one of the first and second user interfaces.

Abstract: A method, a feedback-enabled device and a computer-readable memory are provided, for generating haptic feedback. The actuators of a tactile surface are vibrated for producing vibration bursts based on a sequence of an adaptive friction grain signal. The adaptive friction grain signal comprises a plurality of grains corresponding to the vibration bursts, each grain being defined by an amplitude. The adaptive friction grain signal has a grain density that is variable over the sequence.
