A touch sensitive device for generating contextual haptic feedback comprising a touch sensitive member, a transducer mounted to the member, a processor comprising a control process and a further processing device connected to the processor, the further processing device being adapted to use a context map to enable signals to be provided to the transducer, whereby the transducer can couple vibrational energy to the touch sensitive member to provide haptic feedback.

Contextual haptic feedback

An inertial force transducer having an operative frequency range comprises a resonant element having a frequency distribution of modes in the operative frequency range of the transducer and a coupler for mounting the resonant element to a site to which force is to be applied. The resonant element is a piezoelectric device comprising a layer of piezoelectric material and a substrate layer on the layer of piezoelectric material. The substrate layer has a region extending beyond the piezoelectric layer, with the coupler mounted to the extended region whereby the low frequency performance of the transducer is extended.
