Abstract

Embodiments described herein relate to methods and apparatus for outputting a haptic signal to a haptic transducer. A method for triggering a haptic signal being output to a haptic transducer comprises receiving an audio signal for output through an audio output transducer; determining whether the audio signal comprises a haptic trigger based on an indication of a rate of change of an amplitude ofthe audio signal, and responsive to determining that the audio signal comprises a haptic trigger, triggering the haptic signal to be output to the haptic transducer.

Description

technical field [0001] Embodiments described herein relate to methods and apparatus for outputting haptic signals to a haptic transducer based on received audio signals output through a speaker. Background technique [0002] For some applications, it may be desirable to generate haptic effects on mobile devices as well as other devices such as smart home devices or user interfaces of vehicles. In some instances, it may be desirable for these haptic effects to be synchronized with specific audio events to enhance the user experience. In some cases (e.g., where audio source material (e.g., specific songs of a known genre) is predefined in the system), it is conceivable that storage and playback can be performed independently of the known audio being designed to A sequence of haptic events that is output along with the song. [0003] However, there may be instances of audio playback that are not of a predictable or predefined nature. For example, in a gaming application, the...
