An audio-haptic feedbacks for enhancing user experience in mobile devices

We introduce a haptic library that creates tactile feedback by analyzing audio data. Because the proposed haptic library uses audio signal of application to make tactile feedback, it doesn't need to modify application. Also, user can select a particular audio frequency band from multiple audio sources with haptic profiles; then only selected audio can be converted to the tactile feedback. We designed 4 haptic profiles for specific tactile effects. Finally, application examples of applying the haptic library were introduced.
