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.
