Description Enhancing inclusiveness in music fruition entails devising alternative sensory involvement for users with visual or auditory impairments. One possible option is the exploitation of tactile feedback, e.g., by means of vibrating surfaces that can help creating a more immersive experience for such categories of users. Though a number of studies exposing the benefits of the adoption of haptic feedback to ease music perception already exists, they almost always lack of technical details on the characteristics of the tactile stimuli offered to the users, thus hindering reproducibility and wide-scale adoption.
The goal of this thesis project is the quantitative assessment of the vibrations induced on a thin metallic lamina when hit by soundwaves generated by a loudspeaker reproducing audio signals, depending on the characteristics of the audio content being reproduced (e.g., timbre, pitch, tone, rhythm…) and on the loudspeaker technical specifications (e.g., traditional versus directional loudspeakers). The study will be complemented by test campaigns involving human subjects, to assess the discrimination capabilities among various types of vibrational stimuli. The thesis student will be co-tutored by Dr. Louena Shtrepi (DENERG, Politecnico di Torino).
Required skills knowledge of signal processing techniques and of theory of vibrations
