Sound in interaction

A.Y. 2021/2022
Overall hours
Learning objectives
The course aims at providing students with knowledge regarding principles and technologies for the design, the synthesis, and the rendering of sound in interactive contexts. The main application domains include multimodal virtual and augmented realities, sonic interaction design, assistive interfaces, digital musical instruments.
Expected learning outcomes
At the end of the course, the student shall be able to design models for the synthesis and rendering of sound, and to implement them on real-time plaftorms. Additionally, the student shall be able to effectively communicate the learning outcomes, using the modalities of scientific writing.

During the lectures, the instructor provides references to several scientific papers.
Additional complementary material prepared by the instructor is made available through the web site of the course.
Assessment methods and Criteria
The exam consists of the development of a project, which has to be documented through a written essay in the form of a scientific paper, and has to be critically discussed in an oral test. The project can be developed individually or in a group of two students.
The evaluation is given in 30ths and is based on the following aspects: mastering of the course topics, ability to apply the acquired knowledge to solving actual problems, logical and critical thinking.
