Embedded Acoustic Interfaces

Fachmodul
Instructor: Clemens Wegener
Credits: 6 ECTS, 2 SWS
Capacity: max. 10 students
Language: English
Location: BigBlueButton Online Streaming
Meeting Time: Mondays 9:15 am

Description

We are constantly surrounded by electronic interfaces: elevators, automatic doors, ticket machines, remote controls, voice recognition systems, etc. With a high degree of networking between our devices, interfaces must seamlessly integrate into ecosystems of information acquisition and processing. Thus, ergonomic sensor placement, which integrates discreetly into our accustomed environment, is gaining ground.

The course explores the possibilities of this ergonomic, embedded interaction using the example of acoustic interfaces. We will develop electronic sensor systems for the detection of vibrations (structure-borne sound) in integrated surfaces and experiment with machine learning methods to differentiate between vibration gestures (e.g. knocking noises, friction noises, etc.).

The Course will be taught in video sessions and regular assignments every week.

Course Introduction Video

Admission requirements

Things you need

  • computer or laptop
  • Teensy 4.0 + audio shield
  • a pair of headphones or speakers
  • a soldering iron would be a plus


We will use either the Teensy 4.0 hardware platform or the Raspberry Pi to classify sounds in the environment. Therefore, a budget of (30-40€) should be planned for the Teensy and other components.

Educational Requirements

Introductory level of programming is a requirement!

Evaluation

Successful completion of 50% of the assignments. Realization and documentation of a completed semester prototype and a final video presentation. Please refer to the Evaluation Rubric for more details.
