IFD:Printing Acoustic Interfaces

Fachmodul
Printing Acoustic Interfaces
Instructor: Clemens Wegener
Credits: 6 ECTS, 2 SWS
Capacity: max. 12 students
Language: English
Location: Marienstrasse 7B, R002
First Meeting: 9th April 2019, 9:15 AM

Description

This course focuses on printing acoustic sensors for the sensing of structure-born sound. Print processes like silver ink-jet and screen printing can be applied to manufacture acoustic sensors. Tapping and sliding gestures on an acoustic surface have a different sound impact, which can be leveraged to design new interaction concepts. The course focuses on developing a concept for acoustic interaction and developing a working prototype with appropriate sensors and signal processing abilities to materialize your concepts.

Admission requirements

Knowledge in Hard- and Software would be highly appreciated, but is not a requirement.The needed functional components will be explained throughout the course. In parallel you will develope your own interaction concepts or product prototypes. For buying electronic components, a little budget of 10€ to 20€ is neccessary. Of course you can keep your manufactured works.

Evaluation

Successful completion of the course is dependent on regular attendance, active participation, completion of assignments, delivery of a relevant semester prototype and documentation. Please refer to the Evaluation Rubric for more details.

Course Material

Here you find learning material in the form of circuit simulations, that lead you to the understanding of amplifiers and other signal conditioning circuits that we use throughout the course.

• The foundation of understanding electric circuits is Ohm's law.

Ohm's Law

• A very powerful concept is the voltage divider, it allows us to attenuate (but not amplify!) any voltage in any circuit

• We will use the OpAmp (=operational amplifier) to amplify the small signals from our microphones to usable and less noisy signals before we digitize them in the computer
