I wanted to build a device that uses the piezo microphone and a raspberry to create relaxing mood with sounds and tactile media. The result is a first feasible approach. In my opinion listening to the device is surprisingly immersive. But that's a purely subjective assessment. For further improvement, it would be necessary to develop a user study that verifies the benefits. Also the following points should be discussed: | I wanted to build a device that uses the piezo microphone and a raspberry to create relaxing mood with sounds and tactile media.

# The device is too big and difficult to transport. The sound processing should be optimized to a system on a chip, such that the whole processing could fit in a regular fidget cube. | # The device is too big and difficult to transport. The sound processing should be optimized to a system on a chip, such that the whole processing could fit in a regular fidget cube. Because it is addressing adults the design could be more clean and subtile. | ||
# The audio processing doesn't show the potential yet. There are still too many pseudo-random controlled values. Instead of randomness I would like to use more input signals from the user. I think it would be cool to add harmonics dependend on the orientation of the device, which can be measured by a gyroscope. | # The audio processing doesn't show the potential yet.

It was the first time I soldered a circuit board and cost me more time than I thought. Also programming with components on a graphic interface was a new experience for me. I think as a computer science student it is still more comfortable for me to write my code as text. I tried to write clean and commented code as good as possible, but general coding convention did not fit in the approach of Pure Data. | |||
