Day 14: (Mon Oct 18, Week 8) Real-Time Program Structure

Notes for 2021-10-18.

New Assignments

1. New assignment not yet published, but each pair will be building a simple musical instrument. We will play these as an ensemble.

Administrative

• Comments on mid-term grades.

Agenda

1. In-class game demonstrations and critique.

   • Today we’ll begin a slightly more formal critique scheme.

2. My oversight: please add your CircuitPython code to your game post, either as an attached file (if long) or as a SyntaxHighlighter Code block (if brief).

3. Discussion of real-time event processing.

   • Classification: Decision Tree Classifier - Raspberry Pi Pico

   • Real-time event loops: Gesture Game

   • Model-based interpretation: state observers, FSM parsers, probabilistic (HMM, POMDP)

   • Deeper followups: SciPy Signal Processing, scikit-learn.

4. In-class experiment: sound production.

   • Work with your new partner.

   • Find different ways for the marbles to create sounds, either tonal or rhythmic.

   • Sketch several ways the process could be autonomously modulated using actuation and sensing.

   • Identify a suitable means for human interaction.

   • Identify a symbolic representation for external events as a text string.
