This was generated for a project for ISEN 635 at Texas A&M. The goal of the project was to use information theory to evaluate the effectiveness of different vibrotactile notifications on iPhone and Android devices.

Python GUI:

• Takes subject info
• Initializes study with specified parameters
• Communicates with arduino Nano over serial USB to send vibration patterns
• Prompts user to select which type of notifications

Arduino Nano:

• Receives serial input from Python GUI
• Turns on and off vibration motor as commanded by serial data

Features:

• Vibration patterns can be set within vibration_patterns.py
  • Each dictionary contains a set of vibrations
  • Each vibration is formatted as a list of lists.
  • Each list contains two values: [duration_in_ms, intensity].
  • Both should be a single byte ranging from 0 to 255.
• gui.py imports all dictionaries in vibration_patterns.py
  • Vibrations can be manually triggered within "Vibration Demo" menu
  • Vibrations can be plotted using "Plot Vibration Patterns" button within "Vibration Demo" menu
• Set number of trials and directory for results file in Settings Menu

Hardware:

• Arduino Nano
• 5v Vibration Motor Module (https://www.amazon.com/dp/B091TV6RTT?ref=ppx_yo2ov_dt_b_fed_asin_title)

Hardware Connections:

• Arduino Nano USB > Computer USB port
• Arduino Nano 5v > Vibration Motor Module VCC
• Arduino Nano GND > Vibration Motor Module GND
• Arduino Nano I/O Digital Pin 3 > Vibration Motor Module IN
