Gantt Chart
4
Previous Weeks Goals

• Divide labor tasks
• Design the graphical user interface (GUI) -
  Michael Ferguson
• Interfacing the audio API - Fazly Fauzy and Greg
  Reneff
• Data processing - John Kooker
• Solidify vision for program in one week

5
GUI Development

• Two GUIs are to be coded
• Physicians console
• Self-administering console
• Created GUIs must be coded to call the already
  created tone functions

Physician GUI
7
Tone Generator

• Tone Generator function is written
• Creates wavetable based on arguments (frequency,
  amplitude, time)
• Success sound output on Linux using redirection
• Next step moving to Windows

8
Calibration

• Speakers typically have uneven frequency
  responses
• To compensate, we developed a simple calibration
  algorithm
• Sweep frequencies, record actual response
• Calculate gain difference, write a routine to
  automatically compensate

9
Plans For This Week

• Port code to Windows
• Start coding GUI callback functions
• Refine testing algorithm
• Begin program construction

10
Summary

• We have a preliminary GUI, the tone generator
  function, calibration technique, and testing
  algorithm
• Next week, we will have a prototype GUI which
  interfaces with the tone generator
