Results Review of Microphone Prototype and LabView Detecting of Human Errors Algorithm
Author: Minh Anh NguyenColorado State University

Outline of the review• Update on tasks from the previous
meeting• Microphone prototype• LabView Results for detecting
methods/algorithms for audio files
Update on labView
• Need: Vision and Motion package to analyze the images
• Issue: – The Vision and Motion programming/function
package is missing or not available for the Labview 2014 and NI myRio software
• This issue is resolved
Image test• Simulation mode– Make sure image files are loaded into the workspace
without any issues.– Make sure a correct file is loaded– Plot histogram of the image– Verify that the histogram value is correct.– Positive test: load two image files which have 2
different images and verify that the test results show the difference.
– Negative test: load two image files which have 2 similar images and verify that the test results show the same thing or match.
Labview results for comparing two images which are identical
LabView results for comparing two images which are not identical
LabView results for comparing two images which are not identical
Audio test• Simulation mode– Make sure audio files are loaded into the workspace
without any issues.– Plot and listen to audio files; make sure a correct file is
loaded.– Verify that the FFT value is correct.– Positive test: load two audio files which have 2
different signals and verify that the test results show the difference.
– Negative test: load two audio files which have 2 similar signals and verify that the test result show the same thing or match.
