Distance activity debugging and calibration

Project Aim - To test the accuracy of the "Acoustic Tape Measure" activity on the XO laptop and attempt to find ways to resolve accuracy issues based on our results.

Project Collaborators (Members of the IMSA Chapter)

Experimental Design -

  • Experiment 1 - Use "Acoustic Tape Measure" to measure pre-set distances and check the accuracy. Repeat this 3 times at each pre-set distance and over multiple different pre-set distances (1m, 2m, 4m, 8m, 16m, 32m).

Results -

  • Found a linear relationship between the actual distance between the computers and the program's calculated distance.
    • y = .9941x - .0178
    • r2 = .9999

Graph of Results


Distance of 16m did not display results that were at all accurate. After a certain point somewhere above 10m the program is no longer accurate.
