The Spree device is reliable when calculating heart rate but not temperature according to the t-tests. The oral thermometer yielded a p-value under 0.05, which shows a significance difference in the data and the pulse ox yielded a p-value greater than 0.05, meaning that the data is similar and reliable. This can also be concluded with the r-value. The r-value for the pulse ox is approaching one which shows a high correlation and the r-value for the oral thermometer is very low which shows a low correlation.

Descriptive Stats and Graph





Inferential Stats

A paired t-test was used for both the oral thermometer and pulse ox, due to the comparison of two samples.

Heart Rate

Standard Deviation Pulse Ox Gold Standard : 21.70

Standard Deviation Pulse Ox Spree: 24.27

R-value: 0.78

T-test (p-value): 0.671

Temperature

Standard Deviation Oral Thermometer Gold Standard: 1.92

Standard Deviation Oral Thermometer Spree: 0.87

R-value: 0.193

T-test (p-value): 1.067*10^-21

The Spree device is reliable when calculating heart rate but not temperature according to the t-tests. The oral thermometer yielded a p-value under 0.05, which shows a significance difference in the data and the pulse ox yielded a p-value greater than 0.05, meaning that the data is similar and reliable. This can also be concluded with the r-value. The r-value for the pulse ox is approaching one which shows a high correlation and the r-value for the oral thermometer is very low which shows a low correlation.



Design Flaws and Recommendations



Experimental Design of Own Device

For an experiment: Locate people already in need of a mobility enhancing exoskeleton. Give those people our exoskeleton and measure the amount of battery used by certain tasks and overall battery life per day. Then, we would measure both the battery used per task and per day and compare this to our competitor exosuits in order to determine if our exosuit is more efficient. As for actual customer satisfaction, we would compare both our own exoskeleton and our competitors’ exoskeleton with common tests, such as sitting, standing, and walking speed. The results of these will then tell us whether our device is more efficient without sacrificing viability.
