The table above is a summary of collect data. Each of the four activity had an Average Time (in minutes), Average Quality of the Paper Airplane, the Average Difference in Back Angle (in degrees), and the NASA-TLX Survey categories. This was used to generate the visuals below.

Due to limited time and resources, GeoGebra was used for angle measurement

The Angle Difference was calculated by taking two screenshots of the recorded motion capture data. The screenshots were then put into GeoGebra where we were able to calculate the angles. The point of reference for each participant was the center of the back and the angle was measured from the hips to the top of the shoulders. The above picture shows how that data was analysed using GeoGebra.

The absolute difference of each angle was taken and recorded into the data table.

These histograms were generated using the columns "Average Time (min)" and "Average Quality". The blue histogram's vertical axis is in minutes for the Average Time and the red is in ratings from one to ten for the Average Quality.

Notice that sitting Straight and Standing have the quickest time, and sitting Straight has the best quality.

This histrogram is used to show how much peope were adjusting their posture on average between each activity. The angles were created by taking two instances from the recorded motion capture video and finding their absolute difference.

Notice that sitting Straight has the smallest difference in posture angle.

Notice...

• Mental demand is relatively consistent throughout

• Physical demand is highest when subjects were standing

• Temporal demand is highest in Control (no posture)

• Performance is rated highest by the subjects when Slouched

• Effort is highest when Standing

• Frustration is highest when Standing
