Corner Collection User Study

This user study is meant to collect single-stroke sketched samples of connected lines and arcs. In this study,

• A line is a line segment
• A polyline is a set of connected line segments
• An arc is a part of a circle
• Every sample drawing should be drawn in one stroke (i.e. without lifting the pen from the screen during drawing), and the program will not let you draw more than one stroke between saving (which will move you on to the next item to draw).
• If you accidentally raise the pen before you are finished, or you draw the wrong thing, you may press the Clear button and start over for that drawing.

Once the applet loads, simply enter in the requested information and perform the study. If strokes do not appear when sketching, press the "Clear" button. After drawing the requested shape, simply press the "Save" button.
You will be asked to draw 4 samples of each of 16 various combinations of lines and arcs.
When done, simply close this window. Please do not close it until you have completed the study. Thank you for your participation!
