Appendices
Appendix A.1 Instructions to subjects
"This experiment tests two different input methods for a Palm
Pilot - onscreen keyboard and graffiti. You will enter an address
into multiple fields. It is very important that once you start entering
the data, you complete each task without interruption. You can either
correct your errors as you go along or at the end. The program will
not terminate unless the input matches the correct input. Thus,
accuracy is very important.
In the first part, you will enter the information into the memo
field and then into the multiple address fields. Please inform the
experimenter when you are done with each task so that the time can
be recorded. In the second part of the experiment, you will repeat
the two tasks using an alternate input method"
