In-Depth Information
accordingly. The specified dtravel expense limit forced the speaker to
construct a reasonable travel plan. In order to avoid the previously mentioned
problems associated with providing these details on a text handout, we used
concrete physical objects to represent the travel details. For example, a
calendar with a particular day marked was used to indicate the day of the trip,
and a wallet containing banknotes was used to indicate the travel expense
limit.

The Experimental Setup
We also improved the experimental setup following Phase I. In order to let
the next speaker warm up and to ease nervousness, we had the next speaker
sit beside the current speaker and act as a passenger, as depicted in Figure 3-
6. The next speaker can then monitor the conversation between the speaker
and the operator.
