Distance (formally known as Acoustic Tape Measure) determines the physical distance between two computers by measuring how long it takes sound pulses to travel between them.

===Using the Distance activity===
 
 
 
You need two laptops in order to use this activity.
 
 
 
Steps:
 
 
 
# Launch the Distance activity on one of the computers by clicking on the icon in the Home view.
 
# Share the activity from the Share icon on the activity toolbar (or send an invitation to the another computer).
 
# Launch the Distance activity on the second computer by clicking on the icon in the Neighborhood view (or on invitation icon).
 
# Click on the "Begin Measuring Distance" button found near the top of the activity view on both computers.
 
# The first computer will send an audio pulse; the second computer will respond with an audio pulse of its own; then both computers will calculate and display the distance between them (by default, the measurement is displayed in meters).
 
# This process will repeat until you click on the "Stop Measuring Distance" button or you exit the activity.
 
 
 
Notes:
 
* Try not to move the laptops while they are taking measurements as it will result in a bad measurement. You can move them between measurements.
 
* If the "Begin Measuring Distance" button does not activate, try relaunching the Distance activity again on the second laptop from the Neighborhood view.
 
* Atmospheric conditions can impact the accuracy of the measurement; there are overrides to the default settings on the Atmosphere toolbar.

* The units of measure can be changes by choosing a unit from the combo box on the Customize toolbar. If you chose "custom units", the current distance between laptops will be used as a metric. For example, you could measure the height of a student, Pedro, and then select that distance to define a new unit of measure, the "Pedro".
