|
| 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".
