2. Status Update Concept: A device that acts as a virtual instrument Update: –Data logging, 6 accelerometer channels from one T- Mote (Emily) being read and sent to receiver (Momma Priya) –Fully functional system working with input from both accelerometers. Data from one accelerometer controls when a sound plays and the other controls the pitch of the sound. –Successfully tested portability (range) of Emily in outdoor setting –Constructed new Air Combo sender (Simon) –Putting finishing touches on a gesture recognition system using k-Nearest Neighbor algorithm.

3. Testing Plans –Bootstrapping When PC receives message from new sender, and adds it will indicate this. –Tear Down PC realizes it hasn't received a message in a while, alerts the user to this. –User Gestures PC recognizes that the sender has gestured; plays associated sound –User Does Not Gesture PC sees data from the sender not correlated to a gesture; no sound is played –Multiple Users PC handles above use cases for more than one sender –Reliability – Data Loss PC misses a message from sender; does not play a sound as if user gestured, missed messages are logged and reported on the PC. A+

4. Test Data Observed percentage of messages received with sender (Emily) varying distances from receiver (Momma Priya). Standard: 28 byte packets Results: Somewhat as expected, reception decreased as distance increased. But large sources of error did exist.

5. Looking Forward Perform an indoor test for portability. Finalize code for testing other Finish gesture recognition training. Test multiple Air Combo’s simultaneously
