2. Test Cases Concept: A device that acts as a virtual instrument Update:
Data logging, 6 accelerometer channels from one T-Mote being stored
Working on gesture recognition (using AI principles) and risk mitigation
Test Cases:
Bootstrapping
PC sees message from new sender, and adds it to the sender list
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

3. Performance Tests Latency Portability
Important for validity of gesture recognition
Latency to get data through the system determines how fast we can detect the user’s gesture
Measured by average by sending a large number of messages from the T-Mote to the data logger on the computer
The total time of these messages can be measured and so the average latency can be calculated
Portability
Important because it sets the stage (almost literally) for a variety of usage scenarios
Measure distance from the sender to the base station, while recording the number of messages sent and the number of messages received
Look for point where we have 99% received messages/total messages
Varies with the multiple sender use case - interference.

4. Testing Process Performance tests Functional tests
Write test scripts to speed up process
Functional tests
Harder, because they need to include a user
Instruct user to perform predetermined gestures
Count number of gestures the user made vs. the number of sounds that played

5. Looking Ahead Difficulties Lessons Learned: Next Steps User testing
Gesture use case most difficult to test
Lessons Learned:
Gesture recognition is hard
Make sure you're reading all of your channels instead of just one six times
Next Steps
Finalize Gesture Recognition
Multiple T-Motes
