| Start up/shut down time |
We don't want the user to wait too long. |
Stopwatch. |
| Hall effect sensitivity due to distance |
So that the user can change colors on the pen easily. Have a variety of magnet strengths. |
Hooking it up to a multimeter. |
| Response time of IR to table |
System doesn't lag - user experience. |
We can videotape users using product so we can measure delay. |
| Max resolution of AirPlay streaming |
User experience. |
Test with different resolutions from different devices. |
| Accuracy & Precision of IR tracking |
Accurate respresentation of user input. |
Putting multiple dots and measuring distances between pen & dots. |
| Temperature of projector under table |
So system doesn't overheat and surpass operating temperature. |
Overload system to see how much stress it can take to reach undesired temperatures. |
| Optimal wavelength & power of infrared |
So we can use the optimal infrared to better increase accuracy and precision |
Repeat A&P test with different infrareds. |
| Distance between infrared pen and table |
So there is no unwanted behavior. |
Measure distance between pen and table when pen is first sensed by the table. Will test at different locations on table. |
