Results of the design:

Speed of Execution

The device itself has a timeout of 300 ms between allowed between every single button click. The speed at which the predicted data is sent over is dependent entirely on the action of the user. Taking into consideration aspects such as when they are pressing the button and when they actually begin to make a deliberate movement. Once the capture process begins however, it takes roughly half a second to make a prediction and then another half a second to send it over Bluetooth.

Accuracy

Due to our algorithm and it’s “safety first” approach, the accuracy of the directions is about 80-90%. This number is rather impressive; however, is a little less impressive when you put it in perspective that it only sends out a direction on average once for every 1-3 movements. Yes this is a large range; however, the accelerometer does vary in performance for some reason and generally is able to get the horizontal/twist motions very well roughly once for every 1-2 and once for every 2-3 vertical motions.

Safety

Safety is not really a huge concern with our design as everything is insulated and the power is regulated down. We ensured there were no cold solder joints which could pop off and cause shorts or anything of the sorts. The device is relatively small so should you drop it on your toe or something like that you should be fine, should. As far as Bluetooth goes, we are using a chip that has Bluetooth regulations already considered.

Interference

As far as interference with other groups goes, we have yet to have an issue with this!

Usability

Everyone can use it!
