 What we built here is a favorite in this analyzer, so where this idea came from is at many of us play table tennis and so we had this smartwatch which had an accelerometer in it. It immediately occurred to me that I could try it out to measure what kind of strokes I played in my table tennis game. Because I had fun about building this on a smart phone but the idea of using a smart phone, tying it around my arm was a little too crazy. So we gave this a shot and we will let's see how much we can do it. So let's see a demo. So what we've done, so we basically used the smartwatch to calculate the acceleration and based on that we've calculated the short side of table tennis player takes. Basically we've been able to classify it into two data gates for now. One is the front hand that we play and another is the one in the back hand that we play. So you just see a sign to start a stock recording. What's the start to relay messages to the phone? The accelerometer messages to the phone to the broadcast receiver and the phone will to the background processing or storing these messages. And we use certain lot things in the back end like for example we keep 5 messages in a row and we try to analyze the x, y and z coordinates of each 5 messages and we try to then calculate how the hand of the person is moving and at what state it is moving. So we've been decently successful in trying this out. Okay, I think there is some great part. I'd say either what exactly we were able to do. So we were able to classify it into two more categories. We were able to map up forward and how we could do that. We saw that the z coordinates remain fairly constant for this short and for x and y coordinates moved in a specific way and when you did this backwards in the same way the z coordinates were inverted. The z coordinates moved in a similar way. These were the two that we did successfully. We also tried to do the job and successfully do the mission. So that was the theory. I'll just say by the time you come to us later. So we were planning to store these all the, store the player page in a database and then calculate the player page often and what parts you need to include in the work you do. Thank you guys. Any questions?
