This week I mainly worked with Xiao to do the testing. My main focus is on latency. Previously the testing method is inserting time.time() before sending and after receiving the request and find the time difference divided by 2. However, this method seems to have some flaws since it isn’t necessary that send and receive times are equal.\u00a0 Therefore, we again used the slow motion camera to measure the time the button is pressed and the time input changes on the screen.\u00a0 The result hovers around\u00a0116-125ms which is around 6 times worse than our design requirement of 20ms. A few improvements we later discussed can be reducing the response message length to minimum and removing all the prints on the screen. We also make sure that the latency should be tested at different distances.
\nNext week, we will refine our testing and start working on the poster and final report. I will also try to invite 3 users to test our product.<\/p>\n","protected":false},"excerpt":{"rendered":"
