Week 13

 The application suddenly have some bugs, and I fixed it.

Problem:

1. fixed length step (72 cm)

used to using sensor to calculate how many step admin has walked

solution:

I see the "measure" application in iOS system is good, and which can get the distance with a high precision, so base on this, I think I can using the similar method or APIs to enhance the precision of my project.

By some research which is using AR kit, so which is similar with the navigation.

So this week I've done a lot of tryings and testing to make sure this new method is available.

Meeting:

demo is good as well.

Problem:

1. precision is not good.

reason: because QR code is not fixed at the place at present, as also the direction of user or the initial state is not fixed which causing the error occur. So, I may say this is acceptable for present.

2. Arrow can be more simple to give a clear instructions (also trying to reduce the bad feeling by the not good precision)

solution:

1. simplification the arrow ( no need a dynamic line to show where to go, an arrow to the crossing is good)

2. segment the line, and scanning multiple times when achieve a different node which can also reduce the error.
