Week 12

 Because the absence of the meeting last week, I don't have some significant updates just optimize the algorithm.

Meeting:

updates during the holidays are very good. but have some problems

problems:

1. can it be a website-base application again? 

this is possible, but not sure whether the time is enough for me to 

2. need to be recalculated or restored by a better route?

yes

3.the recording method is not good, by using fixed length step to accumulate the distance 

this can be fixed by changing the recording sensor
