TrailBuddies

Hiking buddy suggestion influenced by the users' common trail habits.

This app logs the different hiking activities of the user, and then compares them to the activities of different users. The users' activities are clustered depending on the level of difficulty of their regular hiking. The difficulty is calculated based on three factors : trail circuit length, trail circuit duration, trail circuit max altitude. When a user is looking for a hiking buddy, the app tries to suggest one or many that have a certain compatibility depending on their habits.

After collecting sensors raw data which are a set of latitude and longitude couple called Geopoints, it is time to calculate the length of the trail circuit. To do so, the application's algorithm takes each couple of Geopoints as input, with the measure unit of latitude and longitude, and returns the distance between these two points. As for the measure of trail's duration, the algorithm stores two times: the trail's starting and anytime which are system's timestamp at the beginning of the trail and the end of the trail. These steps are done in a background-task.

Measuring the length of the trail circuit and its total duration.

Clustering every “trail” into one of three different classes: Easy, Medium and Hard.

When a user searches for a hiking buddy, the app will look for another person with similar activities (has a number of trails within the same cluster).

1. Microsoft Visual Studio 2015 Community
2. Windows Phone 8.1 SDK
3. Parse .Net + Xamarin SDK >v1.6.1 (Requires sign-up)
4. Newtonsoft.Json JSON framework for .NET

You can build and test the solution from within Visual Studio. The project has been tested on both emulator and real device.

An account has been created for the purpose of the demo:

• Username: Demo
• Password: 1234

We are using Parse to store the collected data and the users, so you will need to have internet access for this to work.

If you're going to use the emulator, make sure to provide the app with a number of locations so it could measure the traveled distance.

For this demo an “application Key” and a “.NET Key” have been provided in the code. These keys are required when using the Parse SDK in order to store and retrieve data.

If you're going to fork this project, you should locate 'ParseClient.Initialize' in the code and change the previously mentioned keys.

Documentation about the Parse SDK and a getting started guide are available here.
