Developers are asked to create a mobile application that can train users to improve their technique in capturing videos using the Scent Explore app. The new app should provide a test suite where users can practice their video technique and check if they are following the guidelines provided to them for using Scent Explore. The app should correct them when they are not following the guidelines, and provide feedback and tips on how to improve their technique.

The training material in the app can be based on augmented reality and graphics, or else use videos collected by volunteers using the Scent Explore app in previous Scent campaigns.

The guidelines that should be evaluated by the app are:

– Videos should not be taken from up-close, the floating object should be a small percentage of the total frame;

– The camera frame should include some stationary features located at the riverbank;

– The camera should be steady;

– The camera should be perpendicular to the riverbank;

– The device should not be titled – phones should be held perpendicular to the ground and not angled backward or forward;

– The user should keep the camera stable, fixed in position and not follow the floating object;

– The video may include frames without the floating object, by only at the beginning and end.

You can download the full instructions given to Scent Explore users here. Some example of videos (successful and unsuccessful) are located here.

The apps will be evaluated and scored according to the following criteria:

1. The app should be compliant with the video capture guidelines, available here. Each of the seven guidelines will be tested, following the instructions inside the app. Each guideline will be evaluated as either succeeded (Score 1) or failed (Score 0). The sum of these seven scores will be input into the following formula (4*score_sum)/7.

    -Score 0-4: Computed based on the formula, according to the identified invalid user actions

2. The messages should be informative and support the user to provide high quality data:

   – Score 0 (failed): No messages provided
   – Score 1 (good): Messages describing only the user invalid actions
   – Score 2 (excellent): Messages describing the user invalid actions and suggestions for improvement

3. The app should include graphic-design and augmented reality elements:

   – Score O (failed): No or limited graphic elements
   – Score 1 (good): Detailed graphic elements
   – Score 2 (excellent): Detailed graphic elements enriched with augmented reality elements

4. The app should be available for at least Android 6. IOS compatibility and will be considered an asset:

   – Score O (failed): Compatible only with Android version 6
   – Score 1 (good): Compatible with Android version 7+
   – Score 2 (excellent): Compatible with both Android version 7+ and IOS

5. The app should provide a way for Scent Toolbox users to collect data (user experience):

   – Score 0 (failed): The app shows significant bugs which do not allow normal use
   – Score 1 (good): The app provides sufficient interfaces to guide the user towards appropriate data collection
   – Score 2 (excellent): The app supports the user based on his level/needs and provides additional tips and helpful information
