+A set of components which simplify human behaviour experiments developed in the Unity engine. UXF 2.0 supports Desktop, PCVR, Standalone VR, as well as Web based experiments for full remote data collection, with different data output modes. This is the development project, if you want to download the package, do not clone this repository, see "Get Started" below.

 ### Data collection
 
-UXF automates the process of collecting data.
+UXF automates the process of collecting data. How the data are stored depends on the platform (PC, Web, etc) as well as your configuration of different "Data Handlers". For PC platforms, you probably just want to store data in files on the PC locally. In that case, the File Saver data handler will output data in several forms: 
 
-**Behavioural data** is collected with 1 row per `Trial`, and automatically records some values such as the timestamp of the start and end of the trial. Developers can easily record observations of any type and associate them with a trial. Data is output with one row per trial in a results csv file.

Developers can easily record observations of any type and associate them with a trial. Data is output with one row per trial in a results csv file.
 
-**Continuous data** is data that is measured continuously over time during a trial. The main use case of this is to track the position and rotation of any object in the scene, which is captured at whatever frame rate the application is running at (in the `Update()` loop) by adding a `PositionRotationTracker` component to a GameObject. This can be used to track positions of user controlled objects (such as hands or head in a virtual reality application) or an arbitrary object in the scene (e.g. some kind of stimuli). However this system is generic and developers can create their own `Tracker` classes that perform measurements of any variable during trials.

-A `UnityEvent` is invoked on `Trial` begin and end, allowing you to easily trigger presentation of stimuli at trial start (for example).
+For Web platforms, the data cannot be stored on the participant's PC. Instead, data can be uploaded to a database. UXF handles all of the hard work for you and automatically uploads the data files as long as you set up a DynamoDB database using Amazon Web Services. 
 
-### CSV Participant List

-A participant list feature is used allowing experimenters to optionally pre-prepare participant information. Additionally, this participant list is shared between experiments, allowing easy cross comparison of observations within participants.

 A UI is available (but optional) allowing loading of participant data from file (or add new participant data). Variables that are collected are customisable and can be used in the experiment (e.g. a parameter for a participant's age could be used to change the difficulty of the experiment).

 ## Example
 
 UXF is built around the idea of separating the specification of your experiment (the "what") and the implementation of your experiment (the "how").
