Tracking User Clicks Using the xAPI Part 2

05 Aug

We have a working LRS! It has been a couple of months since the first post on this that you can see here. Due to other projects progress has been a little slow. Back in May we got a couple solid weeks of time to work on the next step of being able to see what users are doing in the software and comparing that against what an expert would have done. When we left off we were making statements, but writing them to a text file. We now have a working LRS powered by a SQL database that can store the statements as they are produced by the system. So lets walk through a few topics here to get you up to speed on what we have done.

The Statements

Below is an image of what the statements looked like when we were first producing them.


You can see we are missing a couple of things, namely for us the URI and the time stamp. So the first thing we did was create the simple web page here that has our URIs for one of the verbs we are using: created.


Interacted, the other verb, was available through the ADL so we set the URL to the ADL repository.
Now that we have that set, here is what the statements looked like:


You can see we are displaying the URL for the verb URI. Finally we needed to add the timestamp. This will help us gauge how much time it takes the user to perform a task. So in the TCL file we were able to pull the time from the computer and display it in the statement. That got us to what we think are good statements for our system. Next we needed to store them.


I am very fortunate to have a very good database guy that works with me. He went through the xAPI spec and made tables in the database for each item that can be written in a statement. So if we ever want to expand to store more items from the statements we already have the infrastructure built. As I stated in the first post, we are starting small and will work our way up to more complex statements as necessary. Now that we are storing the statements we needed to display them. We built an HTML page that will display the statements in real-time. Now as we are writing to the database, we are displaying them in the web page as you can see in the image.


We are super excited to be at this stage where we are seeing the statements being generated real-time.

The Next Step

We are now at the point that we have distributed the TCL file to many people to start using in their day-to-day activities in the software. We feel that this will help us find the patterns that we need to build higher level activity statements. What I mean by that is that although all the clicks are great, as we compare them to one another, we get a good idea of what the user is doing. On a higher level, we can tie these click patterns into context-style activities which really starts to give us a feel for what the user is trying to do. Our first goal is certification testing using the xAPI. Comparing clicks to clicks to see if the user did the right thing. We are going to accomplish this be creating a Gant chart of the clicks which will allow for an easy visual comparison. Our ultimate goal to be realized in the next 4-6 weeks is to provide reccomendations to the user as they use the software. We think using the activity statements is the way to do that. Build the clicks into a pattern and use those patterns to recommend pertinent help when people need it. We would love to hear your thoughts on the path we are taking and where we are going. Stay tuned as the next month is going to be exciting!
