Recode
Segment
 The recoded idfx‐files can be saved at a new location
You use the Time Filtered and Recoded files as new input for analyses
Convert
 Select the original idfx‐file that you would like to segment
 Choose whether you would like to include the initial pause  Choose your key delimiter

Merge eyetracking
 You can merge data with the Tobii eyetracker
General analyses + eye tracking
22
General analyses - condensed
 Data needs to be structured in a specific way
 An offset between Inputlog and Tobii is calculated
 Two type of merges can be performed
 General analyses including detailed event based eye tracking information
 General analyses including aggregated eye tracking information

Summary analysis
Linear analysis
 Be aware that these automatic calculations might not be what you want to work with. E.g.  Active writing time is not the sum of all action times
 Average pause time varies if you select a filter (e.g. All input modes 24s, only key strokes 40s)
General advice
Check summary analysis with the purpose of your research question. Perform small test sessions to understand the output of the data. Linear analysis
