4 Inputlog Help INPUTLOG Preprocess Preprocess 13 Filter Recode Segment Convert 15 Filter Recode Recode Select one or multiple files to recode Create new groups Tip: group the new idfx-files in a new folder Trainingschool keystroke logging Antwerp 3

5 Recode Segment Convert The recoded idfx files can be saved at a new location 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 You can merge data with the Tobii eyetracker You use the Time Filtered and Recoded files as new input for analyses Merge eyetracking General analyses + eye tracking 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 Elaborated information in the Inputlog manual Trainingschool keystroke logging Antwerp 4

8 Summary analysis: Product/Process 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 { # } pause time in milliseconds [ BACK ] events other that character production < text > insertion of copied text Process graph Pause analysis 42 Trainingschool keystroke logging Antwerp 7
