Before you proceed

Inputlog versions
The latest version and previous releases of Inputlog are freely downloadable for (academic) research purposes. We strongly recommend you to carefully read the installation instructions before you register and install the software on your computer.

Manual and Documentation
The user manual and some fact sheets that document the use of the different components in Inputlog are made available. These documents also provide more background on the rationale that is used in the analyses, and they explain the algorithms that are used in the different analyses.

Inputlog version 8 October 2020

Characteristics of Inputlog 8

  • Windows 10 Inputlog is optimized for Windows 10.
  • Copy tasks in eleven languages A standardized copy task has been added and is now available in eleven languages. The analysis of this task enables researchers to characterize motoric and low-level processes from different perspectives (e.g., with respect to bigram frequency, task complexity, keyboard layout).
  • Refined logging procedure The logging procedure has been refined and recognizes the active document in a more precise way, even in complex source interactions.
  • Advanced preprocess possibilities The preprocess possibilities include new and advanced—automatic and manual—filtering and recoding options to optimally prepare your data analysis.
  • Optimized analyses Several analyses have been refined and/or optimized. For instance, the pause analysis now includes geometric means and coefficients of variation, P-bursts and ratios are reported in more detail. The source analysis now also addresses source interactions at the interval level. The process graph can dynamically be adapted to your needs. A word pause analysis is also available now.
  • Merging facilities in postprocessing Postprocessing offers now merging facilities to conveniently and accurately merge analyses of large scale data collections, including the copy task.
  • Versioning: An option is added in the File menu that allows saving a timed, intermediate version of the main document during the writing process.
  • Debugging Most bugs reported by users from all over the world, have been taken care of. Thanks for your feedback.
