Blickshift Analytics: Advanced eye tracking analysis

Blickshift Analytics 1.3.2 (August 2022)

  • Scan Path visualization now takes time unit into account when computing circle sizes, thus requiring less manual correction via setting a reference radius.
  • We implemented a new node that clusters according to Scan Path similarity and automatically groups participants according to that similarity.
  • Labeling Node can now handle re-connecting new nodes. Labelled data stays in existence and is re-used if data set, scenario and subject are the same.
  • Simple Statistics Node now has an option to ignore NaN values.
  • Value Search now has additional options regarding NaN values.
  • Completely new importer with support for many auto-detected formats and better support for automatically importing media files.
  • Scenarios and participants now have user-editable metadata that can be used to group scenarios or participants according to the metadata content.
  • Files can now be opened or imported via drag & drop.
  • Markings that are directly adjacent to each other on the base data are now correctly merged into a single marking instead of staying a split marking.
  • Fixed a bug in the project manager, where stimulus IDs would behave erratically.
  • Fixed a problem that could happen when automatically importing Pupil Labs data located in a folder in a hard drive’s root directory.
  • Bug fixes and improvement of performance.

Blickshift Analytics 1.2.14 (August 2021)

  • Enabled aggregation of stimulus-based visualizations (heat maps, scan paths), if the stimulus name is read from a column, and the data has been grouped according to that column with a group node.
  • Added information about the column type into the columns’ tooltip in the drill down visualization.
  • Fixed a bug in the merge and resample node that could occur, if the data on Input 1 had many rows with the same timestamp and “Clamp to Common Time” was activated.
  • Fixed a problem with importing world.mp4 files from Pupil Labs recordings.
  • Several smaller improvements and bugfixes

Blickshift Analytics 1.2.3 (November 2020)

  • Added support for annotations in the Pupil Labs data
  • Fixed a problem that could occur if Pupil Labs fixation data files are empty

  • Several smaller improvements and bugfixes
