SPBView: An extendable data analysis and combined visualization tool for saccadic eye-movement, pupil size, and blink detection

During the last 20 years, eye-tracking has become an important method for researchers in different fields like medicine, psychology, marketing, and even gaming. However, analysis tools are scarce. In this paper, we introduce our openly available software solution that can visualize saccadic eye-movement and calculate reaction times from saccadic paradigms, e.g. the antisaccade task. It further includes an error classification and processes the raw data into a trial-by-trial (target) output. Reaction times and error rates are typically estimated as performance indicators for this task. Moreover, the tool includes blink detection as well as a pupil size based fine tuning, which may be interesting for research assessing cognitive load and synchronization processes. The software is multi-platform, succinct, and easily extendable.
