The psycholinguistic study presented in this article was realized for the European Research Project ‘EYE-to-IT’. Using an original technical development combining three technologies, namely electroencephalography (EEG), eye tracking (EYE) and keystroke logging (KEY), EYE-to-IT aimed to develop technical solutions for studying the cognitive mechanisms of translation and for helping translators to perform better while translating texts. After first exposing the transcoding challenge existing in each situation, the author discusses the advantages of each measurement technique (EEG, EYE and KEY), as well as the advantages and drawbacks in combining them. The author will describe the experimental setting, before presenting the results and discussing some findings.
