In the past 20 years, new technologies such as key-logging and eye-tracking technologies have enabled translation process research to go deeper and further. Digital technologies can also be applied in interpreting process research. This paper focuses on how smart pen technology can open up new dimensions in interpreting research, specifically how Neo smartpen N2 can be used in digitizing consecutive interpreters’ notes. A case study is introduced using Neo smartpen N2 to record the note-taking process of a professional interpreter and employing ELAN to annotate notes, which are classified into 6 types. It is demonstrated that the smart pen, together with annotation tools like ELAN, makes it possible for researchers to capture the note-taking process and make precise measurements, which offers precious hard data for identifying details in the note-taking process and analyzing note-taking as a resource-management and decision-making process in consecutive interpreting.
