1. Product Overview

Global Counselor is a kiosk and tablet application that lets people who speak different languages talk to each other in real time. It is used wherever staff need to serve foreign visitors — schools, hospitals, police stations, tourist information desks — so that the counsellor and the visitor can each use their own language.

참고

The app itself displays the name 글로벌 상담사 (Global Counselor). This manual uses "Global Counselor" throughout.
