Abstract

Nowadays, people often have to input information on public terminals. By doing so, they might disclose information to strangers looking over their shoulders. In this paper we introduce a new way of interacting with public terminals, which offers more privacy by using a personal mobile device to enter private data. It allows the users to choose which information is to be regarded personal, which can then be entered on their mobile device and is hidden from the screen accordingly. Furthermore we created a prototype and conducted a user study measuring users' input performance and to collect opinions about the system's usability and practical value. The paper concludes with some ideas to make the system even more useful.
