ABSTRACT
In this paper, we present an exploration of an interaction technique designed for large and high-resolution display environments in collaborative work situations. We introduce the Pseudo-Direct Touch technique to enable users to interact with a large display from a distance through a transparent touch frame. The touch points on the frame are projected onto the distant large display, so that users have the impression of touching on the large display directly. This approach combines the advantages of intuitive interface for individuals and interaction design that supports unobstructed awareness and face-to-face contact for collaborations in display environments. We assessed our design and performance of our technique in a user study, and gauge the effect of parallax on accuracy during absolute selections. Finally, we trialled a prototypical user application and observed fluent interactions by most participants.
