Shadow Clones: an Unattended Visual Interface to Enhance the Task Performance in Multiple Space using Gaze-Switching

We propose Shadow Clones; a user interface with unattended visual information to accomplish multiple tasks in multiple spaces using fast-gaze-switching. Shadow Clones interface provides not only a cursor on the view area the user is gazing at but also cursors on other view areas that the user is not gazing at. To validate Shadow Clones, we designed a successive reaching task and compared our approach to single-cursor interface, in which the cursor was displayed in the view area that the user currently gaze at. The results showed that the shadow clones’ condition improved performance while maintaining fast switching. Our approach is expected to be an interface design for interactions in which a single user can manipulate multiple bodies.
