Usability Guidelines for Co-Located Multi-User Interaction on Wall Displays

Multi-person Spatial Interaction in a Large Immersive Display Using Smartphones as Touchpads

“…We experimentally explored the viability of various input methods for multiple users to interact with the large screen. These included the Leap Motion device for sensing mid-air gestures (which users found fatiguing and cumbersome to use), a fully voice-driven system (which had difficulty with some users' accents, and was discouraged by some recent studies [27,26,29]), and a smartwatch interface (which proved too small to easily control the large screen). Ultimately, as described below, we use each user's own smartphone as a touchpad to control the large screen, which is both familiar and intuitive to use and has an immediate personal connection.…”

Automatic, Gestural, Voice, Positional, or Cross-Device Interaction? Comparing Interaction Methods to Indicate Topics of Interest to Public Displays

“…Multi-user interaction with public displays may promote social interaction between people, which is considered beneficial in certain cases (Steinberger et al, 2014). Prior research (Nutsi, 2015;Nutsi and Koch, 2015) has established usability guidelines for multi-user shared-screen applications. Elhart et al (2015) propose overlaying applications in viewer's on-screen silhouettes (i.e., their shadows).…”
