Abstract: Business travel is at an all-time high despite the plethora of video conferencing applications available in the world today. One major drawback in many of these applications is a confusing interface which may require a large amount of setup time and training. The second major drawback is lack of security which can lead to less use of the system due to lack of trust regarding private interactions. In this paper, we propose the "One Space" video conferencing user interface. Through the One Space interface, all persons in every connected room have the same view of and control over the user interface. The view is spatial in orientation, contains no nested menus, and information which is private cannot be accessed by those who lack permission. All icons are pictorial and represent common objects found in and around the room. A One Space interface overcomes many of the drawbacks of current video conferencing applications. Utilizing the One Space guidelines when designing video conferencing interfaces will provide more visible security assurances and support repetitive use, all while enabling even a novice to use the system to its fullest extent.
