WallTokens: Surface Tangibles for Vertical Displays

Abstract

SurfAirs: Surface + Mid-air Input for Large Vertical Displays

“…Large vertical surfaces such as high-resolution wall displays allow users to work with a very large information space. Such displays are particularly suited to, e.g., interacting with geographic data [3,12], performing visual analysis [33,39,60], sorting large collections of data [28,41], or even playing games collaboratively [66]. Large vertical surfaces enable two levels of interaction.…”

“…Taking inspiration from projects with tabletops such as [35,63,68], some systems rely on tangible controllers to interact with vertical displays [12,23,40,66]. Recent empirical results suggest that such tangible controllers are even more efficient and more comfortable than touch gestures for manipulating virtual objects displayed on the wall [12]. When their design makes it possible for users to attach them to the surface [12,23,40], users can free their hands at will.…”

When their design makes it possible for users to attach them to the surface [12,23,40], users can free their hands at will. They can also easily switch between multiple tangibles.…”

“…As Figure 1 illustrates, users can manipulate them on screen (surface input), in the air (mid-air input) and transition from the surface to the air during a single manipulation (hybrid input). Like WallTokens [12] or Geckos [40], a SurfAir can be attached to, and detached from the vertical surface, making it easy for users to free their hands or grab another SurfAir.…”

Engineering Interactive Geospatial Visualizations for Cluster-Driven Ultra-high-resolution Wall Displays

“…Geospatial data visualization has been a key application area of our research on wall displays: interaction techniques for highprecision pointing [4], for multi-scale navigation [5], or more recently tangible interaction [2]. But the amount, complexity and heterogeneity of geospatial data have also led us to research questions related to the engineering of interactive geospatial visualization early on, focusing on toolkits to display elaborate 2D multi-scale information spaces [7] as well as input management systems [1].…”
