Off-Surface Tangibles

WallTokens: Surface Tangibles for Vertical Displays

“…Future work includes the design of such interaction techniques that actually combine tangibles with other modalities. We also plan to refine the design of WallTokens to track their position and orientation when users hold them in the air, as recently proposed with the concept of Off-Surface Tangibles [7], in order to make it possible for users to rely on WallTokens for distant interactions with the wall.…”

“…6 The stimulus' fill texture turns into a checkered one after a 2.5 to 3.5 s random delay, instructing the participant to detach the token from the wall as fast as possible. 7 A final stimulus appears 30 cm to the left. It is filled with a checkered pattern as soon as it appears, indicating to participants that they should place the token in this location and attach it as fast as possible.…”

“…Overall, seven token recognition errors occur among 324 measures. Two occurred at step 1 (both for participant A2), five at step 7 , and none at step 2 . There was no systematic pattern regarding the confusion errors.…”

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

“…However, all existing tangibles for vertical displays are tracked only when in contact with the display. On the opposite, the SurfAir controllers that we propose are actual hybrid physical controllers that implement the concept of Off-Surface Tangibles, which has been sketched only by Cherek et al in the context of tabletops [10]. SurfAirs are tracked both on the surface and in the air, and enable interactions that span across the two.…”
