Title:


    SplashDisplay: Volumetric Projection using Projectile Beads

Presenter(s):


Entry Number: 19


Description:


    The prime feature of the SplashDisplay is that it uses projectile beads as a display medium that are launched from the table; this means that the tangible medium can be removed from the surface and allowed free movement in air. In current research [1] [2], displays have tended toward fixed mediums and therefore defining and visualizing explosive activity on such displays has been difficult. However, the SplashDisplay is made for this particular purpose, and given the nature of the display medium it pulls away from conventional standard surfaces. Given this trade-off, it is possible for the SplashDisplay to launch projectile beads from millimeters to meters into the air freely making it possible to attain an image ‘depth’ much like the Z-axis in 3D. In the simulation of ‘explosions’, this system launches beads into the air much like the physical phenomenon, making the projected object ‘feel’ like it actually exploded (Figure 1). As the beads are white in color, it is possible for these beads to act as a display backing. When the system is still, then the beads play the role of a stationary screen; once the beads are in air, they can still be recognized as ‘screen’ material. If light is projected onto these airborne beads, they will illuminate as they fall, giving a ‘fireworks’ like effect in real time.
