摘要

We propose a novel graphics system based on the expansion ofrn3D acoustic-manipulation technology. In conventional research onrnacoustic levitation, small objects are trapped in the acoustic beamsrnof standing waves. We expand this method by changing the distributionrnof the acoustic-potential field (APF). Using this technique,rnwe can generate the graphics using levitated small objects. Our approachrnmakes available many expressions, such as the expressionrnby materials and non-digital appearance. These kinds of expressionsrnare used in many applications, and we aim to combine themrnwith digital controllability. In the current system, multiple particlesrnare levitated together at 4.25-mm intervals. The spatial resolutionrnof the position is 0.5 mm. Particles move at up to 72 cm/s. The allowablerndensity of the material can be up to 7 g/cm~3. For this study,rnwe use three options of APF: 2D grid, high-speed movement, andrncombination with motion capture. These are used to realize floatingrnscreen or mid-air raster graphics, mid-air vector graphics, andrninteraction with levitated objects. This paper reports the details ofrnthe acoustic-potential field generator on the design, control, performancernevaluation, and exploration of the application space. Torndiscuss the various noncontact manipulation technologies in a unifiedrnmanner, we introduce a concept called “computational potentialrnfield” (CPF).
