The aim of the project is to use recent advances in acoustic holography and high-performance computational techniques to create multimodal interactive applications that dynamically combine computational fabrication with visual, tactile, auditory, olfactory and gustatory experiences all using the same holography principles. The ambition of this project is to create systems that empower the design community to embrace the power of acoustic holography in creating applications that can create and manipulate both digitaland physical artefacts.Acoustic holography has shown its capability as Mixed-Reality (MR) displays in providing five modalities and its potential as a new computational fabrication technique that allows multi-material and multi-resolution 3D printing. However, due to computational limitations, such endeavours have been limited to one-modality at a time or one-off carefully orchestrated examples of combinations, and no holographic 3D fabrication has been demonstrated. A serious limitation in current approaches is in real-time computation of the sound fields that account for sound scatterings. This limitation is hindering our ability to make full use of the power of acoustic holography to create the plethora of applications that are ripe for exploitation.In this proposal, we will develop a real-time form-factor-agnostic sound field computation and explore optimum form factor to maximize users' multimodal experiences through several prototyping of interactive applications. The prototype applications will not only demonstrate the ability of acoustic holography to create magical experiences but will also provide easy-to-use tools for the community to integrate such systems in real-world applications. We will create an interactive application that blurs the boundary between displays and 3D printing where users can instantly 3D print physical prototypes and integrate them in an MR environment while going back-and-forth between 3D printing and MR-exploration.

该项目的目的是利用声全息和高性能计算技术的最新进展来创建多模态交互应用程序，这些应用程序动态地将联合收割机计算制造与视觉，触觉，听觉，嗅觉和味觉体验结合起来，所有这些都使用相同的全息原理。该项目的目标是创建一个系统，使设计界能够拥抱声全息的力量，在创建应用程序，可以创建和操纵数字和物理artefacts.Acoustic全息显示器的混合现实（MR）显示器提供五种模式和它的潜力，作为一种新的计算制造技术，允许多材料和多分辨率的3D打印。然而，由于计算的限制，这种努力一直局限于一次一种模态或一次性精心编排的组合示例，并且没有全息3D制造已经被证明。当前方法的一个严重限制是考虑声音散射的声场的实时计算。这种局限性阻碍了我们充分利用声全息技术的能力，从而创造出大量成熟的应用程序。在本提案中，我们将开发一种实时形状因子不可知的声场计算，并通过几种交互式应用程序的原型设计来探索最佳形状因子，以最大限度地提高用户的多模态体验。原型应用不仅将展示声全息术创造神奇体验的能力，还将为社区提供易于使用的工具，将此类系统集成到现实世界的应用中。我们将创建一个交互式应用程序，模糊显示器和3D打印之间的边界，用户可以立即3D打印物理原型并将其集成到MR环境中，同时在3D打印和MR探索之间来回切换。
