I-Corps: ZeroTouch: High-Performance Sensing for Multi-Touch and Free-Air Interaction

所提出的技术是一种高性能的多指交互光电架构。随着计算资源变得廉价和无处不在，体现交互的重要性也在增加，这样人们就可以用身体向计算机表达自己，就像我们彼此交流一样。多点触摸和自由空间是体现交互的重要新感官形式。市场上的大多数多点触摸设备是使用电容式多点触摸感测技术的智能手机和平板电脑。然而，由于成本问题和技术挑战，这些技术不能很好地扩展到大型显示器。它们也不能感知戴手套的手指，从而排除了它们在许多应用场景中的使用。相比之下，所提出的努力涵盖了一种感测结构，该感测结构在缩放到大显示器时具有有竞争力的成本结构，随着显示器尺寸线性增加，而不是电容感测所表现出的成本的二次增加。该技术不需要实际的触摸，只需要中断传感平面，从而在汽车等新兴市场中实现戴手套的交互。它可以在户外阳光下工作，也可以在危险的条件下工作。它适用于电视，遥控操作和3D扫描。除了多点触摸感应，该技术还支持其他新的模式，如笔+触摸、触觉+触摸和自由空间交互。潜在市场的范围广泛而深入。所提出的技术可以改变体现互动对社会的影响。与大尺寸LCD的潜在集成可以改变用户在客厅和会议室中的媒体体验。团队的高精度和多指追踪？在面向社会创新的背景下，大格式的方法将使信息时代的工作场所、教育和家庭中计算机支持的合作工作和游戏的新形式得以发展。与汽车的集成将首先通过戴手套的手在小型控制面板上实现更轻松的交互;更多创新的解决方案将使用该平台在整个仪表板上进行交互，并使用挡风玻璃作为抬头显示器。如果成功商业化，该技术有可能开辟一系列新的广泛的工业应用。

The proposed technology is a high-performance optoelectronic architecture for multi-finger interaction. As computing resources grow cheap and ubiquitous, the importance of embodying interaction grows, so that people can express themselves to computers with their bodies, in the same rich ways that we communicate with each other. Multitouch and free-air are important new sensory modalities for embodied interaction. Most multi-touch devices on the market are smartphones and tablets using capacitive multi-touch sensing technologies. However, these technologies do not scale well to large displays because of cost issues and technological challenges. They also cannot sense gloved fingers, precluding their use in many application scenarios. In contrast, the proposed effort encompasses a sensing structure that has a competitive cost structure when scaled to large displays, increasing linearly with display size, as opposed to the quadratic increase in costs exhibited by capacitive sensing. The technology does not require actual touching, only interruption of a sensing plane, enabling gloved interaction in emerging markets such as automobiles. It can work outdoors in sunlight, and in hazardous conditions. It is suitable for TV, tele-operation and 3-D scanning. Beyond multi-touch sensing, the technology enables other new modalities, such as pen+touch, haptics+touch, and free-air interaction. The range of potential markets is wide and deep. The proposed technology can transform the impact of embodied interaction on society. Potential integration with large scale LCDs can transform users' experiences of media in living rooms and conference rooms alike. The high precision and many-finger tracking of the team?s approach in large formats in social innovation-oriented contexts will enable the development of new forms of Computer Supported Cooperative Work and Play in the information age workplace, education, and home. Integration with automobiles will first enable easier interaction by gloved hands on small control panels; more innovative solutions will use the platform for interaction across the whole dashboard, and using the windshield as a heads-up display. If successfully commercialized, the technology has the potential to open up a new broad array of industrial applications.
