The recent COVID19 outbreak has shown that touching buttons in a public space presents risks of viral spread. Buttons pervade public spaces, from toilet flushing, and elevator controls to keypads on ATM's. TruLife Optics wants to use its expertise as a world leader in holography to make such interfaces safe, by developing holograms that project the image of a button or a key pad in mid-air, so users can interact with such floating images twinned with a sensor, avoiding touching any physical surface.Currently, contact-free infrared sensors have the disadvantage that they do not provide a visual cue, i.e., they do not show where to swipe nor when they have been activated. Think about how difficult it can be to use a water tap in a public toilet! TruLife Optics will develop a novel hologram prototype that generate a floating image of two lift call buttons. These buttons will be shown in a U shaped display with light and sensor. The hologram will be seen to float in mid air - 4 cm from the floor of the unit (meaning it will be hard to touch the physical surface). A finger sensor will detect which of the up or down buttons has been pressed and an audio indication of up or down will be given.The holograms will be designed so that the buttons can be easily seen from a wide range of viewpoints. Also, when coming closer, one or several buttons , or numbers will indicate exactly where to press or swipe. The image to be projected, i.e., a button, a keypad, an arrow, or a combination of these, can be adapted quite straightforwardly to the application in mind. The first laboratory prototypes will focus on showing a single interactive entity, i.e., a button,In later stages (not part of this funding) we will have feedback on the holograms themselves. The hologram can be illuminated by two LED's with different colours, e.g., a green and a red light. As a result, the colour of the button is an indication of whether is it on or off. We are in touch with sensor suppliers to evaluate how to pair the sensor with the hologram.A second generation will build upon the idea of the floating button, i.e., it will generate a numeric floating keypad, like those on an ATM machine, twinned with a commercially available finger tracking sensor. We will build a demo showing numbers appearing on a screen as the floating keypad is "pressed" in mid air.We have multiple enquiries from potential customers and we have a partnership with a leading sensor company who wants to co-develop the technology and twin our holograms with their sensors and then market to all their customers.

最近的Covid19爆发表明，公共空间中的接触按钮具有病毒蔓延的风险。纽扣遍布公共空间，从洗手间冲洗，电梯控件到ATM上的键盘。 Trulife Optics希望通过开发全息图，以在空气中间的纽扣或钥匙垫中投射图像或钥匙垫，因此用户可以与传感器互动，避免接触到任何视觉，它们不提供任何视觉，他们不提供任何直觉，因此它们不提供任何视觉，因此，他们可以与脱落。当它们被激活时。考虑一下在公共厕所中使用水龙头的困难！ Trulife Optics将开发一种新型的全息原型，该原型生成两个升降机按钮的浮动图像。这些按钮将显示在带有光和传感器的U形显示器中。全息图将被视为距离设备地板4厘米的空气中漂浮（这意味着很难接触物理表面）。手指传感器将检测到哪个上或向下按钮已被按下，并给出向上或向下的音频指示。全息图将设计为可以从广泛的观点中轻松看到按钮。另外，靠近时，一个或几个按钮或数字将准确指示在哪里按下或滑动。要投影的图像，即一个按钮，键盘，箭头或这些组合的图像，可以非常简单地适应应用程序。第一个实验室原型将集中于显示一个单一的交互式实体，即按钮，在以后的阶段（不是资金的一部分），我们将对全息图本身有反馈。全息图可以用两种LED照亮，例如绿色和红灯。结果，按钮的颜色表明它是打开还是关闭。我们与传感器供应商保持联系，以评估如何将传感器与全息图配对。第二代将基于浮动按钮的想法，即，它将产生一个数字浮动键盘，例如在ATM机上，在ATM机上，用商业上可用的手指跟踪传感器进行了双胞胎。我们将在屏幕上构建一个演示，显示出在屏幕上出现的数字，因为浮动键盘在中间空气中被“压”。我们对潜在客户进行了多次查询，并且我们与一家领先的传感器公司建立了合作伙伴关系，他们希望共同开发该技术并与传感器进行双胞胎，然后向所有客户进行营销。
