我们提出了一种新的嗅觉显示系统，可以产生一个二维显示屏幕上的气味分布。所提出的系统在屏幕的四个角上具有四个风扇。由这些风扇产生的气流多次碰撞以产生从屏幕上的特定位置朝向用户的气流。通过将气味蒸汽引入气流中，气味分布就好像气味源被放置在屏幕上一样。所产生的气味分布使用户感觉到气味是从屏幕的特定区域发出的。通过调节来自四个风扇的气流的平衡，可以将该虚拟气味源的位置移动到屏幕上的任意位置。大多数用户不会立即注意到所提出的嗅觉显示系统的气味呈现机制，因为气流和感知到的气味来自显示屏而不是风扇。气流速度甚至可以被设置为低于气流感觉的阈值，使得用户仅感知到气味。我们目前的实验结果表明，所提出的系统产生的气流场和气味分布。我们还报告了感官测试结果，以显示所产生的气味分布是如何被用户感知的，以及在气味呈现中必须考虑的问题。
We propose a new olfactory display system that can generate an odor distribution on a two-dimensional display screen. The proposed system has four fans on the four corners of the screen. The airflows that are generated by these fans collide multiple times to create an airflow that is directed towards the user from a certain position on the screen. By introducing odor vapor into the airflows, the odor distribution is as if an odor source had been placed onto the screen. The generated odor distribution leads the user to perceive the odor as emanating from a specific region of the screen. The position of this virtual odor source can be shifted to an arbitrary position on the screen by adjusting the balance of the airflows from the four fans. Most users do not immediately notice the odor presentation mechanism of the proposed olfactory display system because the airflow and perceived odor come from the display screen rather than the fans. The airflow velocity can even be set below the threshold for airflow sensation, such that the odor alone is perceived by the user. We present experimental results that show the airflow field and odor distribution that are generated by the proposed system. We also report sensory test results to show how the generated odor distribution is perceived by the user and the issues that must be considered in odor presentation.
