The digital replication of smell – so-called olfactory displays, remains one of the least advanced sensory technologies. Recent developments have focused heavily on virtual reality. However, there remains a need for olfactory displays targeted towards aroma training. In this paper, we present a thermal-based olfactory display, using Peltier heating elements. The unit is fully computer-controlled and holds up to 12 ‘aroma capsules’. Each capsule contains an individual aroma that can either be activated on its own or with others to create richer experiences. The unit has been designed as part of a wine aroma game to promote sensory training. The portable device has been tested with 15 volunteers to test the detection and recognition times of 6 aromas associated with red or white wines.

用于香气感官训练的基于热的嗅觉显示器的开发

气味的数字复制——所谓的嗅觉展示，仍然是最不先进的感官技术之一。最近的发展主要集中在虚拟现实上。然而，仍然需要针对香气训练的嗅觉展示。在本文中，我们展示了一种使用 Peltier 加热元件的基于热的嗅觉显示器。该装置完全由计算机控制，最多可容纳 12 个“芳香胶囊”。每个胶囊都包含一种独特的香气，可以单独激活或与其他人一起激活，以创造更丰富的体验。该单元被设计为葡萄酒香气游戏的一部分，以促进感官训练。该便携式设备已经与 15 名志愿者进行了测试，以测试与红葡萄酒或白葡萄酒相关的 6 种香气的检测和识别时间。
