在本文中，我们提出了我们的可穿戴感觉替代系统ProximityHat，它使用头部周围的压力致动器来传达空间信息的迭代设计过程。已经表明触觉可以用来增强我们对现实的感知。现有的系统集中在振动信号的信息传输，但这是不适合在日常使用中的持续刺激。我们的系统通过超声波传感器确定与周围物体的距离，并将此信息映射到向内的压力。在一项研究中，13名受试者在方向和导航任务进行了评估。用户能够高度确定地辨别至少三种不同的绝对压力水平。结合传感器，它们还可以使用连续值来导航走廊和找到门。大多数用户只有几次碰撞，但一小群三个人挣扎得更多。我们将其归因于最终原型的延迟和分辨率，这导致了缓慢的行走速度，并将在未来的工作中解决。
In this paper we present the iterative design process of our wearable sensory substitution system ProximityHat, which uses pressure actuators around the head to convey spatial information. It was already shown that the sense of touch can be used to augment our perception of reality. Existing systems focus on vibration signals for information transfer, but this is unsuitable for constant stimulation in everyday use. Our system determines the distance to surrounding objects with ultrasonic sensors and maps this information to an inward pressure. It was evaluated in a study with 13 blindfolded subjects in orientation and navigation tasks. The users were able to discern at least three different absolute pressure levels with high certainty. Combined with the sensors, they could also use continuous values to navigate hallways and find doors. Most users had only a few collisions, but a small group of three individuals struggled more. We attribute this to the latency and resolution of the final prototype, which led to slow walking speed and will be addressed in future work.
