论文摘要
早期的视觉到听觉替代设备将2D单眼图像编码为声音，而最近的设备则使用来自3D传感器的距离信息。这项研究评估了在最近的系统中增加声音编码距离是否有助于传达“位置”信息。这对于新的感觉替代设备的设计很重要。我们通过视觉替换系统进行了对象定位和导航任务的实验。它包括2D和3D模式。两者都实时编码对象在相机捕获的图像中的位置。 3D模式还编码系统与对象之间的距离。已经对16位蒙住眼睛的视力参与者进行了实验。对于本地化，参与者使用编码距离的3D模式更快地了解场景。另一方面，使用仅2D模式，他们能够弥补小训练后缺乏距离编码的。对于导航，与3D模式编码距离相比，参与者在2D模式下的表现良好。
Early visual to auditory substitution devices encode 2D monocular images into sounds while more recent devices use distance information from 3D sensors. This study assesses whether the addition of sound-encoded distance in recent systems helps to convey the "where" information. This is important to the design of new sensory substitution devices. We conducted experiments for object localization and navigation tasks with a handheld visual to audio substitution system. It comprises 2D and 3D modes. Both encode in real-time the position of objects in images captured by a camera. The 3D mode encodes in addition the distance between the system and the object. Experiments have been conducted with 16 blindfolded sighted participants. For the localization, participants were quicker to understand the scene with the 3D mode that encodes distances. On the other hand, with the 2D only mode, they were able to compensate for the lack of distance encoding after a small training. For the navigation, participants were as good with the 2D only mode than with the 3D mode encoding distance.
