对于盲人来说，空间感知是一项具有挑战性的任务，因为手的功能和感知范围有限。我们提出了GIST，一个可穿戴的手势接口，提供空间感知功能，通过新颖的拨款用户的手到多功能的传感棒。使用可穿戴深度传感相机，GIST分析可见的物理空间，并允许盲人用户使用不同的手势访问有关该空间的空间信息。通过允许盲人用户使用手势直接探索物理空间，GIST允许增强现实和物理现实之间最接近的映射，从而促进空间交互。一项针对8名盲人用户的用户研究评估了GIST帮助执行依赖于空间感知的日常任务的能力，例如抓取物体或与人互动。我们的研究结果可能有助于开发新的基于手势的辅助应用。
Spatial perception is a challenging task for people who are blind due to the limited functionality and sensing range of hands. We present GIST, a wearable gestural interface that offers spatial perception functionality through the novel appropriation of the user's hands into versatile sensing rods. Using a wearable depth-sensing camera, GIST analyzes the visible physical space and allows blind users to access spatial information about this space using different hand gestures. By allowing blind users to directly explore the physical space using gestures, GIST allows for the closest mapping between augmented and physical reality, which facilitates spatial interaction. A user study with eight blind users evaluates GIST in its ability to help perform everyday tasks that rely on spatial perception, such as grabbing an object or interacting with a person. Results of our study may help develop new gesture based assistive applications.
