Abstract：
UNASSIGNED: we present a preliminary set of experimental studies that demonstrates device-aided echolocation enabling in blind and visually impaired individuals. The proposed device emits a click-like sound into the surrounding space and returning sound is perceived by participants to infer the surrounding environment.
UNASSIGNED: two sets of experiments were set up to evaluate the echolocation abilities of nine blind participants. The first setup was designed to identify four material types based on the sound reflection properties of materials, such as glass, metal, wood, and ceramics. The second setup was navigation through a basic maze with the device.
UNASSIGNED: experimental data demonstrate that the use of the proposed device enables active echolocation abilities in blind participants, particularly for material identification and spatial mobility.
UNASSIGNED: the proposed device can potentially be used to rehabilitate disabled blind and visually impaired individuals in terms of spatial mobility and orientation.

摘要：
UNASSIGNED：我们提供了一组初步的实验研究，证明了设备辅助的回声定位功能可以在盲人和视力受损的人群中实现。所提出的设备向周围空间发出类似点击的声音，参与者感知到返回的声音以推断周围环境。
UNASSIGNED：建立了两组实验来评估9名盲人参与者的回声定位能力。第一个设置旨在根据材料的声音反射特性识别四种材料类型，比如玻璃,金属,木头,和陶瓷。第二个设置是使用该设备通过基本迷宫进行导航。
UNASSIGNED：实验数据表明，使用所提出的设备可以使盲人参与者具有主动回声定位能力，特别是材料识别和空间流动性。
UNASSIGNED：所提出的设备可能用于在空间移动性和取向方面恢复残疾盲人和视障人士。
设备有助于盲人和视障人士的康复在空间移动性和方向方面的康复可以使盲人和视障人士的积极回声定位。
