摘要： An assistive device and method for non-visually discerning a three-dimensional (3D) real-world area surrounding a user, comprises a haptic feedback interface that includes a plurality of haptic elements. The assistive device receives sensor data of the 3D real-world area within a first proximity range of the assistive device from a plurality of different types of sensors that are communicatively coupled to the assistive device. The assistive device establishes a mapping of a plurality of objects within the first proximity range to the plurality of haptic elements in a defined region of the haptic feedback interface, based on the received sensor data. A haptic feedback generator generates a touch-discernible feedback on the haptic feedback interface based on the established mapping. The touch-discernible feedback comprises a plurality of differential touch-discernible cues to enable the user to non-visually discern the 3D real-world area surrounding the user.
