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. The assistive device receives input to select a mode in the assistive device and based on the selected mode, determines each of a plurality of objects within a first proximity range of the assistive device as a relevant object or a non-relevant object to obtain a set of relevant objects and a set of non-relevant objects. The assistive device determines a scaling factor based on the first proximity range and the selected mode, and further adjusts sizes of the set of relevant objects to map the set of relevant objects with a set of haptic elements of the haptic feedback interface. The assistive device generates touch-discernible feedback on the haptic feedback interface to enable the user to non-visually discern the 3D real-world area surrounding the user.
