1. An assistive device, comprising:
a haptic feedback interface that comprises a plurality of haptic elements; and
a haptic feedback controller configured to:
generate a touch-discernible output layout on the haptic feedback interface based on the plurality of haptic elements, wherein the touch-discernible output layout corresponds to a reproduction of a three-dimensional (3D) real-world area within a proximity range of the assistive device;
generate a set of different haptic indicators that are spatially arranged on the haptic feedback interface to discern a set of moving objects of the 3D real-world area within the proximity range, wherein the touch-discernible output layout includes the set of different haptic indicators;
receive a user input via the haptic feedback interface; and
track a movement of a target moving object of the set of moving objects in the 3D real-world area based on the received user input.
