Claim 20:
21. An assistive device, comprising:
a haptic feedback interface comprising a plurality of haptic elements;
a first circuitry configured to:
receive sensor data of a three-dimensional (3D) real-world area from a plurality of different types of sensors that are communicatively coupled to the assistive device,
wherein the sensor data is associated with a first proximity range of the assistive device, and
wherein the first proximity range corresponds to a template map of the 3D real-world area;
acquire weather conditions from one or more group of sensors from the plurality of different types of sensors;
assign a weigh value to each group of sensors of the one or more group of sensors based on accuracy of the sensor data detected in the acquired weather conditions, wherein in one or more of the weather conditions when the first sensor data is below a threshold value, a higher weigh value is assigned to the second sensor data as compared to the first sensor data;
process first sensor data received from a first group of sensors of the plurality of different types of sensors and second sensor data received from a second group of sensors of the plurality of different types of sensors based on the weigh value assigned to each of the first group of sensors and the second group of sensors;

a second circuitry configured to:
establish a mapping of a plurality of objects within the first proximity range to at least one haptic element of the plurality of haptic elements in a defined region of the haptic feedback interface, wherein the mapping of the plurality of objects within the first proximity range is established based on the processing of the first sensor data received from the first group of sensors and the second sensor data received from the second group of sensors; and
adjust sizes of the plurality of objects to map the plurality of objects to the at least one haptic element in a corresponding defined region of the plurality of defined regions, wherein the sizes of the plurality of objects are adjusted based on a scaling factor determined based on a surface area of the corresponding defined region; and

a haptic feedback generator configured to generate a touch-discernible feedback on the haptic feedback interface based on the established mapping,
wherein the touch-discernible feedback comprises a plurality of touch-discernible cues to discern a 3D arrangement of each object of the plurality of objects with respect to a position of a user of the assistive device, and
wherein the touch-discernible feedback corresponds to a differential temperature-based touch-discernible feedback.
