Abstract

Disclosed is a space perception device which includes a transceiver unit transmitting and receiving a signal; a processing unit analyzing signals transmitted and received through the transceiver unit to search location information of an obstacle at a space; and a vibration unit providing a user with location information of an obstacle at a space in response to a control of the processing unit. The vibration unit includes a plurality of vibrators having different three-dimensional coordinates.

Claims

1. A space perception device comprising:

a transceiver unit transmitting and receiving a signal;

a processing unit analyzing signals transmitted and received through the transceiver unit to search location information of an obstacle at a space; and

a vibration unit providing a user with location information of an obstacle at a space in response to a control of the processing unit,

wherein the vibration unit includes a plurality of vibrators having different three-dimensional coordinates.

2. The space perception device of claim 1, wherein the processing unit comprises:

a signal analyzing unit analyzing signals transmitted and received through the transceiver unit; and

a coordinate determining unit determining a three-dimensional coordinate on a location of an obstacle at a space, based on an analyzed result of the signal analyzing unit.

3. The space perception device of claim 2, further comprising:

a control unit controlling the coordinate determining unit,

wherein the control unit selects at least one of the plurality of vibrators by comparing a three-dimensional coordinate of the obstacle determined at the coordinate determining unit and three-dimensional coordinates of the plurality of vibrators.

4. The space perception device of claim 3, wherein the control unit varies a coordinate axis of the three-dimensional coordinate.

5. The space perception device of claim 1, wherein the plurality of vibrators provides a user with location information of an obstacle at a space through vibration.

6. The space perception device of claim 1, wherein the plurality of vibrators is formed of a piezoelectric element.

7. The space perception device of claim 1, wherein the transceiver unit transmits at least two transmission signals in different directions, and the at least two transmission signals transmitted in different directions have different modulation values.

8. The space perception device of claim 7, wherein the transceiver unit selectively receives signals corresponding to the at least two transmission signals transmitted in different directions according to a modulation value.

9. The space perception device of claim 8, wherein the transceiver unit includes an array of transmitters and receivers to transmit at least two transmission signals in different directions and to receive at least two transmission signals from different directions.

10. The space perception device of claim 1, wherein the transceiver unit includes first to third transceivers configured to be directed in different directions.

11. The space perception device of claim 10, wherein the first to third transceivers include first to third image collectors collecting images with respect to different directions, respectively.

12. The space perception device of claim 11, wherein the first to third image collectors measure focal distances on different images on the basis of an infrared ray.

13. The space perception device of claim 12, wherein when the first to third collectors collects the same image, the same images collected by the first to third collectors have different focal distances.

14. The space perception device of claim 1, further comprising:

a stick unit searching information associated with an obstacle on a footpath of a user.

15. The space perception device of claim 1, wherein the plurality of vibrators is configured to include a sensor measuring a function of the human body.

16. The space perception device of claim 1, wherein the processing unit includes a GPS device detecting information about a location of a user.
