Abstract:
A method, non-transitory computer readable medium, and apparatus for providing a dimension and a proximity of an object are disclosed. For example, the method receives a three dimensional depth map expressed as a two dimensional array of gray values, rasterizes the two dimensional array of gray values into vertical scan lines and horizontal scan lines for a left speaker and a right speaker and converts the vertical scan lines and the horizontal scan lines into a double beep, wherein a first beep of the double beep represents a vertical dimension of the object, the second beep of the double beep represents a horizontal dimension of the object, an intensity of each beep of the double beep represents the proximity of the object and a frequency spectrum of the double beep represents a shape of the object.
