Abstract
The subject matter disclosed herein relates to determining a distance from a mobile device to a remote object or a size of the remote object.
Claims31
A method comprising:
- positioning an aperture through which to view a first point on a surface;
- adjusting an angle of rotation of a micro-reflector located a first distance from said aperture to direct energy toward said first point;
- calculating a distance to said surface using at least values of said first distance and said angle;
- determining a scaling factor of a mobile device, wherein said scaling factor is based at least in part on optical properties of said aperture;
- and
- determining a distance between two points on said surface using said scaling factor and said distance to said surface, wherein said determining said distance between two points on said surface further comprises:
- placing a scale on a display at said mobile device, said scale based at least in part on said scaling factor and said distance to said surface;
- and
- comparing said scale with an image of said surface to determine said distance between said two points on said surface.

An apparatus comprising:
- means for positioning an aperture through which to view a first point on a surface;
- means for adjusting an angle of rotation of a micro-reflector located a first distance from said aperture to direct energy toward said first point;
- means for calculating a distance to said surface using at least values of said first distance and said angle;
- means for determining a scaling factor for a mobile device, wherein said scaling factor is based at least in part on optical properties of said aperture;
- and
- means for determining a distance between two points on said surface using said scaling factor and said distance to said surface, wherein said means for determining said distance between two points on said surface further comprises:
- means for placing a scale on a display at said mobile device, said scale based at least in part on said scaling factor and said distance to said surface;
- and
- means for comparing said scale with an image of said surface to determine said distance between said two points on said surface.
6 more elements
An article comprising:
- a storage medium comprising machine-readable instructions stored thereon which, if executed by a computing platform, are adapted to enable said computing platform to:
- position an aperture through which to view a first point on a surface;
- adjust an angle of rotation of a micro-reflector located a first distance from said aperture to direct energy toward said first point;
- calculate a distance to said surface using at least values of said first distance and said angle;
- determine a scaling factor for a mobile device, wherein said scaling factor is based at least in part on optical properties of said aperture;
- and
- determine a distance between two points on said surface using said scaling factor and said distance to said surface, wherein said instructions, if executed by said computing platform, are further adapted to enable said computing platform to:
- place a scale on a display at said mobile device, said scale based at least in part on said scaling factor and said distance to said surface;
- and
- compare said scale with an image of said surface to determine said distance between said two points on said surface.
