Abstract / Hauptanspruch
A wearable device, having a camera and a light source, receives user inputs by a first method of measuring a height of a finger-like object's tip above a reference surface if this surface is present, or a second method of estimating a 3D location of the tip. In the first method, a plain sheet of light is projected to the object, casting a shadow on the surface. A camera-observed shadow length is used to compute the tip's height above the surface. In the second method, the nearest and farthest locations of the tip are estimated according to pre-determined lower and upper bounds of the object's physical width. The object is then illuminated with a structured-light pattern configured such that an area between the nearest and farthest locations receives a portion of the pattern where this portion does not contain a repeated sub-pattern, enabling unique determination of the tip's 3D location.
