Abstract
According to one embodiment, an information processor includes: a detector; a vector calculator; a determiner. The detector detects an object existing over a plurality of detection ranges set at distances different from one another from a reference surface and acquires representative points of the object based on detected position in the detection ranges. The vector calculator acquires a three-dimensional vector based on the representative points. The determiner determines an input operation by the object based on the three-dimensional vector.
Claims19
An information processor comprising:
- a detector which detects an object existing over a plurality of detection ranges set at distances different from one another from a reference surface and acquires representative points of the object based on detected position in the detection ranges;
- a vector calculator which acquires a three-dimensional vector based on the representative points;
- and
- a determiner which determines an input operation by the object based on the three-dimensional vector.
A processing method comprising:
- detecting an object existing over a plurality of detection ranges set at distances different from one another from a reference surface and acquiring representative points of the object based on detected position in the detection ranges;
- acquiring a three-dimensional vector based on the representative points;
- and
- determining an input operation by the object based on the three-dimensional vector.
A projection system comprising:
- a projector;
- a memory device for storing computer readable program code;
- and
- a processor in communication with the memory device, the processor being operative with the computer readable program code to
- detect an object existing over a plurality of detection ranges set at distances different from one another from a reference surface and acquire representative points of the object based on detected position in the detection ranges,
- acquire a three-dimensional vector based on the representative points, and
- determine an input operation by the object based on the three-dimensional vector.
