Abstract
A combiner that reflects a light projected by a projector toward an operator, includes: a reflection layer that reflects the light projected by the projector; an electric field generation layer that generates an electric field around the combiner; and an output layer that outputs a voltage according to change of the electric field generated by the field generation layer.
Claims5
A combiner that reflects a light projected by a projector toward an operator, comprising:
- a reflection layer that reflects the light projected by the projector;
- an electric field generation layer that generates an electric field around the combiner;
- and
- an output layer that outputs a voltage according to change of the electric field generated by the field generation layer.

An operation detection device comprising:
- a combiner that reflects a light projected by a projector toward an operator;
- and
- a judgment device;
- the combiner including:
- a reflection layer that reflects the light projected by the projector;
- an electric field generation layer that generates an electric field around the combiner;
- and
- an output layer that outputs a voltage according to change of the electric field generated by the field generation layer;
- and
- the judgment device including:
- a voltage supply circuit that supplies a voltage to the electric field generation layer;
- a voltage input circuit that inputs a voltage from the output layer;
- and
- a detector that detects a non-contact operation content by the operator based on a signal corresponding to a difference between the voltage supplied to the electric field generation layer and the voltage from the output layer.
