Abstract
Apparatuses and methods enhance depth perception, e.g., the depth perception of a human being using an apparatus worn on the user's head.
Claims11
An apparatus comprising
- a frame configured to be worn on a human head;
- a rangefinder mechanism configured to measure a distance of an object, the rangefinder mechanism comprising:
- a transmitter of a reflectable signal,
- a receiver of the reflectable signal, and
- output circuitry configured to transmit a distance signal indicative of a location of the object,
- wherein the rangefinder mechanism attached to the frame and oriented such that the transmitter of the reflectable signal emits the reflectable signal in a direction parallel to a line of sight of the eyes of a user wearing the frame;
- a transducer configured to receive the distance signal from the rangefinder mechanism and configured to transmit an audio signal;
- and
- a speaker configured to receive the audio signal and to emit an audible tone, the speaker attached to the frame.

A method, comprising
- measuring a distance of an object by emitting a reflectable signal in a direction parallel to a line of sight of eyes of a user wearing a frame configured to be worn on a human head;
- generating a distance signal indicative of a location of the object, the distance signal based on the reflectable signal;
- generating an audio signal based on the distance signal;
- and
- emitting an audible tone corresponding to the audio signal.
