Abstract
An optical device combination with a portable electronic device utilizes a user's autonomic response to truth/false or beneficial/non-beneficial stimulus and provides immediate feedback to the user in the context of an applied kinesiology exam. Through measurements of the pupils dilation or constriction and processing of the measurements by the portable electronic device, the response is obtained and feedback is provided that reflects the pupillary response. The device and method effectively eliminate the subjective components of prior art muscle testing response from the hands of the testing user as well as providing a simple convenient and portable attachment to a user's smart phone.
Claims20
An imaging system for capturing images of a user's eye, comprising:
- a light source, said light source positioned to illuminate the iris of the user's eye;
- a first polarizing filter, said first polarizing filter positioned between the light source and the user's eye and emits light with a first polarization;
- an analyzer filter, said analyzer filter blocking light with the first polarization;
- a partial light reflector, said light reflector disposed proximate and substantially normal to an optical axis of the user's eye, said partial light reflector positioned to reflect a mirror image of the user's eye towards the user's eye;
- an image recorder, said image recorder positioned to capture images of the user's iris;
- an image processor connected to the image recorder;
- and
- a display unit, said display unit operable connected to the image processor.
A optical device configured to attach to a portable electronic device for observing and capturing an image of the user's eye, comprising:
- a housing having a first end with a first opening and a second end with a second opening;
- a light passage;
- a light source positioned proximate to the first end;
- a polarizing filter positioned to receive light emitted from the light source and provide light to the user's eye with a first polarization;
- an analyzing filter intersecting the light passage, the analyzing filter blocking light with a first polarization from passing;
- a beam splitter, said beam splitter projects a portion of the light incident upon it through the second opening and a mirror image of the user's eye thru the first opening to the user's eye;
- and,
- a clip configured to removably attach the optical device to the portable electronic device and to align the second opening with a lens of a digital camera when the optical device is attached to the portable electronic device;
- wherein the light passage extends from the first opening through the analyzing filter, the beam splitter and the second opening, wherein the beam splitter is co-axial with the light passage.
A method of measuring the response of a user's eye to a stimulus, comprising:
- a. providing an optical device having a first end and a second end;
- b. aligning the first end to the user's eye;
- c. aligning the second end to a digital camera associated with a portable electronic device;
- d. applying a stimulus to the user;
- e. recording an image of the user's eye with the digital camera and reflecting a mirror image of the user's eye through the first end to the user's eye contemporaneous with the application of a stimulus;
- wherein the recording and reflecting are performed simultaneously;
- f. processing the captured image to obtain a measurement of a characteristic of the user's eye, wherein the processing is by a processor in the portable electronic device;
- g. comparing the measurement with a predetermined measurement in the processor;
- h. determining the user's response in the processor based on the comparison;
- and,
- i. providing an indication of the user's response to the user via the portable electronic device.
