Abstract

Claims (53)

1 . A system comprising:

a wearable head device comprising:

an image light source;

one or more sensors; and

a partially reflective surface positioned to receive image light from the image light source; and

one or more processors configured to perform a method comprising:

determining an operation mode based on a signal received by the one or more sensors;

causing the image light source to present image light, via the partially reflective surface, toward a user of the wearable head device;

in accordance with a determination that the operation mode comprises a first operation mode, capturing, via the one or more sensors at a first rate, reflected light comprising a reflection of the presented image light;

in accordance with a determination that the operation mode comprises a second operation mode, capturing, via the one or more sensors at a second rate different from the first rate, reflected light comprising the reflection of the presented image light; and

monitoring a health of the user based on the captured reflected light.

2 . The system of claim 1 , wherein said monitoring the health of the user comprises detecting a health event.

3 . The system of claim 2 , wherein the health event comprises one or more of a concussion, a brain injury, a stroke, and blood loss.

4 . The system of claim 1 , wherein:

said presenting the image light toward the user comprises presenting the image light via a first optical path; and

the reflection of the presented image light comprises a reflection of the image light toward the one or more sensors along a second optical path at least partially collinear with the first optical path.

5 . The system of claim 1 , wherein:

said presenting the image light toward the user comprises presenting the image light via a first optical path; and

the reflection of the presented image light comprises a reflection of the image light toward the one or more sensors along a second optical path not collinear with the first optical path.

6 . The system of claim 1 , wherein the method further comprises:

determining that the wearable head device has been removed from the user; and

in response to the determination, forgoing causing the image light source to present the image light.

7 . The system of claim 1 , wherein said presenting the image light comprises presenting light outside of a visible spectrum.

8 . The system of claim 1 , wherein said determining the operation mode is further based on a health characteristic of the user, wherein the health characteristic comprises one or more of a heart rate, a blink rate, a blood glucose level, a hemoglobin level, and a presence of a first substance in the user's blood.

9 . The system of claim 1 , wherein the one or more sensors comprises a camera.

10 . A method comprising:

determining an operation mode based on a signal received by one or more sensors of a wearable head device, the wearable head device comprising an image light source and a partially reflective surface positioned to receive image light from the image light source;

presenting image light, via the image light source and further via the partially reflective surface, toward a user of the wearable head device;

in accordance with a determination that the operation mode comprises a first operation mode, capturing, via the one or more sensors at a first rate, reflected light comprising a reflection of the presented image light;

in accordance with a determination that the operation mode comprises a second operation mode, capturing, via the one or more sensors at a second rate different from the first rate, reflected light comprising the reflection of the presented image light; and

monitoring a health of the user based on the captured light.

11 . The method of claim 10 , wherein said monitoring the health of the user comprises detecting a health event.

12 . The method of claim 11 , wherein the health event comprises one or more of a concussion, a brain injury, a stroke, and blood loss.

13 . The method of claim 10 , wherein:

said presenting the image light toward the user comprises presenting the image light via a first optical path; and

the reflection of the presented image light comprises a reflection of the image light toward the one or more sensors along a second optical path at least partially collinear with the first optical path.

14 . The method of claim 10 , wherein:

said presenting the image light toward the user comprises presenting the image light via a first optical path; and

the reflection of the presented image light comprises a reflection of the image light toward the one or more sensors along a second optical path not collinear with the first optical path.

15 . The method of claim 10 , further comprising:

determining that the wearable head device has been removed from the user; and

in response to the determination, forgoing presenting the image light.

16 . The method of claim 10 , wherein said presenting image light comprises presenting light outside of a visible spectrum.

17 . The method of claim 10 , wherein said determining the operation mode is further based on a health characteristic of the user, wherein the health characteristic comprises one or more of a heart rate, a blink rate, a blood glucose level, a hemoglobin level, and a presence of a first substance in the user's blood.

18 . The method of claim 10 , wherein the one or more sensors comprises a camera.

19 . A non-transitory computer-readable storage medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform a method comprising:

determining an operation mode based on a signal received by one or more sensors of a wearable head device, the wearable head device comprising an image light source and a partially reflective surface positioned to receive image light from the image light source;

presenting image light, via the image light source and further via the partially reflective surface, toward a user of the wearable head device;

in accordance with a determination that the operation mode comprises a first operation mode, capturing, via the one or more sensors at a first rate, reflected light comprising a reflection of the presented image light;

in accordance with a determination that the operation mode comprises a second operation mode, capturing, via the one or more sensors at a second rate different from the first rate, reflected light comprising the reflection of the presented image light; and

monitoring a health of the user based on the captured light.

20 . The non-transitory computer-readable storage medium of claim 19 ,

wherein said monitoring the health of the user comprises detecting a health event.
