Abstract

Embodiments are directed to an optical privatizing device ( 100 ), system and methods of use. The device includes a removable frame ( 101 ) removably attachable to a sensor housing ( 1 A). A device includes a blurring lens ( 130 ) coupled to the removable frame ( 101 ) and configured to optically modify light passing to a depth sensor wherein the optical modified light has a privatizing blur level to neutralize a profile of an object sensed by the depth sensor within a working volume of the depth sensor to an unidentifiable state while maintaining a depth parameter sensed by the depth sensor.

Claims (40)

1. A device comprising:

a removable frame removably attachable to a sensor housing; and

a blurring lens coupled to the removable frame and configured to optically modify light passing to a depth sensor wherein the optical modified light has a privatizing blur level to neutralize a profile of an object sensed by the depth sensor within a working volume of the depth sensor to an un-identifiable state while maintaining a depth parameter sensed by the depth sensor;

wherein the removable frame comprises:

a first side having a thickness, the first side including:

a first section having a first aperture having a closed state and an open state; and

a second section having a second aperture;

a second side perpendicularly coupled to an upper end of the first side;

a slot formed in the second side in proximity to the first section;

a channel in the first section; and

a removable panel removably coupled in the slot and supported in the channel to close the first aperture in the closed state; wherein in the closed state the panel blanks out light to the first aperture while the blurring lens simultaneously optically modifies the light passing to the depth sensor to the privatizing blur level, wherein:

the depth sensor is included in a video gaming device;

the frame being configured to be attached to the video gaming device such that the first aperture is in-line with a red, green, blue (RGB) sensor of the video gaming device; and

the device being devoid of electronic components.

2. The device of claim 1 , wherein the first section and the second section are side-by-side such that the first aperture is positioned at a distance from the second aperture, the first aperture has a circumference that allows light to pass through the first aperture, in the open state, to a lens of the RGB sensor.

3. The device of claim 1 , further comprising the depth sensor ( 675 ), wherein the blurring lens ( 677 ) to de-identify a thermal emitting object.

4. The device of claim 1 , wherein the blurring lens ( 130 ) being a function of a Gaussian Blur standard deviation factor to cause defocus blurring of the light passing through the blurring lens.

5. The device of claim 1 , wherein the blurring lens ( 130 ) being a function of a length of a target feature of the object degraded by the defocus blurring to neutralize the profile of the object.

6. The device of claim 5 , wherein the blurring lens ( 130 ) to de-identify faces and the length of the target feature includes a facial feature.

7. A system comprising:

an optical privatizing device; and

a multi-sensor device having a depth sensor with a working volume and a red, green, blue (RGB) sensor, the optical privatizing device includes:

a frame comprising first aperture to pass light to the RGB sensor and a second aperture;

a blurring lens coupled to the second aperture and to optically modify light to the depth sensor to a privatizing blur level to neutralize a profile of an object sensed by the depth sensor within the working volume to an un-identifiable state while maintaining a depth parameter sensed by the depth sensor; and

a panel selectively coupled to the frame to close the first aperture to blank-out the RGB sensor of the multi-sensor device while the blurring lens simultaneously optically modifies the light passing through the blurring lens,

wherein the frame comprises:

a first side having a thickness, the first side including:

a first section having the first aperture having a closed state and an open state; and

a second section having the second aperture; a second side perpendicularly coupled to an upper end of the first side;

a slot formed in the second side in proximity to the first section;

a channel in the first section; and

wherein the panel removably coupled in the slot and supported in the channel to close the first aperture in the closed state; wherein, in the closed state, the panel blanks out the light to the RGB sensor.

8. The system of claim 7 , wherein the first section and the second section are side-by-side such that the first aperture is positioned at a distance from the second aperture, the first aperture has a circumference that allows light to pass through the first aperture, in the open state, to a lens of the RGB sensor.

9. The system of claim 7 , wherein the blurring lens ( 130 ) being a function of a Gaussian Blur standard deviation factor to cause defocused blurring of the light passing through the blurring lens.

10. The system of claim 7 , wherein the blurring lens ( 130 ) being a function of a length of a target feature of the object degraded by the defocus blurring to neutralize the profile of the object.

11. The system of claim 10 , wherein the blurring lens ( 130 ) to de-identify faces and the length of the target feature includes a facial feature and the optical privatizing device ( 100 ) is devoid of electronic components.

12. The system of claim 7 , wherein:

the depth sensor is an infrared (IR) time-of-flight depth sensor;

the blurring lens ( 130 ) to de-identify a thermal emitting object; and

the optical privatizing device ( 100 ) is devoid of electronic components.
