Abstract: A method for operating a head-mounted computing device that includes displaying an image of an environment on a display of the head-mounted computing device and identifying a surface within the image that is eligible for color fill operation, based on similarities in color parameters of contiguous pixels in the captured image. The method further includes displaying an indicator prompting user input regarding color fill, receiving a color fill request via user input, the request being for a predetermined color, and performing a color fill operation on the identified surface in response to receiving the color fill request by (a) generating a fill image having the predetermined color and a shape that conforms to the shape of the identified surface, and (b) displaying the fill image in a world-locked manner so as to overlay the identified surface even when a perspective of the display changes.

Abstract: A method for operation a head-mounted computing device that includes capturing an image of a three-dimensional environment external to the head-mounted computing device and identifying a surface within the captured image that is eligible for color fill operation, based on similarities in color parameters of contiguous pixels in the captured image. The method further includes receiving a color fill request via user input at the head-mounted computing device, the request being for a predetermined color and performing a color fill operation on the identified surface in response to receiving the color fill request by (a) generating a fill hologram having the predetermined color and a shape that conforms to the shape of the identified surface, (b) displaying the fill hologram in a world-locked manner so as to overlay the identified surface as viewed through the see-through holographic display of the head-mounted display device.
