Claim Text:
1. A projector, comprising: a projection output to produce a frontal projection of a source image on a screen; a camera to capture an image of a reflection from the screen; a processor; and a memory storing instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising: overlaying the image of the reflection onto the source image; comparing an overlay of the image of the reflection to the source image; determining from the overlay a change in a depth of field; inferring, from the change in the depth of field, a presence of a human hand placed between the projection output and the screen; recognizing a gesture captured by the camera in the image of the reflection, the gesture performed by the human hand placed into a projection field of the source image, wherein the source image is compensated in response to the gesture; rotating the source image in response to the gesture performed by the human hand placed into the projection field; determining a distortion in the image of the reflection caused by the presence of the human hand placed between the projection output and the screen; and projecting a black silhouette from the projection output that overlaps the presence of the human hand in the source image, thus changing the distortion in the image of the reflection.
