Holographic keyboard display

A keyboard interface system for displaying a holographic keyboard image and a holographic hand image representing a user's hand, the keyboard interface system comprising:

• a display system;
• a keyboard interface program executed by a processor of a computing device, the keyboard interface program configured to:
• receive depth information of an actual position of the user's hand;
• determine that the user's hand is spaced by an initial actual distance from a capture device that provides the depth information;
• display the holographic keyboard image spatially separated by a virtual distance from the holographic hand image;
• determine that the user's hand moves to an updated actual distance from the capture device;
• and
• in response to determining that the user's hand moves to the updated actual distance from the capture device, maintain the holographic keyboard image spatially separated by substantially the virtual distance from the holographic hand image.

A head-mounted display device for displaying a holographic keyboard image and a holographic hand image representing a user's hand, comprising:

• a display system;
• a computing device;
• and
• a keyboard interface program executed by a processor of the computing device, the keyboard interface program configured to:
• receive depth information of an actual position of the user's hand;
• determine that the user's hand is spaced by an initial actual distance from a capture device that provides the depth information;
• display the holographic keyboard image spatially separated by a virtual distance from the holographic hand image, wherein the holographic hand image forms an interaction angle with the holographic keyboard image;
• determine that an initial actual plane of the user's hand changes by a rotation angle to an updated actual plane;
• and
• in response, maintain the interaction angle between the holographic hand image and the holographic keyboard image.
