Virtual input device and method for receiving user input using the same
First Claim
Patent Images
1. A virtual input device comprising:
- a first sensor configured to detect whether each of a plurality of hands is either a right hand or a left hand;
a processor configured to determine a virtual input layout based on the plurality of hands;
a projector configured to optically project the determined virtual input layout on a user input plane; and
a second sensor configured to detect a user input through the projected virtual input layout,wherein, when the plurality of hands comprise either two right hands or two left hands, the processor is further configured to determine to project a plurality of one-hand-support virtual input layouts as a two-hand-support virtual input layout, andwherein, when the plurality of hands comprise both a right hand and a left hand, the processor is further configured to determine to project a keyboard layout as the two-hand-support virtual input layout.

Abstract
A virtual input device using a projector and a method for receiving a user input using the same are provided. The virtual input device includes a first sensor configured to detect at least one user hand, a processor configured to determine a virtual input layout based on the detected at least one user hand, a projector configured to optically project the determined virtual input layout on a user input plane, and a second sensor configured to detect a user input through the projected virtual input layout.

12. A method for receiving a user input, the method comprising:
-
detecting whether each of a plurality of hands is either a right hand or a left hand; determining a virtual input layout based on the plurality of hands; optically projecting the determined virtual input layout on a user input plane; and detecting a user input through the projected virtual input layout, wherein the determining of the virtual input layout comprises; when the plurality of hands comprise either two right hands or two left hands, determining to project a plurality of one-hand-support virtual input layouts as a two-hand-support virtual input layout, and when the plurality of hands comprise both a right hand and a left hand, determining to project a keyboard layout as the two-hand-support virtual input layout. - View Dependent Claims (13, 14, 15, 16)
