Methods and systems for a virtual input device

摘要

The present application discloses systems and methods for a virtual input device. In one example, the virtual input device includes a projector and a camera. The projector projects a pattern onto a surface. The camera captures images that can be interpreted by a processor to determine actions. The projector may be mounted on an arm of a pair of eyeglasses and the camera may be mounted on an opposite arm of the eyeglasses. A pattern for a virtual input device can be projected onto a “display hand” of a user, and the camera may be able to detect when the user uses an opposite hand to select items of the virtual input device. In another example, the camera may detect when the display hand is moving and interpret display hand movements as inputs to the virtual input device, and/or realign the projection onto the moving display hand.

1. A method comprising:
receiving information indicative of an amount of movement of a head-mountable computing device; and determining that the indicated amount of movement is within a range of movement associated with the head-mountable computing device being substantially stationary and responsively:
providing, by a projector, an input device onto a surface, wherein the input device comprises a pattern of objects, and wherein the pattern of objects includes a plurality of regions;receiving, from a camera, an image of the input device;determining, by the head-mountable computing device, an approximate location of the surface based on a brightness level of the input device within the image of the input device;modifying a power of the projector to adjust brightness of a projection of the input device based on the brightness level indicating that a distance between the surface and the camera exceeds a predetermined threshold distance;highlighting a first region of the plurality of regions;detecting that a size of a second region increased relative to the first region; andhighlighting the second region instead of the first region.
