Collapsible projection assembly
First Claim
1. A collapsible projection assembly, comprising:
- a rotatable arm having at least one pivot point;
a projector that projects an image onto a surface;
a first sensor that detects the location of an input device in relation to the image; and
a second sensor that detects when the input device pierces a plane above the image;
wherein the rotatable arm is movable from a non-operational position to an operational position such that a predetermined spatial relationship between the projector, the first sensor and the second senor is at least substantially maintained when the rotatable arm reaches the operational position.

Abstract
The invention concerns a collapsible projection assembly (112) and a method (600) for operating same. The collapsible projection assembly can include a rotatable arm (116) having at least one pivot point (118), a projector (120) that can project an image (122) onto a surface (114), a first sensor (124) that can detect the location of an input device (128) in relation to the image and a second sensor (126) that can detect when the input device pierces a plane (130) above the image. The rotatable arm can be movable from a non-operational position to an operational position such that a predetermined spatial relationship between the projector, the first sensor and the second senor can be at least substantially maintained when the rotatable arm reaches the operational position.

15. A collapsible projection assembly, comprising:
-
a rotatable arm having at least one pivot point;
a locking mechanism, wherein the locking mechanism locks the rotatable arm in an operational position and permits the rotatable arm to move to a non-operational position;
a base, wherein the pivot point pivotably attaches the rotatable arm to the base;
a projector that projects an image onto a surface;
a first sensor that detects the location of an input device in relation to the image; and
a second sensor that detects when the input device pierces a predetermined plane above the image;
wherein the rotatable arm is movable from the non-operational position to the operational position such that a predetermined spatial relationship between the projector, the first sensor and the second senor is at least substantially maintained when the rotatable arm reaches the operational position and wherein the second sensor is incorporated in the base and the first sensor and the projector are incorporated in the rotatable arm.

16. A method of operating a collapsible projection assembly, wherein the collapsible projection assembly has a rotatable arm containing a pivot point and has a projector, a first sensor and a second sensor comprising:
-
moving the rotatable arm from a non-operational position to an operational position such that a predetermined spatial relationship between the projector, the first sensor and the second senor is at least substantially maintained when the rotatable arm reaches the operational position; and
projecting an image onto a surface from the projector. - View Dependent Claims (17, 18, 19, 20, 21)
