Abstract: A component in a horizontal direction (the x-axis component) of a movement amount first acquired after a pointing device is reset and a component in a vertical direction (the y-axis component) are compared, a movement input is regarded as provided only in the horizontal direction in case the absolute value of the x-axis component is larger than the absolute value of the y-axis component, a movement input is regarded as provided only in the vertical direction in case the absolute value of the y-axis component is larger than the absolute value of the x-axis component, a movement input is regarded as provided in the same direction unless the ratio of components of movement inputs is greatly changed subsequently, and continuous movement inputs in the same direction are facilitated.

Abstract: A system for adjusting keystoning in a projector may include sensing using an imaging device at least two boundaries defining a projection screen and determining a transformation to adjust the keystoning of an image projected from the projector. The image may be modified from the projector in accordance with the transformation and projecting the modified image from the projector, wherein the imaging device and the projector are maintained in a fixed relationship with respect to each other.

Abstract: An image projection system that corrects an image to be projected onto a projection surface by sensing at least a portion of that surface, and based upon the sensed portion, determining and applying a corrective transformation to the image, after which the corrected image is projected onto the projection surface.

Abstract: In a display apparatus for presentation including an image display device 30 that allows for moving a selection marker across a plurality of menu items arranged in vertical and horizontal directions and displayed on a screen 1 in accordance with received angular velocity information, a menu item to which the selection marker should be moved is determined in accordance with the number of cycles of angular velocity sampling during which the move distance of the pointing device obtained for every sampling cycle from the angular velocity information exceeds a predetermined value continuously. This improved the inconvenience to use with a conventional pointing device in which a distance by which an object should be moved on the display screen is proportional to the entire distance over which the pointing device was moved, calculated from angular velocity; thus, the operator has to tilt the remote controller incorporating a gyroscope to a large extent to move the object by a long distance on the screen.
