Abstract
A method for displaying a series of images on a projection screen as a function of a position of a presenter in front of the projection screen. First, the width of the screen is divided into a number of segments of selected widths. The positions of each of the segments is stored in a memory. The position of the presenter is compared with the stored segments to identify the segment currently occupied by the presenter. An image control signal is generated when the presenter changes position from a first segment to a second segment
Claims17
A method for displaying a series of images on a projection screen as a function of a position of a presenter in front of said projection screen comprising the steps of:
- a) dividing the width of the screen into a number of segments of selected widths and storing the positions of each of said segments in a memory,
- b) comparing the position of said presenter with said stored segments to identify the segment currently occupied by said presenter,
- c) generating an image control signal when said presenter changes position from a first segment to a second segment.
A method by which an image on a projection screen is changed when a presenter changes position in front of said screen from a first position to a second position comprising the steps of:
- a) storing in a memory positional identifying information for a plurality of segments, each segment having a designated position on said screen,
- b) comparing the position of said presenter with said positional identifying information to identify the segment currently occupied by said presenter,
- c) enabling said image change when said presenter has moved from a current segment to an adjacent segment.
