Abstract:
1. A method for generating a projected image, the method comprising: determining, by a processor, a full field of view of a projection device positioned at a baseline location, the full field of view corresponding to a first area capable of being projected by the projection device at the baseline location, the full field of view positioned at a first location corresponding to the baseline location of the projection device; determining, by the projection device, a limited field of view of the projection device positioned at the baseline location, the limited field of view corresponding to a second area that is smaller than the first area, the limited field of view positioned at the first location corresponding to the baseline location of the projection device, wherein a difference between the full field of view and the limited field of view represents an error tolerance of a movement correction factor, the projection device at the baseline location generating a projected image corresponding to the baseline location, the projected image positioned within the full field of view and at least partially outside of the limited field of view; receiving, by the processor, movement measurements from an accelerometer within the projection device; determining, by the processor, that the movement measurements indicate movement of the projection device to a location different from the baseline location, wherein the full field of view and the limited field of view are positioned at a second location corresponding to the location of the projection device different from the baseline location, the projection device at the location different from the baseline location generating the projected image within the full field of view positioned at the second location and at least partially outside of the limited field of view positioned at the second location; determining, by the processor, whether projection of a corrected image of the projected image based on the movement correction factor to compensate for movement of the projection device to the location different from the baseline location is at least partially outside of the full field of view positioned at the second location; and if projection of the corrected image of the projected image based on the movement correction factor is determined to be at least partially outside of the full field of view, causing, by the processor, the projection device to generate the projected image corresponding to the location of the projection device different from the baseline location without correction.
