Abstract:
Methods, systems, and computer-readable media for generating a projected image are provided. Movement measurements are received from an accelerometer within a projection device. A determination is made as to whether the movement measurements indicate movement of the projection device. Upon determining that the movement measurements indicate movement of the projection device, a movement correction factor is determined based on the movement measurements to compensate for the movement of the projection device. The projection device is caused to generate a projected image according to the movement correction factor.
