Projection control apparatus and projection control method

A projection control method comprising:

• projecting an image;
• detecting at least one of a first user operation and a second user operation;
• changing projection parameters of the image upon detecting the first user operation;
• changing the image without changing the projection parameters upon detecting the second user operation;
• recognizing a specific region of a user based on information obtained from a sensor to obtain region position information indicating a position of the recognized specific region;
• obtaining projection position information indicating a position where at least part of a projection image plane is projected, based on the obtained sensor information;
• and
• detecting at least one of the first user operation and the second user operation based on the region position information and the projection position information.

A non-transitory computer-readable storage medium storing instructions that when executed by a computer enable the computer to implement a method comprising:

• projecting an image;
• detecting at least one of a first user operation and a second user operation;
• changing projection parameters of the image upon detecting the first user operation;
• changing the image without changing the projection parameters upon detecting the second user operation;
• recognizing a specific region of a user based on information obtained from a sensor to obtain region position information indicating a position of the recognized specific region;
• obtaining projection position information indicating a position where at least part of a projection image plane is projected, based on the obtained sensor information;
• and
• detecting at least one of the first user operation and the second user operation based on the region position information and the projection position information.
