[Solution] The information processing apparatus includes a controller configured to perform processing of outputting feedback indicating an effect corresponding to a boundary of a drivable region of a drive-type projector in a projection environment space in accordance with a state of a projection specification position specified by a user for the drivable region, the state being determined based on the drivable region and the projection specification position. ## Claims ### Claim 1 An information processing apparatus comprising a controller configured to perform processing of outputting feedback indicating an effect corresponding to a boundary of a drivable region of a drive-type projector in a projection environment space in accordance with a state of a projection specification position specified by a user for the drivable region, the state being determined based on the drivable region and the projection specification position. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein the state that is determined includes a distance between the projection specification position and the boundary, and the controller controls intensity of the effect in accordance with the distance between the projection specification position and the boundary. ### Claim 3 (depends on 2) The information processing apparatus according to claim 2, wherein the controller performs the feedback by reflecting the effect in accordance with the determined state to a projection image, sound output, drive control of the drive-type projector, or vibration control of an input device of the projection specification position. ### Claim 4 (depends on 3) The information processing apparatus according to claim 3, wherein the controller intensifies the effect as the distance between the projection specification position and the boundary in the vicinity of the projection specification position is shorter in a state where the projection specification position is located inside the drivable region. ### Claim 5 (depends on 4) The information processing apparatus according to claim 4, wherein the controller changes a shape or a color tone of a pointer image or a content image projected onto the projection specification position, as the effect. ### Claim 6 (depends on 5) The information processing apparatus according to claim 5, wherein the controller decreases a size of the pointer image or the content image projected at the projection specification position or causes the pointer image or the content image to wane as the projection specification position becomes closer to the boundary, as the effect. ### Claim 7 (depends on 5) The information processing apparatus according to claim 5, wherein the controller does not display a portion of a region of the pointer image or the content image that is located outside the boundary, as the effect. ### Claim 8 (depends on 5) The information processing apparatus according to claim 5, wherein when the pointer image or the content image is close to the boundary and reaches the boundary, the controller performs display in which the pointer image or the content image hits the boundary and swings, display in which a color tone of the pointer image or the content image is changed, display in which the pointer image or the content image flashes, or display in which the pointer image or the content image rebounds, as the effect. ### Claim 9 (depends on 5) The information processing apparatus according to claim 5, wherein the controller changes a color tone of a portion of a region of the pointer image or the content image that is located outside the boundary, as the effect. ### Claim 10 (depends on 5) The information processing apparatus according to claim 5, wherein the controller changes a drawing position in a projection image such that the pointer image or the content image does not protrude outside the boundary, as the effect. ### Claim 11 (depends on 4) The information processing apparatus according to claim 4, wherein the controller displays an undrivable region as a region outside the boundary, as the effect. ### Claim 12 (depends on 11) The information processing apparatus according to claim 11, wherein the controller intensifies a color tone of the undrivable region as the projection specification position becomes closer to the boundary. ### Claim 13 (depends on 1) The information processing apparatus according to claim 1, wherein the controller displays a bird's-eye view image of the projection environment space that indicates a trajectory of the projection specification position and the drivable region in a state where the projection specification position is moved to inside of the drivable region from outside. ### Claim 14 (depends on 2) The information processing apparatus according to claim 2, wherein the controller displays an effect image that changes in accordance with a shortest distance between the boundary and the projection specification position at a position on the boundary in a state where the projection specification position is moved to inside of the drivable region from outside. ### Claim 15 (depends on 2) The information processing apparatus according to claim 2, wherein the controller displays an effect image that extends in a direction of the projection specification position from a position on the boundary and changes in accordance with a distance to the projection specification position in a state where the projection specification position is moved to inside of the drivable region from outside. ### Claim 16 (depends on 1) The information processing apparatus according to claim 1, wherein the controller displays a bird's-eye view image of the projection environment space that indicates a trajectory of the projection specification position and the drivable region in a state where the projection specification position is located outside the drivable region for constant time. ### Claim 17 (depends on 1) The information processing apparatus according to claim 1, wherein the controller dynamically changes the drivable region in accordance with environment change of the projection environment space. ### Claim 18 (depends on 1) The information processing apparatus according to claim 1, wherein the controller determines, to the boundary, a

method comprising outputting, by a processor, feedback indicating an effect corresponding to a boundary of a drivable region of a drive-type projector in a projection environment space in accordance with a state of a projection specification position specified by a user for the drivable region, the state being determined based on the drivable region and the projection specification position. ### Claim 20 A recording medium recording a computer program for causing a computer to function as a controller that performs processing of outputting feedback indicating an effect corresponding to a
