Abstract: Communication with a user is more naturally and effectively realized. An information processing apparatus includes a first sensor (1101) that detects an object present in a first direction with respect to an autonomous mobile body; second sensors (1102, 1103) that detect the object present in the first direction with respect to the autonomous mobile body by a system different from a system of the first sensor; and an operation control unit (230) that controls an operation of the autonomous mobile body based on a detection result acquired by the first sensor and a detection result acquired by the second sensors.

Abstract: An information processing apparatus including a determination unit that acquires a first detection result and a second detection result. The first detection result indicates information regarding at least one of a position and an orientation of a projection unit. The projection unit causes display information to be displayed by projecting the display information onto a projection plane. The second detection result indicates a spatial positional relationship between the projection unit and the projection plane. The information processing apparatus further includes a control unit that controls an operation of the projection unit on a basis of the first detection result and the second detection result.

Abstract: A motor control apparatus according to the present invention comprises: a servo circuit for outputting a pulse width modulation signal; a low-pass filter for receiving the pulse width modulation signal outputted by the servo circuit as an input; and a driver circuit for receiving an output voltage of the low-pass filter as an input and thereby driving a brushless sensorless motor; wherein the servo circuit controls pulse width of the pulse width modulation signal so as to maintain rotational speed of the motor at a target rotational speed on the basis of an FG pulse signal outputted by the motor, the FG pulse signal representing the rotational speed of the motor by frequency. The motor control apparatus further includes a rotational speed changing means, the rotational speed changing means changing the rotational speed of the motor by gradually varying a voltage outputted by the driver circuit from a current voltage to a target voltage on input of a control start signal.
