A controller for a motion assisting apparatus for a wearer includes circuitry. The circuitry is configured to set switching points in a change in a turning angle of a drive mechanism driven by a drive motor and attached to an ankle joint of the wearer to assist a turning motion of the ankle joint, a ratio of the change in the turning angle being equal to zero at the switching points. The circuitry is configured to set a motion pattern such that the turning angle monotonically increases or monotonically decreases between the switching points. The circuitry is configured to control the drive motor to change the turning angle according to the motion pattern.

The present technology relates to an information processing device, an information processing method, and a program capable of facilitating fixed-point observation on skin condition. The information processing device according to an aspect of the present technology acquires an image that shows a predetermined feature point of a user who is a measurer of skin condition, and a measurement portion of skin condition, and analyzes the image, and then recognizes a position of the feature point. Furthermore, information indicating the measurement portion is displayed at a predetermined position on the image while setting, as a reference, the recognized position of the feature point. The present technology is applicable to information processing devices such as a tablet terminal, a smartphone, and a personal computer.

A motion sensor is attached to a patient's limb distal to a joint on which surgery has occurred and another motion sensor is attached to the limb proximate to the joint. In the preferred embodiment, the motion sensors are accelerometers and gyroscopes that are capable of generating data that corresponds to flexion of the joint. Temperature sensors are attached to the patient at the surgical site at the joint and at a site separated from the surgical site so that the temperature difference between the sensors may be monitored. Data from the sensors is used to monitor the patient's post-surgical condition and rehabilitation and to provide feedback to the patient.
