Abstract: Techniques for optimizing which LEDs in a HMD to use, the brightness of those LEDs, and camera exposure are divulged based on the particular function to be performed. For instance, one set of optimization parameters may be implemented for eye tracking purposes while a different set of optimization parameters may be implemented for eye-based authentication purposes.

Abstract: A floor reaction force to a foot of a legged mobile robot is detected with a suitable degree of accuracy, by use of a strain sensor having comparatively low sensitivity. The foot includes an upper frame connected to a movable leg, a lower frame which is disposed under the upper frame and contacts with a walking surface, a strain generating member which is connected to the upper frame and the lower frame at different positions from each other in top plan view and undergoes bending deformation according to a change in distance or inclination between the instep member and the sole member, and a plurality of strain sensors disposed at positions different from each other on the strain generating member.

Abstract: A robot eye and two different eye tracking systems may be used in tandem to determine the accuracy of eye tracking software that is used as part of one of the eye tracking systems. If inaccurate, the eye tracking software may then be adjusted in response. In various example embodiments, a camera may be used in one of the eye tracking systems to then track movement of the robot eye using the eye tracking software itself. Also in various example embodiments, the other eye tracking system may include components such magnetic sensors, optical sensors like CMOS sensors, and/or lasers for tracking the same movement of the robot eye.

Abstract: Techniques for simulating fast eye movement of a robot to mimic human eye saccade are divulged in cases of the robot eyes being moved by actuators that cannot move the eyes fast enough in real time to mimic saccade. Image capture timing is adjusted (i.e., slowed down) to track the speed of the actuators. Then, the resulting sequence of images is time-compressed back to video playback speed so that the video appears to show the robot eye undergoing saccade at human eye speeds.

Abstract: An operation device (3A or 3B) configured to operate an aiming position in response to an operation by a user includes a first switching operation unit (36) configured to receive an operation to switch an operation mode of the operation device, a detection unit (37) configured to detect movement of the operation device, an aiming operation unit (321 or 331) configured to operate the aiming position in response to an operation by the user, and a mode switching unit (411 or 415) configured to switch, depending on an operation on the first switching operation unit, the operation mode to one of a first mode in which the aiming position is determined on the basis of movement of the operation device detected by the detection unit and a second mode in which the aiming position is determined on the basis of an operation on the aiming operation unit.

Abstract: A rotation device includes a two-axis rotation mechanism including a first bevel gear, a second bevel gear disposed at a position where the second bevel gear coaxially faces the first bevel gear in an axial direction, a third bevel gear that meshes with the first bevel gear and the second bevel gear, a first motor for supplying rotational force to the first bevel gear, and a second motor for supplying rotational force to the second bevel gear; a one-axis rotation mechanism including a drive shaft and a third motor for supplying rotational force to the drive shaft; and an attachment member that attaches the two-axis rotation mechanism to the one-axis rotation mechanism such that a rotational axis of the drive shaft passes a point of intersection where a rotational axis of the first bevel gear and the second gear and that of the third bevel gear intersect with each other.
