Abstract: A method for controlling a device, in particular a prosthetic hand or a robotic arm, includes using an operator-mounted camera to detect at least one marker positioned on or in relation to the device. Starting from the detection of the at least one marker, a predefined movement of the operator together with the camera is detected and is used to trigger a corresponding action of the device. The predefined movement of the operator is detected in the form of a line of sight by means of camera tracking. A system for controlling a device, in particular a prosthetic hand or a robotic arm, includes a pair of AR glasses adapted to detect the at least one marker and to detect the predefined movement of the operator.

Abstract: Systems and methods for tracking an object in a workspace. A tracker is disposed relative to the object and includes a predefined geometry of markers having first and second marker arrangements, each including three markers in a collinear relationship. A camera with a view of the tracker generates an image comprising blobs, where a subset of the blobs is directly generated from the markers of the tracker, and a remainder is not. Blob groups each including three of the blobs and satisfying a collinear criterion are identified as candidates for having been directly generated by the marker arrangements. The subset of blobs is differentiated from the remainder of blobs based on the blob groups and the predefined marker geometry, and the differentiated subset of blobs is assigned to the markers of the tracker. The pose of the tracker in the workspace is then estimated based on the assigned blobs.

Abstract: A method, system and device for tracking an anatomical structure includes a section having a small cross section relative to the length, a first end of the section having a tip capable of being removably attached to the anatomical structure; and a second end of the section that has two position-indicating sensors located thereon. The position-indicating sensors are tracked and displayed by the system.

Abstract: A light source illuminates a field of interest that includes an illumination module capable of projecting illumination light to the field of interest and a light projector associated with the illumination module. The light source also includes an input device associated with the light projector; the input device capable of sending signals to the light projector such that the light projector simultaneously projects data light along with the illumination light to the field of interest.
