Abstract: A method of performing localization of a handheld device with respect to a wearable device includes capturing, by a first imaging device mounted to the handheld device, a fiducial image containing a number of fiducials affixed to the wearable device and capturing, by a second imaging device mounted to the handheld device, a world image containing one or more features surrounding the handheld device. The method also includes obtaining, by a sensor mounted to the handheld device, handheld data indicative of movement of the handheld device, determining the number of fiducials contained in the fiducial image, and updating a position and an orientation of the handheld device using at least one of the fiducial image or the world image and the handheld data.

Abstract: Techniques are disclosed for performing localization of a handheld device with respect to a wearable device. At least one sensor mounted to the handheld device, such as an inertial measurement unit (IMU), may obtain handheld data indicative of movement of the handheld device with respect to the world. An imaging device mounted to either the handheld device or the wearable device may capture a fiducial image containing a number of fiducials affixed to the other device. The number of fiducials contained in the image are determined. Based on the number of fiducials, at least one of a position and an orientation of the handheld device with respect to the wearable device are updated based on the image and the handheld data in accordance with a first operating state, a second operating state, or a third operating state.
