Patent number: 10900808Abstract: A system determines the transmission strength of the magnetic field signal. The magnetic field signal is transmitted from a first magnetic-sensor device to a second magnetic-sensor device. The system then determines a first projected distance between the first magnetic-sensor device and the second magnetic-sensor device. Based at least in part on the first projected distance, the system calculates an adjusted transmission strength for the magnetic field signal. The system then causes the first magnetic-sensor device to transmit an adjusted magnetic field signal. The adjusted magnetic field signal comprises the adjusted transmission strength. The system receives, from the second magnetic-field device, the adjusted magnetic field signal. Based at least in part upon the received adjusted magnetic field signal, the system, computes a first pose of the first magnetic-sensor device in relation to the second magnetic-sensor device.Type: GrantFiled: September 16, 2019Date of Patent: January 26, 2021Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Quentin Simon Charles Miller, Scott Francis Fullam, Lev Cherkashin, Steven James Velat

Patent number: 10746815Abstract: A mixed-reality system causes a magnetic transmission device to transmit a magnetic field signal. The mixed-reality system also causes a magnetic-field sensing device to determine a measurement of the magnetic field signal. The mixed-reality system then identifies, using one or more input devices, that a magnetically-interfering object is located within a same environment as both the magnetic transmission device and the magnetic-field sensing device. The mixed-reality system also determines one or more characteristics of magnetic field interference that the magnetically-interfering object is imparting on the magnetic transmission device or the magnetic-field sensing device. The mixed-reality system then computes an adjustment to a pose-estimation model based upon the one or more characteristics of magnetic field interference. The pose-estimation model is used to calculate a pose of at least one of the magnetic transmission device or the magnetic-field sensing device.Type: GrantFiled: April 24, 2017Date of Patent: August 18, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Quentin Simon Charles Miller, Scott Francis Fullam, Lev Cherkashin, Steven James Velat, Simon Skaria
