    摘要: A probe for insertion into the body of a subject includes a sensor, a first microcircuit, which stores first calibration data with respect to the sensor, and a first connector at the proximal end of the probe. A probe adapter includes a second connector, which mates with the first connector, a signal processing circuit, which is processes the sensor signal, and a second microcircuit, which stores second calibration data with respect to the signal processing circuit. A microcontroller in the adapter receives the first and second calibration data and computes combined calibration data. The adapter includes a third connector, which mates with a fourth connector on a console. The console includes signal analysis circuitry, which analyzes the processed signal using the combined calibration data provided by the probe adapter.

    摘要: Point-of-gaze of a user looking at a display is estimated, taking into account rotation of the user's head or rotation of the display. An image of an eye of the user is captured. The image is processed to determine coordinates in the image of defined eye features, sufficient to determine the eye's optical axis. At least one angle is determined, the at least one angle proportional to an angle between (i) a line coincident with an edge of the display and (ii) an intersection of the sagittal plane of the user's head with a plane of the display. An intersection of the eye's line-of-sight with the plane of the display is estimated using the eye's optical axis, and using the at least one angle to account for rotation of the user's head or the display.
