Abstract: A method for interacting with an autostereoscopic display is disclosed. The method includes initiating displaying by the autostereoscopic display a left eye view and a right eye view that contain a virtual manipulated object, determining a real-world coordinate of the virtual manipulated object perceived by a user located at a predetermined viewing position of the auto stereoscopic display, receiving an interactive action of the user's manipulating body acquired by a motion tracker, where the interaction action includes a real-world coordinate of the manipulating body, determining whether an interaction condition is triggered based at least in part on the real-world coordinate of the virtual manipulated object and the real-world coordinate of the manipulating body, and refreshing the left eye view and the right eye view based on the interactive action of the manipulating body acquired by the motion tracker, in response to determining that the interaction condition is triggered.

Abstract: A method for correcting data sensed by a sensor includes: acquiring the data sensed by the sensor; establishing a surface equation based on an acquired data to performing surface fitting; and correcting the data sensed by the sensor with the surface equation. The method further includes: evaluating the acquired data sensed by the sensor to update fitting parameters of the surface equation so as to obtain an updated surface equation; and correcting the data sensed by the sensor with the updated surface equation. Parameter data sensed by the sensor can be corrected in real time, which reduces the influence of environmental factors on the parameter data sensed by the sensor and improves the accuracy of the data sensed by the sensor.
