In one example, a system for real-time three-dimensional (3D) calibration includes a processor detecting mark corners at two-dimensional (2D) coordinates in an image coordinate system of an image of a specified pattern. The processor determines 3D coordinates of the mark corners in a world coordinate system based on the pattern. The 3D coordinates correspond to the 2D coordinates. The processor determines baseline depth values corresponding to original depth values for proper points on a mark plane, based on the 2D coordinates and the 3D coordinates. The processor generates a fitting model based on the baseline depth values.

Real-time three-dimensional camera calibration

Methods, apparatuses, and articles of manufacture for a virtual touch screen keyboard. The method includes waiting for a movement of a mobile device. Upon movement of the device, the keyboard receives a measurement representing a position of the device from a sensor of the device. The keyboard determines whether an absolute value of the received measurement is greater than a pre-defined value. If the absolute value of the received measurement is greater than the pre-defined value, and the received measurement is negative, the keyboard displays a first portion of the virtual touch screen keyboard. If the absolute value of the received measurement is greater than the pre-defined value, and the received measurement is positive, the keyboard displays a second portion of the virtual touch screen keyboard. The first portion and the second portion of the virtual touch screen keyboard provide keys that are at least double in size to the keys provided on a conventional touch screen keyboard.
