    摘要: Calibration of gaze tracking equipment is described, for example, in a desktop computing scenario. In various examples, an explicit calibration phase is carried out, optionally followed by an implicit calibration phase. In examples, the explicit calibration phase comprises requesting and receiving user manual input events associated with specified locations and measuring gaze associated with the manual input events. In examples, the implicit calibration phase is carried out without disturbing other activity of a user in the desktop computing environment, such as operating a graphical user interface. In various examples calibration data is stored in a plurality of buffers and used to control switching between explicit and implicit calibration phases.
