TECHNOLOGIES FOR GRAPHICAL USER INTERFACE MANIPULATIONS USING MULTI-FINGER TOUCH INTERACTIONS

摘要

Technologies for manipulating a graphical user interface (GUI) of a display of a computing device include a touch screen of the display capable of receiving user input via physical contact of the user's fingers. The computing device determines whether the user has initiated multi-finger input gesture from which and a hand rotation angle may be determined based on touch points corresponding to the physical contact between the user's fingers and the touch screen. Based on the hand rotation angle, the computing device may take an action on the GUI, such as rotate an orientation of the GUI and/or display a virtual keyboard on the GUI relative to the hand rotation angle and/or the touch points. Other embodiments are described herein and claimed.
