Portrait-Landscape Rotation Heuristics for a Portable Multifunction Device

The concept of rotation is described by Patently Apple (2011) as a computer-implemented method, comprising of a multifunctional device such as an ipad or iphone with a touch screen and one or more accelerometers. The process occurs based on an analysis of data received from one or more accelerometers that determines the rotation.

The process of iphone orientation and change as described by Apple (2011) ‘supports the usability as it allows users to view applications and complete tasks in a more user friendly way’
