Palm rejection and user experience design can be improved if the device knows whether the user is right-handed or left-handed. NVIDIA has extended the Android framework to allow the end user to specify their handedness in the DirectStylus Settings menu. This preference is accessible by applications, via querying the setting provider, system section, in the following ways:
Settings.System.getInt()function with the name parameter,
Settings.System.getInt()function to query
A return value of zero (0) indicates a preference for a right-handed configuration, while a return value of one (1) indicates a preference for a left-handed configuration.
It is recommended that application developers consider how their user interface may want to change depending on handedness, in order to offer the best end-user experience in both configurations. An example of what might change from right-hand mode to left-hand mode would be the relocation of a left-edge toolbar to the right-edge instead.
