Abstract: Thumb+pen inputs are described herein, to improve the functionality of touch enabled devices for accepting bimanual input in situations where the device is gripped or supported by one of the user's hands, leaving only one hand free. The thumb of an engaging hand is identified and controls are placed within its range of motion to enhance the functionality provided by the free hand. The actions of the thumb can be used to determine how pen actions made using the other hand are interpreted. Alternatively, the pen can indicate an object through pointing, while the thumb indirectly manipulates one or more of its parameters through touch controls. Marking menus, spring-loaded modes, indirect input, and conventional multi-touch interfaces are applied with respect to the bimanual input mode in which one hand is positioned to hold or support the device, and the other hand is free to improve device operability and accessibility.

Abstract: A method for processing virtual pointer movement. The method and related components that, when active in an application or virtual environment as a whole, will aid a user in tasks that would require more effort and dexterity with currently implemented pointers. The method uses three operations (separated into two components, Smooth Pointer and Aim Assist Area) that result in a systematic asynchronous movement of a controller and its interface counterpart. Smooth Pointer, responsible for the pointer's stability, is a group of features that manage the process of smoothing the controller's rotation and final virtual pointer position by using a continuous interpolation process. Furthermore, Aim Assist Area is the component (based on two methods: Magnetism and Friction) that describes how the pointer will suffer interferences from the environment to help users have more stability while aiming at elements available in the interface.
