Patent attributes
One embodiment is directed to a system for human-computer interface, comprising an input device configured to provide two or more dimensions of operational input to a processor based at least in part upon a rubbing contact pattern between two or more digits of the same human hand that is interpreted by the input device. The input device may be configured to provide two orthogonal dimensions of operational input pertinent to a three-dimensional virtual environment presented, at least in part, by the processor. The input device may be configured to detect the rubbing between a specific digit in a pen-like function against one or more other digits. The input device further may be configured to detect the rubbing between the specific digit in a pen-like function and one or more other digits in a receiving panel function.
