Gesture based user interface for augmented reality

摘要

Technologies are generally described for systems and methods effective to provide a gesture keyboard that can be utilized with a virtual display. In an example, the method includes receiving sensory information associated with an object in proximity to, or in contact with, an input device including receiving at least one level of interaction differentiation detected from at least three levels of interaction differentiation, interpreting a command from the sensory information as a function of the at least one level of interaction differentiation, and outputting an action indication based on the command.

1. A method, comprising:
receiving sensory information associated with an object in proximity to, or in contact with, an input device including receiving at least three different levels of interaction differentiation comprising a proximity level of interaction differentiation, an electrical continuity level of interaction differentiation, and an actuation level of interaction differentiation; analyzing the at least one level of interaction differentiation, comprising:
determining the proximity level of interaction differentiation as a function of capacitance between the object and the input device, wherein the proximity level of interaction differentiation identifies a lateral position of the object with respect to the input device and a height of the object above a plane of the input device based on a trigonometric function of a first beat frequency in a first resonant circuit associated with a first character input component of the input device and a second beat frequency in a second resonant circuit associated with a second character input component of the input device,sensing the electrical continuity level of interaction differentiation based on detection of an electrical contact between a surface of at least one component of the input device and the object, anddetermining the actuation level of interaction differentiation based on movement of at least a portion of the input device by the object; determining a command from the sensory information based on a combination of the at least three levels of interaction differentiation, wherein a respective command for each combination of the at least three levels of interaction differentiation is distinguishable from other respective commands for other combinations of the at least three levels of interaction differentiation, comprising interpreting the command selected from different sets of commands based on whether the interaction differentiation is the proximity level, the electrical continuity level, or the actuation level; and outputting an action indication based on the command.
