The method, system, apparatus, and/or device may include a processing device configured to: associate a first cursor with a first form of a user input; associate a second cursor with a second form of the user input; determine the first form of the user input is associated with a type of the virtual object; display the virtual object with the first cursor to the viewer; detect the viewer input from the viewer of the display; determine whether the form of the viewer input detected by the sensor is the first form, the second form, or an unknown form; and in response to the form of the viewer input being the first form, execute an executable instruction associated with the user input.

Abstract: A method, system, apparatus, and/or device for interacting with a three dimensional interface. The method, system, apparatus, and/or device may include: generating a zone associated with a virtual object, wherein the zone includes a first space approximate to at least a portion of the object that is distinct from a second space occupied by the object; determine an uncertainty level of a sensor to identify an input in the zone; in response to the uncertainty level exceeding a first level, increasing a size of the zone, wherein the increased size of the zone increases a precision level of the sensor; and in response to the uncertainty level being below a second level, decreasing the size of the zone, wherein the decreased size of the zone decreases the precision level of the sensor.

Abstract: To prompt input and provide feedback on input to a user with an interface, inputs and graphical cursors associated with those inputs are defined. Each input may have several forms such as base, hover, engaged, completed, and error. User input is anticipated. The base form of the anticipated input cursor is displayed to prompt the user for the anticipated input. If user hover is detected that matches anticipated input, the hover form is displayed to confirm the match to the user. If user input is detected that matches anticipated input, the engaged form is displayed as confirmation. If user input is completed that matches anticipated input, the completed form is displayed as confirmation. If user hover or input does not match anticipated input, the error form is displayed to indicate mismatch. Not all cursors must have all forms, and some cursors may have multiples of some forms.

Abstract: Method and apparatus for interacting with a three dimensional interface. In the method, a three dimensional interface with at least one virtual object is generated. An interaction zone is defined and generated, enclosing some or all of the object. A stimulus of the interaction zone, e.g. approach/contact with a finger/stylus is defined, and a response to the stimulus is defined, e.g. changes to the object, system actions, feedback, etc. When the stimulus is sensed the response is executed. The apparatus includes a processor that generates a three dimensional interface with at least one virtual object, defines an interaction zone for the object, and defines a stimulus and a response. A display outputs the interface and object. A camera or other sensor detects stimulus of the interaction zone, whereupon the processor generates a response signal. The apparatus may be part of a head mounted display.

Abstract: A system, apparatus, device, or method to output different iterations of data entities. The method may include establishing a first data entity; establishing a first state for the first data entity. The method may include establishing a second state for the first data entity. The method may include storing the first data entity, the first state, and the second state at a storage device. The method may include retrieving a first iteration of the first data entity exhibiting at least a portion of the first state. The method may include retrieving a second iteration of the first data entity exhibiting at least a portion of the second state. The method may include outputting the first iteration and the second iteration at an output time.

Abstract: First and second images are captured at first and second focal lengths, the second focal length being longer than the first focal length. Element sets are defined with a first element of the first image and a corresponding second element of the second image. Element sets are identified as background if the second element thereof is more in-focus than or as in-focus as the first element. Background elements are subtracted from further analysis. Comparisons are based on relative focus, e.g. whether image elements are more or less in-focus. Measurement of absolute focus is not necessary, nor is measurement of absolute focus change; images need not be in-focus. More than two images, multiple element sets, and/or multiple categories and relative focus relationships also may be used.

Abstract: A wearable sensor vehicle with a bio-input sensor and a processor. When the vehicle is worn, the sensor is arranged so as to sense bio-input from the user. The sensor senses bio-input, the processor compares the bio-input to a standard, and if the standard is met the processor indicates a response. The user may be uniquely identified from the bio-input. One or more systems on or communicating with the vehicle may be controlled transparently, without requiring direct action by the user. Control actions may include security identification of the user, logging in to accounts or programs, setting preferences, etc. The sensor collects bio-input substantially without instruction or dedicated action from the user; the processor compares bio-input against the standard substantially without instruction or dedicated action from the user; and the processor generates and/or implements a response based on the bio-input substantially without instruction or dedicated action from the user.

Abstract: Apparatuses and methods of operating the same are described. An apparatus including a display, an input device, and a processing device coupled to the display and the input device. The processing device may send an output to the display. The output may include a graphical object associated with a first step of a user-implemented procedure. The processing device may receive an input from the input device. The input may indicate a progress on an execution of the first step by an operator. The processing device may determine whether the input indicates that the operator has completed the first step. The processing device may determine whether the first step is a final step in the user-implemented procedure. The processing device may identify a second step in the user-implemented procedure when the input indicates that the operator has completed the first step and the first step is not a final step.

An apparatus includes a processor, a data store, and an output. A data entity establisher, a state establisher, a storer, a data entity receiver, a state receiver, and an outputter are instantiated on the processor.

Abstract: To distinguish a region (e.g. hand) within a data set (e.g. digital image), data elements (e.g. pixels) representing a transition (e.g. hand outline) are identified. The direction toward the region is determined, for example using weighted direction matrices yielding a numerical maximum when aligned inward. A test element displaced one or more steps inward from the boundary element is tested against a standard for identifying the region. If the tested element meets the standard, that element is identified as part of the region. By examining data elements away from the transition, noise in the transition itself is avoided without altering the transition (e.g. by smoothing) while still only examining a linear data set (i.e. a contour or trace of the feature rather than a flooded interior thereof). The direction to the exterior of the region, an exterior contour, other features, and/or the transition also may be identified/followed.

Abstract: World data is established, including real-world position and/or real-world motion of an entity. Target data is established, including planned or ideal position and/or motion for the entity. Guide data is established, including information for guiding a person or other subject in bringing world data into match with target data. The guide data is outputted to the subject as virtual and/or augmented reality data. Evaluation data may be established, including a comparison of world data with target data. World data, target data, guide data, and/or evaluation data may be dynamically updated. Subjects may be instructed in positions and motions by using guide data to bring world data into match with target data, and by receiving evaluation data. Instruction includes physical therapy, sports, recreation, medical treatment, fabrication, diagnostics, repair of mechanical systems, etc.
