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: 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.
