The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

Transcutaneous analyte sensor

Architecture for implementing a perceptual user interface. The architecture comprises alternative modalities for controlling computer application programs and manipulating on-screen objects through hand gestures or a combination of hand gestures and verbal commands. The perceptual user interface system includes a tracking component that detects object characteristics of at least one of a plurality of objects within a scene, and tracks the respective object. Detection of object characteristics is based at least in part upon image comparison of a plurality of images relative to a course mapping of the images. A seeding component iteratively seeds the tracking component with object hypotheses based upon the presence of the object characteristics and the image comparison. A filtering component selectively removes the tracked object from the object hypotheses and/or at least one object hypothesis from the set of object hypotheses based upon predetermined removal criteria.

Architecture for controlling a computer using hand gestures

Systems and methods for applying time-dependent algorithmic compensation functions to data output from a continuous analyte sensor. Some embodiments determine a time since sensor implantation and/or whether a newly initialized sensor has been used previously.

Systems and methods for processing analyte sensor data

Systems and methods for integrating a continuous glucose sensor, including a receiver, a medicament delivery device, and optionally a single point glucose monitor are provided. Manual integrations provide for a physical association between the devices wherein a user (for example, patient or doctor) manually selects the amount, type, and/or time of delivery. Semi-automated integration of the devices includes integrations wherein an operable connection between the integrated components aids the user (for example, patient or doctor) in selecting, inputting, calculating, or validating the amount, type, or time of medicament delivery of glucose values, for example, by transmitting data to another component and thereby reducing the amount of user input required. Automated integration between the devices includes integrations wherein an operable connection between the integrated components provides for full control of the system without required user interaction.

Systems and methods for detecting noise episodes and processing analyte sensor data responsive thereto. In some embodiments, processing analyte sensor data includes filtering the sensor data to reduce or eliminate the effects of the noise episode on the signal.

An invention is provided for affording a real-time three-dimensional interactive environment using a three-dimensional camera. The invention includes obtaining two-dimensional data values for a plurality of pixels representing a physical scene, and obtaining a depth value for each pixel of the plurality of pixels using a depth sensing device. Each depth value indicates a distance from a physical object in the physical scene to the depth sensing device. At least one computer-generated virtual object is inserted into the scene, and an interaction between a physical object in the scene and the virtual object is detected based on coordinates of the virtual object and the obtained depth values.

System and method for providing a real-time three-dimensional interactive environment

Computer implemented method for interactively animating an avatar in response to real world input are provided. The avatar can be transmitted between a first user and a second user using a computer program that is executed on at least one computer in a computer network. Additionally, the first user and the second user each interact using a respective computing system that is at least partially executing the computer program. The method is initiated by identifying components of the avatar representing the first user that can be modified using real-time effects. The method continues by the computing system identifying controller input from either the first user or the second user. The identification of the controller input is used to determine which of the identified components of the avatar representing the first user will be modified. In response to the identified controller input the real-time effects are applied to the identified components of the avatar that represent the first user. The avatar of the first user augmented to reflect the application of the real-time effects. In another operation, the method displays the augmented avatar of the first user on a screen connected to the computing system of one or both of the first and second users.

Methods for interactive communications with real time effects and avatar environment interaction

A method and system for interactive interfacing with a computer gaming system is provided. The method includes providing an input device, where the input device is configured to convey mutlti-channel mixed input data that is to be interpreted by the computer gaming system. The method includes identifying an action to be performed by the computer gaming system, and the action is mapped to the mutlti-channel mixed input data provided by the input device. Then, a gearing is applied between the action to be performed by the computer gaming system and the mutlti-channel mixed input data received from the input device. The gearing scales an adjustment to impact the action to be performed by the computer gaming system. The gearing can be set dynamically by the game, by the user, or can be preset by software or user configured in accordance with a gearing algorithm.

Method and system for applying gearing effects to mutlti-channel mixed input

A hand-manipulated prop is picked-up via a single video camera, and the camera image is analyzed to isolate the part of the image pertaining to the object for mapping the position and orientation of the object into a three-dimensional space, wherein the three-dimensional description of the object is stored in memory and used for controlling action in a game program, such as rendering of a corresponding virtual object in a scene of a video display. Algorithms for deriving the three-dimensional descriptions for various props employ geometry processing, including area statistics, edge detection and/or color transition localization, to find the position and orientation of the prop from two-dimensional pixel data.

Method for mapping an object from a two-dimensional camera image to a three-dimensional space for controlling action in a game program

Methods and techniques for use in the operation of a game apparatus or other system for determining an activity level of a user in relation to the game apparatus or other system. A machine-readable medium having embodied thereon instructions for performing such methods and techniques is also included, as well as an example system for implementation.
