An orientation and position tracking system and method in three-dimensional space and over a period of time utilizing multiple inertial and other sensors for determining motion parameters to measure orientation and position of a moveable object. The sensors, for example vibrational and angular velocity sensors, generate signals characterizing the motion of the moveable object. The information is received by a data acquisition system and processed by a microcontroller. The data is then transmitted to an external data reception system (locally based or a global network), preferably via wireless communication. The information can then be displayed and presented to the user through a variety of means including audio, visual, and tactile. According to various embodiments, the present invention provides for a motion tracking apparatus and method for implementation in motion systems including systems to teach motion to a group and for body motion capture and analysis systems.

Systems and methods for generating and playing a sequence of media objects based on a mood gradient are also disclosed. A mood gradient is a sequence of items, in which each item is media object having known characteristics or a representative set of characteristics of a media object, that is created or used by a user for a specific purpose. Given a mood gradient, one or more new media objects are selected for each item in the mood gradient based on the characteristics associated with that item. In this way, a sequence of new media objects is created but the sequence exhibits a similar variation in media object characteristics. The mood gradient may be presented to a user or created via a display illustrating a three-dimensional space in which each dimension corresponds to a different characteristic. The mood gradient may be represented as a path through the three-dimensional space and icons representing media objects are located within the three-dimensional space based on their characteristics.

A dimensioning system can include stored data indicative of coordinate locations of each reference element in a reference image containing a pseudorandom pattern of elements. Data indicative of the coordinates of elements appearing in an acquired image of a three-dimensional space including an object can be compared to the stored data indicative of coordinate locations of each reference element. After the elements in the acquired image corresponding to the reference elements in the reference image are identified, a spatial correlation between the acquired image and the reference image can be determined. Such a numerical comparison of coordinate data reduces the computing resource requirements of graphical comparison technologies.

A safety critical, time sensitive data system for projecting safety/mission critical data onto a display pair of Commercial Off The Shelf (COTS) light weight projection glasses or monocular creating a virtual 360° HUD (Heads Up Display) with 6 degrees of freedom movement. The system includes the display, the workstation, the application software, and inputs containing the safety/mission critical information (Current User Position, Total Collision Avoidance System—TCAS, Global Positioning System—GPS, Magnetic Resonance Imaging—MRI Images, CAT scan images, Weather data, Military troop data, real-time space type markings etc.). The workstation software processes the incoming safety/mission critical data and converts it into a three dimensional space for the user to view. Selecting any of the images may display available information about the selected item or may enhance the image. Predicted position vectors may be displayed as well as 3D terrain.

A 10-Foot media user interface is herein described. A computer user interface may be designed for primary use as a 10-Foot user interface, where a user controls the computer using a remote control device, instead of as a traditional 2-Foot user interface where the user controls the computer using keyboard and mouse from directly in from of the computer. The 10-Foot user interface uses 3D space and animations to more clearly indicate navigation and selection of items in the user interface to the controlling user. Use of three-dimensional space also increases the display screen real estate that is available for content items, and allows the media user interface to move unselected items out of primary view of the user. The user interface may animate movement in three-dimensions to allow the user to more easily conceptually follow navigation of the user interface.

A system and method for selectively monitoring movement of one or more objects having one or more object attributes in a three dimensional space. The method is achieved by following the steps of detecting a position of the one or more objects in the three dimensional space by collecting information from one or more static sensors; selecting each detected object for monitoring; uniquely identifying selected objects and assigning one or more variable sensors to monitor the uniquely identified object. The method further requires gathering information from the variable sensors for each identified object; detecting a direction of each identified object in the three dimensional space; and controlling the one or more variable sensors to continuously point to the assigned uniquely identified object.

A positioning apparatus for guiding resection of a patient tissue and guiding placement of a prosthetic implant component in a desired implant position with respect to the resected patient tissue and method of use are described. A locating block includes a mating surface contoured for mating contact with the patient tissue. A cutting plane indicator provides a physical indication of a desired cutting plane for the resection.

The placement position predetermination is at least partially based upon pre-operative imaging of the patient tissue.

New and Improved methods and apparatus for robotic path planning, selection, and visualization are described A path spline visually represents the current trajectory of the robot through a three dimensional space such as a room By altering a graphical representation of the trajectory—the path spline—an operator can visualize the path the robot will take, and is freed from real-time control of the robot Control of the robot is accomplished by periodically updating the path spline such that the newly updated spline represents the new desired path for the robot Also a sensor that may be located on the robot senses the presence of boundaries (obstacles) in the current environment and generates a path that circumnavigates the boundaries while still maintaining motion in the general direction selected by the operator The mathematical form of the path that circumnavigates the boundaries may be a spline
