Abstract: An assessment of a subject's fitness is evaluated by having the subject go through whole body weight-bearing movement, with cuing provided to direct the subject's movements, and feedback provided to keep the subject at a desired exercise intensity. The subject's reaction to the exercise may be measured, for example with the subject's movements being tracked. An evaluation may be made, based at least in part on the measured reaction, for example by using data from the movement tracking, possibly in conjunction with data obtained by earlier testing, for example using a similar test protocol.

Abstract: A cognitive function evaluation method and system involves prompting a test subject (person) to engage in movement, such as whole-body movement, for example sports-specific movement, while tracking movement of the person. Data can be gathered from the tracking of the person's movement. This data can be compared with baseline data from an earlier test (or with data gathered from other subjects), to make a determination of cognitive function of the test subject, or to evaluate progress in rehabilitation and/or aid in making a determination whether a person is ready to resume specified activities, such as an athlete returning to a sport. Such a determination can be made under realistic activity-specific conditions (for example using increased metabolic rate and/or activity-specific movements that may test/challenge the test subjects cognition, vestibular, and/or visual performance/abilities), to allow a for determination of the person's cognitive function.

Abstract: Accurate simulation of sport to quantify and train performance constructs by employing sensing electronics for determining, in essentially real time, the player's three dimensional positional changes in three or more degrees of freedom (three dimensions); and computer controlled sport specific cuing that evokes or prompts sport specific responses from the player that are measured to provide meaningful indicia of performance. The sport specific cuing is characterized as a virtual opponent that is responsive to, and interactive with, the player in real time. The virtual opponent continually delivers and/or responds to stimuli to create realistic movement challenges for the player.

Abstract: A system and method for neurological testing involves prompting a subject or user to engage in body and head movements, measuring physical response, and then using the measured response to evaluate the neurological condition of the subject. The subject may wear a head-mounted display, for example, to aid in prompting the head and/or body movements. The subject may be prompted to engage in movements simulating a real-world task, such as a sports-specific activity. Results may be compared with those of a baseline test. The evaluation may be used to aid in determining if the user or subject can return to the task, for example to return to activity in a sport during which the user sustained a possible neurological injury.

Abstract: An interactive system tracks users in different physical spaces, both corresponding to a virtual space. The system resolves virtual collisions between the users in the virtual space. The system may resolve the virtual collision by examining the postures and power of the users. Different resolution criteria (“rules”) may be used for same-posture and different postures collisions.

Abstract: A method of imparting information includes interactively selectively displaying information to a person or user, based on the physical location of the person relative to a display screen upon which the information is displayed. A tracking system is operatively coupled to the display that selectively displays the information. The tracking system tracks the physical location of the person, and displays different information depending upon the physical location of the person. The display may include displays of virtual objects, such as cubes or other shapes. The view of the objects may be varied within the display as the user moves within physical space, varying the apparent position of the virtual objects as the user moves. The varying of the apparent position of the virtual objects may reveal information that was not visible to the user in other virtual positions (corresponding to other physical positions of the user).

Abstract: An exercise facility provides a physical space allowing unconstrained user movement in a low light level. The low light level improves the perceived user satisfaction with exercising, and may improve duration, frequency, and quality of the exercise. The room in which the physical space is located may have characteristics that reduce inhibitions against physical movement. These characteristics may include a dark floor, dark walls with a matte finish, and indirect lighting off of a light-colored ceiling. The environment may also aid in increasing focus of the user on the exercise task, removing distractions that might otherwise divert the attention of the user. The user-friendly environment may also aid the exercise system in following movement of the user within the physical space. For example, the environment surrounding the physical space may provide less interference than prior environments to infrared sensor systems.

Abstract: An interactive educational system includes a tracking system for determining changes in an overall physical location of a student, and a display for displaying cues for the student to engage in full-body motion and to engage in an interactive cognitive learning task. An educational method includes prompting a student to engage in an interactive cognitive learning task which involves full body motion, thereby enabling the student to reach the enhanced learning state which results from elevated metabolic rate, and synergistically engaging the student's kinesthetic learning facilities.
