A force measurement system is disclosed herein. In one embodiment, the system includes a force measurement assembly configured to receive a subject; a data processing device operatively coupled to the force measurement assembly, the data processing device configured to determine a center of pressure for the subject using output forces and/or moments from the force measurement assembly; and a mobile device configured to determine one or more parameters indicative of the body sway for the subject. In this embodiment, a fall risk of the subject is assessed based upon a combination of the center of pressure and the one or more parameters indicative of the body sway determined for the subject.

A user-input device includes a user-actuatable trigger configured to pivot about a trigger axis, a posture sensor configured to determine a posture of the user-actuatable trigger about the trigger axis, a force sensor configured to determine an actuation force applied to the user-actuatable trigger, and a force-feedback motor operatively coupled to the user-actuatable trigger. The force-feedback motor is configured to activate based on a force-feedback signal and adjust a user-perceived state of the user-actuatable trigger.

The present invention provides an interactive system comprising at least one interactive visual display surface, at least one interactive computer being interconnected to said surface comprising an operating system and methods of operating the same.

A method for controlling a host device for at least one moving device including the following steps: determining a current position of the at least one moving device relative to an interaction surface of the host station using at least one electrical signal induced by at least one inductive magnetic field in at least one electric circuit of the host device associated with the interaction surface; recording the current position in a position history; using the history to compare a change of the position of the at least one device with at least one reference change diagram, the reference change diagram being associated with at least one reference movement; and activating a command of the host station on the basis of the reference movement, if the change corresponds to the reference movement.

A display apparatus with detection function of the present disclosure includes a first illumination unit that outputs first illumination light, a light valve that generates image light by modulating the first illumination light on the basis of image data, a projection optical system that projects the image light onto a projection plane, a second illumination unit that outputs second illumination light used for position detection of a position detection object on the projection plane, a third illumination unit that outputs third illumination light used for image recognition of an image recognition object on the projection plane, an imaging unit where the second illumination light and the third illumination light enter through the projection optical system, and includes an imaging device disposed at an optically conjugate position with the light valve, and an image processing unit that performs position detection of the position detection object and image recognition of the image recognition object on the basis of a result of imaging by the imaging unit.

Described herein are, among other things, handheld controllers that include one or more touchpads (i.e., touch-sensitive controls) configured to detachably couple to one or more overlays that effectively transform the respective touchpad into a different control. For instance, one example handheld controller may include a circular trackpad that is configured to detect a position of a finger on a top surface of the trackpad. This position may be used to control a cursor or avatar, for scrolling, or for any other type of command. In general, most or all of the top surface may be usable by a user for providing input to the controller and/or a remote system coupled to the controller. As described herein, however, one or more different overlays may detachably couple to a housing of the controller and/or the trackpad itself to effectively change the use of the trackpad.

A force measurement system is disclosed herein. In one embodiment, the system includes a force measurement assembly configured to receive a subject; a data processing device operatively coupled to the force measurement assembly, the data processing device configured to determine a center of pressure for the subject using output forces and/or moments from the force measurement assembly; and a mobile device configured to determine one or more parameters indicative of the body sway for the subject. In this embodiment, a fall risk of the subject is assessed based upon a combination of the center of pressure and the one or more parameters indicative of the body sway determined for the subject.

The application provides for a system and method of playing an educational balancing game. An electronic game spinner is used to select a category to be tested, as well as a specific question within this category. Once the specific question has been selected, potential answers are shown on an electronic game board whereby a user must then use their body to select a circle containing an answer. The game board may also be constructed out of plastic, where the answers are fixed, however, the electronic game spinner scans a code on the game board so that appropriate questions are used with the printed answer selections.

A game controller includes a housing; a top panel disposed on an opening portion of the housing and having a manipulation input surface; a position detector configured to detect a position of a manipulation input performed on the manipulation input surface; a vibrating element configured to generate a vibration in the manipulation input surface of the top panel; and a drive controlling part configured to drive the vibrating element by using a driving signal causing the vibrating element to generate a natural vibration in an ultrasound-frequency-band in the manipulation input surface.

A method that incorporates teachings of the subject disclosure may include, for example, receiving, by a device comprising a processor, a first signal from a motion-sensitive component of the device; receiving, by the device, a second signal from a touch-sensitive interface of the device, detecting, by the device, from a combined signal comprising the first signal and the second signal, a selection of a portion of the device; and causing, by the device, a sensory feedback generator to provide a feedback signal in accordance with the combined signal. The feedback signal may comprise an audible sound, a visual effect, a tactile effect, or any combination thereof. Additional embodiments are disclosed.
