Systems, methods and computer readable media comprising a virtual exercise board, which is represented by images on the screen of a pad device; wearable devices configured to attach to each shoe of a user and to collect and transmit touch data to the pad device; cameras for tracking movement and calibrating with the data collected by the wearable devices; and computer programs for collecting user data, processing user data, and generating outputs. In embodiments, features include augmented reality; ratings of performance; automated workouts/protocols; real-time progress bar; multi-location database capabilities; and reports.

A shoe has a sensor system operably connected to a communication port. Performance data is collected by the system and can be transferred for further use via the communication port. The shoe may contain an electronic module configured to gather data from the sensors. The module may also transmit the data to an external device for further processing. Users can use the collected data for a variety of different uses or applications.

A controller apparatus includes a capacitive or resistive touch pad having a touch sensitive surface sized sufficient for operation by two human feet. One or more markers are coupled to the touch pad. The markers are configured for use by a computer system for room mapping.

A method for graphical user interface (GUI) item selection using pressing state, pointing direction and/or tilt angle of a controller, includes detecting a change of the controller's pressing state from a first pre-determined pressing state to a second pre-determined pressing state; and when the controller's pressing state remains as the second pre-determined pressing state, evaluating an angle difference of a controller's pointing direction, and/or an angle difference of a controller's tilt angle; and determining an GUI item for selection using the evaluated angle difference of the controller's pointing direction, and/or the evaluated angle difference of the controller's tilt angle.

Described herein are systems, devices, and methods for aiding a user to scroll through or otherwise manipulate a stack of medical and tissue images. A system as described herein may comprise: a foot controller, configured to detect one or more of vertical and horizontal motion of a user’s foot to control image navigation, review, positioning, and viewing, functions; a computer; and a user interface.

A key input device applicable to a smart mat is provided, where the key input device includes a first layer in which a plurality of row contacts are formed, a second layer in which a plurality of column contacts are formed, an insulating layer disposed between the first and second layers to form an insulating region and a current carrying region, and a processor configured to detect that at least one of a plurality of key switches formed by the plurality of row contacts and the plurality of column contacts is pressed.

An image forming apparatus includes an information input device. The information input device includes a display section, an operation section, and a controller. The display section sequentially displays a plurality of options. The operation section receives a touch operation operated by a user with his/her foot. The controller performs control of selecting an option, displayed by the display section at a point in time of the touch operation on the operation section, from the plurality of options. For example, the options may be a number from 0 to 9, or a digit contained in a number containing a plurality of digits.

A method comprises operably coupling a surgical instrument to a first connector port of a plurality of connector ports of a flux supply unit. The method further comprises, in response to operably coupling the surgical instrument, altering an appearance of a first graphical user interface section of a plurality of graphical user interface sections presented on a display, each of the plurality of graphical user interface sections being aligned with a differing connector port of the plurality of connector ports.

A system for determining a gaze point of a user, the system comprising at least one sensor configured to determine at least one signal representative of a variation in a volume of the interior of a user's ear, and a processor configured to determine a direction of eye movement of the user based on the determined signal, and determine a gaze point of the user based on the direction of eye movement. Further, the disclosure relates to a corresponding method.

A virtual reality (VR) system includes a VR display and a VR movement apparatus that includes hand user interfaces (UIs) and foot UIs that can support the hands, feet, seat, and total weight of a user. The VR movement apparatus allow the user's hands and feet to move in 3-dimensional space that include vertical, lateral, and fore-aft direction movements. A computer running VR software coordinate and synchronizes the VR movement apparatus and the VR display to provide system users with simulated activities in a VR environment.
