An interactive display table has a display surface for displaying images and upon or adjacent to which various objects, including a user's hand(s) and finger(s) can be detected. A video camera within the interactive display table responds to infrared (IR) light reflected from the objects to detect any connected components. Connected component correspond to portions of the object(s) that are either in contact, or proximate the display surface. Using these connected components, the interactive display table senses and infers natural hand or finger positions, or movement of an object, to detect gestures. Specific gestures are used to execute applications, carryout functions in an application, create a virtual object, or do other interactions, each of which is associated with a different gesture. A gesture can be a static pose, or a more complex configuration, and / or movement made with one or both hands or other objects.

Input is provided to an application using a plurality of physical objects disposed adjacent to an interactive display surface. A primary location is determined where a primary physical object, e.g., a finger or thumb of the user, is positioned adjacent to the interactive display surface. An additional location is determined where an additional physical object is positioned adjacent to the interactive display surface. The attribute might be a size of an image or selected portion of the image that will be retained after cropping. A change in position of at least one of the objects is detected, and the attribute is adjusted based on the change in position of one or both objects. A range of selectable options of the application can also be display by touching the interactive display surface with one's fingers or other objects, and one of the options can be selected with another object.

Passive Physiological monitoring apparatus and method have a sensor for sensing physiological phenomenon. A converter converts sensed data into electrical signals and a computer receives and computes the signals, and outputs computed data for real-time interactive display. The sensor is a piezoelectric film of polyvinylidene fluoride. A band-pass filter filters out noise and isolates the signals to reflect data from the body. A pre-amplifier amplifies signals. Signals detected include mechanical, thermal and acoustic signatures reflecting cardiac output, cardiac function, internal bleeding, respiratory, pulse, apnea, and temperature. A pad may incorporate the PVDF film and may be fluid-filled. The film converts mechanical energy into analog voltage signals. Analog signals are fed through the band-pass filter and the amplifier. A converter converts the analog signals to digital signals. A Fourier transform routine is used to transform into the frequency domain. A microcomputer is used for recording, analyzing and displaying data for on-line assessment and for providing realtime response. A radio-frequency filter may be connected to a cable and the film for transferring signals from the film through the cable. The sensor may be an array provided in a MEDEVAC litter or other device for measuring acoustic and hydraulic signals from the body of a patient for field monitoring, hospital monitoring, transport monitoring, home, remote monitoring.

Systems and methods for processing gesture-based user interactions within an interactive display area are provided. The display of one or more virtual objects and user interactions with the one or more virtual objects may be further provided. Multiple interactive areas may be created by partitioning an area proximate a display into multiple volumetric spaces or zones. The zones may be associated with respective user interaction capabilities. A representation of a user on the display may change as the ability of the user to interact with one or more virtual object changes.

The present invention is directed to a method and system for use in a computing environment to present and provide access to information that a user cares about. A scheme is provided for presenting frequently used controls and information in tiles within a sidebar. Tiles are hosted individually or in groups, within a sidebar, for interaction by a user. Tiles can be added or removed from the sidebar automatically or by user request. The present invention is further directed to a method for providing a scaleable and useable preview of tiles within a sidebar. Further still, the present invention is directed to maintaining an overflow area of icons for tiles that would not fit within the sidebar. The sidebar has content that dynamically adjusts in response to the addition, expansion, squishing or removal of tiles. Even Further, a user can customize the sidebar of the present invention.

Techniques for using gaze actions to interact with interactive displays. A pointing device includes an eye movement tracker that tracks eye movements and an eye movement analyzer. The eye movement analyzer analyzes the eye movements for a sequence of gaze movements that indicate a gaze action which specifies an operation on the display. A gaze movement may have a location, a direction, a length, and a velocity. A processor receives an indication of the gaze action and performs the operation specified by the gaze action on the display. The interactive display may be digital or may involve real objects. Gaze actions may correspond to mouse events and may be used with standard graphical user interfaces.

An application state of a computer program is stored and associated with a physical object and can be subsequently retrieved when the physical object is detected adjacent to an interactive display surface. An identifying characteristic presented by the physical object, such as a reflective pattern applied to the object, is detected when the physical object is positioned on the interactive display surface. The user or the system can initiate a save of the application state. For example, the state of an electronic game using the interactive display surface can be saved. Attributes representative of the state are stored and associated with the identifying characteristic of the physical object. When the physical object is again placed on the interactive display surface, the physical object is detected based on its identifying characteristic, and the attributes representative of the state can be selectively retrieved and used to recreate the state of the application.

Systems, apparatuses and methods provide for detecting the proximate placement of an external NFC reader to a specific location on a display surface. The display surface can be intended for viewing indicia and enabling interaction with an NFC communication device embedded within the display. A circuit can control an NFC security system that can scan for unauthorized tags affixed to the surface of a display. The NFC security system may be activated by an NFC enabled mobile phone placed proximate to the indicated region for receiving an NFC coded message from the display. An NFC security scan can be performed prior to the mobile phone reading the message from the intended NFC tag in the display. Enabling interactive display modes can allow for making selections indicated on the display or detecting motion gestures across the face of the display.

A position of a three-dimensional (3D) object relative to a display surface of an interactive display system is detected based upon the intensity of infrared (IR) light reflected from the object and received by an IR video camera disposed under the display surface. As the object approaches the display surface, a “hover” connected component is defined by pixels in the image produced by the IR video camera that have an intensity greater than a predefined hover threshold and are immediately adjacent to another pixel also having an intensity greater than the hover threshold. When the object contacts the display surface, a “touch” connected component is defined by pixels in the image having an intensity greater than a touch threshold, which is greater than the hover threshold. Connected components determined for an object at different heights above the surface are associated with a common label if their bounding areas overlap.

A coded pattern applied to an object is identified when the object is placed on a display surface of an interactive display. The coded pattern is detected in an image of the display surface produced in response to reflected infrared (IR) light received from the coded pattern by an IR video camera disposed on an opposite side of the display surface from the object. The coded pattern can be either a circular, linear, matrix, variable bit length matrix, multi-level matrix, black / white (binary), or gray scale pattern. The coded pattern serves as an identifier of the object and includes a cue component and a code portion disposed in a predefined location relative to the cue component. A border region encompasses the cue component and the code portion and masks undesired noise that might interfere with decoding the code portion.
