Patent number: 9063617Abstract: An interactive display system that may be implemented to provide an electronic whiteboard that enables users to input information to the system by engaging a display with one or more objects. The system may present an image via the display that reflects the inputs received from the user. For example, the display may be dynamically updated to mimic inputs made to a whiteboard by the user via one or more pens and/or an eraser. The interactive display system may implement an underlayer embedded within the display to guide electromagnetic radiation that emanates from an object engaged with the display to one or more detectors by total internal reflection. Due at least in part to the efficiency of the underlayer in guiding the electromagnetic radiation to the detectors, the interactive display system may enhance the speed and/or accuracy of the interpretation of the inputs made by the user.Type: GrantFiled: October 16, 2006Date of Patent: June 23, 2015Assignee: FlatFrog Laboratories ABInventors: Jonas Ove Philip Eliasson, Niels Agersnap Larsen, Jens Bastue, Jens Wagenblast Stubbe Østergaard

Patent number: 8094136Abstract: An optical touchpad that may be able to provide accurate, reliable information about the position of an object in three-dimensions. The optical touchpad may enable a determination as to whether the object is engaged with the touchpad or hovering just above the touchpad. When the object is in contact with the optical touchpad, the optical touchpad may enable a determination of the force applied by the object to the optical touchpad. The optical touchpad may enable a determination of an object type of the object. These and other determinations of information related to the object may enhance the control provided by the touchpad system to the user as an electronic interface. The operation of the optical touchpad may further enable an enhanced frame rate, reduced optical noise in the optical signal(s) guided to the one or more sensors, augment the ruggedness of the optical touchpad, an enhanced form factor (e.g., thinner), and/or provide other advantages.Type: GrantFiled: July 6, 2006Date of Patent: January 10, 2012Assignee: FlatFrog Laboratories ABInventors: Jonas Ove Philip Eliasson, Niels Agersnap Larsen, Jens Bastue, Jens Wagenblast Stubbe Ostergaard

Patent number: 8031186Abstract: An optical touchpad system is disclosed that may be easily integrated into a variety of applications. One feature of the optical touchpad system that may contribute to this versatility may be the ability of the optical touchpad system to function in the same manner independent from a topology and/or opacity of an interface surface of the optical touchpad system. This may enable the interface surface to be composed of any of a variety of materials. This may further enable the interface surface to include various topologies adapted for the application in which the optical touchpad system may be employed.Type: GrantFiled: July 6, 2006Date of Patent: October 4, 2011Assignee: FlatFrog Laboratories ABInventor: Jens Wagenblast Stubbe Ostergaard

Patent number: 7995039Abstract: Radiation guided by Total Internal Reflection inside a solid element from a point of engagement of a reflecting/emitting/scattering object and toward a detector reaches an area of the solid element on which the surface has areas preventing reflection of the radiation back into the element.

Patent number: 7442914Abstract: A method and a system for determining the position of a radiation emitter, which radiation emitter may be an actively radiation emitting stylus, pen, pointer, or the like or may be a passive, radiation scattering/reflecting/diffusing element, such as a pen, pointer, or a finger of an operator. The radiation from the emitter is reflected from that position toward the detector by a reflecting element providing multiple intensity spots on the detector providing sufficient information for determining the position. From the output of the detector, the position of the radiation emitter is determined.Type: GrantFiled: September 9, 2004Date of Patent: October 28, 2008Assignee: Flatfrog Laboratories ABInventors: Jonas Ove Philip Eliasson, Jens Wagenblast Stubbe Østergaard

Patent number: 7435940Abstract: A method and a system, such as a touch pad, for determining the position of a radiation emitter, which radiation emitter may be an actively radiation emitting stylus, pen, pointer, or the like or may be a passive, radiation scattering/reflecting/diffusing element, such as a pen, pointer, or a finger of an operator. The radiation is modulated by a bar code element and provided onto an at least one-dimensional detector. From the output of the detector, the position of the radiation emitter is determined. This system may be used as a standard touch pad or for determining the position of emitters external thereto, such as a marker used on a wall or black/white board or may be used with “internal” positions such as a touch pad.Type: GrantFiled: March 12, 2004Date of Patent: October 14, 2008Assignee: Flatfrog Laboratories ABInventors: Jonas Ove Philip Eliasson, Jen Wagenblast Stubbe Østergaard

Publication number: 20080189046Abstract: A tool configured to emit electromagnetic radiation therefrom such that one or more aspects of the emission of the electromagnetic radiation may be varied as a function of time. By varying the emission of the electromagnetic radiation as a function of time, the tool may enable information related to its position and/or motion to be determined with an enhanced specificity based on detection of the emitted electromagnetic radiation. For example, the varying emission of the electromagnetic radiation may enable a three dimensional position of the tool to be determined, may enable the position of the tool to be determined in three rotational degrees of freedom, and/or may enable time derivatives of these (and other) position information to be determined to quantify motion of the tool. In some implementations, the emission of the electromagnetic radiation may be varied such that position and/or motion information related to a plurality of tools may be determined simultaneously (or substantially simultaneously).Type: ApplicationFiled: February 2, 2007Publication date: August 7, 2008Applicant: O-PEN A/SInventors: Jonas Ove Philip Eliasson, Niels Agersnap Larsen, Jens Bastue, Jens Wagenblast Stubbe Ostergaard
