Publication number: 20130057467Abstract: The present invention comprises methods and apparatuses that can provide reliable communications between a computer and a haptic interface device. The methods and apparatuses can provide communication that is more secure against errors, failures, or tampering than previous approaches. Haptic devices allow a user to communicate with computer applications using the user's sense of touch, for example by applying and sensing forces with the haptic device. The host computer must be able to communicate with the haptic device in a robust and safe manner. The present invention includes a novel method of accomplishing such communication; a computer-readable medium that, when applied to a computer, causes the computer to communicate according to such a method; and a computer system having a host computer and a haptic device communicating according to such a method.Type: ApplicationFiled: October 26, 2012Publication date: March 7, 2013Applicant: Novint Technologies, Inc.Inventor: Novint Technologies, Inc.

Patent number: 7379048Abstract: The present invention provides a method of human-computer interfacing that provides efficient implementation of intuitive controls in a three-dimensional space. The method comprises providing a three-dimensional space, characterized by x and y dimensions, together defining a plane approximately orthogonal to the user's direction of view into the space. A z dimension, approximately parallel to the direction of view, further characterizes the three-dimensional space. Objects in the space can be defined by x, y, and z coordinate sets. A control is provided having x and y coordinate sets as any other object. The z coordinate set of the control, however, spans a range of values, giving the control an increased depth. The control's range of z can be infinite, making the control accessible at all depths, or can be a finite range, making the control accessible only from that range of depths. Movement of a cursor into the region corresponding to the control initiates interaction with the user according to the control.Type: GrantFiled: April 22, 2004Date of Patent: May 27, 2008Assignee: Novint Technologies, Inc.Inventor: Thomas G.

Patent number: 7225115Abstract: The present invention provides a method of generating haptic interface experiences that is capable of generating haptic companions to existing two-dimensional images. The method exploits the dominance of visual over haptic in humans: human tactile, proprioceptive, and kinesthetic senses do not supply as much fine detail as human vision, and consequently haptic representations do not have to be as detailed as the corresponding visual images to be believable to a human user. An existing two-dimensional image can be used as the visual component of a human-computer interface. A three-dimensional haptic model that is topologically similar to the image can be selected, where topological similarity means that the haptic model provides an acceptable approximation to important characteristics of the haptic experience desired to accompany the two-dimensional image.Type: GrantFiled: October 4, 2001Date of Patent: May 29, 2007Assignee: Novint Technologies, Inc.Inventor: Jake S.

Patent number: 6954899Abstract: The present invention provides a method of human-computer interfacing that provides haptic feedback to control interface interactions such as scrolling or zooming within an application. Haptic feedback in the present method allows the user more intuitive control of the interface interactions, and allows the user's visual focus to remain on the application. The method comprises providing a control domain within which the user can control interactions. For example, a haptic boundary can be provided corresponding to scrollable or scalable portions of the application domain. The user can position a cursor near such a boundary, feeling its presence haptically (reducing the requirement for visual attention for control of scrolling of the display). The user can then apply force relative to the boundary, causing the interface to scroll the domain. The rate of scrolling can be related to the magnitude of applied force, providing the user with additional intuitive, non-visual control of scrolling.Type: GrantFiled: February 16, 2001Date of Patent: October 11, 2005Assignee: Novint Technologies, Inc.Inventor: Thomas G.

Patent number: 6833826Abstract: The present invention provides a method of human-computer interfacing. Force feedback allows intuitive navigation and control near a boundary between regions in a computer-represented space. For example, the method allows a user to interact with a virtual craft, then push through the windshield of the craft to interact with the virtual world surrounding the craft. As another example, the method allows a user to feel transitions between different control domains of a computer representation of a space. The method can provide for force feedback that increases as a user's locus of interaction moves near a boundary, then perceptibly changes (e.g., abruptly drops or changes direction) when the boundary is traversed.Type: GrantFiled: August 14, 2000Date of Patent: December 21, 2004Assignee: Novint Technologies, Inc.Inventor: Thomas G.

Patent number: 6727924Abstract: A method of human-computer interfacing provides efficient intuitive controls in a three-dimensional space. The method provides a three-dimensional space, characterized by a z dimension approximately parallel to the user's direction of view, and x and y dimensions approximately orthogonal thereto. A control has x and y coordinate sets, and a z coordinate set that spans a range of values. The range can be infinite, making the control accessible at all depths, or can be a finite range, making the control accessible from that range of depths. Movement of a cursor into the control's region initiates user interaction according to the control. The control depth reduces the precision of depth perception required to find the control. Once the user is in the control region, the effective depth for interaction can be relative to the depth when the user entered, providing control interaction independent of entering depth.Type: GrantFiled: October 17, 2000Date of Patent: April 27, 2004Assignee: Novint Technologies, Inc.Inventor: Thomas G.

Patent number: 6724400Abstract: The present invention provides a human-computer interface. The interface includes provision of an application domain, for example corresponding to a three-dimensional application. The user is allowed to navigate and interact with the application domain. The interface also includes a personal domain, offering the user controls and interaction distinct from the application domain. The separation into two domains allows the most suitable interface methods in each: for example, three-dimensional navigation in the application domain, and two- or three-dimensional controls in the personal domain. Transitions between the application domain and the personal domain are under control of the user, and the transition method is substantially independent of the navigation in the application domain. For example, the user can fly through a three-dimensional application domain, and always move to the personal domain by moving a cursor near one extreme of the display.Type: GrantFiled: August 29, 2000Date of Patent: April 20, 2004Assignee: Novint Technologies, Inc.Inventor: Thomas G.
