Patent number: 8654104Abstract: Placement by one or more input mechanisms of a touch point of a mufti-touch display device that is displaying a three-dimensional object is detected. A two-dimensional location of the touch point on the multi-touch display device is determined, and the touch point is matched with a three-dimensional contact point on a surface of the three-dimensional object that is projected for display onto the image plane of the camera at the two-dimensional location of the touch point. A change in applied pressure at the touch point is detected, and a target depth value for the contact point is determined based on the changed in applied pressure. A solver is used to calculate a three-dimensional transformation of the three-dimensional object using an algorithm that reduces a difference between a depth value of the contact point after object transformation and the target depth value.Type: GrantFiled: July 22, 2013Date of Patent: February 18, 2014Assignee: Perceptive Pixel Inc.Inventors: Jason L.

Patent number: 8633924Abstract: A three-dimensional data set is accessed. A two-dimensional plane is defined that intersects a space defined by the three-dimensional data set. The two-dimensional plane defines a two-dimensional data set within the three-dimensional data set and divides the three-dimensional data set into first and second subsets. A three-dimensional view based on the three-dimensional data set is rendered on such that at least a portion of the first subset of the three-dimensional data set is removed and at least a portion of the two-dimensional data set is displayed. A two-dimensional view of a first subset of the two-dimensional data set also is rendered. Controls are provided that enable visual navigation through the three-dimensional data set by engaging points on the multi-touch display device that correspond to either the three-dimensional view based on the three-dimensional data set and/or the two-dimensional view of the first subset of the two-dimensional data set.Type: GrantFiled: March 23, 2012Date of Patent: January 21, 2014Assignee: Perceptive Pixel Inc.Inventor: Philip L.

Patent number: 8564565Abstract: Techniques are described for providing a cleaned signal in a capacitive touch sensor. A phase of periodic noise on an input of the capacitive touch sensor is determined, and a periodic excitation signal having a phase that is locked to the determined phase of the periodic noise is generated. The periodic excitation signal is applied to an excited conductor in a first array of the touch sensor. While the excitation signal is applied, a response signal on a responding conductor in a second array of the touch sensor is detected, and, based on the detected response signal, a value indicative of a measured capacitance between the excited conductor and the responding conductor is generated. A threshold value is accessed, and a determination is made whether the response signal corresponds to a touch based on a difference between the value and the threshold value.Type: GrantFiled: November 17, 2011Date of Patent: October 22, 2013Assignee: Perceptive Pixel Inc.Inventor: Jonathan Westhues

Patent number: 8473862Abstract: A process for enabling objects displayed on a multi-input display device to be grouped together is disclosed that includes defining a target element that enables objects displayed on a multi-input display device to be grouped together through interaction with the target element. Engagement of an input mechanism with one of the target element and a particular one of the objects displayed on the multi-input display device is detected. Movement of the input mechanism is monitored while the input mechanism remains engaged with whichever one of the target element and the particular displayed object that the input mechanism engaged. A determination is made that at least a portion of a particular displayed object is overlapping at least a portion of a target element on the multi-input display device upon detecting disengagement of the input mechanism.Type: GrantFiled: May 21, 2010Date of Patent: June 25, 2013Assignee: Perceptive Pixel Inc.Inventor: Philip L Davidson

Patent number: 8462148Abstract: A three-dimensional object is initially transformed using an initial three-dimensional transformation in response to the detected movement of at least one touch point of a set of touch points placed on a multi-touch display device, each touch point in the set being matched with a contact point on the surface of the object. If the initially transformed object does not correspond to a rotational exhaustion situation, displaying the initially transformed object on the multi-touch display device. If the initially transformed object corresponds to a rotational exhaustion situation, calculating a corrected three-dimensional transformation of the object by using an algorithm that fixes at least one degree of freedom of object orientation to a value corresponding to an orientation of the object prior to the detected movement of the at least one touch point. Transforming the object using the corrected three-dimensional transformation and displaying the transformed object.Type: GrantFiled: April 1, 2010Date of Patent: June 11, 2013Assignee: Perceptive Pixel Inc.Inventors: Jason L.

Patent number: 8456466Abstract: A three-dimensional transformation of a three-dimensional object is calculated by a solver using an algorithm that reduces deviation between projected two-dimensional locations of three-dimensional contact points on a surface of the object after object transformation and two dimensional locations of touch points placed on a multi-touch display device. The algorithm is biased to generate a three-dimensional transformation that preferentially rotates the object in one direction over an opposite direction when all three-dimensional contact points are located at substantially the same depth along a Z-axis away from an image plane of the multi-touch display device and when transformation is then triggered by touch points moving such that a Euclidean distance between at least two of the touch points decreases.Type: GrantFiled: April 1, 2010Date of Patent: June 4, 2013Assignee: Perceptive Pixel Inc.Inventors: Jason L.
