| 20130093756 | Volumetric Data Exploration Using Multi-Point Input Controls - 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. | 04-18-2013 |

| 20130069860 | Organizational Tools on a Multi-touch Display Device - 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. As a consequence of disengagement and the overlap, processes are invoked that establish a relationship between the particular displayed object and a position on the target element and that causes transformations applied to the target element also to be applied to the particular displayed object while maintaining the relationship between the particular displayed object and the position on the target element. | 03-21-2013 |
| 20120268427 | Optical Filtered Sensor-In-Pixel Technology for Touch Sensing - Optical filtered sensor-in-pixel technology for touch sensing, in which a waveguide receives infrared light emitted by a light source and causes at least some of the received infrared light to undergo total internal reflection within the waveguide. A frustrating layer is disposed relative to the waveguide so as to contact the waveguide when a touch input is provided. The frustrating layer causes frustration of the total internal reflection of the received infrared light within the waveguide at a contact point between the frustrating layer and the waveguide. A sensor-in-pixel display displays an image that is perceivable through the waveguide and the frustrating layer and includes photosensors. The photosensors have a photosensor corresponding to each pixel of the image and sense at least some of the infrared light that escapes from the waveguide at the contact point. | 10-25-2012 |
| 20120227012 | Graphical User Interface for Large-Scale, Multi-User, Multi-Touch Systems - A method implemented on the graphical user interface device to invoke an independent, user-localized menu in an application environment, by making a predetermined gesture with a pointing device on an arbitrary part of a display screen or surface, especially when applied in a multi-touch, multi-user environment, and in environments where multiple concurrent pointing devices are present. As an example, the user may trace out a closed loop of a specific size that invokes a default system menu at any location on the surface, even when a second user may be operating a different portion of the system elsewhere on the same surface. As an additional aspect of the invention, the method allows the user to smoothly transition between the menu-invocation and menu control. | 09-06-2012 |
| 20120223911 | Reduction of Noise in Touch Sensors - 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. | 09-06-2012 |

| 20120182266 | MULTI-TOUCH SENSING THROUGH FRUSTRATED TOTAL INTERNAL REFLECTION - High-resolution, scalable multi-touch sensing display systems and processes based on frustrated total internal reflection employ an optical waveguide that receives light, such as infrared light, that undergoes total internal reflection and an imaging sensor that detects light that escapes the optical waveguide caused by frustration of the total internal reflection due to contact by a user. The optical waveguide when fitted with a compliant surface overlay provides superior sensing performance, as well as other benefits and features. The systems and processes described provide true multi-touch (multi-input) and high-spatial and temporal resolution capability due to the continuous imaging of the frustrated total internal reflection that escapes the entire optical waveguide. Among other features and benefits, the systems and processes are scalable to large installations. | 07-19-2012 |
| 20120146934 | Event Registration and Dispatch System and Method for Multi-Point Controls - Dynamic registration of event handlers in a computer application or operating system recognizes multiple synchronous input streams by identifying each new stroke in a frame representing a single moment in time and mapping in a registration process each identified new stroke to a listening process that is associated with the user interface element to which the new input stream is to be applied. In the same frame, released strokes are unmapped and then each active listening process is called to carry out a respective control operation. When called, the strokes have the correct data for the given frame. The process is repeated for subsequent frames. By carrying out various processes in a sequence of frames, the concept of concurrency is preserved, which is particularly beneficial to multi-touch and multi-user systems. | 06-14-2012 |

| 20120110431 | Touch-Based Annotation System with Temporary Modes - One embodiment provides a system for processing gesture inputs on a touch screen display. The system receives a gesture input on the touch screen display. When the gesture is recognized as invoking an annotation canvas, the system determines the height, width and location of an annotation canvas, and displays the annotation canvas on the touch screen display. Then, in response to an input gesture within the annotation canvas, the system recognizes the gesture as an annotation gesture, and executes the annotation gesture. In response to receiving an input gesture outside of the annotation canvas, the gesture is interpreted by the system as a navigation input. | 05-03-2012 |
