Abstract: The invention provides a method to stabilize a pointer displayed within an output image. The method enables the user to magnify selected areas within the output image. This allows the user to ‘zoom’ in on areas of interest in the output image, and to make accurate selections with the stabilized pointer. Design features of the method enable pixel and sub-pixel accurate pointing, which is not possible with most conventional direct pointing devices. The invention can be worked for 2D and 3D pointers.

Abstract: A method maps positions of a direct input device to locations of a pointer displayed on a surface. The method performs absolute mapping between physical positions of a direct input device and virtual locations of a pointer on a display device when operating in an absolute mapping mode, and relative mapping between the physical positions of the input device and the locations the pointer when operating in a relative mapping mode. Switching between the absolute mapping and the relative mappings is in response to control signals detected from the direct input device.

Abstract: A method, computer system and computer program is provided for using a suggestive modeling interface. The method consists of a method of a computer-implemented rendering of sketches, the method comprising the steps of: (1) a user activating a sketching application: (2) in response, the sketching application displaying on a screen a suggestive modeling interface; (3) the sketching application importing a sketch to the suggestive modeling interface; and (4) the sketching application retrieving from a database one or more suggestions based on the sketch. The method is operable to allow a user interactively using the sketching application to create a drawing that is guided by the imported sketch by selectively using one or more image guided drawing tools provided by the sketching application. The present invention is well-suited for three-dimensional modeling applications.

Abstract: Touch interaction with a curved display (e.g., a sphere, a hemisphere, a cylinder, etc.) is enabled through various user interface (UI) features. In an example embodiment, a curved display is monitored to detect a touch input. If a touch input is detected based on the act of monitoring, then one or more locations of the touch input are determined. Responsive to the determined one or more locations of the touch input, at least one user UI feature is implemented. Example UI features include an orb-like invocation gesture feature, a rotation-based dragging feature, a send-to-dark-side interaction feature, and an object representation and manipulation by proxy representation feature.

Abstract: A machine learning model is trained by instructing a user to perform proscribed gestures, sampling signals from EMG sensors arranged arbitrarily on the user's forearm with respect to locations of muscles in the forearm, extracting feature samples from the sampled signals, labeling the feature samples according to the corresponding gestures instructed to be performed, and training the machine learning model with the labeled feature samples. Subsequently, gestures may be recognized using the trained machine learning model by sampling signals from the EMG sensors, extracting from the signals unlabeled feature samples of a same type as those extracted during the training, passing the unlabeled feature samples to the machine learning model, and outputting from the machine learning model indicia of a gesture classified by the machine learning model.

Abstract: The system displays an image portraying a virtual space as viewed by a virtual camera at a first location on a spatially navigable camera surface within the virtual space. A user begins a drag operation. Based on the dragging, the virtual camera is spatially translated from the first location on the spatially navigable region to a second location on the spatially navigable region. The orientation of the virtual camera at the second location may be automatically set to either point towards the pre-defined look-at point or to point in a direction normal to the spatially navigable region at the second location. The system then displays an image portraying the virtual space in accordance with the location and orientation of the virtual camera at the second location in the spatially navigable camera surface. While the drag operation continues, the system determines that further translating the virtual camera would place the virtual camera beyond the spatially navigable region. In response, the system begins displaying a transition, which may be an interpolated animation of the virtual camera, an animation semi-transparently blended with a slate, a pre-authored animation of the virtual camera, or other visual effect. While further continuing to drag, and based on the same, the system either advances display of the transition, reverses display of the transition, or otherwise temporally controls the display of the transition.

Abstract translation: 该系统显示在虚拟空间内的空间可导航的相机表面上的第一位置处的虚拟照相机所观察到的描绘虚拟空间的图像。 用户开始拖动操作。 基于拖动，虚拟相机在空间上可导航区域上的第一位置被空间转换到空间可导航区域上的第二位置。 可以将第二位置处的虚拟相机的方向自动设置为指向预定义的观看点或指向与第二位置处的空间可导航区域垂直的方向。 然后，系统根据虚拟相机在空间可导航相机表面的第二位置处的位置和方位来显示描绘虚拟空间的图像。 当拖动操作继续时，系统确定进一步翻译虚拟相机将使虚拟相机超出空间可通航区域。 作为响应，系统开始显示转换，其可以是虚拟相机的内插动画，与平板半透明混合的动画，虚拟相机的预创作动画或其他视觉效果。 在进一步继续拖动的同时，该系统可以提前显示转换，反转转换的显示，或以其他方式临时控制转换的显示。

Abstract: The present invention is a system that creates a volumetric display and a user controllable volumetric pointer within the volumetric display. The user can point by aiming a beam which is vector, planar or tangent based, positioning a device in three-dimensions in association with the display, touching a digitizing surface of the display enclosure or otherwise inputting position coordinates. The cursor can take a number of different forms including a ray, a point, a volume and a plane. The ray can include a ring, a bead, a segmented wand, a cone and a cylinder. The user designates an input position and the system maps the input position to a 3D cursor position within the volumetric display. The system also determines whether any object has been designated by the cursor by determining whether the object is within a region of influence of the cursor. The system also performs any function activated in association with the designation.

Abstract: The present invention is a system that allows a user to physically rotate a three-dimensional volumetric display enclosure with a corresponding rotation of the display contents. The rotation of the enclosure is sampled with an encoder and the display is virtually rotated by a computer maintaining the scene by an amount corresponding to the physical rotation before being rendered. This allows the user to remain in one position while viewing different parts of the displayed scene corresponding to different viewpoints. The display contents can be rotated in direct correspondence with the display enclosure or with a gain (positive or negative) that accelerates the rotation of the contents with respect to the physical rotation of the enclosure. Any display widgets in the scene, such as a virtual keyboard, can be maintained stationary with respect to the user while scene contents rotate by applying a negative rotational gain to the widgets. The rotation can also be controlled by a time value such that the rotation continues until a specified time is reached or expires.
