Abstract: The present application discloses a mask pattern determination method, a mask pattern determination apparatus, a medium, and a product, which are applied to the technical field of semiconductor. In this method, etching bias is determined by a first etch pattern and a first photolithography pattern, and the first etch pattern is obtained by merging the first sub-image and the second sub-image. The first sub-image is generated by a physical effect simulation unit based on the first photolithography pattern, and the second sub-image is generated by a neural network unit based on the first photolithography pattern. The neural network unit can effectively improve a data fitting ability of an etching model, thereby improving an accuracy of the etching model to obtain an accurate first etching bias. Meanwhile, the physical effect simulation unit of the etching model simulates an actual physical effect, which can prevent the etching model from over-fitting.

Abstract: A computerized method is provided for user authentication using hand gestures. Multiple points on a user's hand can be tracked using cameras or various sensors and the motion of those points in space and relative to each other can used to create gesture-based passwords. Such user authentication techniques have advantages in augmented and virtual reality applications where traditional text-based passwords may be difficult. Gesture-based user authentication can be augmented with physical characteristics of the specific user's fingers and hands including size, shape, and distinguishing marks to enhance security.

Abstract: The present application discloses a mask pattern determination method, apparatus, medium, and program product, which are applied to the technical field of semiconductor. In the mask pattern determination method provided in the present application, a target mask pattern is determined based on a plurality of second sampling points, and the second sampling points are obtained by performing etching bias correction on a first sampling point based on a first etching deviating data between a position corresponding to a first sampling point on the first photolithography pattern and a position corresponding to the first sampling point on the first etch pattern. The first sampling point may represent a pattern contour of the first target etch pattern. Therefore, in the present application, an etching bias of a curved contour may be corrected relatively accurately by correcting the plurality of sampling points individually.

Abstract: A computerized method is provided for augmenting web pages and other content displayed on a traditional monitor with content in an AR environment. In various embodiments, a user can interact with objects in the AR environment to trigger changes to content or objects in the traditionally displayed content on the monitor. In some embodiments, the traditionally displayed content can automatically trigger AR supplementation or may detect private or sensitive information and automatically transfer that information from the traditional display to the AR environment to prevent unwanted viewing by third-parties.

Abstract: Methods and systems for automated testing of virtual reality software applications using robotic devices include a server that converts a test workflow description into a sequence of actions in a format interpretable by a robotic device. The server transmits the sequence of actions to the robotic device. For each action in the sequence of actions, the server a) receives, from the robotic device, execution data corresponding to an outcome of execution of the action by the robotic device; b) captures, from a virtual reality device, one or more of image data and vector data corresponding to a current state of a virtual reality software application; c) analyzes one or more of the image data, the vector data, and the execution data to determine whether the robotic device successfully executed the action; and d) upon determining that the robotic device successfully executed the action, repeats steps a)-d) for the next action.

Abstract: Methods and apparatuses are described for generating and manipulating 3D objects in a 3D environment of an alternative reality software application. A server retrieves a data set comprising data elements, each having one or more attributes. The server generates, for each data element, a virtual object, each virtual object positioned inside a virtual container and located in proximity to a center of the virtual container. The server attaches virtual magnets to an exterior surface of the virtual container, each magnet associated with a data filter value and an attraction value. The server determines, for each virtual object, a movement distance and a movement speed in relation to each virtual magnet based upon the data filter value and the attraction value for the virtual magnet. The server moves at least a portion of the virtual objects to a new location based upon the movement distance and movement speed.

Abstract: Methods and apparatuses are described for providing a thumb scroll user interface element in a computerized visual environment. A viewing device displays a graphical user interface within a three-dimensional space that includes surface planes each associated with a graphical thumb scroll element. A sensor device captures a location of the user's hand within the three-dimensional space and a gesture of the user's hand. A computing device detects that the location is within a defined zone around one of the graphical thumb scroll elements and activates the thumb scroll element associated with the defined zone. The computing device identifies the gesture, determines a scroll speed based upon a speed of the identified gesture, and determines a scroll direction based upon a direction of the identified gesture. The computing device changes characteristics of graphical content in the surface plane based upon at least one of: the scroll speed or the scroll direction.
