During the rendering of an image, specific pixels in the image are identified where antialiasing would be helpful. Antialiasing is then performed on these identified pixels, where antialiasing is a technique used to add greater realism to a digital image by smoothing jagged edges. This reduces a cost of performing antialiasing by reducing a number of pixels within an image on which antialiasing is performed.

A method, system, and computer program product for mouse lift cheat detection are provided. In one embodiment, the method includes receiving mouse movement data from a mouse device and determining if a distance represented by the mouse movement data can be performed by a human. When the distance cannot be performed by a human, the method further includes determining if a mouse lift pattern exists. When the mouse lift pattern exists, the method further includes determining if the distance can be performed by a human considering the mouse lift pattern. An alert is generated when the distance represented by the mouse movement cannot be performed by a human whether the mouse lift pattern exists or not. The alert is not generated when the distance represented by the mouse movement data can be performed by a human whether the mouse lift pattern exists or not.

In an embodiment, a modular augmented reality display is provided that incorporates prescription eyewear that can be used separately by the wearer. In an embodiment, an image is generated from a removable display attached to the eyewear and directed into the edge of a prescription lens, which acts as a waveguide. The image is internally reflected within the prescription lens, and is directed to the wearer by an image combiner embedded within the prescription lens. In an embodiment, the augmented reality display includes a wearable belt pouch that includes a battery and support electronics connected to the eyewear so that the weight on the eyewear is reduced.

The disclosure provides a cheating detection strategy for interactive programs, which detects programmatically-generated motion from actual human-generated motion based on a comparison of actual motion data to inferred motion data. The cheating detection strategy uses visual and input information to ensure that the input matches the output to detect and avoid cheating tools positioned in between the input and the output. In one example, the disclosure provide a method of monitoring cheating in interactive programs that includes: (1) receiving actual motion data from a user input device, wherein the actual motion data corresponds to interacting with the interactive program, (2) receiving image data of the interactive program that includes image sequences of the interactive program to display on a screen, (3) comparing the actual motion data to inferred motion data determined from the image sequences, and (4) determining possible cheating based on the comparing.

During the rendering of an image, specific pixels in the image are identified where antialiasing would be helpful. Antialiasing is then performed on these identified pixels, where anti-aliasing is a technique used to add greater realism to a digital image by smoothing jagged edges. This reduces a cost of performing antialiasing by reducing a number of pixels within an image on which antialiasing is performed.

One embodiment of a computer-implemented method for generating mouse sensitivity recommendations includes generating mouse movement data corresponding to one or more mouse movements performed by a user while interacting with a software application; generating a predicted efficiency for each mouse sensitivity level included in a plurality of mouse sensitivity levels based on the mouse movement data; and determining one or more mouse sensitivity levels to provide to the user based on the predicted efficiencies.

A display device for measuring the end-to-end latency of a computing system. The computing system includes an input device, a computing device, and the display device. The display device is directly connected with the input device and receives input data packets generated by the input device in response to received user input events. The display device passes the input packets to the computing device for graphics processing. The display device measures the end-to-end latency comprising the sum of three latencies. A first latency comprises an input delay of the input device. A second latency comprises an amount of time between generation of the input packet and a corresponding change in pixel values caused by the input event at the display device. A third latency comprises a display latency. The display device also displays latency information associated with the measured end-to-end latency.

System-latency-aware display device

The disclosure provides features or schemes that improve a user's experience with an interactive computer product by reducing latency through late latching and late warping. The late warping can be applied by imaging hardware based on late latch inputs and is applicable for both local and cloud computing environments. In one aspect, the disclosure provides a method of operating an imaging system employing late latching and late warping. In one example the method of operating an imaging system includes: (1) rendering a rendered image based on a user input from an input device and scene data from an application engine, (2) obtaining a late latch input from the input device, (3) rendering, employing imaging hardware, a warped image by late warping at least a portion of the rendered image based on the late latch input, and (4) updating state information in the application engine with late latch and warp information.

A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern. Subframes generated based on the sampling order are communicated over a bus along with motion vectors for tiles of the subframes.

Reconstruction for temporally dense ray trace rendering

Perceived clarity of an image presented by a display can be improved using an image stabilization technique to stabilize the image relative to a user's retina. During an illumination period, stabilization actuators are controlled to move a display panel or adjust optical components in the path of light associated with the image to shift the location of the image on the user's retina in response to head or eye movement detected by the system. In some embodiments, a display is configured to illuminate an image, and at least one stabilization actuator is configured to stabilize the image in a retina space associated with a user. Changes in the retina space can be detected by one or more sensors configured to detect a head position of the user and/or an orientation of the user's retina. The image is stabilized in retina space using the stabilization actuators.
