  • Patent number: 11978169
    Abstract: A wrist-pose isolation system can infer a wrist pose (e.g., the user's hand position relative to her forearm) and can reduce wrist-induced jitter for projection casting in an XR environment. A user's projection cast can be determined as a combination of a “low-wrist contribution” component (e.g., a body-and-arm component) and a “high-wrist contribution” component (e.g., the pose of the wrist with respect to the arm). Using input from a gesture-tracking system, the contribution of the user's wrist pose to the user's current projection cast is calculated as a “wrist-contribution vector.” A projection cast direction can be determined as the interpolation of the current low-wrist contribution component and the high-wrist contribution component. This interpolation can be performed by weighting each by a specified amount and combining them.

    Abstract: Methods are described for driving an electro-optic display having a plurality of display pixels. Each of the display pixels is associated with a display transistor. The method includes the following steps in order. A first voltage is applied to a first display transistor associated with a first display pixel of the plurality of display pixels. The first voltage is applied during at least one frame of a driving waveform. A second voltage is applied to the first display transistor associated with the first display pixel. The second voltage has a non-zero amplitude less than the first voltage and is applied during the last frame of the driving waveform. The amplitude of the second voltage is based on a voltage offset value and a sum of remnant voltages each frame of the driving waveform contributes to the first display pixel when the first voltage is applied to the first display transistor.
