Abstract: A model controller includes a trackball having a spherical surface with one of latitudinal or longitudinal data tracks formed thereon. The model controller includes a base unit including a first image sensor adjacent to the trackball to capture images of the data tracks, wherein the captured images of the data tracks include orientation information to determine an absolute orientation of the trackball.

Abstract: An image displayable at a head-mountable display (HMD) is downsampled to an image pixel representative of the image. The luminance of the image pixel is computed from a color value of the image pixel to determine image brightness. The foveal region of the image is computed from eye-tracking information of the user of the HMD. The foveal region of the image is downsampled to a foveal pixel representative of the foveal region. The luminance of the foveal pixel is computed from a color value of the foveal pixel to determine foveal region brightness.

Abstract: A model controller includes a trackball, a first sensor adjacent to the trackball to detect a first coordinate movement of the trackball, and a second sensor adjacent to the trackball to detect a second and a third coordinate movement of the trackball. The model controller further includes a third sensor to detect movement of the model controller along a surface, and a fourth sensor to detect movement of a wheel coupled to the model controller.

Abstract: A somatosensory feedback system may include at least one somatosensory feedback device to, when actuated, invoke a sensation in a user. The somatosensory feedback system may instruct the at least one somatosensory feedback device to actuate to indicate a passage of time.
