Estimating our egocentric heading direction is an important component of navigation. Recent studies have explored how inertial cues from the vestibular system and optic flow signals from the visual system interact to improve perceptual precision and accuracy. Heading precision is improved through multisensory integration, whereas heading accuracy is maintained through multisensory calibration m...

This paper describes the mathematical basis and application of a probabilistic model for recovering the direction of camera translation (heading) from optical flow. According to the theorem that heading cannot lie between two converging points in a stationary environment, one can compute the posterior probability distribution of heading across the image and choose the heading with maximum a pos...

A new method for recovery of heading from motion is developed on the basis of Longuet-Higgins and Prazdny's algorithm [Proc. R. Soc. London Ser. B 208, 385 (1980)]. In the algorithm a radial virtual flow field is generated and the difference between the original velocity field and the virtual radial field is computed. The difference vectors, which are directed to the heading point in the projec...

The robot in a highly humanoid appearance, and the ability to play the violin is presented for a robot entertainment and ornamental. By model for keeping moving range of the mechanical structure, a method makes the robot has the possibility of playing the violin. Based on ARM core intelligent control with AHRS is used to realize control of the robot behavior. Finally, the present study realizes...

Past research indicates that observers rely strongly on flow-based and object-based motion information for determining egomotion or direction of heading. More recently, it has been shown that they also rely on displacement information that does not induce motion perception. As yet, little is known regarding the specific displacement cues that are used for heading estimation. In Experiment 1a, w...

in a strapdown magnetic compass, heading angle is estimated using the earth's magnetic field measured by three-axis magnetometers (tam). however, due to several inevitable errors in the magnetic system, such as sensitivity errors, non-orthogonal and misalignment errors, hard iron and soft iron errors, measurement noises and local magnetic fields, there are large error between the magnetometers'...

It has previously been reported that humans can determine their direction of 3D translation (heading) from the 2D velocity field of retinal motion experienced during self-motion through a rigid environment, as is done by current computational models of visual heading estimation from optic flow. However, these claims were supported by studies that used stimuli that contained low rotational flow ...

Computer-generated sequences simulated observer movement toward 10 randomly placed poles, 1 moving and 9 stationary. When observers judged their direction of movement, or heading, they used 3 related invariants: The (a) convergence and (b) decelerating divergence of any 2 poles specified that heading was to the outside of the nearer pole, and the (c) crossover of 2 poles specified that heading ...

Dorsal medial superior temporal cortex (MSTd)'s population response encodes heading direction from optic flow seen during fixation or pursuit. Vestibular responses in these neurons might enhance heading representation during self-movement in light or provide an alternative basis for heading representation during self-movement in darkness. We have compared these hypotheses by recording MSTd neur...
