Illusory position shifts induced by motion suggest that motion processing can interfere with perceived position. This may be because accurate position representation is lost during successive visual processing steps. We found that complex motion patterns, which can only be extracted at a global level by pooling and segmenting local motion signals and integrating over time, can influence perceiv...

Omni-directional images are widely used in image-based walkthrough applications, in which camera pose recovery is one of the initial and important processes. Existing methods may recover camera pose of omnidirectional images from lines. However, it may not work well when there is insufficient scene structure in the images. In addition, existing methods involve non-linear optimization and iterat...

INTRODUCTION The symptoms associated with chronic peripheral vestibulopathy exert a negative impact on the independence and quality of life of these individuals, and many individuals continue to suffer from these symptoms even after conventional vestibular rehabilitation. OBJECTIVE To evaluate the acute effect of an anchor system for balance evaluation of patients with chronic dizziness who f...

In this paper we analyze the characteristics of vehicle mobility and propose a novel Mobility Prediction Progressive Routing (MP2R) protocol for Inter-Vehicle Communication (IVC) that is based on cross-layer design. MP2R utilizes the additional gain provided by the directional antennas to improve link quality and connectivity; interference is reduced by the directional transmission. Each node l...

Neurons throughout the rat vibrissa somatosensory pathway are sensitive to the angular direction of whisker movement. Could this sensitivity help rats discriminate stimuli? Here we use a simple computational model of cortical neurons to analyze the robustness of directional selectivity. In the model, directional preference emerges from tuning of synaptic conductance amplitude and latency, as in...

This paper proposes new method for object reference which enables a person to find surrounding objects and develops a navigation system named CoCo. CoCo employs an ultrasonic directional speaker with a rotating base. Ultrasonic wave transmitted by an ultrasonic directional speaker is converted to audible sound when it reflects on floor, wall, or object. Based on this property, CoCo can emit aud...

A goal in the field of nanoscale optics is fabrication nanostructures with strong directional light scattering at visible frequencies. Here, synthesis Mie-resonant core–shell particles overlapping electric and magnetic dipole resonances spectrum demonstrated. The core consists silicon surrounded by a lower index oxynitride (SiOxNy) shell an adjustable thickness. Optical spectroscopies coupled t...

This paper proposes a novel fingerprinting localization scheme, called FLCDA (Fingerprinting Localization with Cruciate Directional Antennas), using only one anchor node equipped with four directional antennas whose orientations are perpendicular to adjacent ones. The proposed FLCDA consists of two phases. In the RSSI gathering phase, a sensor node is placed at reference positions to send signa...
