1. The superior colliculus has been studied in alert cats which were restrained and whose head and eye movements were monitored.2. Microstimulation within the rostral part of the colliculus, which represents the central 25 deg of the visual field, evokes saccadic eye movements that carry the area centralis to that region of visual space previously occupied by the receptive fields of the cells t...

The aim of this present study is to design a wheelchair with sensor communicator system that could operate the wheelchair with the help of head movement. The targeted people for this study are handicapped person and quadriplegic and disabled person as this could be operated easily through head motion sense. Present study also focuses on reducing the overall cost to make it economically availabl...

In this paper we study the human head movement, when the head shifts its orientation between two possible heading directions, as a simple mechanical control system. Head movements obey Donders’ constraint (as opposed to the Listing’s constraint for eye movement), which states that the allowed orientations of the head are obtained by rotating a fixed ‘primary heading direction’ by a subclass of ...

Constructing three-dimensional model from two-dimensional images is an old problem in the area of computer vision. There are many publications and our approach is specifically designed for constructing the depth map of a human face, based on the head movement in a monocular setting. In our example, along with the front view image of the user, three additional images with various head movement a...
