چکیده

We propose an integrated model of the saccadic circuitry involved in target selection and motor command. It includes the Superior Colliculus and the Basal Ganglia in both cortical and subcortical loops. This model has spatial and feature-based learning capabilities which are demonstrated on various saccade tasks on a robotic platform. Results show that it is possible to learn to select saccades based on spatial information, feature-based information and combinations of both, without the necessity to explicitly pre-define eye-movement strategies.

An Experimental Study on Blinking and Eye Movement Detection via EEG Signals for Human-Robot Interaction Purposes Based on a Spherical 2-DOF Parallel Robot

Blinking and eye movement are one of the most important abilities that most people have, even people with spinal cord problem. By using this ability these people could handle some of their activities such as moving their wheelchair without the help of others. One of the most important fields in Human-Robot Interaction is the development of artificial limbs working with brain signals. The purpos...

Spatial Attention and Saccadic Camera Motion

An important aspect of computer-controlled camera motion systems is that of the generation of saccadic movements, which shift the camera gaze quickly from one xation position to another. Recent psychophysi-cal experiments suggest that there exists a causal connection between spatial shifts in visual attention and the production of saccadic eye movements in humans. Motivated by this experimental...

Kinematic Calibration for Saccadic Eye Movements

The visual perception system of humanoid robots should provide sensorial information that fulfills the requirements imposed by perceptual tasks in natural environments. One prerequisite for such systems is the ability to observe the environment by actively moving its visual sensors. This ability allows to implement two essential behaviors for a cognitive visual system: smooth pursuit and saccad...

Retinally-generated saccadic suppression of a locust looming-detector neuron: investigations using a robot locust.

A fundamental task performed by many visual systems is to distinguish apparent motion caused by eye movements from real motion occurring within the environment. During saccadic eye movements, this task is achieved by inhibitory signals of central and retinal origin that suppress the output of motion-detecting neurons. To investigate the retinally-generated component of this suppression, we used...

Design of a Humanoid Robot Eye

This chapter addresses the design of a robot eye featuring the mechanics and motion characteristics of a human one. In particular the goal is to provide guidelines for the implementation of a tendon driven robot capable to emulate saccadic motions. In the first part of this chapter the physiological and mechanical characteristics of the eyeplant1 in humans and primates will be reviewed. Then, t...
