Dear Tirthankar
Your work sounds very interesting. I will be glad to get your paper
collection. Thanks. AMI

> Dear Dr. Mohsaiov
> I am Tirthankar Sengupta from the New Jersey Institute of Technology. At
present I am working on relationship of eye and mouse movements. My interest
is in obtaining the relationship of cognitive processing and the subsequent
motor action manifested in mouse movements in the area of computer
interaction. However the study does not restrict itself to the computer but
also to the different forms of products which bear an interface. I am
studying the the eye movements under different task situations like task
understanding, formalization of plan, execution of the actions and then the
subsequent evaluation. In different situations the mouse and the eye
obviously behave differently however the task has a dominent effect on the
movements rather than the interface.
> I would like to know what might be the different methods to analyse the
eye movement data obtained as a series of coordiantes in time. Cluster
analysis techniques are most popular. Identifying number of saccades based
on velocity and gaze durations based on localization of fixation is also
another method.
> Thanks for the mention of papers like the behavioral model of vision
perception and recognition. I will mail you some of the references I have
collected which studies eye movements and cognitive processes. I think you
might be aware of this book.:
> Eye movements and Psychological Processes edited by Richard A. Monty and
John W. Sanders. this is a collection of studies eye movements were studied
for understanding cognitive processes.

> In particular the results of Noton and Stark prompted the consideration of
eye movement scanpaths as behavioral programs for recognition. Rybak et al.
have used the behavioral approach and implemented the where and what of a
scan-path for their object recognition space-variant system. Rybak et al.
suggest that the findings of Yarbus 1967 are in support of their approach.

> During my attempt to look into computer learning and detection of
partially occluded objects, using a retina-like model, I have started to
wonder about Rybak's approach. It appeared to me that because of the unknown
whereabouts of the occlusion the behavioral approach should need a
modification. Furthermore, I do not find Yarbus results in support of the
behavioral approach.

> I am interested to know if any of the colleagues reading this message can
provide me with more insight. I know from reading a 1995 review of E. Kowler
that there are works that link eye-movements to cognition. I am
in-particular interested in:
>
> 1. A recent review on eye-movements (preferable with a comparison on
behavior vs. cognitive approach)
> 2. Eye-movements (saccades) recordings that compare results of object
learning stage with those of object recognition stage (Preferable with
changing level of occlusion).
> 3.In addition I would like to know if there are works that combine eye
movement recordings with neural activity recordings, both in general and in
particular to the above topic.

> I will be glad to know if there are any colleagues who are currently doing
related research (items 2 &3). Else to find colleagues who are interested in
collaboration on the described topic.
