Human Eye interaction with Computer

                 Human  Eye interaction with Computer


Human-computer Interaction (HCI) is concerned with design, evaluation and
implementation of interactive computing systems for human use and with the
study of major phenomena surrounding them. It deals with the interaction be-
tween users and computers. The basic goal of HCI is to improve this interaction
by making computers more usable and receptive to the user's needs. That means
that we want to make the barrier between the human's cognitive model of what
they want to accomplish and the computer's understanding of the user's task as
minimal as possible.
The central character for interactive systems is the human. In order to de-
sign a system which full_ls the requirements of the user we need to understand
capabilities and limitations of the human body , human's thinking as well as
human's psychology.


Input-Output Channels of Human Eye:

A person interacts with a computer through sending and receiving information.
The user receives information as input which is output of the computer and
can response by sending information as input to the computer. That means the
human's input is the computer's output and vice versa. Human can receive infor-
mation mainly through the senses. We call these senses human input channels.
There are _ve di_erent input channels, vision, hearing, touch, taste and smell.
The _rst three channels are the most important for HCI purposes. Human out-
put on the other side occurs through motor control of human body parts like the
limbs, _ngers, eyes, head and the vocal system. Of course the _ngers play the
most important role for interacting with a computer. We need them for typing
at the keyboard and controlling the mouse. When you use an application at a
computer, you interact through an interface with menu bars, icons and windows.
By interacting with the interface we receive information mainly through sight.
To understand human sight we will have a closer look at the visual input channel

now.

Project Proposal: Project (Contact Information Diary)

Introduction :
Purpose :
          Phone and personal information diary which include the phone number and personal information in which e-mail address include address in which we can include the data of that personal by giving as input. In which we can add, delete and search that person’s data which we want.

          In now days this is in great demand because every person want to save the information about other person like number e-mail, address, mobile number and so many other thing.

Software Features :
Name :
          In this program or software we can add the names of that person’s.

Address :
          In this section of program or software we can add or enter the address of any person which we want to enter.
Mobile Number :
          As we know that in now days mobile number are very important so we add this feature of adding mobile number or lane line number of that person and we can save it and after this we can see that number every time.
E-mail :
          E-mail now a days are very important means of communication we also add the features of e-mail address of a person.
Scope :
          It is very important for the persons to save this contacts, address, e-mail and mobile numbers of other persons.
Uses :
          It can be used as diary because it meet the requirements of many people like business and high profile person because it help then to save the number and e-mail address of different companies and different peoples. Diary is essential part of ours life or business man’s life because it help them in so many ways.
