Problem
Statement:
In HCI, Usability is concerned
with making artifacts that is easy to use and learned for humans. Consider a scenario you are assigned a task
to design a medical diagnostic imaging system that is a computerized tomography' (CT) scan system.
This system uses a computer that takes data from several X-ray images of
structures inside a human's body and converts them into pictures on a
monitor. This system should be useful for doctor’s operators or its other
users .As this system gets X-rays from various parts of body and also omit
radiations that may be harmful for its users. There is also need to
concentrate not only on its functional and usability requirement as well as
prevent its users form hazardous effects on their health or life.
Questions:
1.
You are required to map the goals that make system
useable and safe for its users according to the above scenario
2.
You also need to
identify the cognition modes with justification for you and said system
users.
NOTE:
ü Be precise in your answer. Write inn your own words
according to the problem statement .Don’t write unnecessary or irrelevant
information it will mark zero.
ü Do not put any query on MDB related to assignment, if you
have any query then email at CS408@vu.edu.pk
Deadline:
Your assignment must be uploaded
on VULMS on or before Thursday 21st May 2015.

System Usability is normally intended to easy to learn, effective to use and easy to handle from user point of view. A well usable system always wins due to their simplicity, easy to use and learn. It makes interaction from people to system more simple and useful.
ReplyDelete• We can prevent the user from making thoughtful error by falling the risk of wrong keys/buttons being incorrectly activated.
• We can providing users with many resources of retrieval should they make errors. Save interactive systems should be engaged with like shielded door may be placed to protecting the user from rays
By using the new perception we can see, understand, act, and react according to events effectively and effortlessly. It also required peak level knowledge and planning. Before using X-ray system we need much more attention on how to use and understand the system, their safety measures etc. we also required to memorize the safe operation at the end. So in experimental cognition we required peak level skill and understanding to system. This helps us to use an X-ray system more safely and without any hazards.
