Describe how we receive Information through our sensory organs and relate this to HCI. Some description of these organs is necessary. 8. Device experiments to test the properties of (I) short-term memory (ii) long-term Emory.. 9. Find out all you can about natural interfaces. Are there any successful systems? For what applications are these most appropriate? 10. Look at guidelines for use of color. Be able to state the empirical psychological evidence which supports the guidelines. Do the guidelines conflict with any other known guidelines?
What principles of interaction do they support? 11. A group of universities has decided to collaborate to produce an information system to help potential students find appropriate courses.

What transformation or activities are required to make sure the root definition is supported? 3. You have been asked to compare user performance and preferences with two different learning systems, one using hypermedia, and the other sequential lessons.
