2. Assignment Presentation
1. You are designing the interface for an automated room booking system. List some
general principles for HCI that are relevant to this situation, with a brief indication of
how they would apply.
2. Explain, with explicit reference to attention mechanisms and Fitt’s law, the size and
screen position you would choose for the most frequently used button in an interface.
3. You have been asked to program a software agent that hotel patrons can phone to order
sandwiches:
–Provide a scenario describing an interaction with the system
–Provide a hierarchical task analysis of the sandwich ordering process
4. Using a Keystroke Level Model (KLM), estimate the relative time to type in postcode vs
selecting it from a drop down menu. If each postcode has at most seven characters, how
long would the list of choices on the menu need to be to make menu selection the slower
method?
5. Sketch an STN for interaction with an ATM (cash dispenser). Use this to comment on
what gaps in a user’s conceptual model could cause critical problems in their interaction
with the machine
6. How would you evaluate whether a small change in web-page layout is likely to improve
sales of a particular item? Specify both the data collection method and how you would
assess if any difference was just due to chance, or other factors.
7. Agency: The head of a rail company wants to replace automatic ticket machines with
android ticket-seller. What are the pros and cons of this idea? Is it advisable, given the
current state of technology?
Websites & Ubiquitous: How would you optimize a website for use on small portable
devices?
