For Teacher Use Only
Find a handheld device (e.g., a PDA, mobile phone) and examine how it has been
designed, paying particular attention to how the user is meant to interact with it.
a.From your first impressions, write down what first comes to mind as to what is good
or bad about the way the device works. Then list (i) its functionality and (ii) the range
of tasks a typical user would want to do using it. Is the functionality greater, equal, or
less than what the user wants to do?
b.Based on your study, compile your own set of usability and user experience goals that
you think will be useful in evaluating the device. Decide which are the most important
ones and why.
c.Translate the core usability and user experience goals you have selected into two or
three questions. Then use these questions to assess your device (sample questions: what
mechanisms have been used to ensure safety? Is it fun to use, etc.).
d.Evaluate the device using Norman’s design principles.
Answer:-
Communication Devices:The hardware used to transmit data, instructions, and
information between a sending and receiving device is called a communication device.
Goods:
•
•
•
•
•
more efficient.
faster method of cummunication during emergencies.

Functionality:
Modem stands for modulation and demodulation. A modem is a device that switches
digital signal into analog and analog signal into digital. Modem forwards and accept data
from one computer to another using telephone lines. It is necessary that both the sending and
receiving computer must hold modems
