Usability engineering ->Usability issues in mobile web

1. Usability Issues in mobile
web

2. Introduction
There were 40.04 million users accessing the
mobile Internet at least once a month and
number increased by 33% over a period of
year.
As the prevalence of PDA and other smart
devices with Internet connectivity increase,
so does the need for attention to the
usability of these devices.

3. Usability is invisible
If something is going well, you don’t notice
it
If the temperature in a room is
comfortable, no one complain

4. Problems
Mobile devices present several unique
problems in addition to the standard usability
issues that challenge Web designers.
Issues associated with mobile devices are a
function of the devices
Small Size
low resolution screens

5. limited input option
slow computer hardware
slow or sometimes unreliable connectivity
Most sites are designed for full scale PCs
or laptops and they do not take the mobile
user into account.

6. Impact of Low Resolution
The high resolution screens were spend less
time scrolling then there low resolution.
Mobile users spend more time attempting to
locate information rather than simply
browsing .

7. Solutions
Minimize the amount of scrolling required
to find information
Include more search options

8. Impact of Limited Screen Size
One of the most salient usability issues for
the mobile Web is the limited screen size.
There are no standard screen sizes, or
display parameters
Mobile users lack the ability to scan an
entire page to locate information.

10. Solutions
Separate HTML mark-up language
Limit the amount of text used
Arrange information (from most to least
important)

11. Impact of KEYPAD
Text input is difficult on a mobile phone
considering the user relies on a set of
numeric keys when writing.

12. Solutions
Signing in – A user should be
automatically signed in when possible.
URLs – Should be fairly short.
Search criteria – While entering
search criteria, the system should support
common abbreviations as far as possible.

13. Numeric keys –The natural way of
interaction with a phone is numeric so
fields should be numeric if they can and
use of the keypad when navigating through
a particularly long page should be
supported.

14. Conclusion
The mobile Web poses several unique
challenges to usability researchers and
designers.
These challenges are compounded by the
mobile Web environment being only a part of
the Web universe.
What may be most needed in mobile/Web
usability is a standardization of the usability
process so comparisons can be easily made
between devices and systems.
