Usability Issues in mobile
           web
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.
Usability is invisible
If something is going well, you don’t notice
it
If the temperature in a room is
comfortable, no one complain
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
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.
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 .
Solutions
   Minimize the amount of scrolling required
 to find information
   Include more search options
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.
Solutions
   Separate HTML mark-up language
   Limit the amount of text used
   Arrange information (from most to least
 important)
Impact of KEYPAD
 Text input is difficult on a mobile phone
 considering the user relies on a set of
 numeric keys when writing.
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.
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.
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.
