According to the studies conducted by Nielsen Norman Group (NNG), much improvement has been noticed in the usability of different applications of iPad in the past one year.
Recently NNG conducted a research, which involved 16 people with some iPad experience. These people were provided 26 iPad applications and six websites to interact with on their iPads. Later users shared their experiences with the researchers.
One major problem users face is with the touchable areas that they say are usually too small and not easy to recognize properly. Links within the text are also too small sometimes. Websites and applications with close touchable areas mostly lead to wrong navigation.
The study found that iPad users try to avoid typing on the touchpad. As a result, most iPad users avoid the registration process in which lot of onscreen typing in required.
It is also noted that a slightly more number of iPad users prefer the landscape (horizontal) mode. Apps which use horizontal navigation in landscape orientation and vertical navigation in portrait orientation confused the user. Apps whose content changes with change in orientation also annoy users.
