Are there any comparisons between the different text entry methods within the restricted interface size afforded by a smart phone.

Specifically between T9 predictive text, on-screen keyboard with auto-correct and Swype and looking at tasks like text messaging or Facebook status / commenting, i.e. small, informal, personal communications that many users perform daily.

"Which method is best" = that's not really answerable here. Can you narrow the question down a bit, perhaps? – DA01 Aug 5 '13 at 22:34
This question would be much clearer and more useful if you simply deleted the first sentence of the last paragraph. – Bennett McElwee Aug 6 '13 at 5:13
Also, you haven't stated your measurement criteria. What do you mean 'better'? What method is faster? What method is the most accurate? Which method suits long periods of writing compared to short text messages? Which method do users feel is easier to learn? Which method do users prefer...? We can't just say one is better than another without having some definition of what to measure against. It's just subjective otherwise. – JonW Aug 6 '13 at 6:13
Edited to ask for studies that compare only – Toni Leigh Aug 6 '13 at 6:35
It's still not clear what it is you're wanting measured. Ability to complete tasks... Accurately? Quickly? Easily? What sort of tasks - long emails? short text-messages? A better question would be 'Do T9 keyboards allow faster composition of long emails compared to Swype?' – JonW Aug 6 '13 at 8:23

I don't think there's a real relevance for T9 on a smartphone because the base reason for its existence doesn't exist on a smartphone. Secondly, there are many methods used for auto-correction on smartphones. As you noted, some do attempt to complete words based on what's already typed. Other's take the context of the word into account and some take common typos ("fat fingers") into account as well.

I'm pretty sure if T9 was good on a smartphone, the original inventor would have carried it over. Instead, he created Swype.
