Study shows iPhone on-screen keypad is twice as slow for texting as QWERTY keypad phones

One of the largest complaints posed by new iPhone users is the efficiency of the onscreen keyboard. According to a new study potential iPhone users can now at least quantify that complaint.

User Centric, a usability study group, unveiled the results of its iPhone study today conducted with 20 participants aimed at determining if the iPhone’s touch sensitive onscreen keyboard was as effective as traditional QWERTY keyboard or multitap messaging phones.

The study participants had never used an iPhone and were considered to be heavy text message senders defined as sending at least 15 text messages per week. Out of the twenty participants, ten owned phones with QWERTY keypads and ten owned phones with numeric keypads that used multitap to get the correct characters.

User Centric brought participants in for one-on-one time with a moderator for each of the tests. The test consisted of sending 12 standard text messages created for use in the study with each of the messages being between 104 and 106 characters long. Six of the messages contained instances of proper capitalization, while six had no capitalization and used some abbreviations.

Since none of the participants were iPhone owners, they were each given one minute to get familiar with the touch keypad. This study intended to show the decrease in productivity a new iPhone owner would see if they went from their current phone to the iPhone.

The study concluded that participants that normally used a phone with a QWERTY keypad took almost twice as long to enter the same text messages with the iPhone as they did with their normal phone. Participants who normally used a numeric multitap phone took nearly the same length of time to enter text messages on the iPhone.

“For QWERTY users, texting was fast and accurate. But when they switched to the iPhone, they were frustrated with the touch sensitive keyboard," said Jen Allen, Usability Specialist, User Centric.

Also noted in the study is the fact that many participants hit the wrong keys on the iPhone’s onscreen keyboard and the errors were typically corrected by using the backspace key to delete characters one at a time because of difficulty getting the cursor inserted correctly in the middle of text. Only seven study participants figured out how to use the iPhone’s corrective text feature on their own. Improvement with accuracy while using the iPhone after 30 minutes was noted, but the difference in speed between QWERTY phones and the iPhone persisted.

I have used the iPhone for about as long as the study participants while fiddling with a friends iPhone and using it at the Apple store. I fully agree with the inaccuracy of the keyboard. My fingers were too large and the keys were to close together for me to hit them accurately at any speed. I wished more than once for a stylus to hit the keys with.

"It's important to consider the changes a person has to make when they switch to the iPhone," said Gavin Lew, Managing Director at User Centric. "It should be easy for people to do common tasks, such as text messaging, using the iPhone's less traditional touch interface."

OK, let's recap.

Apple users for years have touted the ease at which you can just pick up and use their products. When I show my Mac friends that I can do most tasks twice as fast as they can with keyboard shortcuts and mouse gestures, they balk. "I don't want to have to learn that crap".

Now, a study comes along that suggests that the new Apple device is a pain in the ass to learn, and it's immediately dismissed? Is the study perfect? No. Does it make a point? Sure. If I were using my device to email or text for 30 minutes and still fumbling around with it, I'd be fuming and cursing for sure.

This will all be moot of course once my thought translator interface is perfected!

I think the most useful result of the study is that multitap users will be able to make the transition to the iphone more easily, where as qwerty users may be slower.

"This study intended to show the decrease in productivity a new iPhone owner would see if they went from their current phone to the iPhone."

I think it's just supposed to show ease of transition for different groups of users. However, the study was laughably small (20 person sample) and they were given only one minute to familiarize themselves with the iphone. This experiment is nothing approaching statistically ideal.

Does anyone remember the HAMBURGER-SHAPED MOUSE?

Oh gosh... after 1 year trying to get used to it, I had to give up. It was very a cute device, though.

I think the word you're both struggling to come up with is "circular" :-).

The study should be about which keyboard is easier to get used to. It should test Apple products if they really are easy to get used to and compare them to a QWERTY keyboard.

Personally, I tested out the iPhone myself at a local AT&T store and I have to admit that it was a pain to use. However, I'm guessing that in a few years, Apple will perfect their keyboard so it is easier to use... how the company will perfect it, I don't know. But what I do know is that when a new and radical product comes onto the market, people have trouble getting used to it, just like with the iPhone.
